Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed flow path is engineered for coolant transmission, then thermal coupling between coolant and circuitry is optimized for predefined usage scenarios, but cooling effectiveness deteriorates when device orientation or usage conditions change
Solution Approach 1:
The patent implements multiple coolant flow paths with dynamically selectable configurations. Instead of a single fixed flow path, the system provides several predefined flow paths (first flow path, second flow path, etc.) that can be selectively activated based on device orientation and thermal conditions. The control system dynamically switches between these flow paths to maintain optimal cooling effectiveness across varying usage scenarios and orientations.
Solution Approach 2:
The system changes operational parameters by selecting different flow path configurations based on detected device orientation and thermal conditions. The control system monitors orientation parameters and thermal parameters, then adjusts the coolant flow path selection to optimize cooling performance for each specific condition, effectively adapting the thermal management system to different operational states.
2Adaptability or versatility
If multiple flow paths are provided for different orientations, then adaptability to various usage scenarios is improved, but device complexity increases
Solution Approach 1:
The cooling system is segmented into multiple discrete flow path configurations, each optimized for specific orientation scenarios. Rather than attempting to create a single complex adaptive system, the patent divides the cooling function into separate, manageable flow path segments that can be independently controlled and switched between based on operational conditions.
Solution Approach 2:
The control system serves multiple functions by selecting from different flow path configurations. A single control system handles orientation detection, thermal monitoring, and flow path selection, making the system multi-functional and reducing the need for separate dedicated systems for each cooling scenario.
3Use of energy by moving object
If coolant flow is impelled along suboptimal flow paths, then power consumption and noise are reduced, but cooling effectiveness deteriorates
Solution Approach 1:
The control system continuously monitors thermal conditions and device orientation, using this feedback information to dynamically select the most appropriate flow path configuration. This feedback mechanism ensures that coolant is directed along the most effective flow path for current conditions, optimizing the balance between cooling performance and energy consumption.
Solution Approach 2:
The system dynamically adjusts coolant flow path selection based on real-time thermal and orientation conditions. Rather than operating at fixed performance levels, the system adapts its cooling strategy to match actual thermal demands, reducing power consumption when full cooling capacity is not required while maintaining adequate cooling effectiveness.

AI summary
A method for cooling an electronic device having first and second flow paths for transmitting a coolant. The method includes assessing a merit of impelling the coolant along the first flow path relative to impelling the coolant along the second flow path. When the relative merit is above a threshold, coolant is impelled along the first flow path. When the relative merit is below the threshold, coolant is impelled along the second flow path.
