Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a current is applied to the lighting diode for testing, then light emission is generated for detection, but the temperature of the diode increases affecting measurement accuracy
Solution Approach 1:
The harmful thermal effect is extracted and separated from the testing process by introducing a cooling fluid through nozzles to remove heat from the diode during current application, allowing light detection to proceed without temperature interference
Solution Approach 2:
A cooling fluid is introduced as an intermediary substance between the diode and the testing environment, absorbing excess heat and transferring it away to maintain stable operating conditions during light emission detection
2Temperature
If cooling fluid is directed towards the lighting diode, then temperature control is improved, but device complexity increases
Solution Approach 1:
A fluid delivery system using nozzles is employed to direct cooling fluid onto the diode, providing effective thermal management through hydraulic means while maintaining a relatively simple system architecture
Solution Approach 2:
The cooling fluid system serves multiple functions: it cools the diode during testing, maintains stable operating conditions, and enables accurate light detection, making the added complexity worthwhile through multi-functional benefits
