    Study Notes

    LU3: Problem Solving Tools

    • Problem-solving tools include Engineering Contradictions, Physical Contradictions, and the Substance Field Model.

    TMS/N/T 1003 Systematic Innovation and Innovative Problem Solving

    • This is a course focused on systematic innovation and innovative problem solving.

    Contradiction

    • A contradiction is a situation where improving one aspect of a system negatively impacts another.
    • Improving one parameter of a system leads to worsening (impairment) of another parameter.
    • This interaction between components can be both positive and negative.
    • Example: Increasing the diameter of table legs improves strength, but increases weight.
    • Example: An axe needs to be heavy for strong splitting, but light for easy handling.

    Engineering Contradiction

    • An attempt to improve one part of a system negatively alters another.
    • One characteristic gets better, but another gets worse.
    • Example, a heavier axe is more powerful for splitting, but also clumsier to handle.
    • Example: An airplane needs strong, heavy engines to generate enough power, but needs light engines that won't damage the runway.
    • Example: A platform needs to be high, so a diver has time to complete a routine, but needs to be low to avoid harm on entry.
    • Example: An umbrella needs to be large to avoid getting wet, but needs to be small to prevent wind damage.

    Physical Contradictions

    • These are product or system contradictions where two beneficial needs are in conflict.
    • Example: An airplane needs strong, heavy engines to generate enough power but needs light engines that won't damage the runway.

    TRIZ Tool: Engineering Contradiction

    • This discusses engineering contradictions as a tool for problem solving
    • Includes questions on defining contradictions, system parameters, inventive principles, and contradiction matrix usage
    • Contradictions are common in systems design and problem-solving

    Contradiction Matrix

    • A 39x39 matrix to categorize and understand opposing system parameters.
    • The X-axis represents parameters that worsen, while the Y-axis represents parameters that improve.
    • Used to identify inventive principles for solving contradictions.
    • The matrix visually displays the relationships between 39 parameters that can be improved or worsened

    Inventive Principles

    • Simple methods for resolving engineering contradictions.
    • No special knowledge is needed to apply them.
    • Methods for using them include a matrix (Method 1)- listing recommended principles to solve a contradiction, or Method 2 - applying all 40 principles to solve contradictions.

    Example: Umbrella

    • An umbrella needs to be large to prevent getting wet while staying small to avoid breaking in the wind.

    Separation in Space, Time

    • Separation in space/time is a technique to resolve contradictions.
    • Involves separation of attributes in different places or situations.
    • Different methods of separation can be used depending on the problem, such as in time, space, and system

    Ideal Final Result

    • Ideal result is the desired state or solution based on a contradiction.

    Separation Methods

    • Simple methods exist for resolving engineering contradictions.

    • No special knowledge is required to apply these methods.

    • Methods include a matrix approach (Method 1) for listing recommended principles to solve a contradiction, or Method 2 which involves applying all 40 principles.

    Example: Umbrella

    An umbrella must be large enough to keep users dry, yet small enough to withstand the wind without breaking.

    Separation in Space/Time

    • This technique involves separating attributes in different locations or situations to resolve contradictions.

    • Separation in Space: This concept involves using distinct physical locations to meet functional goals, fostering task specialization, efficiency, and resource allocation. It minimizes interference and enhances productivity through spatially segregated activities. Separation in Time: This principle organizes activities into stages or schedules them differently, optimizing workflows and ensuring focused attention on each project phase, preventing unnecessary overlaps. Separation by System: This aspect emphasizes segmenting system sections for clearer organization, allowing teams to manage complex structures effectively. Separation by Relation: This involves setting specific conditions for system components to optimize performance and reliability.
