  "title": "Use inventive principles after the contradiction is clear",
  "summary": "A creativity prompt works better when it is aimed at a named conflict.",
  "kind": "protocol",
  "body": "First state the technical or physical contradiction. Then use one or more TRIZ inventive principles as prompts for mechanisms—segmentation, prior action, local quality, periodic action and others—without treating the principle name as the solution. Translate each promising prompt into a concrete concept and test it against both sides of the contradiction.",
  "limits": [
    "The 40 principles are heuristic prompts derived from TRIZ practice, not a guarantee that one listed principle contains the answer."

  "example": "For throughput versus error exposure, segmentation may suggest smaller independent batches rather than one large compromise batch.",
  "check": "Each retained concept can explain how it changes the mechanism behind the contradiction.",
  "steps": [
    "Write the contradiction before opening a principle list.",
    "Select a small set of relevant principle prompts.",
    "Generate a concrete mechanism for each prompt.",
    "Test whether the concept improves the desired parameter without recreating the original harm.",
    "Discard clever-sounding concepts that do not resolve the stated conflict."
