Study Notes
LU3: Problem Solving Tools
Engineering Contradictions
- A situation when improving one aspect of a system worsens another
- The improvement in one characteristic degrades another
- Examples given include: increase in lift size increases load-carrying ability but also adds weight; increasing car power improves speed but worsens fuel consumption.
TRIZ Tool: Engineering Contradiction
- Explores what Engineering Contradiction is
- Explains System Parameters and Inventive Principles
- Includes practical exercises and case studies
- Provides instructions for using a Contradiction Matrix
What is an Engineering Contradiction?
- An attempt to enhance a system parameter negatively impacts another parameter.
- Positive and negative interactions exist between components
- Diagrams illustrate these interactions
Inventive Principles
- Simple methods to solve engineering contradictions
- Application doesn't require specialized knowledge
- Two ways to apply the Inventive Principles
- Method 1: Use the Contradiction Matrix to pinpoint applicable principles for resolving the contradiction
- Method 2: Thoroughly understand all 40 Inventive Principles and apply them to solve the contradiction
Contradiction Matrix
- Organizes and formalizes Inventive Principles
- Created by Altshuller and colleagues
- 39 x 39 matrix plots worsening/improving parameters in opposition
- The x-axis represents the worsening parameter; the y-axis represents the improving parameter
- Used to solve contradictions
Engineering Contradiction vs Physical Contradiction
- Engineering Contradiction: An attempt to improve one characteristic leads to the worsening of another.
- Physical Contradiction: One characteristic (e.g., weight) should be heavy for one task and light for another.
Ideal Final Result
- Diagrams and examples highlight the need to address contradictions through a process that balances both opposing needs (eg light for handling but heavy for splitting).
- Results are solutions to overcome the contradiction.
Physical Contradictions
- Examples include:
- Products must be strong (thick) and light (thin)
- Software options should be few for ease of use but many to be effective
- Coffee should be hot for enjoyable drinking but cold to avoid burning.
- Airbags should deploy quickly to save life but slowly to minimize harm.
Resolving Physical Contradictions
- Three main approaches: Separation, Satisfaction, Bypass
- Separation explained in terms of Time and examples of each such as, ink flowing while writing, ink stopping when writing, and chains being flexible or rigid depending on need.
Inventive Principles for resolving physical contradictions
- Separation
- Satisfaction
- Bypassing
Separation in Space and Time
- Principles for separation are given; examples include cutting something to improve a property and another property, changing the amount of time something takes or changing one variable based on another variable
Choosing the Separation Method
- Separation types include time, space, a relationship in conditions, and system
- Each type has particular characteristics of when to apply them
Example of Physical Contradiction Resolution
- Shows that different approaches may be used to solve contradictions
Physical Contradiction Solution
- Specific examples of solving contradictions for specific tasks (e.g., Axe, Radiation intensity)
Guide to help find resources available
- A guide to help discover available resources for solving a problem
MCQ Design
- Standard Multiple Choice Questions are easy to use for group testing
- However, they can lack the ability to be customized to specific subjects, meaning, they might not be as practical
