Profile Frame Insulating Bars with Diverging Struts for Sliding Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing composite profile frame systems for sliding elements, such as sliding doors and windows, face challenges in maintaining thermal separation between inner and outer profiles while supporting heavy multiple glazings without increasing design height, often leading to thermal bridges and undesirable protrusions.
Innovation Solution
A profile frame system using a one-piece plastic insulating support bar with diverging support struts and a snap-in geometry, combined with a metal runner, effectively distributes the weight of heavy sliding elements, maintaining thermal separation and a low design height by integrating the runner below the frame profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional metallic support and stiffening profiles are provided in the bond between frame profiles to support heavy multiple glazings, then the load-bearing capacity is improved, but the thermal separation between outer and inner profiles is lost partially and the design height increases
Solution Approach 1:
The patent introduces a plastic insulating support bar as an intermediary element between the inner and outer metallic frame profiles. This plastic bar serves as a thermal break (mediator) that prevents direct thermal contact between the metallic profiles, while still providing the necessary structural support for heavy multiple glazings through its reinforced design with integrated metal profiles.
Solution Approach 2:
The patent employs a composite structure where a plastic insulating support bar is combined with integrated metal profiles (such as aluminum) within the same component. This composite design allows the plastic portion to provide thermal insulation while the metal portions provide structural strength, eliminating the need for separate metallic support profiles that would create thermal bridges.
2Strength
If additional metallic support and stiffening profiles are provided to support heavy multiple glazings, then the load-bearing capacity is improved, but the design height of the composite profiles increases
Solution Approach 1:
The patent merges the functions of thermal insulation, structural support, and stiffening into a single integrated plastic insulating support bar with embedded metal profiles. This consolidation eliminates the need for multiple separate components (insulating bars plus additional metallic support profiles), thereby maintaining a compact design height while providing adequate load-bearing capacity for heavy multiple glazings.
3Object-affected harmful factors
If a plastic insulating support bar is used to maintain thermal separation, then thermal bridge is prevented, but the load-bearing capacity is insufficient for heavy multiple glazings
Solution Approach 1:
The patent creates a composite insulating support bar where plastic material provides thermal insulation properties to prevent thermal bridges, while integrated metal profiles (such as aluminum) embedded within the plastic provide the necessary load-bearing capacity and stiffening to support heavy multiple glazings up to 2000 kg.
Solution Approach 2:
The insulating support bar is segmented into different functional zones: plastic portions that provide thermal insulation and prevent thermal bridges, and integrated metal profile portions that provide structural strength and load-bearing capacity. This segmentation allows each material to perform its optimal function within the same component.

AI summary
A profile frame system for sliding elements includes a first and second metallic frame profiles, a one-piece insulating support bar made of plastic with a first upper bar plane and a second lower bar plane parallel to the first bar plane. Each bar plane has, on both longitudinal sides, roll-in heads rolled into respective grooves in the first and the second frame profile and thus connect the two frame profiles, wherein in the insulating support bar above the first upper bar plane a snap-in geometry oriented on the longitudinal side is provided, in which a runner is snapped-in. The first upper bar plane is connected to the second lower bar plane with two support struts. These support struts are arranged to diverge from one another at an acute angle α, starting from the snap-in geometry in the first upper bar plane and extending towards the second lower bar plane.
