Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device sequentially transmits magnetic pulses in multiple radiation patterns to ensure compatibility with various POS terminals, then the adaptability to different POS terminals is improved, but the transaction time and power consumption increase

Engineering Contradiction:
