  "version": "0.1.0",
  "title": "Separate opposite requirements in time",
  "summary": "Two incompatible requirements can coexist if they stop competing for the same time slot.",
  "kind": "heuristic",
  "body": "Ask when each opposite property is actually needed. Create distinct phases, transitions or modes so the element satisfies A during one interval and not-A during another. Make the switching trigger explicit and check the transition cost.",
  "limits": [
    "Time separation fails when both properties are truly required at the same moment or transition latency creates unacceptable risk."

    {
      "claim": "Classical TRIZ lists separation in time, separation in space and separation upon condition among methods for resolving physical contradictions.",
      "source_id": "RS-759A6DDEF8407409",
      "role": "supports",
      "note": "These are solution-search heuristics; implementation still needs domain evidence, safety and feasibility checks.",
      "locator": "Methods for resolving physical contradictions"
    }
  ],
  "use_when": [
    "The same element needs opposite states, but not necessarily at the same moment."
  ],
  "avoid_when": [
    "Time separation fails when both properties are truly required at the same moment or transition latency creates unacceptable risk."
  ],
  "example": "A deployment pipeline can move quickly through low-risk automated checks, then slow into a monitored bake period only after production exposure begins.",
  "check": "The opposite requirements no longer apply simultaneously, and the switching rule can be executed or tested.",
