Introduction to TRIZ Function Analysis

TRIZ Function Analysis is a systematic approach aimed at understanding and improving engineering systems by identifying and analyzing the functions within a system, their interactions, and the problems or contradictions they may present. This method, rooted in the Theory of Inventive Problem Solving (TRIZ), emphasizes the identification of the main functions of a system, categorization of these functions as useful, harmful, or excessive, and the analysis of the system's components and their interactions. An example of TRIZ Function Analysis could involve a simple mechanical pencil: the main function is to provide a writing capability by mechanically advancing the lead. The analysis would identify the pencil's components (lead, spring, button, etc.), their actions (advance, retract, hold), and the objects of these actions (lead, internal chamber, user's hand), aiming to optimize the writing process while minimizing lead breakage or unnecessary complexity.

Main Functions of TRIZ Function Analysis

  • Identification of System Components

    Example Example

    In a smartphone, components include the display, battery, processor, and camera.

    Example Scenario

    Analyzing how each component contributes to the device's overall functionality, such as display for output, battery for power, and camera for capturing images.

  • Analysis of Functional Interactions

    Example Example

    In a car braking system, the main components interact to decelerate the vehicle.

    Example Scenario

    Function analysis examines how the brake pedal, hydraulic fluid, brake pads, and discs work together to convert the driver's action into physical force that slows the car.

  • Identification and Resolution of Contradictions

    Example Example

    A laptop's need for high processing power versus its need for long battery life.

    Example Scenario

    Function analysis identifies this contradiction and explores solutions, such as optimizing software or hardware innovations to balance performance and energy consumption.

  • Elimination of Harmful Functions

    Example Example

    In manufacturing, harmful vibrations in machinery can lead to wear and tear.

    Example Scenario

    Function analysis can be used to identify the source of vibrations and redesign components or introduce dampers to mitigate this harmful effect.
