    Study Notes

    Function Analysis & Trimming

    • TMS/N/T1003 Systematic Innovation and Innovative Problem Solving
    • Semester 1 2022/2023

    Learning Objectives

    • Students should be able to describe function analysis.
    • Students should be able to illustrate the component analysis, interaction analysis, and function model process.
    • Students should be able to demonstrate the trimming process.

    Functionality

    • People buy functions/functionality, not products.
    • Understanding functions and functionality at the most basic level is fundamental to applying TRIZ effectively.
    • Solutions change, but functions stay the same.
    • Knowledge classification by function allows ready access to other solutions.

    Function Analysis

    • Component Analysis: Identifies components of the engineering system and its supersystem.
    • Interaction Analysis: Identifies the interaction between components.
    • Function Model: Identifies and evaluates the functions performed by components.

    Function Analysis (Detailed)

    • Subject: Carrier of the function (action verb).
    • Object: Parameters are changed/maintained due to the action.
    • Function Analysis is an analytical tool that identifies functions, their characteristics, and the cost of the system and the supersystem components.
    • Subjects and objects can be components.
    • A function is an action between a subject and an object, where the subject acts on the object and modifies/maintains a parameter.
    • A parameter describes some inherent property of a component.

    Function Language

    • Function models use simple language to describe functions, easily understood by children.
    • Using simple, descriptive language, instead of complex technical terms aids in envisioning and understanding potential solutions.

    Avoid Technical Jargon

    • Technical terms are potentially difficult for others to visualize, limiting the range of potential solutions.
    • Function language opens up the understanding of a broader range of potential solutions.

    Main Function

    • The product is what the engineering system is designed to accomplish and for which people pay.
    • Most engineering systems have only one product.
    • This is the primary function for the system.

    Main Useful Function

    • When analyzing an engineering system, define the system's purpose and its main useful function.
    • Example questions: What is the chair's purpose? What is the car's purpose?

    Exercises and Examples

    • Examples of function analysis: Door, bus waiting, toothbrush, table, bottle, cap, book, skipping rope.
    • Various examples of useful, useless, harmful, sufficient, and excessive functions in a refrigerator, gas stove, automobiles, computer, telephone. Detailed examples are shown for the exercises of the table, bottle, and cap.

    Component Analysis

    • An Engineering System comprised of internal and external elements
    • Internal and external elements continuously interact either directly or indirectly to maintain activity

    What is a Component?

    • Components are identifiable objects that form part of an engineering system.
    • Components can be substances that have mass (like a table) or fields that don't have mass (like a magnetic field).

    Supersystem Components

    • Components that interact with the engineering system but aren't part of the system. Air, floor, humidity, and dust are examples.

    Interaction Analysis

    • Interaction analysis is an analytical tool aimed at identifying and understanding component interactions in an engineering system.

    Function Model

    • Function models analyze the component interactions in an engineering system and supersystem.
    • Function models also highlight the advantages and disadvantages of actions on components.

    What is a Function Model?

    • The aim of function analysis is to determine specific drawbacks of a product, including harmful functions, insufficiently performed functions, and excessively performed functions.
    • Example categorization of function analysis into useful (normal), useful (insufficient), useful (excessive), and harmful functions.

    Definition of Interactions

    • Useful function: Product delivers its intended purpose as designed
    • Equal/Normal function: Product parameter values are equivalent to the required or designed values.
    • Insufficient function: Parameter values fall below the required or designed values.
    • Excessive function: Parameter values rise above the required or designed values.

    Harmful Functions

    • A harmful function worsens the object's parameters, causing harm for the object.

    Examples(Detailed)

    • Detailed refrigerator and gas stove examples
    • Detailed automobile example
    • Detailed computer and telephone examples

    Trimming

    • Trimming is a method of eliminating components from an engineering system
    • Trimming is used to reduce/remove disadvantages and improve the system's efficiency and reduce its costs

    Trimming Rules

    • Rule A: The function is no longer needed because the object no longer exists.
    • Rule B: The object performs the function.
    • Rule C: The function is transferred to another component within the system or the supersystem.

    Trimming Case Studies

    • Examples of how to trim a toothbrush and a skipping rope following the trimming rules

    Trimming Factor

    • A method of analyzing a product's cost and functionality to identify the best candidates for trimming.
    • Graphically compares product functionality with the problems and costs associated with it.
