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.

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. These tools are developed based on the accumulated human innovation experience and the vast patent collection. Hierarchical decomposition in one domain cannot be performed independently of the compariwon domains, i. This corollary states that functional independence must be ensured by decoupling if a proposed design couples the functional requirements.

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. Decisions made during the each step of design process will profoundly affect product quality and manufacturing productivity.

It states that a good design maintains the independence of the functional requirements. In TRIZ standpoint, a technological problem becomes an invention one when a contradiction is overcome. In the product design, the creation or synthesis phase of design involves mapping the FRs in the functional domain to design parameters DPs in the physical domain. The second axiom is the information axiom and it establishes information content as a relative measure for evaluating and comparing alternative solutions that satisfy the independence axiom.

However, in many cases, such physical decomposition may be the best way of solving the coupling problem. Each of solution is a recommendation to make a specific change to a system for the purpose of eliminating kf contradictions.

Aaxiomatic this case, enhancing Su-field model is required to improve the system functions. Where, P is the probability of successfully satisfying the functional requirements. There are eight patterns and each pattern consists of several sub-patterns or lines [9].

IFR helps an engineer to focus on concepts that minimize requirements in substance, energy and complexity of engineering product and process.

Tags axiomatic comparison design. Required function analysis refers to select the objective of the system and match it with the function list in the TRIZ Effect Knowledge Base.

On the other hand, if the tolerance is too large, then the error in axjomatic may accumulate such that FR cannot be satisfied. Since it becomes increasingly difficult triiz manufacture a product as the tolerance is reduced, more information is required to produce parts with tight tolerances.

It states there is always an uncoupled design that involves less information than a coupled design.

This is part 1 of a 2-part article. Corollary 2 states that as the number of functional requirements and constraints increases, the system become more complex and thus the information content is increased. The addition of a new FR, or substitution of one of the FRs by a new one means the previous system is an inefficient Su-field model, i. Corollary 2 Minimization of FRs Minimize the number of functional requirements and constraints.

During the mapping process, one should not violate the independence axiom described above. Minimize the number of functional requirements and constraints.

In the process design, a set of process variables PVs is created by mapping the DPs in physical domain to the process domain. In general, any properly functioning system can be desiggn with a complete triangle as shown in figure 5.

Interchangeable parts allow for the reduction of inventory, as well as the simplification of manufacturing and xesign operations, i. When there are n functional requirements, the total information is given by equation 7.

A Comparison of Triz and Axiomatic Design

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 axiomahic the new set of FRs.

Corollary 6 is a general rule of design and it is nothing to do with invention. Axiomatic design is a general methodology that helps designers to structure and understand design problems, thereby facilitating the synthesis and analysis of suitable design requirements, solutions, and processes.
