What is the alternative way to pump water that will not leak when a crack appears? If the pressure inside the pipe were less than outside there would be no leak. Use of a vacuum pump (i.e. atmospheric pressure is used to circulate the water) is a possible solution to the problem. 5 Positioning and further development As mentioned in the introduction many authors are now positioning TRIZ with QFD & Taguchi, as displayed in figure 6. QFD providing the integrated link with the customer needs and wants and Taguchi providing the rigor of engineering analysis to develop a robust design. TRIZ is helping to fill the void between the two in structuring the innovation process. The contradiction matrix in the roof of the QFD House of Quality provides a natural target zone for 74 Problem statement developments from the Furnace Functional Model 1. Find a way to eliminate, reduce or prevent [the] (Water Leak), under the condition of [the] (Burst pipe) and (Pressurised system). 2. Find an alternative way to obtain [the] (Pressurised system), that provides or enhances [the] (Circulate water), and does not cause [the] (Water Leak). 3. Find a way to enhance [the] (Pressurised system). 4. Find a way to resolve the contradiction: [the] (Pressurised system) should exist to obtain [the] (Circulate water), and should not exist in order to avoid [the] (Water Leak). 5. Find a way to do without [the] (Pressurised system) for obtaining [the] (Circulate water). 6. Find a way to eliminate, reduce or prevent [the] (Burst pipe). 7. Find an alternative way to obtain [the] (Circulate water), that provides or enhances [the] (Cools furnace walls), and does not require [the] (Pressurised system). (Extract from Ideation IWB Software)

TRIZ. However that assumes the customers wants can reflect the innovation yet to be offered to the market. A separate but parallel industrial development to TRIZ over the past 20 years is the Theory of Constraints (TOC), which is also an innovative problem solving tool, but in manufacturing/ business management. It is interesting to note the common interest in contradictions. In TOC the major tool for innovation is referred to as the Conflict Resolution Diagram and the effect-cause-effect cognitive mapping tools has similarities to TRIZ functional modelling. Work on integrating the underlying principles behind these two approaches is a developing research topic for the authors 8 (Mann & Stratton, 2000). 6 Teaching in practice Many engineering and product design curricula are acknowledging the need for innovation and trying to encourage creativity. TRIZ clearly complements the existing tools and techniques and has been developed to meet the specific needs of the engineering environment. It has been introduced to BEng university courses this year at Bath, Liverpool John Moores and to a lesser extent at Nottingham Trent. Early

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
