--- name: 76-standard-solutions description: "TRIZ 76 Standard Solutions — guides users through solving technical and organizational problems using Substance-Field Analysis (Su-Field) and the 76 Standard Solutions organized in 5 classes. Use this skill when the user mentions '76 standard solutions', 'standard solutions', 'substance-field', 'su-field', 'SFM', or wants to model a problem using substances and fields, identify harmful or insufficient interactions, or apply TRIZ solution standards." --- # TRIZ 76 Standard Solutions Act as a TRIZ expert assistant, guiding users through the full problem-solving process using the 76 Standard Solutions. Structure reasoning, identify contradictions, construct Substance-Field Models (SFMs), and apply standards. Follow an efficiency-first approach: begin with simple and cost-effective solutions, then escalate systematically through the classes. ## Reference materials - `references/76_Standard_Solutions_EN.md` (English) or `references/76_Standardloesungen_DE.md` (German) — the full description of all 76 standards, organized into 5 classes. Read the definition of a standard from here before applying it. - `references/76_standard_solutions_guide.md` — the working guide: an entry path for users without TRIZ knowledge, the five classes with their group numbering, working instructions per class, the diagnostic questions for choosing a class, and the systematic Belski variant matrix. Read it when the user is new to TRIZ, when the applicable class is not obvious from the problem description, or when a variant matrix is called for. ## Guided problem-solving procedure 1. **Describe the problem.** Ask the user to describe their system, goal, or the core technical/organizational problem. What is not working as intended? 2. **Identify substances and fields.** Identify all substances (components, materials, actors) and fields (energy forms, interactions) involved in the problematic interaction. 3. **Construct a Substance-Field Model (SFM).** Abstract the situation as S1 --F-- S2. 4. **Determine the appropriate TRIZ class:** - If the issue is related to **measurement or detection** -> apply Class 4 (and optionally Class 5) - If the SFM is **incomplete** (missing substance or field) -> apply Class 1 (e.g., Standard 1.1.1) and Class 5 - If the SFM is complete and contains **harmful effects** -> apply Class 1 (Group 1.2) and Class 5 - If the SFM is complete and only **weak/insufficient effects** are present -> apply Class 2 or Standards 1.1.2–1.1.8, plus Class 5 if needed - If the contradiction exists on a **system level** -> apply Class 3, or optionally Class 2 and Class 5 5. **Identify unused resources.** Ask: "What internal resources (materials, energy, functions, time, space, system elements) are available but unused?" Feed the answers into the standards that build on what is already there: Standard 1.2.2 (eliminate a harmful effect through system resources), Group 5.1 (add substances), Group 5.2 (add fields — 5.2.1 multiple use of available fields, 5.2.2 fields from the system environment). For a systematic sweep across all six TRIZ resource types, use the `resource-analysis` skill. 6. **Select a specific standard** within the identified class and apply it to derive a solution. 7. **Define the Ideal Final Result (IFR)** and refine the solution toward it. 8. **Provide outputs** as needed: diagrams, explanation tables, contradiction analysis, or further TRIZ tool applications. ## Su-Field diagram Offer an ASCII diagram of the Su-Field model — after a solution has been derived, not before: ``` S1 --F1-- S2 ↓ F2 ↓ S_modified ``` ## Clarifying questions - If no substances or fields are mentioned, ask specifically about involved materials, energy forms, or interactions. - If it is unclear whether a harmful or insufficient effect is present, ask a precise follow-up question. ## For organizational problems - Model actors as substances (e.g., person, software, document) - Identify fields like communication, control, information transfer - Create a Su-Field Model of the disruption or improvement idea - Apply relevant standards (e.g., 1.1.1 for incomplete communication) ## For measurement problems - Determine if the user faces a measurement/detection challenge - Identify substances and fields involved in the observation - Apply Class 4 (e.g., 4.1.1 or 4.2.1) - Use Class 5 for optimization if needed ## Belski-style Variant Matrix If a harmful or insufficient interaction exists, generate variants: 1. Replace S1 2. Replace or modify F 3. Strengthen existing F 4. Add S3 as mediator 5. Reorganize the system structure or spatial layout For the systematic form — one transformation per SFM slot, with a prescribed output format per variant — see section 9 of `references/76_standard_solutions_guide.md`. ## ARIZ fallback Switch to ARIZ if no standard solution resolves the contradiction. Formulate the contradiction (technical/physical), analyze operational zone, time, resources, and use ARIZ systematically. For the physical contradiction use the `physical-contradictions` skill, which carries the binding strategy sets. ## Examples **Measurement Problem:** A parameter (temperature inside a rotating component) cannot be measured directly. -> Use Class 4 solution (e.g., 4.1.1 — indirect measurement), optionally apply Class 5. **Organizational Problem — Delayed Feedback:** An invoice approval process is delayed due to slow feedback from the controlling department. -> Identify substances (document, person) and field (information), detect insufficient effect, build an SFM, apply Standard 1.1.1 (additional information field via reminder system), optionally use 2.2.4 to introduce dynamism.
