With the evolution of the surrounding world market, engineers have to propose innovations in products and processes. Industrial innovation frequently results from an improved understanding of basic physics. In this paper, an approach to accelerate inventive preliminary design is presented. This method combines the main advantages of CBR (Case Based Reasoning) and TRIZ (Russian acronym for Theor...

Systems engineering frequently includes efforts to reduce part count with the goal of cutting costs, enhancing performance, or improving reliability. This paper examines the engineering practices related to part count, applying three different theories -the Theory of Inventive Problem Solving, Axiomatic Design, and Highly Optimized Tolerance. Case studies from the jet engine industry are used t...

New Normal becomes the way out to keep Indonesia's weakened economy because of covid-19 pandemic stays in balance. Of course, must be well-balanced with application strict protocols reduce transmission rates and anticipate a surge new cases. From few points protocols, using face mask is considered as most-effective basic need. Re-designing aiming at eliminating worsening feature developing impr...

Different kinds of problem solving methods exist for different kinds of problems. One can recognize two kinds of problems: optimization ones, for which a solution can be found by adjustment of the value of problem parameters; and inventive problems, for which no solution is known. This problem insolvability can be due to the lack of a “good” solving algorithm or to a non adequate problem repres...

To improve the existing mechanism for opening the car-door of a mobile shop vehicle, we first apply the contradiction matrix and the idealized design technique of the Theory of the Solution of Inventive Problems (TRIZ) as a reference to ameliorate an automatic car-door opening (closing) system, and find a scheme matching requirements in design. Next, a motor gear transmission system is designed...
