Design decisions occur in all phases of product design and largely affect the merits of the final solution, which will ultimately determine the success or failure of the product in the market. Product design is a continuous process, and a large number of existing studies have proposed decision methods and decision indicators for the characteristics of different stages of design. These methods and indicators can meet the requirements of one of the phases: demand analysis, conceptual design, or detailed design. However, further research can still be conducted on the integration of methods throughout the design phase, using intelligent design methods, and improving the design continuity and efficiency. To address this problem, a TOPSIS-MOGA-based multi-indicators decision model for product design solutions is proposed, including its product design process, decision algorithm, and selection method. First, a TOPSIS-MOGA integrated model for conceptual design and detailed design process is established, the continuity of decision-making methods is achieved by integrating decision indicators. Second, conceptual design solutions are selected through the technique for order of preference by similarity to ideal solution (TOPSIS), based on hesitant fuzzy linguistic term sets and entropy weight method. Finally, detailed design solutions are selected through a multiobjective genetic algorithm (MOGA), based on a polynomial-based response surface model and central combination experimental design method. A case study of the decision-making in the design of high-voltage electric power fittings is presented, the conceptual design phase and the detailed design phase are connected through the indicators, which demonstrates that the proposed approach is helpful in the decision-making of the product design solutions.

“…This not only simplifies the problem but also provides a clearer view of expected results from the query. There are vast selections of problem analysis tools such as Causal Loop diagram [8] that identify the polarity influences, Functional Decomposition and Morphology [9] decompose complex systems and re-merges as well as Systems Dynamics [10] that can simulate potential design changes. However, a simple and direct tool should be selected as it can provide more direct input for the model to manipulate.…”

Conceptual design represents a critical initial design stage that involves both technical and creative thinking to develop and derive concept solutions to meet design requirements. TRIZ Scientific Effects (TRIZSE) is one of the TRIZ tools that utilize a database on functional, transformation, parameterization of scientific effects to provide conceptual solutions to engineering and design problems. Although TRIZSE has been introduced to help engineers solve design problems in the conceptual design phase, the current TRIZSE database presents general scientific concept solutions with a few examples of solutions from patents which are very abstract and not updated since its introduction. This research work explores the derivation of a novel framework that integrates TRIZ scientific effects to the current patent information (USPTO) using data mining techniques to develop a better design support tool to assist engineers in deriving innovative design concept solutions. This novel framework will provide better, updated, relevant and specific examples of conceptual design ideas from patents to engineers. The research used Python as the base programming platform to develop a conceptual design software prototype based on this new framework where both the TRIZSE Database and Patents Database (USPTO) are searched and processed in order to build a Doc2Vec similarity model. A case study on the corrosion of copper pipelines by seawater is presented to validate this novel framework and results of the novel TRIZSE Database and patents examples are presented and further discussed in this paper. The results of the case study indicated that the Doc2Vec model is able to perform its intended similarity queries. The patent examples from results of the case study warrant further consideration in conceptual design activities.

“…Conceptual design has the concept of providing detailed information on the concept of a design [22]. Its design concept interprets the inventive principle of TRIZ [23], which can provide an effective solution by identifying user behavior or physical factors [24]. Walker's conceptual design dimensions will use anthropometric data of children with cerebral palsy as a reference.…”

Children with cerebral palsy at rehabilitation centers had difficulty performing walking rehabilitation with the existing walker. The resulted in children with cerebral palsy feeling dissatisfied with existing walkers, and this dissatisfaction resulted in their interest in ongoing rehabilitation. The existing walker does not accommodate the needs of cerebral palsy children, resulting in lousy form and dissatisfaction when using a walker for rehabilitation and reduce their interest in rehabilitation. Therefore it is necessary to redesign the walker to prevent bad form and increase the satisfaction level of children with cerebral palsy. The QUEST 2.0 questionnaire was used as a reference for designing. Based on the dimensions from the QUEST 2.0 questionnaire, the walker design criteria were determined. Then use the TRIZ method to resolve any technical contradictions that occur at the design stage. Assistive device
