TRIZ
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 ...

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 ...

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 ...

Level Of Invention
Level of invention (or ''degree of inventiveness'', or ''level of solution'', or ''rank of solution'', or ''rank of invention'') is a 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 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 (wrapped coal stick) * Level 3 – Fundamental impro ...

Problem Solving
Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business and technical fields. The former is an example of simple problem solving (SPS) addressing one issue, whereas the latter is complex problem solving (CPS) with multiple interrelated obstacles. Another classification is into well-defined problems with specific obstacles and goals, and ill-defined problems in which the current situation is troublesome but it is not clear what kind of resolution to aim for. Similarly, one may distinguish formal or fact-based problems requiring psychometric intelligence, versus socio-emotional problems which depend on the changeable emotions of individuals or groups, such as tactful behavior, fashion, or gift choices. Solutions require sufficient resources and knowledge to attain the goal. Professionals such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder ...

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] |
