Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional solar thermal systems are used with separate components, then system functionality is achieved, but system complexity and installation costs increase
Solution Approach 1:
The patent combines the thermal storage element and solar thermal collector into a single integrated module. The collector is positioned directly on the thermal storage element, creating a unified system that eliminates separate installation steps and reduces overall system complexity while maintaining all necessary functionalities.
Solution Approach 2:
The integrated module serves multiple functions simultaneously: the thermal storage element provides heat storage capacity, the collector captures solar energy, and the combined structure can be directly installed on building surfaces. This multi-functionality reduces the number of separate components needed and simplifies the overall system.
2Adaptability or versatility
If multiple separate solar thermal components are installed, then all required functions are achieved, but planning and implementation effort increases
Solution Approach 1:
By merging the collector and thermal storage element into one pre-assembled module, the patent eliminates the need for separate planning and installation of individual components. The integrated design allows for streamlined procurement, simplified installation procedures, and reduced on-site assembly time.
3Reliability
If conventional thermal storage elements are used, then heat storage capacity is achieved, but integration into building structures with special static requirements becomes difficult
Solution Approach 1:
The thermal storage element is designed to serve dual purposes: providing heat storage capacity while also functioning as a structurally suitable component for integration into various building structures. The element can be adapted to different static requirements, including load-bearing walls and non-load-bearing structures, enhancing its versatility for building integration.
