INTRODUCTION TO TRIZ :
TRIZ is a theory created to systematize processes and procedures related to innovation and creativity in solving problems.
It is a Russian acronym expressed in English as ‘Theory for the Solution of Inventive Problems. A theory, operating procedures, and tools compose TRIZ. Genrich Saulovich Altshuller (1926-1998) invented TRIZ in 1946. TRIZ will capture the creative process in technical and technological contexts by codifying and making the creative process repeatable and applicable. In short, TRIZ is a proper theory of invention.
The inventing capability is usually deemed as a natural quality. It is not a systematized process with a scientific approach. Altshuller disagreed with the idea. Then, he started from the study of patented ideas to come up with the deduction of the general principles governing the evolution of technical systems underpinning the formulated theory of invention.
TRIZ allows the analysis, structuring of models, and getting problem solutions with a systematic approach based upon subsequent stages and operating tools. Currently, the TRIZ methodology has proved to be the most efficient to solve inventive problems and one which may be learned and used without any need for innate individual creativity.
Supporting the validity of the methodology is the diffusion in companies both in small and medium enterprises, as well as in several giants at a worldwide level, such as 3M, BAE Systems, Boeing Corporation, Daimler Chrysler, Dow Chemical, Ford, GM, HP, Hitachi, IBM, Intel, Johnson & Johnson, LG Electronics, Motorola, Kodak, NASA, Nestlé, OTIS Elevators, Panasonic, Procter & Gamble, Samsung, Siemens, Toyota, UNISYS, Xerox, Whirlpool, Saipem and BTicino.
STRUCTURED PROBLEM-SOLVING APPROACHES :
provide a step-by-step process to define a problem, analyze the current situation, identify possible causes, develop solutions, discuss ways to implement solutions, standardize the solution and monitor the progress.
FUNCTIONAL ANALYSIS :
People buy functions/functionality and not products. Understanding function and functionality at the most basic level is fundamental to the successful application of TRIZ. Solutions change, functions stay the same. Knowledge classification by function allows ready access to other solutions.
CAUSE AND EFFECT CHAIN ANALYSIS :
A tool to refine a problem statement and drill down to find the root cause of the problem.
Typical engineers would add components to a system to enhance or solve a problem. After analyzing the system’s function and understanding the root cause, they eliminate unnecessary components for the main function. The purpose is to search for an ideal system that is less costly and has fewer components.
Each system evolves toward its ideal state. The ideal system state exists when the system gains all benefits with no harmful things and no costs. It provides better, faster, low cost, low error, and low maintenance. The ideal system consists of all positives and no negatives. It is a system that does not materially exist while its functions are achieved. The ideal system is no system. In the absolute sense, ideality is unachievable, but in a relative sense, it is achievable.
ENGINEERING CONTRADICTION :
An engineering contradiction is a situation in which an attempt to improve one parameter of a system leads to the worsening (impairment) of another parameter. It can be reflected in a positive and negative interaction between two or more components.
39 PARAMETERS :
System parameter is defined as any factor that defines a system and determines (or limits) its performance. The parameter typically describes the characteristics of a system. Thirty-nine parameters typically set the characteristic of most systems.
The inventive principle is a basic generalized rule accepted as fact. Works are consistently followed as a basis of reasoning or explanation of the invention. Altshuller screened 200,000 patents to find resolved contradictions from each invention and how it achieved it. He synthesized down to 40,000 patents. Finally, he developed a set of 40 inventive principles.
CONTRADICTION MATRIX :
Contradiction Matrix is a systematic method of solving engineering contradictions without trade-off solutions. The user identifies improving and worsening features of the engineering system.
