Thermally Separated Profile Shell for Warping Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile assemblies for door systems fail to effectively separate interior and exterior rooms thermally while preventing bending and warping of the profile frame due to temperature differences, which can lead to material tension and potential warping of the frame.
Innovation Solution
A profile assembly is developed with a vertical profile element divided into two thermally separated shell parts connected via an insulating element, allowing for thrust-flexible connections to accommodate expansion and prevent warping, and a horizontal profile element also divided into shell parts for enhanced thermal separation and stability, using sheet steel connectors and plastic or composite insulating materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If profile elements are made as single integrated shells, then structural strength is improved, but thermal separation between interior and exterior sides deteriorates
Solution Approach 1:
The profile shell is divided into first and second profile shell parts (interior and exterior sides) that are thermally separated by an insulating element while remaining structurally connected through the profile connecter element, achieving both thermal separation and structural strength
2Stability of the object's composition
If profile elements are rigidly fixed to prevent movement, then structural stability is improved, but thermal expansion compensation deteriorates
Solution Approach 1:
The connection between profile shell parts is made thrust-flexible rather than rigid, allowing the exterior profile shell part to move freely in the axial direction to compensate for thermal expansion while maintaining structural stability through the insulating element connection
3Strength
If vertical profiles are used to provide structural support, then mechanical strength is improved, but material tension and warping increase due to temperature differences
Solution Approach 1:
The vertical profile is divided into interior and exterior profile shell parts separated by an insulating element, allowing differential thermal expansion without generating harmful tensions that cause warping, while maintaining mechanical strength through the profile connecter element
Solution Approach 2:
The connection between profile shell parts is designed with specific mechanical properties (thrust-flexible) that allow thermal expansion while maintaining structural integrity, changing the mechanical parameters to accommodate thermal stresses
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides effective thermal separation and prevents warping by allowing for unhindered expansion of the profile elements, ensuring stability and cost advantages through reduced part differentiation, while maintaining structural integrity and thermal insulation.
Implementation Method 1
the profile shell parts are connected to each other, thermally separated from each other, via at least one insulating element (e.g. insulating profile, or web)
Implementation Method 2
based on temperature differences between interior room and exterior room, compensates for arising material tensions (which are caused by surface ratios primarily by the vertical profiles)

AI summary
A profile assembly includes two profile elements, a profile connecter element, and at least one fastening element connecting the two profile elements to each other using the profile connecter element. The first profile element includes guide channels for receiving two leg parts of the profile connecter element. The first profile element includes at least one fastening channel for receiving the fastening element. The second profile element includes a U-shaped recess for receiving the profile connecter element. In the base, the profile connecter element and second profile element in the bottom of the U-shaped recess thereof respectively include at least one mounting opening corresponding to the fastening channel for passing the fastening element there-through. At least the second profile element is formed in several parts and includes two shell parts in the direction of interior and exterior rooms. The profile shell parts are connected to each other, yet thermally insulated.
