Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If semiconductor integrated circuits are used in extreme temperature conditions, then the operating range is expanded, but the characteristic changes of elements cause malfunction
Solution Approach 1:
The temperature detection system is divided into multiple detection units, each responsible for detecting a specific temperature range. Each unit contains transistors configured to detect temperature within its designated interval, allowing the system to cover a wide temperature range while maintaining accurate detection at each segment.
Solution Approach 2:
The invention changes the operational parameters of transistors by configuring them with different threshold voltages and current characteristics. By adjusting the gate-source voltage and drain current parameters of individual transistors, each detection unit responds to specific temperature intervals, enabling the system to adapt to extreme temperature conditions while maintaining reliable operation.
2Measurement precision
If temperature detection accuracy is improved, then temperature control is enhanced, but the complexity of detection units increases
Solution Approach 1:
Each temperature detection unit uses a standardized transistor-based structure that can detect temperature across different intervals. The same basic circuit topology is reused for each temperature range, with only the transistor parameters being adjusted. This universal design reduces overall system complexity while maintaining detection accuracy across multiple temperature intervals.
