trimming

TRIZ Trimming and Trimming Rules — streamlines engineering systems by identifying and eliminating unnecessary components while preserving essential functions using Rules A, B, and C. Use this skill when the user mentions 'trimming', 'trim components', 'simplify system', 'eliminate components', or wants to reduce system complexity, remove unnecessary parts, or apply TRIZ trimming rules to cut costs and simplify designs.

description: TRIZ Trimming and Trimming Rules — streamlines engineering systems by identifying and eliminating unnecessary components while preserving essential functions using Rules A, B, and C. Use this skill when the user mentions 'trimming', 'trim components', 'simplify system', 'eliminate components', or wants to reduce system complexity, remove unnecessary parts, or apply TRIZ trimming rules to cut costs and simplify designs.

# TRIZ Trimming and Trimming Rules Guide the user through step-by-step application of TRIZ Trimming to identify and eliminate unnecessary components while preserving essential functions. ## Interaction flow 1. **Describe the system.** Ask the user to describe the technical system they want to apply Trimming to. 2. **Component analysis.** Guide them through identifying super-system, system, and sub-system components. 3. **Function analysis.** Perform function analysis in tabular form: Tool | Action | Object | Result | Function 4. **Select component to trim.** Ask the user which component (Tool) from the function analysis they want to trim. 5. **Formulate the Trimming Key Problem:** - "If we trim [Component], Then [Positive Outcome], But [Negative Outcome]" - Generate: "How can we achieve [Positive Outcome] without [Negative Outcome]?" 6. **Solve using Trimming Rules.** ## Trimming Rules ### Rule A — Remove the object The tool (function carrier) can be trimmed if the object of its useful function is removed. ### Rule B — Object performs the function itself The tool can be trimmed if the object performs the useful function itself. ### Rule C — Another component takes over The tool can be trimmed if another component performs the function. Apply these guidelines: 1. Component performs the same function on the same object 2. Component performs the same function on a different object 3. Component performs another function on the same object 4. Component has the resources to perform the function ## Key concepts A system is defined by its main function. The targets of the system are those components whose parameters are changed by this main function. **Examples:** - A car's main function is to move passengers and cargo (targets) - A toothbrush removes plaque (object) by changing its location - A refrigerator moves heat to the outside — making it similar in function to a heater

mpv-analysis

TRIZ MPV Discovery — structured facilitator for finding the Main Parameters of Value (MPVs) of a product, process or service, from the business challenge through Voice-of-the-Product analysis to validated MPVs and the physical parameters behind them. Use this skill when the user mentions 'MPV', 'PV', 'HPW', 'main parameter of value', 'Hauptparameter des Wertes', 'MPV Discovery', 'parameter of value', 'Voice of the Product', 'latent parameter', or wants to know where to innovate, what customers would actually pay for, or which product characteristics decide the purchase.

function-analysis

TRIZ Function Analysis for technical systems — identifies tools, actions, objects, and functions, clarifies component relationships, and reveals the system's main function. Use this skill when the user wants to perform a function analysis, identify functions in a technical system, map tools-actions-objects, create a function model, or analyze component interactions. Also trigger on mentions of 'function analysis', 'function model', 'tool-action-object', 'function carrier', or when the user wants a CSV for the TRIZ Function Analysis Diagram Tool or TIRAZIS.

ideality

TRIZ Ideality — optimize technical systems by reducing harm, enhancing usefulness, managing resources, and adding new functions. Use this skill when the user wants to increase system ideality, reduce complexity, improve performance without adding resources, define the ideal system, or mentions 'ideality', 'ideal system', 'ideal technical system', or wants to move a system toward its ideal state. Does NOT handle resource analysis in isolation and does NOT formulate the Ideal Final Result (IFR) — use triz_resource_analysis for both.
