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] |
TRIZ
TRIZ (; ) is a methodology that combines an organized, systematic method of problem-solving with analysis and forecasting techniques derived from the study of patterns of invention in global patent literature. The development and improvement of products and technologies in accordance with TRIZ are guided by the laws of technical systems evolution. Its development, by Soviet inventor and science-fiction author Genrich Altshuller and his colleagues, began in 1946. In English, TRIZ is typically rendered as the theory of inventive problem solving. TRIZ developed from a foundation of research into hundreds of thousands of inventions in many fields to produce an approach which defines patterns in inventive solutions and the characteristics of the problems these inventions have overcome. The research has produced three findings: # Problems and solutions are repeated across industries and sciences. # Patterns of technical evolution are replicated in industries and sciences. # The inn ...

Contradiction Matrix Of TRIZ Method 360dpi
In traditional logic, a contradiction involves a proposition conflicting either with itself or established fact. It is often used as a tool to detect disingenuous beliefs and bias. Illustrating a general tendency in applied logic, Aristotle's law of noncontradiction states that "It is impossible that the same thing can at the same time both belong and not belong to the same object and in the same respect." In modern formal logic and type theory, the term is mainly used instead for a ''single'' proposition, often denoted by the falsum symbol \bot; a proposition is a contradiction if false can be derived from it, using the rules of the logic. It is a proposition that is unconditionally false (i.e., a self-contradictory proposition). This can be generalized to a collection of propositions, which is then said to "contain" a contradiction. History By creation of a paradox, Plato's '' Euthydemus'' dialogue demonstrates the need for the notion of ''contradiction''. In the ensuing d ...

Parameter
A parameter (), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its performance, status, condition, etc. ''Parameter'' has more specific meanings within various disciplines, including mathematics, computer programming, engineering, statistics, logic, linguistics, and electronic musical composition. In addition to its technical uses, there are also extended uses, especially in non-scientific contexts, where it is used to mean defining characteristics or boundaries, as in the phrases 'test parameters' or 'game play parameters'. Modelization When a system theory, system is modeled by equations, the values that describe the system are called ''parameters''. For example, in mechanics, the masses, the dimensions and shapes (for solid bodies), the densities and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Tolerance
Engineering tolerance is the permissible limit or limits of variation in: # a physical dimension; # a measured value or physical property of a material, manufactured object, system, or service; # other measured values (such as temperature, humidity, etc.); # in engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or boat under a bridge as well as a train in a tunnel (see structure gauge and loading gauge); # in mechanical engineering, the space between a bolt and a nut or a hole, etc. Dimensions, properties, or conditions may have some variation without significantly affecting functioning of systems, machines, structures, etc. A variation beyond the tolerance (for example, a temperature that is too hot or too cold) is said to be noncompliant, rejected, or exceeding the tolerance. Considerations when setting tolerances A primary concern is to determine how wide the tolerances may be without affecting other factors or the outcome of a ...

Genrich Altshuller
Genrikh Saulovich Altshuller (, ; 15 October 1926 – 24 September 1998) was a Soviet engineer, inventor, and writer. He is most notable for creating the TRIZ, Theory of Inventive Problem Solving, better known by its Russian acronym TRIZ. He founded the Azerbaijan Public Institute for Inventive Creation and was the first President of the TRIZ Association. He also wrote science fiction under the penname Genrikh Altov. Early life Altshuller was born in Tashkent, Uzbekistan (formerly the USSR) to a family of journalists of Jewish background. He moved with his family to Baku, Azerbaijan, where he spent most of his life. After graduating from high school he was admitted to the Azerbaijan Industrial Institute. Altshuller enlisted in the Army in 1944 and was trained as a fighter pilot but did not see action. He joined the Soviet Navy at the age of twenty and attracted attention for his ability to fix engines, getting assigned to the Commission of Innovation of the Capian Navy Flotilla. ...

Laws Of Technical Systems Evolution
The laws of technical systems evolution are the most general evolution trends for technical systems discovered by TRIZ author G. S. Altshuller after reviewing thousands USSR invention authorship certificates and foreign patent abstracts. Altshuller studied the way technical systems have been invented, developed and improved over time. He discovered several evolutionary trends that help engineers to anticipate improvements that are most likely to make it advantageous. Convergence to ideality is the most important of these laws. There are two concepts of ideality: ideality as a leading pathway of a technical system's evolution, and ideality as a synonym of "ideal final result", which is one of the basic TRIZ concepts. History Studying paths of evolution of technical systems has been a primary research method of TRIZ since its inception. But until the 1970s the discovered recurrent patterns of evolution were not consolidated into a separate section of TRIZ and were scattered among ...
