One of today’s great challenges is radical process improvement. TRIZ (theory of inventive problem solving) could help to resolve this. This study aims to answer the following research question: Which tool of TRIZ is best for process improvement? To answer this, a systematic literature review was conducted, and the gathered data were analyzed. The main focus was on the tools, the rate of improvement, the improved parameters, and the combination of tools. The results show that the technical contradiction with inventive principles should be easy to use and provide sufficient results. If the technical contradiction is not enough or the process is too complex, an algorithm or framework to use more advanced tools of TRIZ should be used. That should help to resolve the most challenging problems related to radical process improvement. Full article

Interdisciplinary research (IDR) is essential for addressing complex global challenges that surpass the capabilities of any single discipline. However, measuring interdisciplinarity remains challenging due to conceptual ambiguities and inconsistent methodologies. To overcome these challenges, we propose a deep learning approach that quantifies interdisciplinarity in scientific articles through semantic analysis of titles and abstracts. Utilizing the Semantic Scholar Open Research Corpus (S2ORC), we leveraged metadata field tags to categorize papers as either interdisciplinary or monodisciplinary, establishing the foundation for supervised learning in our model. Specifically, we preprocessed the textual data and employed a Text Convolutional Neural Network (Text CNN) architecture to identify semantic patterns indicative of interdisciplinarity. Our model achieved an F1 score of 0.82, surpassing baseline machine learning models. By directly analyzing semantic content and incorporating metadata for training, our method addresses the limitations of previous approaches that rely solely on bibliometric features such as citations and co-authorship. Furthermore, our large-scale analysis of 136 million abstracts revealed that approximately 25% of the literature within the specified disciplines is interdisciplinary. Additionally, we outline how our quantification method can be integrated into a TRIZ-based (Theory of Inventive Problem Solving) methodological framework for cross-disciplinary innovation, providing a foundation for systematic knowledge transfer and inventive problem solving across domains. Overall, this approach not only offers a scalable measurement of interdisciplinarity but also contributes to a framework for facilitating innovation through structured cross-domain knowledge integration.

Currently, in the grinding areas of Peruvian mining operations, there are linings made of various materials such as rubber and steel, all of which have a limited lifespan and eventually wear out. Understanding the wear behavior of these linings has a direct impact on mill performance. There are several solutions for measuring wear, making wear projections, and, most importantly, knowing the replacement date so that the mining company can schedule a plant shutdown. However, these solutions are not swift, as traveling to the mine, returning to the company, processing the data in software, and generating reports take 3 to 10 days depending on the workload of each supplier of these linings. Mining companies seek solutions to monitor the condition of their linings and avoid plant shutdowns as they disrupt production. The primary objective of this tool is to quickly and accurately predict the wear and removal of mill linings with user safety as a top priority. The product design and development process followed the methodology proposed by Ulrich and Eppinger, which includes (a) identifying customer needs, (b) planning, (c) developing product concepts, (d) system-level design, (e) detailed design, and (f) testing and refinement. Key metrics for design were defined through 50 surveys. Additionally, two focus groups with mill lining experts and user testing were conducted, allowing for the refinement and validation of the initial concept. The tool prototype was modeled in 3D, sensors and other electrical mechanisms were purchased, and an LED screen was programmed for data reading. Methodologies such as TRIZ, SCAMPER, and Canva were incorporated, facilitating a well-designed product with attention to detail. Finally, the final characteristics of the digital comb, ranging from 10′ to 25′, were defined and tested on mill linings, and with the help of the Weir Projection application, wear history and projections were rapidly generated. When compared with other measurement tools, minimal differences were found within a range of ±2 mm. Therefore, it is concluded that the prototype assists in quickly scheduling mill lining requirements in advance. Full article

