Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power supply is increased to improve performance, then productivity is improved, but temperature rises causing heat damage
Solution Approach 1:
The temperature sensor is positioned to detect temperature before critical damage occurs, and the control circuit proactively restricts power supply when threshold is approached, preventing heat damage before it happens
Solution Approach 2:
The system continuously monitors temperature via the temperature sensor and dynamically adjusts power supply based on real-time temperature feedback, creating a closed-loop control system that balances performance and safety
2Temperature
If power supply restriction is implemented to prevent overheating, then temperature is controlled, but productivity decreases
Solution Approach 1:
The power supply restriction is not static but dynamically adjusted based on real-time temperature conditions, allowing full power when cool and progressive restriction only when necessary, optimizing both temperature control and productivity
Solution Approach 2:
The system changes the power supply parameter dynamically based on temperature measurements, adjusting the operating parameters to maintain optimal performance while preventing overheating
3Reliability
If temperature monitoring is added to prevent heat damage, then reliability is improved, but device complexity increases
Solution Approach 1:
The temperature monitoring and power restriction system operates autonomously without requiring external intervention, with the control circuit automatically responding to temperature sensor signals to manage power supply
Solution Approach 2:
The temperature sensor acts as an intermediary between the physical temperature condition and the control circuit, providing a simple electrical signal that triggers appropriate power supply adjustments without requiring complex monitoring systems

AI summary
An endoscope provides a connector substrate of an endoscope connector to be connected to a processor with a temperature sensor for directly measuring a temperature of the connector substrate, performs control to restrict a power supply (in other words, limit and stop a power supply) from an endoscope power supply circuit according to the measured temperature of the connector substrate (in other words, the endoscope connector), and thereby appropriately manages the temperature of the endoscope connector in the endoscope.
