This paper compares the Theory of Inventive Problem Solving (TRIZ) and Axiomatic Design (AD). Both AD and TRIZ are briefly reviewed and their possible . Abstract: Axiomatic design (AD) and theory of inventive problem solving of the differences and similarities between AD and TRIZ. 2 Review of AD and TRIZ. reviewing the use of axiomatic design (AD) within a TRIZ framework and making based on application similarities and differences found in the literature.

The corollaries and theorems, which are direct consequences or are derived from the axioms, tend to have the flavor of design rules. In TRIZ standpoint, a challenging problem can be expressed as either a technical contradiction or a physical contradiction.

These tools are developed based on the accumulated human innovation experience and the vast patent collection. Any problem solving process involves two components: Decisions made during the each step of design process will profoundly affect product quality and manufacturing productivity. The most part of TRIZ tools were created by means of careful research of the world patent database mainly in Russianso they have been evolved independent and separate from many of the design strategies developed outside Russia.

Corollary 3 Integration of Physical Parts Integration design features into a single physical process, device or system when FRs can be independently satisfied in the proposed solution. Not only should the shape be adiomatic wherever possible, but hole location and other features should be placed symmetrically to minimize anv information required during manufacture and use. Achieve the Right Design.

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 Axiomatic Design approach to the execution of the above activities is based on the following key concepts: It is self-evident that symmetrical parts are easier to manufacture and easier to orient in assembly. A and Aximoatic N. This corollary is a consequence of both Axiom 1 and Axiom 2.

Figure 4 illustrates the basic structure of TRIZ. Contradiction Analysis is a powerful tool of looking problem with the new perspective. Axiom 2 information axiom: The number of plausible solutions for any given set of FRs depends on the imagination and experience of the designer.

Invention Machine Lab 2. Corollary 4 Use of Standardization Use standardization or interchangeable parts if the use of these parts desivn consistent with FRs and constraints.

Seek an uncoupled design that requires less information than coupled designs in satisfying a set of FRs. Studies of patent collections by Altshuller, the founder of TRIZ, indicated that only one per cent of solutions was truly pioneering inventions, the rest represented the use of previously dsign idea or concept but in a novel way [2]. These patterns and other TRIZ tools are revealed by analysis of hundreds and thousands of inventions available in the world patent database.

Then corresponding knowledge base tools are applied once the problem is analyzed and modeled. In TRIZ standpoint, a technological problem becomes an invention one when a contradiction is overcome.

Axiomatic design is a general methodology that helps designers to structure and understand design problems, thereby facilitating the synthesis teiz analysis of suitable design requirements, solutions, and processes.

Where, P is the probability of successfully satisfying the functional requirements. Symmetrical parts promote symmetry in the manufacturing process.

deeign Contradiction table recommends which principles should be considered in solving approximately contradictions. The four-domain structure is schematically illustrated in figure 1. 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.

This corollary is a consequence of Axiom 1 and 2.

Corollary 1 Decoupling of Coupled Design Decouple or separate parts or aspects of a solution if FRs are coupled or become interdependent in the proposed design.

Since the complexity of the solution process necessarily increases with the number of FRs, it is important to describe the perceived design needs in terms of a minimum set of independent requirements.

A substance may be a article or tool and the field may be some form of energy. But where this idea could be found?

In the process design, a set of process variables PVs is created by mapping the DPs in physical domain to the process domain. Typically, a function represents some action toward a certain objects, and this action is performed by another object.

Contradiction analysis is the fundamental step to apply 40 inventive principles, one of the knowledge base tools. Figure 3 is a graphic interpretation of the general mapping process between functional and physical domains, and abd physical and process domains. These patterns can be employed for conscious development of technological system and inventive problem solving, replacing the inefficiencies of blindly searching.

No Patterns, principles or tools correspond to this corollary. Technical Innovation Center, Inc.

Corollary 2 Minimization of FRs Minimize the number of functional requirements and constraints. Conparison 6 is a general rule of design and it is nothing to do with invention. To satisfy the Independence Axiom, matrix [A] and [B] must be either diagonal or triangular. Submit an Article Contact us. Editor On 19, Aug 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 adn contradiction, though restatement of the problem may sometimes help to overcome contradiction.

ahd ARIZ is a step-by-step methodwhereby, given an unclear technical problem, the inherent contradictions are revealed, formulated and resolved. This pattern states that technological systems tend to develop first toward increased complexity i. TRIZ analytical tools, which include ARIZ, substance field analysis, contradiction analysis and required function analysis, are used for problem modeling, analysis and transformation.

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.
