Business Context
Intervening at the first indication of abnormal equipment behavior can prevent serious failures, but shutting down or switching equipment too early may interrupt mission operations unnecessarily. Temporary parameter excursions, environmental effects, or sensor errors can resemble genuine degradation.
Space TRIZ Resolution
Fault intervention should use progressive responses. Initial abnormal behavior can trigger increased monitoring, reduced operating intensity, or temporary restrictions before complete shutdown becomes necessary. Escalation should occur according to persistence, severity, correlated evidence, and system consequence.
Applicable TRIZ Principles
Principle 16 – Partial or Excessive Actions applies limited protective intervention before full shutdown.
Principle 23 – Feedback adjusts the response as additional health information becomes available.
Principle 35 – Parameter Changes reduces equipment operating intensity during uncertain conditions.
Expected Outcome
Earlier protection against developing failures
Higher equipment availability
Fewer unnecessary shutdowns
Improved anomaly discrimination
Decision Indicators
Early indicators include:
Minor parameter excursions cause immediate equipment shutdown.
Operators routinely override automated protective responses.
Equipment continues operating normally after repeated false interventions.
Protection logic provides only normal and shutdown states.
Temporary degradation cannot be managed through reduced-performance modes.
