Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If flat, flexible absorber mats are installed in the ground, then heat transfer surface area is increased, but installation area projected onto the earth's surface becomes very large
Solution Approach 1:
The patent transitions from a two-dimensional flat absorber mat layout to a three-dimensional coiled configuration. The heat transfer element is arranged in a coiled form with multiple loops stacked vertically within a confined ground area, thereby increasing the heat transfer surface area while minimizing the projected installation area onto the earth's surface.
Solution Approach 2:
The coiled heat transfer element is nested within a vertical borehole or confined space in the ground. Multiple loops of the coil are stacked one inside another, similar to nested dolls, allowing the heat transfer surface to be packed into a small footprint area while maintaining extensive surface area for heat exchange.
2Area of stationary object
If heat transfer elements are coiled to reduce installation area, then space requirement is reduced, but heat transfer efficiency is significantly reduced
Solution Approach 1:
The coiled heat transfer element is divided into multiple separate loops or segments. Each loop acts as an independent heat transfer zone, ensuring that heat transfer occurs at multiple discrete locations rather than along a continuous path. This segmentation maintains heat transfer efficiency by reducing thermal interference between adjacent sections of the coil.
Solution Approach 2:
The heat transfer element is formed into a coiled or spiral curved configuration rather than a straight line. This curvature allows the element to pack efficiently into a small ground area while maintaining sufficient surface area exposure to the surrounding ground for effective heat exchange, optimizing both space utilization and heat transfer performance.
3Ease of operation
If plastic hoses are woven into knitted fabric for heat transfer, then flexibility and installation ease are improved, but large surface area is required when flat
Solution Approach 1:
The flexible plastic hose is transformed from a flat linear arrangement into a three-dimensional coiled structure. The flexibility of the plastic hose enables it to be bent and coiled without damage, and this coiled configuration allows the same length of hose to occupy much less projected area on the ground surface while maintaining its heat transfer functionality.
