Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate heat storage apparatuses are used for heat sources with different temperatures, then each heat source can be stored independently, but the system complexity and space requirements increase
Solution Approach 1:
The patent combines multiple heat storage tanks with different temperature storage capabilities into a single integrated system. The system includes a first heat storage tank for high-temperature heat storage and a second heat storage tank for low-temperature heat storage, both managed by a unified control device that coordinates heat source selection, pump operation, and valve control to achieve reliable heat storage without requiring completely separate apparatuses for each temperature level
2Device complexity
If a single heat storage apparatus is used, then the system is simpler, but it cannot effectively store heat sources with different temperatures
Solution Approach 1:
The patent segments the heat storage function into multiple specialized tanks: a first heat storage tank for high-temperature heat storage and a second heat storage tank for low-temperature heat storage. Each tank is optimized for specific temperature ranges, allowing the system to effectively store heat sources with different temperatures while maintaining manageable complexity through modular design and unified control
3Productivity
If heat is recovered from the heat storage apparatus, then heat utilization is improved, but the tank temperature decreases over time resulting in non-uniform temperature distribution
Solution Approach 1:
The patent implements a control device that continuously monitors temperatures in both heat storage tanks and dynamically adjusts the system operation. The control device selects appropriate heat sources, operates pumps and valves to maintain temperature distribution, and coordinates between the first and second heat storage tanks to ensure uniform temperature output during heat recovery, preventing temperature degradation over time
