What is an inventive principle ?

Is a basic generalized rule that is accepted as facts, works in exactly the same way consistently and usually followed as a basis of reasoning or explanation of the invention

Presentation By Group

During the previous class, our class do some presentation about 40 Inventive Principles. Our group has been presenting about Principle 36 until Principle 40.

This is our pictures during that presentation

What is Trimming?

· Trimming is a method of eliminating Components from an Engineering System to reduce or eliminate the disadvantages of those trimmed Components · Trimming is used to increase the efficiency and reduce the cost of the Engineering System Example :

TRIZ process flow :

2 Key Steps : A) Function Analysis • Helps to clearly identify the Engineering System . • In function analysis we have the Supersystem, System and Subsystem. • Subsystem – component within Engineering system. • Supersystem – component outside system boundaries. Not designed as a part of the System. • System – components interaction between subsystem. B) Cause and Effect Chain Analysis • Help to identify the fundamental root cause(s). • These fundamental root causes are essentially the root causes of Engineering System problem which need to be resolved. Function can be categorized into two types : a) Useful i. ...

Cause and Effect Chain Analysis :

· A cause-and-effect analysis generates hypotheses about possible causes(reasons) and effects(results) of problems · A Cause & Effect Chain (CEC) analysis diagram is a structured way of expressing hypothesis about the causes of a problem or about why something is not happening as desired · It helps to focus attention on the process where a problem is occurring and to allow for constructive use of facts to narrow down on the actual causes · It cannot replace empirical testing of these hypotheses, it does not tell which is the root cause, but rather the possibilities Example :
