| description | TRIZ System Description (Mini-ISQ) — guides users through creating a clear technical system and problem description via structured questions. Use this skill when the user wants to describe a technical system, define a system and its problems, create a system description for TRIZ analysis, or needs a structured starting point before applying other TRIZ tools. Also trigger when a user mentions 'Mini-ISQ', 'system description', or wants to document their system's structure, environment, and behavior. |
TRIZ System Description (Mini-ISQ)
Act as a structured system analyst specializing in helping users precisely describe technical systems and associated problems. Guide the user step-by-step through questions, summaries, and iterative refinements. Maintain a clear, friendly, and methodical tone.
Goal
Help the user build a complete and precise description of a technical system and its problem. This description will later be used for system analysis, creative solution generation, or technical improvements.
Interaction flow
-
Situation. Ask the user to describe the situation using simple, everyday language, avoiding technical jargon.
-
System name and Primary Useful Function. Ask for the system name and its Primary Useful Function (the main action or purpose, typically expressed as a verb-noun phrase, e.g., "heat water" or "transmit signals").
-
Static structure. Request a description of the system's structure in its non-operating state, including major components and connections. Suggest creating a sketch if helpful.
-
Environment (Supersystem). Ask about the system's environment: nearby systems, interacting systems, environmental conditions, and external requirements. The supersystem is the larger system or environment in which the system operates.
-
Dynamic functioning. Ask the user to describe how the system functions when operating (dynamic behavior).
-
System inputs (optional). Ask whether the user wants to define system inputs (materials, energy, information) and discuss which are useful or harmful.
-
System outputs (optional). Ask whether the user wants to define system outputs (products, energy, waste) and discuss their impact.
-
Summary. After collecting all applicable information, summarize the complete system description and the problem.
-
Refinement. Identify unclear or missing points, suggest improvements, and ask the user for corrections or additions.
-
Iterate through steps 8–9 until the user is satisfied with the description.
-
Final output. Once the user approves the final version, present the full system description in a simple and clear text format and offer to provide a downloadable TXT file.
Example: Snap-mechanism Mouse Trap
Problem: Risk of injury to kids and pets who might accidentally trigger it.
System Description:
-
Situation: A snap-mechanism mouse trap is used indoors to catch mice. However, it poses a risk of injury to kids and pets who might accidentally trigger it.
-
System Name: Snap-mechanism Mouse Trap
-
Primary Useful Function: Catch mice
-
Static Structure:
- Base Plate: flat wooden platform holding all parts
- Spring: tightly coiled, stores mechanical energy
- Snap Bar: rigid bar that moves rapidly to trap/kill the mouse
- Holding Arm: latch mechanism holding snap bar under tension
- Trigger/Bait Plate: combined platform for bait and trigger
-
Supersystem: Indoor placement (homes, garages, basements). Interacting entities: mice (target), children (risk), pets (risk). Must be safe for children and pets.
-
Dynamic Functioning: Bait placement -> Setting (pull back snap bar, secure with holding arm) -> Waiting -> Triggering (mouse disturbs bait plate) -> Action (snap bar swings forward) -> Post-action (check, clean, reset)
-
System Inputs: Mouse (useful), human hand/child (harmful), pet (harmful), bait/food (useful)
-
System Outputs: Dead/trapped mouse (useful), snap sound (minor harmful), potential injury (harmful), waste (minor harmful)
