Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple heat dissipation fans are arranged to dissipate heat more effectively, then heat dissipation effect is improved, but noise and power consumption increase
Solution Approach 1:
The patent implements a movable heat dissipation fan that can dynamically change its position based on real-time temperature monitoring of different display regions. The fan moves to the region with the highest temperature, allowing a single fan to effectively cool multiple different hot spots sequentially, thereby reducing the total number of fans needed and lowering noise and power consumption while maintaining effective heat dissipation
Solution Approach 2:
The single heat dissipation fan serves multiple functions by being able to cool different display regions at different times. Through the movement mechanism, one fan replaces multiple stationary fans, each dedicated to a specific region, making the fan system universal and adaptable to various heat generation patterns
2Temperature
If multiple heat dissipation fans are arranged to dissipate heat more effectively, then heat dissipation effect is improved, but power consumption increases
Solution Approach 1:
The system uses a single fan with movement capability instead of multiple stationary fans. The fan is controlled to operate only when and where needed based on temperature monitoring, reducing overall power consumption while maintaining effective cooling through strategic positioning at hot spots
Solution Approach 2:
The patent extracts the essential cooling function from multiple fans and concentrates it into a single movable fan unit. By taking out the movement capability and control system, the design achieves the same cooling effect with fewer components, thereby reducing power consumption
3Measurement precision
If temperature monitoring and movement control are added, then heat dissipation precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical multi-fan systems with a simpler single-fan system controlled by electronic temperature monitoring and movement mechanisms. The electronic control system integrates temperature detection, region analysis, and fan positioning into a unified control architecture that is easier to manufacture and maintain than multiple independent fan assemblies
