Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temperature sensor with long pins is used to monitor cooling fluid temperature in the cold plate, then the sensor can be connected to the circuit board, but the assembly process becomes complex and requires protective sleeves
Solution Approach 1:
The patent extracts the temperature sensing function from the main cold plate body by adding a protruding part. This protruding part extends from the cold plate and provides a dedicated location for the temperature sensor, allowing the sensor to be positioned optimally for monitoring cooling fluid temperature without requiring complex connections to the circuit board through the cold plate body
Solution Approach 2:
The protruding part acts as an intermediary element between the cold plate and the temperature sensor. It provides a convenient mounting location and thermal pathway for the sensor, eliminating the need for protective sleeves and complex pin connections while maintaining reliable temperature monitoring capability
2Ease of operation
If the temperature sensor is directly connected to the circuit board through the cold plate, then temperature monitoring is achieved, but protective sleeves and complex assembly procedures are required
Solution Approach 1:
The temperature sensor is extracted from the traditional mounting location on the circuit board and repositioned on the protruding part of the cold plate. This extraction simplifies the assembly process by eliminating the need for protective sleeves and complex pin connections, while the protruding part ensures reliable thermal contact with the cooling fluid
Solution Approach 2:
Instead of mounting the temperature sensor on the circuit board and connecting it through the cold plate, the patent inverts the approach by mounting the sensor directly on the cold plate's protruding part. This inversion simplifies the assembly process and improves reliability by creating a direct thermal pathway from the cooling fluid to the sensor
