Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat pump is used to transfer heat from the local cooling system to the local heating system, then the overall energy consumption is reduced, but the device complexity increases
Solution Approach 1:
The heat pump merges the cooling and heating systems into a single integrated thermal management system. By combining the cooling system (with cooling circuit and cooler) and heating system (with heating circuit and heater) into one system that shares the heat pump component, the patent enables heat transfer between the two systems, reducing overall energy consumption while managing the complexity through unified control based on determined energy consumption needs.
2Use of energy by moving object
If the heat pump transfers heat from the cooling system to the heating system, then the energy drawn from both heating and cooling grids is reduced, but the control complexity increases
Solution Approach 1:
The control system implements feedback by continuously determining the energy consumption needs of both the cooling system and heating system, then using this information to dynamically control the heat pump operation. This feedback loop ensures that the heat pump transfers heat optimally between systems based on actual needs, reducing energy drawn from external grids while managing control complexity through demand-responsive operation.
3Reliability
If simultaneous cooling and heating needs are met using separate systems, then the reliability is maintained, but the energy efficiency deteriorates
Solution Approach 1:
The patent converts the previously wasted heat from the cooling system into a beneficial resource for the heating system. By capturing and transferring the heat that would otherwise be discarded during cooling operations to meet heating needs, the system maintains reliable supply to both systems while dramatically improving energy efficiency and reducing overall energy consumption.
