Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heat exchanger with internally flowing heat transfer medium is used, then heat transfer between storage medium and consumer is achieved, but device complexity and maintenance effort increase
Solution Approach 1:
The invention extracts the heat transfer medium and internal flow paths from the heat exchanger, replacing them with direct solid body contact between the storage medium and the heat transfer solid body. This eliminates the complex internal circuitry while maintaining heat transfer functionality.
Solution Approach 2:
A solid body arrangement acts as an intermediary between the storage medium and the heat transfer medium. This solid body conducts heat directly from the storage medium without requiring internal flow paths, simplifying the overall system structure.
2Ease of operation
If a feed pump is used to control heat flow, then heat transfer rate can be regulated, but device complexity and maintenance effort increase
Solution Approach 1:
The invention replaces the mechanical feed pump system with a thermally conductive solid body arrangement. Heat flow is controlled by the thermal properties and contact area of the solid body rather than mechanical pumping, eliminating the need for pump management.
Solution Approach 2:
The solid body arrangement naturally conducts heat from the storage medium to the heat transfer medium based on temperature gradients and contact area, providing self-regulating heat flow control without requiring external mechanical intervention.
3Reliability
If a heat exchanger with internal circuits is used, then heat transfer is achieved, but maintenance effort increases
Solution Approach 1:
The invention removes the internal circuits and heat transfer medium from the heat exchanger, replacing them with a solid body contact system. This eliminates the complex internal components that require maintenance while preserving heat transfer capability.
Solution Approach 2:
The solid body arrangement can be designed as a simple, replaceable component with no moving parts or internal circuits, making it extremely easy to maintain or replace if needed, effectively eliminating maintenance complexity.
