TRIZ 76 STANDARD SOLUTIONS PDF

I apologize for not having it in the first edition. The following format can be used for a power point presentation and notes pages. Thank you in advance for any comments for further improvement. This month the first of 5 parts of the Standard Solutions are in a reference article.

These are called technical contradictions by Altshuller. He also defined so-called physical or inherent contradictions: More of one thing and less of the same thing may both be desired in the same system.

For instance, a higher temperature may be needed to melt a compound more rapidly, but a lower temperature may be needed to achieve a homogeneous mixture. An inventive situation which challenges us to be inventive, might involve several such contradictions. Conventional solutions typically "trade" one contradictory parameter for another; no special inventiveness is needed for that.

Rather, the inventor would develop a creative approach for resolving the contradiction, such as inventing an engine that produces more acceleration without increasing the cost of the engine. Inventive principles and the matrix of contradictions[ edit ] Altshuller screened patents in order to find out what kind of contradictions were resolved or dissolved by the invention and the way this had been achieved. From this he developed a set of 40 inventive principles and later a matrix of contradictions.

Columns refer to typical undesired results. Each matrix cell points to principles that have been most frequently used in patents in order to resolve the contradiction.

For instance, Dolgashev mentions the following contradiction: increasing accuracy of measurement of machined balls while avoiding the use of expensive microscopes and elaborate control equipment. The matrix cell in row "accuracy of measurement" and column "complexity of control" points to several principles, among them the Copying Principle, which states, "Use a simple and inexpensive optical copy with a suitable scale instead of an object that is complex, expensive, fragile or inconvenient to operate.

A screen with a grid might provide the required measurement. As mentioned above, Altshuller abandoned this method of defining and solving "technical" contradictions in the mid s and instead used SuField modeling and the 76 inventive standards and a number of other tools included in the algorithm for solving inventive problems, ARIZ. Laws of technical system evolution[ edit ] Main article: Laws of technical systems evolution Altshuller also studied the way technical systems have been developed and improved over time.

From this, he discovered several trends so called Laws of Technical Systems Evolution that help engineers predict the most likely improvements that can be made to a given product. The most important of these laws involves the ideality of a system. Substance-field analysis[ edit ] One more technique that is frequently used by inventors involves the analysis of substances, fields and other resources that are currently not being used and that can be found within the system or nearby.

TRIZ uses non-standard definitions for substances and fields. Altshuller developed methods to analyze resources; several of his invention principles involve the use of different substances and fields that help resolve contradictions and increase ideality of a technical system. For instance, videotext systems used television signals to transfer data, by taking advantage of the small time segments between TV frames in the signals. SuField analysis produces a structural model of the initial technological system, exposes its characteristics, and with the help of special laws, transforms the model of the problem.

Through this transformation the structure of the solution that eliminates the shortcomings of the initial problem is revealed. SuField analysis is a special language of formulas with which it is possible to easily describe any technological system in terms of a specific structural model.

A model produced in this manner is transformed according to special laws and regularities, thereby revealing the structural solution of the problem. ARIZ - algorithm of inventive problems solving[ edit ] ARIZ Russian acronym of алгоритм решения изобретательских задач - АРИЗ algorithm of inventive problems solving is a list of about 85 step-by-step procedures to solve complicated invention problems, where other tools of TRIZ alone Sufield analysis , 40 inventive principles , etc.

Starting with an updated matrix of contradictions, semantic analysis, subcategories of inventive principles and lists of scientific effects, some new interactive applications are other attempts to simplify the problem formulation phase and the transition from a generic problem to a whole set of specific solutions. See the external links for details. Use of TRIZ on Management Problems[ edit ] Although TRIZ was developed from the analysis of technical systems, it has been used widely as a method for understanding and solving complex management problems.

Examples include finding additional cost savings for the legal department of a local government body: the inventive solution generated was to generate additional revenue [insert reference to cost-cutting in local government case study]. TRIZ is now an obligatory skill set if you want to advance within Samsung". The Association holds conferences with associated publications.

Humidity Water in Air Herbicides We will see below through our application of the Standards of Class 4 that there are actually additional resources routinely available to the farmer. Indirect Methods Standard 4. This is in effect the original approach to fertilizer applications; simply apply what fertilizers are available, and in the available amounts, with the available equipment. If the results are economically satisfactory, there is no need to perform measurement upon which more precise or sophisticated fertilization or soil treatment could be based. Alternatively, this standard could lead to modification of the seed stocks themselves for the purpose of increased yield in low fertility conditions. This is in fact being done extensively through plant genetics, hybridization and genetic engineering.

However, the 76 standard solutions of su-field analysis make the implementation of this tool difficult as they contain repetitive information from other TRIZ tools, give special favors in utilizing certain fields and can not be fully explained using the su-field model. Consequently, users may feel frustrated and often give up. The seven generalized standard solutions can be deployed to fix su-field models for all types of relationships between substance S1 and S2. Introduction of Su-Field Analysis Su-field analysis is a basic concept used to symbolize a technical system and identify its completeness and effectiveness. Recognized as one of the most valuable contributions of TRIZ, su-field analysis is able to not only model a system in a simple graphical approach and identify problems, but also offer standard solutions to improve the system. According to TRIZ, the rationale of creating a su-field model is that a system, with the ultimate objective to achieve a function, normally consists of two substances and a field. The term S1 is used to represent an object that needs to be manipulated.

At times like these, you need to develop creative solutions to the problems you face. But brainstorming depends on intuition and the existing knowledge of team members, and its results are often unpredictable and unrepeatable. TRIZ, however, is a problem-solving philosophy based on logic, data and research, rather than on intuition. It draws on the past knowledge and ingenuity of thousands of engineers to speed up creative problem solving for project teams. Its approach brings repeatability, predictability and reliability to the problem-solving process and delivers a set of dependable tools. This article walks you through the essentials of TRIZ. What is TRIZ?
