TRIZ Knowledge Base
TRIZ (; russian: теория решения изобретательских задач, ', lit. "theory of inventive problem solving") is “the next evolutionary step in creating an organized and systematic approach to problem solving. The development and improvement of products and technologies according to TRIZ are guided by the objective Laws of Engineering System Evolution. TRIZ Problem Solving Tools and Methods are based on them.” In another description, TRIZ is "a problem-solving, analysis and forecasting tool derived from the study of patterns of invention in the global patent literature". It was developed by the Soviet inventor and science-fiction author Genrich Altshuller (1926-1998) and his colleagues, beginning in 1946. In English the name is typically rendered as the theory of inventive problem solving, and occasionally goes by the English acronym TIPS. Following Altshuller's insight, the theory developed on a foundation of extensive research covering hundreds of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genrich Altshuller
Genrikh Saulovich Altshuller (Ге́нрих Сау́лович Альтшу́ллер, ) (born Tashkent, Uzbek SSR, USSR, 15 October 1926; died Petrozavodsk, Russia, 24 September 1998), was a Soviet engineer, inventor, and writer. He is most notable for the creation of the Theory of Inventive Problem Solving, better known by its Russia 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 pen-name Genrikh Altov. Early life Working as a clerk in a patent office, Altshuller embarked on finding some generic rules that would explain creation of new, inventive, patentable ideas. He eventually created the ''Teoriya Resheniya Izobreatatelskikh Zadach'' (Theory of Inventive Problem Solving or TRIZ)). Arrest and imprisonment During Joseph Stalin's political purges of members of the Communist Party in 1950, he was imprisoned for political reasons and continued his s ...

Khrushchev Thaw
The Khrushchev Thaw ( rus, хрущёвская о́ттепель, r=khrushchovskaya ottepel, p=xrʊˈɕːɵfskəjə ˈotʲ:ɪpʲɪlʲ or simply ''ottepel'')William Taubman, Khrushchev: The Man and His Era, London: Free Press, 2004 is the period from the mid-1950s to the mid-1960s when Political repression in the Soviet Union, repression and Censorship in the Soviet Union, censorship in the Soviet Union were relaxed due to Nikita Khrushchev's policies of de-Stalinization and peaceful coexistence with other nations. The term was coined after Ilya Ehrenburg's 1954 novel ''The Thaw (Ehrenburg novel), The Thaw ''("Оттепель"), sensational for its time. The Thaw became possible after the Death and state funeral of Joseph Stalin, death of Joseph Stalin in 1953. General Secretary of the Communist Party of the Soviet Union, First Secretary Khrushchev denounced former General Secretary Stalin in the On the Cult of Personality and Its Consequences, "Secret Speech" at the 20th Congres ...

Level Of Invention
Level of invention (or ''degree of inventiveness'', or ''level of solution'', or ''rank of solution'', or ''rank of invention'') is a comparative, relative degree of changes to the previous system (or solution) in the result of solution of inventive problem (one containing a contradiction). Term was defined and introduced by TRIZ author G. S. Altshuller. After initially reviewing 200,000 patent abstracts, Altshuller selected 40,000 as representatives of high level inventive solutions. The remainder involved direct improvements easily recognized within the specialty of the system. Altshuller separated the patents' different degrees of Inventive step and non-obviousness, inventiveness into five levels: * Level 1 – Routine design problems solved by methods well known within the specialty. Usually no invention needed. :example: use of coal for writing * Level 2 – Minor improvements to an existing system using methods known within the industry. :example: graphite pencil (wrappe ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40 Principles Of TRIZ Method 720dpi
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

Contradictions Matrix Image
In traditional logic, a contradiction occurs when a proposition conflicts 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 ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 TRIZ (; russian: теория решения изобретательских задач, ', lit.

40 Principles Of Invention
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 Matrices. Contradiction matrix A Contradiction Matrix is a structured and systematic representation of basic engineering 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 ...s of objects, or systems, such as weight, length and manufacturing tolerances. TRIZ TRIZ claims that by studying an individual parameter that is causing a problem (e.g., the weight of an object needs to be reduced), and the other parameters with which it conflicts (e.g., the lower weight would require thinner material, which is more likely to undergo catastrophic failure), solutions ...