This study examines the enhancement of the mechanical strength of polymer resins through reinforcement with synthetic (glass) and natural (hemp, jute) fibers, using the TRIZ-ARIZ methodology to optimize composite design for improved mechanical properties, sustainability, and economic efficiency. Mechanical testing, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) were conducted to evaluate the properties of the composite materials. Regarding tensile strength testing, the results showed the following: jute fiber achieved the best results, with a maximum tensile values of 43.75 MPa (partial reinforcement) and 43.53 MPa (complete reinforcement); glass fiber recorded maximum tensile values of 34.55 MPa (partial reinforcement) and 34.52 MPa (complete reinforcement); and hemp fiber yielded maximum tensile values of 24.98 MPa (partial reinforcement) and 24.86 MPa (complete reinforcement). The mechanical performance of partial reinforcements (in the area of maximum stress) was similar to that of complete reinforcements, enabling a reduction in material usage by up to 60%. The thermal analysis (TGA) results demonstrated that glass fiber-reinforced composites exhibit high thermal stability, with mass loss starting at 320 °C and a residual mass of 8.02%; for other composite materials, thermal degradation begins at 305 °C, with a residual mass of 3.69%; in jute fiber-reinforced composites, thermal degradation starts at 300 °C, with a residual mass of 3.71%. SEM analysis generally revealed good fiber–matrix adhesion, while defects such as voids or detached fibers contributed to reduced mechanical strength. These results demonstrate that natural fiber-reinforced composite materials, particularly those reinforced with jute, can be used in sustainable engineering applications. They also show that localized reinforcement provides high performance with minimal resource consumption. Full article

In modern, fast-paced lifestyles, food containers have become a popular solution for quick meals; however, they have significantly contributed to the increase in plastic packaging waste, which poses a substantial environmental risk. The prevalent use of non-biodegradable plastic containers exacerbates plastic pollution, contradicting government regulations designed to reduce plastic usage and promote sustainability. To address these issues, this study integrates TRIZ, ergonomics, inherent safety, and universal design methodologies, with an emphasis on sustainability. First, the technical contradiction matrix from TRIZ is applied to identify parameters for improvement without inducing negative side effects. Ergonomics principles ensure the development of user-friendly designs, while inherent safety and universal design approaches aim for accessibility and full biodegradability. Through a systematic innovation design process, this research proposes a biodegradable food container capable of decomposing entirely into particles and water within one month, blending naturally with the soil without compromising functionality. Moreover, the container incorporates a quick-alignment mechanism and an intuitive sealing design that ensures airtightness and spill prevention. As a result, the product not only meets user demands but also addresses pressing environmental concerns, aligning with global sustainability goals. Full article

We propose the DIKWP-TRIZ framework, an innovative extension of the traditional Theory of Inventive Problem Solving (TRIZ) designed to address the complexities of cognitive processes and artificial consciousness. By integrating the elements of Data, Information, Knowledge, Wisdom, and Purpose (DIKWP) into the TRIZ methodology, the proposed framework emphasizes a value-oriented approach to innovation, enhancing the ability to tackle problems characterized by incompleteness, inconsistency, and imprecision. Through a systematic mapping of TRIZ principles to DIKWP transformations, we identify potential overlaps and redundancies, providing a refined set of guidelines that optimize the application of TRIZ principles in complex scenarios. The study further demonstrates the framework’s capacity to support advanced decision making and cognitive processes, paving the way for the development of AI systems capable of sophisticated, human-like reasoning. Future research will focus on comparing the implementation paths of DIKWP-TRIZ and traditional TRIZ, analyzing the complexities inherent in DIKWP-TRIZ-based innovation, and exploring its potential in constructing artificial consciousness systems.

In this article, an Advanced Air Mobility (AAM) platform focused on search and rescue applications is discussed and analyzed from a systems thinking perspective. By applying two systems thinking tools, namely Mind Map and TRIZ, the strong interactions within the constituent parts that make up the system’s whole are examined with the aim of providing a comprehensive roadmap for a proposed Advanced Air Mobility Post-Disaster Response (AAMPDR) system. Furthermore, two problems are discussed to demonstrate the application of the TRIZ technique. The first is in regards to a clause in the AGL rule that could present operational risks to the AAM’s airframe, while the second relates to a potential conflict ensuing from the advent of the 5G C-band and its effect on the AAM altimetry. The resulting solutions to resolve these conflicts using this same technique are also discussed, firstly by taking into account the mean sea/water level as a reference for vertical height within the provisions of the Federal Aviation Regulation requirements, and secondly by applying segmentation of the mission profile as well as a multi-stage frequency designation for each segment depending on a threshold vertical distance. Finally, this study demonstrated that Mind Map and TRIZ can be effective techniques in the early stages of conceptual model development for an AAM system applied to post–disaster response. Furthermore, that the contradictions tool of TRIZ can also be utilized in resolving those potential conflicts identified in relation to the system of interest. To this end, this paper proposes the amendment of the current Part 107 rule to include the term Above Mean Sea (or Water) Level (AMS/WL), a critical yet missing piece of the system requirements that engineers should take into account in future AAM system designs.

