Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving circuit uses a fixed driving signal, then the circuit design is simple, but the electronic unit cannot maintain stable operation under temperature changes
Solution Approach 1:
The patent implements dynamic adjustment of driving signals based on ambient temperature detection. The driving circuit transitions from a fixed signal approach to a dynamic signal generation system that adapts to temperature changes, thereby maintaining operational stability while managing complexity through temperature-based control strategies
Solution Approach 2:
The patent changes the driving signal parameters (such as current magnitude, pulse width, or frequency) according to detected temperature variations. This allows the electronic unit to operate stably across different temperature conditions by adjusting key electrical parameters in response to environmental changes
2Reliability
If the driving circuit adjusts driving signals according to ambient temperature, then operational stability is maintained, but the device complexity increases
Solution Approach 1:
The patent incorporates a temperature sensing mechanism that provides feedback to the driving circuit. This feedback loop enables the driving circuit to automatically adjust its output based on real-time temperature information, maintaining operational stability through closed-loop control while managing complexity through systematic feedback processing
Solution Approach 2:
The driving circuit is designed to automatically adjust its own operating parameters based on temperature feedback without requiring external intervention. This self-service capability maintains operational stability while minimizing the need for additional external control systems, thereby managing overall device complexity
