“…Unlike the above methods using functional representations for analogy search, some structured analogical design methods take schematization concepts directly as analogical stimuli or use the schematization concepts to organize instance knowledge as the source for analogy search. TRIZ is such a structured method for analogical design that abstracts problem into some contradictions 15 and then develops solutions using the 40 inventive principles as conceptual analogies. 16 Inspiration from instance knowledge/analogies is also quite important in transforming the schematization solutions in TRIZ into specific solutions.…”

“…As a problem-solving principle or procedure extracted from design cases, expert schema can either be used to arouse innovation by solving design problems or contradictions, or work as the descriptive medium to associate more other cases to be used for analogy search. Abstracted from a great number of patents, the inventive principles in TRIZ (the Russian acronym for theory of inventive problem solving) are the typical expert schemas which could not only solve innovative design problems 15,16 but also associate instance analogies. 17,18 3.…”

By the knowledge transferring in different areas, analogical design has been considered as a powerful approach to promote the generation of novel ideas in product conceptual design. An efficient representation scheme for design knowledge is vital to implement analogical transferring. In this article, inspired from the structure mapping mechanism of analogical reasoning, a structure mapping–based representation was proposed to support designers to search and use design analogies. This representation can provide designers with insights into the structural information of knowledge situations, and consequently designers are able to implement the corresponding design analogy search at the level of the structural similarity, rather than the functional or superficial similarity. Based on this new representation scheme, a structure mapping–based analogical design framework was developed. In this framework, patents are used as the source of analogical knowledge, and the relational structure–based representation for the patent knowledge is created using the advanced natural language processing tools/algorithms. Next, the search of design analogies is implemented by means of the vector space model, and a new structure mapping–based concept generation model can finally guide the designers to use design analogies. An industrial case and a compared experiment were carried out to verify the feasibility and effectiveness of the proposed framework.

“…The TRIZ innovative design method was developed in the former Soviet Union by Altshuller, who had analyzed over 400,000 patents to establish 39 engineering parameters (Table 1), there are 40 inventive principles (Table 2) and contradiction matrix (Table 3). [14][15][16][17] It is effective to help designers to solve contradiction of system problems and to improve product design through using TRIZ method. During the problem-solving mode (Figure 1), the first step is to find the contradictory characteristics in product's system.…”

This article mainly proposes a design process in which a combination of brainstorming and the theory of inventive problem-solving, better known as TRIZ, are used in the design process. We used illustrations by designing a recycling machine for Tetra Pak. Designers are guided to apply brainstorming to come up with innovative designs and features utilizing 39 engineering parameters, a contradiction matrix, and 40 inventive principles for solving design problems. Once copyright and patent laws have been adhered in order to ensure there are no infringements, a prototype may be constructed, and patents may be applied for.

Quality function deployment is a cross-functional decision-making tool that converts customer needs into technical attributes of new products. Fuzzy numbers are usually adopted to evaluate the customer need importance and the customer need–technical attribute relationships. However, the weighted normalized customer need–technical attribute relationship matrix is not always full rank. If the different fuzzy numbers of two technical attributes are defined as the fuzzy negative ideal solutions, both the closeness coefficients are 0, and the traditional technique for order preference by similarity to an ideal solution cannot prioritize the two technical attributes. Actually, the rankings of different fuzzy numbers are not identical. To solve this problem, we present a new technique for order preference by similarity to an ideal solution to prioritize technical attributes in the fuzzy quality function deployment. The fuzzy positive ideal solution, fuzzy negative ideal solution, and distance measurement of the new technique for order preference by similarity to an ideal solution are improved. As a result, the proposed method not only prioritizes various forms of numbers without considering the lower and upper limits, the median, and boundary interval but also deals with the nonfull rank matrix. Besides, the Theory of Inventive Problem Solving is used to solve technical conflicts which are identified by the line-fitting method. The prioritization results from the proposed method can help to reasonably allocate design and manufacturing resources. Finally, a case on phone shell is given to illustrate the application of the proposed quality function deployment method.