This study investigates the innovative design of a bicycle saddle by incorporating sustainable ergonomics, universal design principles, and systematic innovation methods. Initially, the literature related to bicycle saddle design and its impact on the human body during riding was analyzed. The TRIZ contradiction matrix was then used to identify relevant invention principles, which served as references for the innovative design of the bicycle saddle. Biomechanics and the human–machine system analysis within human factors engineering were applied to ensure the innovative design is ergonomic and user-friendly. The design features a horizontally expandable and foldable bicycle saddle, enhancing its adaptability and sustainability. Universal design principles were applied to make the innovative design more accessible to the general public, and the prototype was simulated using Inventor drawing software. The research results include: (1) An innovative bicycle saddle design with horizontal expansion and folding functions is proposed. This design divides the saddle into three components, enabling the left and right parts to expand or retract based on user preferences. (2) A bicycle backrest design featuring vertical adjustability is introduced. It incorporates a quick-release adjustment mechanism at the junction of the backrest and saddle, allowing users to freely adjust the backrest height. (3) A quick-operation bicycle saddle design is presented, utilizing quick-release screws to facilitate the swift operation of the horizontal expansion and folding mechanisms. This validation method confirmed that the innovative design meets both sustainable ergonomic standards and user expectations. The systematic innovation approach used in this study can serve as a valuable reference for future research and design applications. Full article

Traditional door mechanisms in public spaces, such as knob locks and standard handles, require manual contact, making them prone to contamination and posing significant health risks. To address the critical need for a safer and more hygienic solution, this study aimed to develop an innovative foot-operated door mechanism that is accessible and intuitive for all users. The study applies the Theory of Inventive Problem Solving (TRIZ), ergonomic principles, and universal design to develop the foot-operated mechanism, while using Importance–Performance Analysis (IPA) and the Kano model to evaluate user satisfaction and identify design improvements. The foot-operated mechanism developed in this study features internal and external pedals for seamless door operation, a secure locking system, and color-coded indicators for clear occupancy status communication, ensuring both ease of use and privacy. The design significantly enhances hygiene by minimizing manual contact and improves user convenience, as confirmed through the IPA-Kano analysis. This mechanism not only provides a practical and effective solution to contamination risks but also demonstrates versatility, making it suitable for various public spaces and accessible to a wide range of users. This study represents a significant contribution to public infrastructure by providing a safer, more hygienic, and sustainable solution for door operation in public spaces. Full article

Aiming at the problems of low soil cover and serious wear and tear of transmission parts in the soil lifting device of potato planters, this paper carries out innovative optimization design of its key parts based on TRIZ theory. The discrete element model of the soil model and the multi-body dynamic model of the soil lifting device are established, the upper scraping and lower scraping soil lifting devices are simulated respectively through the method of DEM-MBD coupling, and the working mechanism of the soil lifting device is further explored. The simulation results show that the lower scraping type lifting device has a large conveying capacity and a stable flow rate at the soil outlet. The results of the soil tank performance comparison test show that: the improved soil lifting device has a simple structure, large conveying capacity, stable flow rate, and fast flow speed and is not easily congested. It meets the standard requirements of dryland potato seedling strip mulching planting technology on mulching parameters and is of great significance for improving dryland food production on the Loess Plateau.

This study explored the relationship between lean management, carbon inventory, and carbon reduction, along with the main factors affecting factory carbon inventory and carbon reduction, and proposed a set of carbon emission reduction strategies based on green value stream mapping. An electroplating factory and its production line in Taiwan was selected. Fourteen carbon inventory records, three work circle meetings, and green value flowcharts were utilized to collect and analyze data. Furthermore, this study applied the DMAIC framework and TRIZ to solve the issue of carbon emissions. The key factor affecting factory carbon inventory and carbon reduction was found to be electricity waste, which could be reduced through energy-saving methods. After analyzing the green value stream mapping, effective carbon emission reduction can be implemented in the manufacturing process. The company was found to gradually progress towards carbon reduction after investigating seven major green wastes. This study confirms that lean management can help organizations achieve their carbon emission reduction goals and is valuable in improving the organization’s environmental performance and competitiveness.

