“…Its effectiveness in idea generation has also been demonstrated in classroom settings [10,11]. Despite its success in aiding idea generation, however, TRIZ (implemented alone) falls short in selecting the most appropriate idea, and hence, using it in unison with appropriate tools is recommended.…”

In this paper, we present a method incorporating axiomatic design, TRIZ, and mixed integer programming (MIP) to solve engineering design problems. Axiomatic design decomposes the problem into several mutually independent sub-problems, TRIZ generates all feasible design concepts, and MIP optimizes cost and the numerical configuration among available design options. The method is illustrated on a locomotive ballast arrangement case study. Ballast arrangement is a key process for a locomotive assembly, which determines the carrying capacity. Due to the unsophisticated technology requirements, the ballast arrangement process has received little attention. The trend of mass customization, however, demands locomotive manufacturers to provide diverse products with affordable cost and reduced time. Thus, a flexible and easy to implement ballast arrangement process design is sought. The proposed method determines what material combinations, in what quantity, and where in the limited cavities should the ballast be allocated to minimize cost. Using the case study, we demonstrate the advantages in cost reduction and time savings. The synergy of these improvements not only can enhance productivity and agility but also competitive advantage.

“…TRIZ, the Russian acronym for "Theory of Inventive Problem Solving" has been shown to significantly increase the number of unique solutions compared to traditional methods such as brainstorming (Okudan et al, 2006). To develop TRIZ, Genrich Altshuller et al (Altshuller, 1988) studied over 1.5 million patents to identify 39 engineering parameters as commonly improved attributes in innovative designs.…”

The Proton Exchange Membrane (PEM) fuel cell is an attractive energy conversion device that can provide efficient and clean electrical energy. However, limitations in water management can deleteriously affect its conversion efficiency. Overcoming this technological challenge is essential. In this paper, two design methodologies, biomimetic design and TRIZ, were used to find potential solutions to this water management problem. Each design method produced two potential solutions. We found biomimetic design to have more potential for bias by the designer’s prior knowledge of biology. This bias can serve to either hinder or help the design process. A notable finding is that biomimetic design and TRIZ can be considered mutually inclusive in the potential solutions generated in this study. This suggests that either design method could have been used to produce the same solutions.

“…Research has shown that TRIZ has potential when used with brainstorming. For example, Okudan et al [1] compared the ideation effectiveness of TRIZ and brainstorming in comparison to only using brainstorming measured by three ideation metrics: quantity, variety, and novelty as described by Shah et al [2]. The design problem students solved was focused on air velocity control for fumehoods, and was presented by an industry sponsor.…”

Today, more than ever, we need engineering graduates equipped with effective design skills and a high degree of ideation competence. This paper presents results of our pilot study on improving the ideation performance of undergraduate engineers through training in TRIZ and emphasis on sketching. This is the first study of its type to rigorously test the value of TRIZ on ideation performance. Positive study findings would provide guidance to introductory and capstone design course instructors, as well industry practitioners who intend to enhance their ideation toolkits. Our objective is to test our hypotheses that TRIZ, or sketching emphasis improves design ideation alone or in combination. A series of classroom studies using investigatordeveloped interventions (modules) that train students in TRIZ and Sketching Importance is run. Class participants perform ideation exercises. The results of the ideation exercises are assessed and scored for Novelty, Variety and Quantity. In the paper, we document the results of the pilot experimentation. Overall, pilot studies will help fine tune the experimental approach.
