Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the effective power supplied to the external load is increased, then the power generation efficiency improves, but the power distributed to the cooling device decreases, deteriorating the cooling efficiency
Solution Approach 1:
The patent implements dynamic power distribution adjustment based on real-time monitoring of cooling device performance. The control device dynamically adjusts the power distribution between the external load and cooling device to maintain optimal cooling efficiency while maximizing power generation, transforming the static power distribution into a dynamic adaptive system.
Solution Approach 2:
The control device monitors the state of the cooling device and uses this feedback information to adjust the power distribution. This closed-loop feedback mechanism ensures that the power distributed to the cooling device is sufficient to maintain effective cooling, preventing the deterioration of cooling efficiency that would otherwise occur when power is prioritized for external load.
2Power
If the power distributed to the fan is reduced, then more power is available for the external load, but the temperature difference between heat receiver and heat dissipater decreases
Solution Approach 1:
The system monitors and adjusts power distribution parameters based on the actual cooling performance. By changing the power allocation parameters dynamically rather than using fixed allocation, the system maintains the temperature difference necessary for efficient thermoelectric power generation while maximizing the power available for external load.
