Contradiction Matrix
The 40 principles of invention are a suite of ideas that purport to aid in solving hard technical problems. The principles are based on TRIZ, a theory about problem solving. They are used together with contradiction matrix, contradiction matrices. Contradiction matrix A contradiction matrix is a structured and systematic representation of basic engineering parameters of objects, or systems, such as mass, length and Engineering tolerance, manufacturing tolerances. TRIZ TRIZ claims that by studying an individual parameter that is causing a problem (e.g., the mass of an object needs to be reduced), and the other parameters with which it conflicts (e.g., the lower mass would require thinner material, which is more likely to undergo catastrophic failure), solutions can be created. This is actually the simplification of some fact. Namely, the structured contents of each of the cells within the contradiction matrix, (i.e. cells fulfilled with ordered principles and identified b ...

40 Principles Of TRIZ Method 960dpi
4 (four) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is tetraphobia, considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga Empire, Shunga would add a horizontal line on top of the digit, and the Northern Satraps, Kshatrapa and Pallava dynasty, Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, endi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
