“…The most well-known and used design tools offered by TRIZ are the 40 principles, the trends of evolution, the contradiction matrix, and trimming. These tools have been used successfully in a wide range of industries, including aerospace, automotive, and manufacturing [15][16][17][18]. The 40 principles are based on the analysis of a large number of patents and ideas.…”

The growing demand for innovative and user-centric product design has led to a growing need for effective idea generation methods. In recent years, natural language processing (NLP) tools such as ChatGPT have emerged as a promising solution for supporting idea generation in various domains. This paper investigates a framework for studying the role of ChatGPT in facilitating the ideation process in product design. This investigation measures the impact of ChatGPT on the generation of innovative concepts compared to the use of “classic” design methods. An overview of the state-of-the-art idea generation methods in product design opens the paper. Then, the paper highlights some hypotheses about the impact of ChatGPT on innovative product design, aiming for product augmentation by adding features. The paper then describes the design experience in which ChatGPT is used as a tool for concept generation. Finally, the paper analyzes the dataset, using precise metrics to characterize the participants’ performance and compare them. This analysis allows the paper to argue about the validation/rejection of the hypotheses. The paper concludes with a discussion of the implications of the findings and some suggestions for future research. Along with the paper, the Microsoft Excel workbook used to perform the data analysis is available to the readers to perform their own data collection and analysis. The workbook UX has been carefully studied and developed to make it usable by anyone. At the same time, it should be flexible enough to manage several situations characterized by different numbers of participants, product functions to implement, and generated concepts.

“…When making statistics on the technical demands of ambulances, although a total of 5 groups of contradictions were found, the relative weight of the technical requirements involved in the contradictions and conficts is relatively low, which cannot attract high attention from users. It is not a pain point of traditional ambulances, and there is no need to discuss it specifcally [29]. Te conficts and solutions of the frst four groups of contradictions should be focused on, as shown in Table 11.…”

In recent years, with the sharp rise in the number of vehicles in China, traffic congestion is becoming increasingly serious, affecting the rapid passage of ambulances. In addition, it is common that vehicles are generally parked indiscriminately in some old communities, which also hinders ambulances into residential areas and reduces rescue efficiency. Apart from external factors, the root cause is that existing ambulances are too large to easily pass narrow roads. Besides, there are problems such as frequent empty runs and serious homogenization in traditional ambulances. Therefore, it is necessary to improve the design of traditional large ambulances. First, the user needs of different users for ambulances were determined through questionnaires and user interviews; then, the need judgment matrix of ambulances was constructed by using the analytic hierarchy process to rank user needs by weight, so as to determine the direction for new type ambulance design. Through quality function deployment, the user’s demands were transformed into the technical demands of ambulances, and the conflicts were found. Meanwhile, top-ranked needs were analyzed by using theory of inventive problem solving to seek the corresponding feasible solutions quickly, and innovative design of ambulances was conducted on this basis. However, many designers have not considered the product validation link when using these three methods for innovative design. On the contrary, in this improved ambulance design, the FCE is introduced to score the new design, find the deficiencies, and improve them, thus completing the missing link in the traditional design and forming a complete set of scientific design process. The traditional large ambulance with standard length, width, and height of 5,800 mm, 2,000 mm, and 2,600 mm is modified into a mini-ambulance with length, width, and height of 3,500 mm, 1,600 mm, and 2,250 mm. Simultaneously, various details are optimized to design a community micro-ambulance that truly meets the needs of users and enhances user satisfaction. Quantifying and ranking users’ various functional needs for ambulances by using the AHP/QFD/TRIZ theory and providing corresponding feasible solutions have identified the breakthrough direction for the research on innovative design of community ambulances and have also provided references for the design of other products.

BackgroundWith the accelerating trend of global aging, over one billion people need to use one or more types of assistive products. However, the high abandonment rate of current assistive products is affecting the quality of life of the older adults, posing challenges to public health. Accurately capturing the preference factors of the older adults in the design process is an important way to improve the acceptance of assistive products. In addition, a systematic approach is needed to translate these preference factors into innovative product solutions. These two issues are less addressed in existing research.MethodsFirst, the evaluation grid method was used to conduct in-depth interviews with users and extract the structure of preference factors for assistive products. Quantification theory type I was used to calculate the weight of each factor. Secondly, universal design principles, TRIZ theory's contradiction analysis techniques, and invention principles were used to translate the preference factors into design guidelines. Then, finite structure method (FSM), morphological chart, and CAD techniques were used to visualize the design guidelines as alternatives. Finally, Analytic Hierarchy Process (AHP) was used to evaluate and rank the alternatives.ResultsA Preference-based Assistive Product Design Model (PAPDM) was proposed. The model includes three stages: definition, ideation, and evaluation. A case study on walking aid demonstrated the execution of PAPDM. The results show that 28 preference factors influence the four psychological needs of the older adults: sense of security, sense of independence, self-esteem, and sense of participation. These psychological needs were reflected in the shape, color, material, universality, user-friendly, reliability, and smart functions of assistive products. The preference factors were transformed into five design guidelines, and three alternatives were generated. Finally, the evaluation concludes that solution C was the optimal solution.ConclusionThe PAPDM framework provides designers with a transparent, progressive approach to designing assistive products that meet unique needs and preferences of older adults. This enhances objectivity and scientific rigor in assistive product development, avoiding blind design and production. By considering the perspective of older adults from the outset, we can avoid high abandonment rates of assistive products and contribute to promoting active aging.
