Thermally Separated Profile Assembly for Corner Joint Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile arrangements do not guarantee complete thermal insulation between interior and exterior spaces, particularly at corners, due to the use of metallic profile connectors, which compromise thermal separation.
Innovation Solution
A profile arrangement with two thermally separated profile connector elements, spaced apart along a connecting line between interior and exterior spaces, and insulating elements with displaceable webs to ensure a shear-free connection, minimizing thermal conductivity and warping effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic profile connectors are used to connect horizontal and vertical profile elements, then structural strength and connection stability are improved, but thermal insulation performance deteriorates due to thermal bridges at corners
Solution Approach 1:
The connection system is divided into separate functional components: profile connector elements for mechanical connection and insulating elements for thermal isolation. The insulating elements are positioned between the inner and outer profile shell parts, segmenting the thermal path while the connector elements maintain structural integrity through spaced-apart positioning along the connecting line.
Solution Approach 2:
Insulating elements serve as intermediary components between the metallic profile connector elements and the profile shell parts. These intermediaries break the thermal bridge path while allowing the metallic connectors to maintain their mechanical function, effectively decoupling thermal and structural requirements.
2Object-affected harmful factors
If insulating elements with displaceable webs are used to ensure shear-free connection, then thermal insulation is improved, but structural stability may deteriorate due to potential warping under temperature variations
Solution Approach 1:
The insulating elements incorporate displaceable webs that can move relative to each other in the longitudinal direction, allowing the connection to adapt dynamically to thermal expansion and contraction. This dynamic capability enables the structure to maintain both insulation and stability by accommodating dimensional changes without compromising either function.
Solution Approach 2:
The displaceable webs change their position and deformation state in response to temperature variations, allowing the insulating elements to maintain optimal insulation performance while accommodating thermal stresses. The ability to change geometric parameters under load prevents warping and maintains structural integrity.

Implementation Method 1
the horizontal profile shell parts are thermally separated from one another via a horizontal insulating element, a vertical profile element... wherein the vertical profile shell parts are thermally separated from one another and connected to one another via a vertical insulating element
Implementation Method 2
Door leaves, etc., generally deform when the temperature outside differs significantly from that inside, such as in strong sunlight or freezing conditions. Consequently, the door jams or becomes difficult to open and close.
