This axioamtic part 1 of a 2-part article. This Standard Solution states: This corollary is a consequence of Axiom 1 and 2. When a given set of FRs is changed by the addition of a new FR, or substitution of one of the FRs by a new one, or by selection of a completely different set of FRs, the design solution given by original DPs cannot satisfy the new set of FRs.
The four-domain structure is schematically illustrated in figure 1. This means that two or more dependent FRs should be replaced by one equivalent FR. Corollary 1 Decoupling of Coupled Comparidon Decouple or separate parts or aspects of a solution if FRs are coupled or become interdependent in the proposed design.
The region of overlap is called the common range. Specify the largest allowable tolerance in stating functional requirements. These techniques were derived from the patent database, tdiz relates to novel methods and unique ideas.

Decoupling does not necessarily imply that the system has to be broken into two or more separate physical parts, or that a new element has to be added to the existing manufacturing system design. To use these tools, one identifies based on the model obtained in Su-field analysis the class of a particular problem and then chooses a set of Standard Solution accordingly.
Thus it is not obvious how or where to apply TRIZ knowledge base tools to aid the problem solving. However, mere physical integration is not desirable if it results in an increase of information content or in a coupling of functional requirements.
This pattern states that technological systems tend to develop first toward increased complexity i. Symmetrical parts promote symmetry in the manufacturing process.
A Comparison of Triz and Axiomatic Design
TRIZ offers a wide-ranging series of tools to help designers and inventors to avoid trial-and-error approach in design process and to solve problem in creative and powerful ways. Substance field analysis is a TRIZ analytical tool for building functional model for problems related to existing or new technological systems.

Gordon and Breach Science Publishers, A given set of FRs must be successfully mapped to a set of DPs in the physical domain prior to the decomposition of the FRs. Axiomatic design pays much attention to the functional, physical and process hierarchies cmoparison the design of a system. This corollary is a consequence of both Axiom 1 and Axiom 2.
Decisions made during the each step of design process will profoundly affect product quality and manufacturing productivity. If you like the TRIZ Journal, please help us by donating towards domain space, admin and technical support.
Corollary 2 Minimization of FRs Minimize the number of functional requirements and constraints.
A technological contradiction is derived from a physical contradiction. This situation can be modeled by a triangle whose corners represent objects and an action or interaction called a field. Design parameters that satisfy the functional requirements are defined in physical domain, and in process domain manufacturing variables define how the product will be produced.
The most part of TRIZ tools were created by means of careful research of the world patent database mainly desogn Russianso they have been evolved independent and separate from many of the design axioatic developed outside Russia.
The needs of the customer are identified in customer domain and are stated in the form of required functionality of a product in functional domain. Interchangeable parts allow for the reduction of inventory, as well as the simplification of manufacturing and service operations, i.
These Standard Solutions are separated into five classes according to their objectives; the order of solutions within the classes reflects certain directions in the evolution of technological systems. Functional decoupling may be achieved without physical separation. The number of plausible solutions for any given set of FRs depends on the imagination and experience of the designer.
The whole design process involves the continuous processing of information between and within four distinct domains. During the mapping process, one should not violate the independence axiom described above.
Axiomatic design is a general methodology that helps designers to structure oof understand design problems, thereby facilitating the synthesis and analysis of suitable design requirements, solutions, and processes. There are two types of contradictions: The way they generalize a specific situation is to represent a problem as either a contradiction, or a substance-field model, or just as a required function realization. Required function analysis is the first step to use this knowledge base to look up the recommendations for accomplishing the objective.
Two basic principles, Independence Deeign and Information Axiom, are derived from the generation of good design practices. In applying Effect Knowledge Base tool, one has to select a appropriate function the system wants to perform based on the required function analysis compraison, then the knowledge base provides many alternatives for delivering the function.
The knowledge base tools are different from analytical tools in that they suggest the ways for transforming the system in the process of problem solving while analytical tools help change the problem statement .
Since the complexity of the solution process necessarily increases with the number off FRs, it is important to describe the perceived design needs in terms of a minimum set of independent requirements. The basic premise of the axiomatic approach to design is that there are basic principles that govern decision making in design, just as the laws of nature govern the physics and chemistry of nature. Very early in his research, Altshuller recognized that given a difficult problem, the ideality and ease of implementation of a particular solution could be axiiomatic increased by utilizing various physical, chemical and geometric effects, thus axuomatic large vast of database has been developed.

comparisoh Fey and Eugene I. ARIZ is such anv sophisticated analytical tool that it integrates above three tools and other techniques. Part 2 appeared in September, Any problem solving process involves two components: Required function analysis refers to select the objective of the system and match it with the function list axxiomatic the TRIZ Effect Knowledge Base. So, certain changes of the physical structure of a technological system guided by Contradiction Table and 40 Inventive Principles or Separation Principles are often required to remove contradiction, though restatement of the problem may sometimes help to overcome contradiction.
Successful innovative experience shows that both problem analysis and system transformations are important to problem solving. These patterns indicate that there exist basic laws for engineering system development, and understanding them enhances ones ability to the design problem solving.
