DFT1012 Inventive Problem Solving

·       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 :

·    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 :

Product Analysis : Component Analysis Component is an identifiable Object that make up a part of an Engineering System Interaction Analysis Interaction Analysis is an analytical tool that identifies and understands the interaction between the components of the Engineering System Function Analysis Function Model is an analysis of the interaction between components of the Engineering System and Supersystem.   It identifies the advantages and disadvantages of the functions acting on each of the components. Structural Analysis  

Function Analysis : •     Function Analysis is an analytical tool that identifies Functions, their characteristics, and the cost of the System and the Supersystem Components •     Subject and Object are both Components in, or interact with, the Engineering System •     A Function is an action between a Subject and an Object, in which the Subject acts upon and modifies or maintains a parameter of the Object •     A parameter describes some inherent property of a Component Main Function: Delivers the system product •     The Product is what the Engineering System was designed to do or produce and the one that people pay for •     Most Engineering Systems contain only one Product Example What is Function Model ? The main goal of Function Analysis is to identify specific disadvantages of an Object - namely, harmful Functions as well as useful Functions performed insufficiently, and those that are performed excessively Definition of Interactions

TRIZ Tool : Structured Problem Solving What is Structured Problem Solving? Structured problem solving provides a systematic approach to advance from the identification of a problem to the solution. Step-by-Step Process 1.     Define Problem : Purpose •        Identify the problem and the importance of working on it Output •        Establish a team •        Develop Problem Statement 2.     Current Solution : Purpose •        Clarify the problem areas as the situation exists today Output •        Create a problem description 3.     Identify Causes : Purpose •        Identify and verify the root causes of the problem Output •        Isolate and verify the root cause of the problem 4.     Develop Solution : Purpose •        Develop and test solutions to eliminate the root cause Output •        Fix the problem at the root cause level •        Generate no additional problems 5.     Implement Solution : Purpose •        Imple

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
