Introduction to TRIZ/TIPS Analysis

Typical and non typical problems u Typical problems from engineer viewpoint u u Typical problems from TRIZ viewpoint u u 지식을 통해 solutions이나 rules을 알고 있는 문제 경험을 통해 solutions이나 rules을 알고 있는 문제 동일 분야의 특허, EDB 등의 정보를 통해 알고 있는 문제 Engineer viewpoint에서 Non-Typical Problem을 포함 이러한 유형의 문제에 TRIZ는 Typical Solutions을 적용함 - 많은 발명가들의 경험으로부터 추출된 지식/원리/Rule 기술과제에 대한 Situation Modeling을 통해 Typical Problem으 로 변환할 수 있다. Non Typical problem u TRIZ의 typical solutions 이나 기존의 experience을 통해 이러한 유형의 문제를 해결할 수 없다.

Example 1. Step A. A thermometer for weevils Once scientist got together to discuss the problem about weevils. It was found that the conditions of existence of this small beetle had been studied very little. Nobody knew, for example, what the body temperature of weevils. "The weevil is very small", said one scientist. "You can not use regular thermometer". "We have to design special device, " agreed another scientist. "This will require a lot of time. " What should be done? 쌀벌레의 온도를 측정하는 기술을 모른다면 이 문제는 Non. Typical Problem 이다. H. Altov. And suddenly the Inventor Appeared 1989

Example 1. Step B. A thermometer for weevils Usually proposed solution as first idea, if we use trial and error approach. Real working idea: to collect a lot of weevils and put them into the glass. In this case we can use regular thermometer. Thermometer will indicate mean temperature of a weevil. 이 문제를 해결한 원리인 (Incorporation of similar or different objects into one system) 을 이용해서 다음 문제를 해결해 보자. H. Altov. And suddenly the Inventor Appeared 1989

Example 2. Step A. Glass filters A plant got an order to manufacture glass filters of one meter in diameter and two meters high. Holes were to be made evenly throughout the filter. Engineers looked at the drawings and were shocked: thousand of tiny holes had to be made in every filter. "How should we make these holes? " the chief engineer asked his subordinates. "Are we going drill them? " What should be done? Can we use principle Incorporation of similar or different objects into one system for this problem? H. Altov. And suddenly the Inventor Appeared 1989

Example 2. Step B. Glass filters Three ways of production Glass filter are presented after using Principle Incorporation of similar or different objects into one system H. Altov. And suddenly the Inventor Appeared 1989

Altshuller's TRIZ u u TRIZ는 50년전에 Russian scientist & engineer인 Genrich Altshuller에 의해 비롯됨. 연구목적은 engineering problems과 기존 solutions(특허, 발명 )의 유사점 발견. 10여년의 연구를 통해 Inventive Problem의 발생원인과 창조 적 설계를 위한 Principle을 도출함. 이후 Altshuller’s approach는 구소련의 많은 연구자와 참여자 의 도움으로 이론적 발전을 이룸. Altshuller's Theory of Inventive Problem Solving (TRIZ)는 innovative engineering design 1 을 위해 domainindependent techniques을 추출하여 체계화한 이론 1 Altshuller 1984.

First level - routine solutions First level solutions have not contradiction. Its are not invention (from TRIZ view point). But these solutions can be patented. A pliers having increased gripping capacity US Patent 5572914

Second level - trivial inventions Contradiction can be resolved, without knowledge of other domain. For checking air-tightness of container we can use tank with liquid. If container has not air-tightness, after pulling in liquid we will remark bubbles. But if we have a lot of containers and tanks, operator can miss bubbles. How to delay bubbles near surface of liquid? Tried to cover surface of liquid by glass, but liquid level is changed. Solution: Cover surface of liquid by special grid. Bubbles were stopped between cells of grid. SU A. c. № 1193478 Salamatov Y. P. How to become of inventor: 50 hours of creativity. Moscow, Prosveschenie 1990.

Ideal Final Result (IFR) Ideal Final Result gives us directions for the solutions Pattern: <Object> itself, without additional costs, executes <required action (function)> IFR 1: <Frozen product> itself, without additional costs, executes <report whether products were unfreezed during vacancy> IFR 2: <Air> itself, without additional costs, executes <report whether products were unfreezed during vacancy> IFR 3: <Cabinet walls> itself, without additional costs, executes <report whether products were unfreezed during vacancy>

Contradiction A contradiction arises when two mutually exclusive design requirements are put on the same object or a system Pattern: TC 1: <Frozen product> has to <report whether products were unfreezed during vacancy>, Because <we want to know the quality of products>. <Frozen product> doesn't have to <report whether products were unfreezed during vacancy> Because <it hasn't device for this function>.

Example: Engine’s Cowling When The Boeing Company was developing a modification of its 737, it was necessary to replace existing engines with more powerful ones. The more powerful an engine, the more air it needs, and therefore the diameter of the cowling has to be larger. The distance between the cowling of a more powerful engine and the ground would be too close.
