Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building components, particularly windows and doors, face significant thermal energy loss due to conduction, convection, and radiation, leading to inefficient energy use and increased heating costs, as existing insulation methods struggle to effectively reduce conductive heat transfer across thermally conductive materials.
Innovation Solution
A thermal bridge system comprising a body region and fingers inserted into channels with locking tabs, which are secured using an assembly jig to reduce conductive heat transfer between retention members, utilizing non-thermally conductive materials like PVC or plastic to minimize heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing insulation methods are used, then thermal energy loss is reduced to some extent, but conductive heat transfer across thermally conductive materials remains significant
Solution Approach 1:
The thermal bridge is divided into multiple segments including a first retention member, a second retention member, and an insulating member positioned between them. This segmentation creates discrete thermal barriers that collectively reduce conductive heat transfer while maintaining structural integrity.
Solution Approach 2:
An insulating member is introduced as an intermediary element between the first and second retention members. This intermediary component specifically targets conductive heat transfer by providing a thermal barrier that prevents direct thermal contact between thermally conductive materials.
2Strength
If locking tabs are closed to secure the thermal bridge, then the thermal bridge is firmly attached, but the channels may deform during the closing process
Solution Approach 1:
The assembly jig is used to pre-position and align the first and second retention members before the locking tabs are closed. This preliminary alignment action ensures that the channels are properly positioned relative to each other, preventing deformation during the subsequent closing operation.
Solution Approach 2:
The assembly jig acts as an intermediary tool that facilitates the closing process. It provides mechanical support and alignment guidance during tab closure, distributing forces evenly and preventing channel deformation while ensuring firm attachment of the thermal bridge.
3Strength
If thermally conductive materials are used for structural members, then structural strength is maintained, but heat transfer efficiency decreases
Solution Approach 1:
The thermal bridge structure employs local quality by using thermally conductive materials (such as aluminum or stainless steel) for the retention members where structural strength is required, while simultaneously incorporating an insulating member in the specific location where heat transfer occurs. This localized differentiation of material properties allows the structure to maintain strength while reducing thermal conductivity at critical interfaces.
Solution Approach 2:
The thermal bridge assembly functions as a composite structure combining thermally conductive retention members with a thermally insulating member. This composite approach leverages the complementary properties of different materials: the conductive materials provide structural integrity while the insulating material reduces heat transfer, achieving both strength and thermal efficiency.
