Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional avionics systems are designed for high reliability in harsh environments, then system durability is improved, but system complexity and difficulty of maintenance increase

Engineering Contradiction:
Improvesystem reliabilityVSAvoidsystem complexity
Core Design Contradiction:
