Study Notes
Function Analysis & Trimming
- This course covers systematic innovation and innovative problem-solving.
- The course is for semester 1, 2022/2023.
Learning Objectives
- Students should be able to describe function analysis.
- Students should be able to illustrate the process of component analysis, interaction analysis, and function model.
- Students should be able to demonstrate the trimming process.
Functionality
- People buy functions, not products.
- Understanding functions at a basic level is key to successful TRIZ application.
- Solutions may change, but the functions remain the same.
- Knowledge classification by function allows easy access to other solutions.
Function Analysis
- Component Analysis: Identifies components of the engineering system and its supersystem.
- Interaction Analysis: Identifies the interactions between components.
- Function Model: Identifies and evaluates functions performed by components.
Function Analysis (continued)
- Subject: The carrier of the function.
- Function (Action-verb): The action between subject and object.
- Object: The recipient of the action.
- Parameters are changed/maintained by the action.
- Function analysis is an analytical tool that identifies functions, characteristics, and the cost of the system and its components.
- Subjects and objects are components, or interact with the engineering system.
- A function is an action between a subject and an object. The subject acts upon, modifies or maintains a parameter of the object.
- A parameter describes some inherent property of a component.
Function Language
- Function models use simple language (easily understood by a child) to describe functions.
- Example: table holds book
- Example: table holds dog
- Example: Bristle removes food
- Example: String removes food
- Example: Stick removes food
Avoid Technical Jargon
- Technical language is sometimes difficult for people to grasp, limiting potential solutions.
- Function language enables a wider scope of potential solutions.
- Example: Technical Language: Etch, Distill, Encapsulate, Stream, Zip
- Example: Function Language: Remove, Separate, Include, Deliver, Reduce
Main Function
- The product is what the engineering system is designed to do or produce.
- Most engineering systems have only one product.
- The main function delivers the system product.
Main Useful Function
- When analyzing an engineering system, define the system's purpose.
- Example: What is the useful function of a chair? Holds a person.
- Example: What is the useful function of a car? Moves a driver.
Exercise Examples
- The table holds a bottle.
- The bottle holds liquid.
- The cap seals the bottle.
- The cap stops the liquid.
- The book informs a person.
- Door Functions: Allow person to pass, Stop person, Provide open passage; no functions between an open door and passing person.
- (Bus functions): Wait for bus, Waste time, Queue for bus.
- Toothbrush function: Clean teeth, Brighten teeth, Keep teeth clean, Prevent cavities, Make teeth healthy, Remove plaque, Remove food
Component Analysis
- Components of an engineering system include internal and external elements that interact with the system or co-exist with it.
- Components continually influence each other, either directly or indirectly, for system activity.
- Components: Substances or fields. Substances have mass (e.g. table, book); Fields have no mass (e.g. magnetic, electric field).
- Supersystem components interact with the engineering system but are not part of it.
Interaction Analysis
- Interaction analysis is a tool for recognizing and understanding interactions between engineering components/system
- It helps to identify and understand the interactions between components.
Function Model
- Function models analyze component interactions within the engineering system and the supersystem.
- Function models are essential to determine the efficiency/disadvantages of component functions
Function Model (Identifying Function Types)
- Useful function: Products, components, etc. achieve their intended purpose/deliver their purpose/functional requirements as designed (Normal/Insufficient/Excessive).
- Harmful Function: A function that worsens the parameters of the object of the function.
- Example: Excessive or unusual function type leading to harmful components to the object
- Example: A harmful function means the actual function performs undesirably
Example: Useful and Harmful Functions
- Refrigerator:
- Useful: Cool food, Maintain proper temperature.
- Useless: Heat back portion of the refrigerator.
- Harmful: Noise of compressor.
- Excessive: Excessive cooling of refrigerator.
- Insufficient: Insufficient cooling.
Example: Trimming
- Toothbrush: Trim the handle as is not needed for carrying out the primary function; functionality of removing the food particles can be retained with a simple rubber tip.
- Skipping Rope: Remove excessive components such as handles to enhance the primary functionality.
Trimming Rules
- Rule A: The function is no longer needed as the object of the function no longer exists.
- Rule B: The object being worked on by the function already performs the function itself.
- Rule C: The function is transferred to another component in the system or supersystem.
