Hinge-Clip Insulating Web for Window Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermally insulated composite profiles for windows, doors, and facade elements face challenges in manufacturability, storage, and transport due to the size and material requirements of insulating bars, which lead to increased costs and potential deformation and damage during handling.
Innovation Solution
The introduction of a hinge-clip device for insulating bars allows the crossbar to pivot and be securely held, reducing the need for large tools and packaging material, while also providing a compact design that minimizes deformation and damage during storage and transport, and allows for efficient production and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If insulating bars with transverse bars of different lengths are provided to divide the hollow chamber, then thermal separation between aluminum profiles is improved, but device complexity and material requirements increase
Solution Approach 1:
The insulating bar is segmented into a body and an integrated hinge-clip device with transverse web, allowing the hollow chamber to be divided into multiple compartments. This segmentation provides thermal separation between aluminum profiles while keeping the overall structure compact and manageable.
Solution Approach 2:
The hinge-clip device merges multiple functions into a single integrated component: the transverse web divides the hollow chamber for thermal separation, the hinge mechanism enables compact storage, and the clip connection provides structural support. This reduces the need for separate components and simplifies the overall design.
2Temperature
If insulating bars with transverse bars of different lengths are provided, then thermal separation is improved, but manufacturing complexity and tool requirements increase
Solution Approach 1:
The hinge-clip device serves multiple functions: the transverse web divides chambers for thermal isolation, the hinge mechanism enables compact storage and transport, and the clip connection provides structural support. This multi-functionality reduces the need for different types of tools and simplifies manufacturing processes.
3Temperature
If insulating bars with transverse bars of different lengths are provided, then thermal separation is improved, but packaging material and storage capacity requirements increase
Solution Approach 1:
The hinge mechanism transforms the insulating bar from a rigid structure to a dynamic one that can be folded or collapsed. The transverse web can be rotated relative to the insulating bar body, allowing compact storage and transport while maintaining the thermal separation function when in use.
4Temperature
If insulating bars with transverse bars of different lengths are provided, then thermal separation is improved, but deformation and damage during packaging, storage and transport increase
Solution Approach 1:
The hinge mechanism allows the transverse web to be rotated into a protective position during storage and transport, reducing the risk of deformation and damage. The dynamic structure can be collapsed or folded to minimize exposure to external forces while maintaining structural integrity.
Solution Approach 2:
The hinge-clip device design inherently protects the transverse web from damage during handling. The hinge mechanism allows the transverse web to be positioned in a protected state during transport, preventing deformation before damage can occur.

Function Achieved in This Case
This solution simplifies and cost-reduces the manufacturability and transportability of insulating bars, reducing material needs and storage requirements, while maintaining effective thermal separation between aluminum profiles through the use of swiveled-in transverse webs and foam bodies.
Implementation Method 1
A hinge (43) is formed at an end (40a) of the first projection (40). The hinge (43) has a pivot axis (S) parallel to the longitudinal direction (Z), so that a first hinge side (43a) and a second hinge side (43b) of the hinge (43) can be pivoted about the pivot axis (S) relative to one another
Implementation Method 2
A first clip part (46) of a clip connection (44) is connected to the first projection (40) via the hinge (43). A second clip part (45) of the clip connection (44) is provided at one end (41a) of the second projection (41)
Implementation Method 3
The web (33) is deformed by plastic deformation by rollers (not shown) from the position shown in solid lines into the position shown in dashed lines (=rolling in)
Implementation Method 4
Two aluminum profiles (31, 32) are connected to one another by two insulating bars (10) and are thermally separated from one another

AI summary
An insulating web (10) for a composite profile for window, door or façade elements is specified in which a functional part (21) in the form of a transverse web is connected via a hinge-clip device, which has a clip connection (44), to a web body (20) of the insulating web (10) in such a way that, in a closed state of the clip connection (44), the functional part (21) extends away from the hinge (43) along a height direction (Y).
