Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface temperature control systems for building ceilings, walls, and floors are not flexible enough for easy assembly and require precise installation, leading to inefficiencies in heat transfer due to limited contact area between pipes and thermally conductive materials.
Innovation Solution
A surface temperature control system featuring an installation board with pipe routing channels and overlapping thermally conductive foils that are easily applied to create a large contact area, allowing for flexible handling and simple assembly, with the foils being pressed into the channels during pipe insertion to enhance heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single thermally conductive foil is used to cover the pipe guide channel, then the assembly process becomes more complex due to the need for precise lamination, but the contact area with the pipe is maximized
Solution Approach 1:
The single thermally conductive foil is divided into two separate foils that are applied to opposite sides of the pipe guide channel. This segmentation reduces the lamination precision requirement for each individual foil while collectively providing comprehensive thermal contact with the pipe when the foils are pressed together during pipe insertion.
2Loss of energy
If the thermally conductive foils are pressed firmly into the pipe guide channel to maximize heat transfer, then the heat transfer efficiency improves, but the assembly effort and difficulty increase
Solution Approach 1:
The pipe insertion process itself serves to press the thermally conductive foils into the pipe guide channel. As the pipe is inserted, it automatically compresses the foils against the channel walls, eliminating the need for separate pressing operations and reducing assembly effort while ensuring adequate thermal contact.
3Manufacturing precision
If the thermally conductive foils are made to completely cover the pipe guide channel to ensure uniform lining, then the heat transfer uniformity improves, but the material consumption and cost increase
Solution Approach 1:
The thermally conductive foils are applied selectively to specific areas of the pipe guide channel rather than completely covering it. The foils are positioned to provide thermal contact where most needed, with the overlapping arrangement ensuring adequate coverage and uniformity while reducing overall material consumption compared to complete channel lining.

Function Achieved in This Case
This solution enables efficient heat transfer with reduced assembly effort, compensates for lamination tolerances, and allows for customizable coverage of pipe areas, maintaining high efficiency in heating and cooling without the cost disadvantages of fully lined systems.
