Reduction of environmental impact and energy consumption becomes a crucial issue. In the field of product manufacturing, development and improvement of products that reduce environmental impacts are called the design for environment (DfE). This paper proposes a systematic methodology of the DfE through identification and resolution of contradictions based on the concept of TRIZ (Teoriya Resheni...

Product technology maturity foresting is vital for any enterprises to hold the chance for innovation and keep competitive for a long term. The Theory of Invention Problem Solving (TRIZ) is acknowledged both as a systematic methodology for innovation and a powerful tool for technology forecasting. Based on TRIZ, the state -of-the-art on the technology maturity of product and the limits of applic...

The capability of anticipating the main features of future products and related manufacturing processes is more and more a critical asset in industry, due to the innovation-based competition of markets and to the extremely reduced lead time of modern product development cycles. The paper presents a survey of TRIZ, the Theory of Inventive Problem Solving, as a reference methodology to support de...

Firstly, in order to overcome the shortcoming of using only AD or TRIZ solely,and solve the problems currently existed in weapon equipment requirement demonstration, the paper construct the method system of weapon equipment requirement demonstration combining QFD ,AD,TRIZ,FA . Then, we construct a CAI model frame of weapon equipment requirement demonstration, which include requirement decompose...

Functional design is a process includes function understanding, function recognition, function representation, function modeling and functionto-structure mapping. The effect in TRIZ is extended by multi-pole effect model and effect chain modes, and then the functions and flows in TRIZ are reclassified. The combinative relationships among functions are discussed, and the function modeling based ...

To make artificial knee joints have lower long-term wear rate, a new method for reformed design of sagittal femoral condylar geometry based on TRIZ (Theory of Inventive Problem Solving) was proposed. Firstly, according to the development history of sagittal femoral condylar geometry and evolution theory of TRIZ, future state of the evolution line of femoral condylar geometry in sagittal plane w...
