Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the semiconductor apparatus operates at low temperatures, then energy consumption is reduced, but circuit operation stability deteriorates
Solution Approach 1:
The patent changes the operating temperature parameter dynamically based on environmental conditions. A temperature detecting circuit monitors the ambient temperature, and when low temperature is detected, the temperature raising circuit activates to heat the semiconductor apparatus to a predetermined temperature range, ensuring stable circuit operation while minimizing energy consumption during normal operation.
Solution Approach 2:
The patent implements a feedback mechanism where the temperature detecting circuit continuously monitors the temperature and provides input to the control circuit. Based on this feedback, the control circuit decides whether to activate the temperature raising circuit, creating a closed-loop system that maintains optimal operating temperature without excessive energy consumption.
2Reliability
If the temperature raising circuit is activated continuously, then circuit operation stability is improved, but energy consumption increases
Solution Approach 1:
The patent employs periodic action by activating the temperature raising circuit only when low temperature conditions are detected, rather than continuously. The control circuit monitors temperature and activates heating only when necessary, then stops when the predetermined temperature is reached, achieving stable operation with minimized energy consumption.
Solution Approach 2:
The patent applies preliminary action by proactively detecting low temperature conditions and activating the temperature raising circuit before circuit instability occurs. The temperature detecting circuit monitors environmental temperature and triggers heating in advance, preventing instability rather than reacting to it, thereby maintaining stability with minimal energy use.