In order to effectively curb the rapid growth trend in Spartina alterniflora in coastal cities of China, this study proposes an innovative mechanical equipment design scheme for eradicating Spartina alterniflora. Based on literature analysis and field research, the AHP (analytic hierarchy process) model is constructed to quantify and prioritize the diverse needs of users for control equipment. Subsequently, the House of Quality (HOQ) in QFD (Quality Function Deployment) is used to analyze the key components and structure of the equipment to ensure its performance and feasibility in practical applications. Finally, combined with the Theory of Inventive Problem Solving (TRIZ), the potential problems encountered in the structural design of the equipment are analyzed, and the corresponding creative principles are applied to solve the contradictions and complete the optimal scheme design. This study, via the acquisition of user needs and further analysis of the machinery’s structure, proposes a scheme that can address many problems related to Spartina alterniflora in China and provide new technical ideas for the field of wetland environmental protection.

Camellia oleifera fruit pickers are essential for improving picking efficiency and promoting the Camellia oleifera industry. However, it is challenging to develop pickers that meet user needs. Current design tools and methods have limitations, such as a single model, poor synergy between integrated models, and subjective bias when analysing user requirements and translating them into product attributes. To solve these problems, this study proposes a new design decision model based on the Fuzzy Analytic Hierarchy Process (FAHP), Function Analysis System Technique (FAST), Theory of Inventive Problem Solving (TRIZ Theory), and extension transformation theory. The model was developed and applied to design an Camellia oleifera fruit picker. In this paper, an empirical investigation of an Camellia oleifera base in Wuhan was carried out, and multi-level demand analysis was used to identify the design demands in the behavioural process; FAHP was used to calculate the demand weights to clarify the design focus; expert knowledge was used to convert the demands into specific product functional features, and FAST was used to decompose these features to find the contradictory conflicts; TRIZ theory was used to determine the principles of resolving the contradictions, and the extension transformation theory were used to generate the creative design solutions for the products. By integrating FAHP, FAST, TRIZ theory and the extension transformation theory, the subjective bias in product design is eliminated, the design decision-making process is improved, and new methods and ideas are provided for the design of oleaginous tea fruit pickers and similar products. Finally, the conceptual design of an Camellia oleifera fruit picking machine was produced. However, the conceptual design has yet to be subjected to exhaustive simulation experiments and prototype testing. Future research will focus on conducting the necessary simulations, prototypes, and field tests to fully assess the feasibility and effectiveness of the design and make the required iterative improvements accordingly to commercialize the product eventually.

This study explored an innovative design of a drain cover for dirt removal, deodorization, and pest control. The research methods used in this study included an analysis of the literature, the TRIZ method and general design, and application of human factors engineering. Firstly, the contradiction matrix of the TRIZ method was used to find out the corresponding principles of invention for analysis. Based on the reference of the most innovative design, a drainage cover with rapid cleansing, deodorization, insect-repellent properties, and quick return was designed, and universal design was used to make the drainage cover. The innovative design can be more widely used to allow users to interact with the environment and products more harmoniously, and the innovative design of the drainage cover was faster and more hygienic through the human–computer interaction in the project. Additionally, the design was validated through analyses using the IPA and Kano models, confirming that it met the users’ requirements and expectations. The prototype’s structure was drawn by Autodesk Inventor drawing software (2024). The research results are as follows. We designed a sliding groove and the sliding block on the drainage cover so that the drainage cover could achieve the effect of rapid cleansing by sliding the sliding block. In terms of the odor control and pest prevention, we designed the odor-resistant block and the water filter under the drain cover so that the odor below the drain would not float upwards. And the pests in the drain hole cannot climb out. In terms of the improved operational design, the sliding block could be quickly returned and the use of the pushing aid to not touch the dirt. The successful development of the product validated the effectiveness of this research method for innovative product design and suggests its applicability for the development of other products.

Fiber SPR biosensors have low sensitivity and accuracy in detecting biomolecules. In this study, the TRIZ is applied to molecules and optimization. By defining the prototype system, clarifying the components and interacting objects, and adopting a functional model analysis and causal analysis, we deeply explored the key points and root causes of leakage and used a variety of tools, such as technological contradiction, object-field analysis, the HOW-TO model and knowledge effect library, physical contradiction, and the villain method, to come up with different solutions. A novel multimode–single-mode–multimode fiber SPR sensor based on the structure of gold (Au)–molybdenum disulfide (MoS2)–gold nanoparticles was designed and manufactured by using the TRIZ systematically for the first time. Under the effective guidance of the TRIZ, the sensitivity of the novel sensor is significantly enhanced after the optimization and experimental verification. The new sensor provides an effective reduction in the cost of detection and production and at the same time has excellent stability, ease of preparation, and high reproducibility, which is of significant value and significance for practical applications.
