Lower Abstraction Level of TRIZ Inventive Principles Improves Ideation Productivity of Engineering Students

The 40 Altshuller Inventive Principles with numerous sub-principles remain over decades the most frequently applied tool of the Theory of Inventive Problem Solving TRIZ for systematic idea generation. However, their application often requires a concentrated, creative and abstract way of thinking that can be fairly challenging for the newcomers to TRIZ. This paper describes an approach to reduce the abstraction level of inventive sub-principles and presents the results of the idea generation experiment conducted with three groups of undergraduate and graduate students from different years of study in mechanical and process engineering. The students were asked to generate and to record their individual ideas for three design problems using a pre-defined set of classical and modified sub-principles within 10 minutes. The overall outcomes of the experiment support the assumption that the less abstract wording of the modified sub-principles leads to higher number of ideas. The distribution of ideas between the fields of MATCHEM-IBD (Mechanical, Acoustic, Thermal, Chemical, Electrical, Magnetic, Intermolecular, Biological and Data processing) differs significantly between groups using modified and abstract sub-principles

Magnetic modelling and magnetohydrodynamic simulations of an aluminium production electrolytic cell

A simulation of the motion of molten aluminium inside an electrolytic cell is presented. Since the driving term of the aluminium motion is the Lorentz (j × B) body force acting within the fluid,this problem involves the solution of the magneto-hydro-dynamic equations. Different solver modules for the magnetic field computation and for the fluid motion simulation are coupled together. The interactions of all these are presented and discussed

On the Efficiency of TRIZ Application for Process Intensification in Process Engineering

Part 4: TRIZ and FunctionsInternational audienceIn recent years, the application of TRIZ methodology in the process engineering has been found promising to develop comprehensive inventive solution concepts for process intensification (PI). However, the effectiveness of TRIZ for PI is not measured or estimated. The paper describes an approach to evaluate the efficiency of TRIZ application in process intensification by comparing six case studies in the field of chemical, pharmaceutical, ceramic, and mineral industries. In each case study, TRIZ workshops with the teams of researchers and engineers has been performed to analyze initial complex problem situation, to identify problems, to generate new ideas, and to create solution concepts. The analysis of the workshop outcomes estimates fulfilment of the PI-goals, impact of secondary problems, variety and efficiency of ideas and solution concepts. In addition to the observed positive effect of TRIZ application, the most effective inventive principles for process engineering have been identified

A Future Eco-Design Framework Based on TRIZ’s Contradictions and Bio-Inspired Design Process

International audienceIn the products development process, innovation is prescribed as a key parameter for technological evolution. It describes itself as a complex process that exploits different ways of transforming an idea into a reliable product. However, its way of resolution tends to amplify the conflicts of technical systems called technological contradictions. In this paper, was used the contradiction solving methods based on TRIZ Matrix in order to extract an ideal inventive principle which basically requires the existence of at least one contradiction to be eliminated. Then we will explore the potential of Bio-Inspired Design process that seeks, from ecosystem elements to extract conflicting functions that can be technologically transferable. Taking in account the aforementioned reasoning, we will discuss how the technical contradictions and their causalities can interrogate biomimetic databases to improve the innovation process by designing new environmental-friendly products that are more reliable. The aim of this work is to introduce new “eco-principles” by analyzing analogies between technical and biological solutions. The main objective is to analyze the possibilities to optimize an eco-inventive process for the next new technological generations. Based on this vision, the endpoint is to provide designers and engineers with the ideal eco-inventive methodology
