IPG as a new method to improve the agility of the initial analysis of the inventive design

Abstract

TRIZ method has long proven its value without appearing to the industrial world as inevitable. Design researchers have therefore addressed the limitations of the TRIZ method and have overcome them with more systematic approaches. Among these, the Inventive Design Method (IDM) has been the subject of several articles and put into practice in the industry. It is considered an improvement over TRIZ but still suffers from some drawbacks in terms of the time-consuming nature of its implementation. We focused on the IDM process by trying to both identify its areas of inefficiencies while attempting to preserve the quality of its deliverables. Our approach consists of applying the precepts of Lean to IDM. The result is the Inverse Problem Graph (IPG) method, inspired by IDM, but offering significant progress in reducing the time required to mobilize experts while preserving its inventive outcomes. This article outlines our approach for the construction of this new method.

Semantic TRIZ feasibility in technology development, innovation, and production: A systematic review

“…Nevertheless, the indicators for assessing these various types of networks are (1) centrality (closeness-centrality), (2) density, (3) cohesion index and (4) structural holes. Recently [ 121 ], proposed the inverse problem graph (IPG) method in which five types of problems were predefined from the initial analysis of the inventive design. This method was inspired by inventive design method (IDM).…”

Framework for evaluating solution concepts in TRIZ-based inventive designs using a functional, behavioral, and structural modeling approach

“…Thus, in the end, this study managed to narrow down the number of inventive design approaches shown in Figure 1 which have attracted the attention of researchers and organizations in the last two decades and are useful for generating SCs in the concept generation phase. Also, this study identified and focused on the inventive design approaches on which modern tools have been applied, like TRIZ and its extensions such as IDM, inverse problem graph (IPG) [10], etc.…”

Method to build a generalized table of parameters in engineering design of technical systems: Lattice structure as a case study

“…Design of Experiments (DoE) [16] is a very common and robust approach to modeling and representing the design parameters. Nevertheless, it still suffers from certain limitations.…”
