Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling fan is used to control the temperature of the light source, then the temperature can be maintained, but the responsiveness is slow and a long time is required until the temperature changes
Solution Approach 1:
The patent combines both a heater and a cooling fan in the temperature control system. The heater is installed in contact with the lamp house to provide heating capability, while the cooling fan provides cooling capability. This merging of heating and cooling functions enables bidirectional temperature adjustment, significantly improving responsiveness when environmental temperature fluctuates rapidly.
Solution Approach 2:
The control device dynamically adjusts the output of the heater based on the detected temperature difference between the light source and the set temperature. By changing the heating power parameter in response to temperature conditions, the system achieves faster and more accurate temperature control compared to using only a cooling fan.
2Device complexity
If only a cooling fan is used for temperature control, then the structure is simple, but the temperature control range is limited particularly in low rotational speed region
Solution Approach 1:
The patent merges the heater and cooling fan into a unified temperature control system managed by a control device. This combination expands the temperature control range by providing both heating and cooling capabilities, allowing the system to adapt to various environmental conditions and maintain the light source temperature within a broader range.
Solution Approach 2:
The temperature control system is designed with multi-functionality by incorporating both heating and cooling functions. The control device can selectively activate the heater, cooling fan, or both based on the temperature conditions, making the system adaptable to diverse temperature control requirements and environments.
3Adaptability or versatility
If the environmental temperature changes rapidly, then the operating conditions vary, but the cooling fan cannot respond quickly enough causing light source temperature fluctuation
Solution Approach 1:
The control device continuously monitors the light source temperature and dynamically adjusts the heater output based on the temperature difference from the set point. This real-time parameter adjustment enables the system to rapidly respond to environmental temperature changes and maintain baseline stability.
Solution Approach 2:
The system implements feedback control by using a temperature sensor to detect the light source temperature and feeding this information back to the control device. The control device then adjusts the heater and cooling fan operations based on this feedback, ensuring stable temperature control even when environmental conditions change rapidly.
