Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding frame devices with insulating bars made of poorly conductive materials face issues with heat transfer, structural depth, visibility, mechanical exposure, and UV sensitivity, leading to inefficiencies in energy efficiency and security.
Innovation Solution
Incorporating a retaining profile attached to an integrally formed fastening element on the insulating strip, which supports wing elements and reduces the gap between them, while providing protection and UV resistance by covering the insulating strip, allowing for surface treatment and improved cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If insulating bars are made with minimum length to reduce heat transfer, then thermal insulation is improved, but the structural depth of the frame device increases and the gap between wing elements increases
Solution Approach 1:
The receiving profile is divided into two parts: a first receiving profile part formed on the frame profile and a second receiving profile part formed on the insulating bar. This segmentation allows the insulating bar to be shorter while still providing sufficient support for the wing element, thereby reducing structural depth without compromising thermal insulation.
Solution Approach 2:
The second receiving profile part is integrated into the insulating bar, nesting the support function within the insulating component itself. This eliminates the need for a separate extended receiving structure, reducing overall structural depth while maintaining thermal break effectiveness.
2Length of stationary object
If insulating bars are made visible and freely accessible, then the gap between wing elements is reduced, but mechanical protection and security are worsened
Solution Approach 1:
A covering profile is introduced as an intermediary element that covers the insulating bar. This covering profile acts as a mediator that maintains the reduced gap appearance while simultaneously providing mechanical protection and preventing direct access to the insulating bar, thereby addressing security concerns.
3Ease of manufacture
If insulating bars are made of plastic material for ease of manufacture, then manufacturing is improved, but surface treatment and UV resistance are worsened
Solution Approach 1:
The solution uses a composite structure where the insulating bar remains plastic for ease of manufacture, but is combined with a covering profile that provides UV resistance and surface treatment capabilities. This composite approach allows each material to contribute its strengths: plastic for manufacturing ease and metal/coated material for durability and aesthetics.
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
This configuration reduces the gap between wing elements, enhances mechanical and UV protection, and improves the appearance and durability of the insulating strip, thereby increasing energy efficiency and security.
Implementation Method 1
the metallic frame profiles on which the receiving profiles for the leaf elements are formed are connected to one another by insulating bars in known sliding frame devices of the generic type. Due to the fact that these insulating bars are made of a poorly thermally conductive material, they prevent the transfer of heat through thermal conduction between the two frame profiles.

AI summary
The sliding frame device (100) comprises a primary frame profile (101) and a secondary frame profile (102), which are connected by an insulating web (103). The insulating web comprises a fastening element (105) for fastening a third profile, which is formed as a holding profile (150) made of aluminum. The holding profile interacts with a holding element (152), such that the holding profile and the holding element support a wing (110), particularly a window or door wing.
