Insulating Glass Spacer Strand Bending for Glazing Bar Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling insulating glass panes with glazing bars often result in a wavy spacer and require additional components like glazing bar holders, which complicates the assembly process and affects the visual appeal of the panes.
Innovation Solution
The method involves applying a pasty and subsequently solidifying spacer strand to a glass sheet, bending it outward to increase the internal dimension, and then embedding the glazing bar ends directly into the spacer strand, which is then bent back to its original shape, securing the glazing bar insert without the need for additional holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glazing bar ends are pressed into the spacer strand, then the glazing bar insert is securely fixed, but the spacer becomes wavy and deformed
Solution Approach 1:
The spacer strand is bent outward before glazing bar insertion to create expanded internal dimensions. This preliminary deformation provides sufficient space for the glazing bar ends to be embedded without causing waves or deformations in the final spacer structure.
Solution Approach 2:
The spacer strand undergoes dynamic deformation - being bent outward during insertion, then bent back to its original shape after the glazing bar is positioned. This allows temporary expansion for insertion followed by recovery to maintain structural integrity.
2Reliability
If glazing bar holders are used to secure glazing bars, then the glazing bars are stable, but the assembly process becomes more complex
Solution Approach 1:
The glazing bar holder component is completely removed from the assembly. Instead of using separate holders, the glazing bar ends are directly embedded into the spacer strand, eliminating the need for additional securing components and simplifying the assembly process.
Solution Approach 2:
The function of the glazing bar holder is merged into the spacer strand itself. The spacer strand directly performs the securing function by embedding the glazing bar ends, combining the spacer and holder functions into a single integrated component.
3Area of stationary object
If the spacer internal dimension is increased to accommodate glazing bars, then the glazing bars can be inserted, but the spacer requires additional bending operations
Solution Approach 1:
The spacer strand is bent outward in a controlled preliminary action before insertion to create the necessary internal space. This predetermined deformation ensures the glazing bar can be inserted without requiring complex adjustments or multiple bending operations.

AI summary
An insulating glass pane has at least two glass sheets, a frame-shaped spacer and a glazing bar insert, as well as a method and a device for their manufacture. The glazing bar insert is mounted inside the spacer between the two glass sheets. The glazing bar insert includes at least one elongated glazing bar profile with a glazing bar end facing the spacer. At least one glazing bar end is formed by a glazing bar profile being formed as hollow profile and is embedded in the plastic-based material of the spacer in such a way that part of the plastic-based material is present in the interior of the hollow profile.
