Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light source unit is disposed as an independent part not temperature-controlled, then there is good workability for replacing a light source, but the light quantity becomes unstable due to temperature fluctuations
Solution Approach 1:
The device is divided into independent functional modules: the light source unit can be replaced independently while the temperature control system remains separate but connected via thermal coupling. This segmentation allows easy replacement of the light source while maintaining the temperature control capability through the thermal coupling mechanism.
Solution Approach 2:
A temperature control unit acts as an intermediary between the external environment and the light source unit. This intermediary controls the temperature of the base and substrate, stabilizing the light source operating conditions without requiring the entire light source assembly to be temperature-controlled, thus maintaining both replaceability and stability.
2Device complexity
If the light source is exposed to outside air, then the structure is simple, but the stabilization time becomes long when outside air temperature is low
Solution Approach 1:
The temperature control unit pre-heats or pre-cools the base and substrate to the target operating temperature before the light source is activated. This preliminary temperature adjustment reduces the stabilization time when the device is powered on, especially in environments with low outside air temperature, while maintaining relatively simple structural design.
3Device complexity
If the light source is exposed to outside air, then the structure is simple, but the light quantity fluctuates when outside air temperature fluctuates
Solution Approach 1:
The temperature control unit serves as a buffer between external temperature fluctuations and the light source. It actively compensates for outside air temperature changes by adjusting the heating or cooling applied to the base and substrate, thereby maintaining consistent light source operating temperature and stable light output despite external temperature variations.
Solution Approach 2:
The system dynamically adjusts the temperature control parameters (heating power, cooling rate) based on detected temperature changes in the base and substrate. This parameter adjustment ensures the light source operates at a stable temperature, maintaining consistent light quantity even when outside air temperature fluctuates, without requiring complex structural modifications.
