Vehicle Glass Edge Profile With Integrated Distance Pieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bonding glass panes to vehicle frames require individual adhesive bonding of distance pieces, which is costly and prone to handling and assembly issues, particularly with small bonding areas and potential tilt loading.
Innovation Solution
An edge profile with integrally formed or attached distance pieces, produced via extrusion, which defines the glass pane's installation position relative to the vehicle frame, eliminating the need for individual adhesive bonding and reducing assembly effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual distance pieces are adhesively bonded to the glass pane, then the glass pane can be positioned correctly in its installation position, but the mounting process becomes costly and complex with handling and assembly issues
Solution Approach 1:
The patent combines multiple individual distance pieces into a single integrated edge profile structure that runs along the glass pane edge. This merging eliminates the need for separate adhesive bonding operations for each distance piece, reducing mounting complexity while maintaining precise positioning through the continuous profile structure
Solution Approach 2:
The distance pieces are pre-positioned and integrated into the edge profile during manufacturing rather than being individually bonded during assembly. This preliminary action ensures correct positioning is built into the structure itself, eliminating the need for complex assembly operations and reducing handling requirements
2Measurement precision
If multiple individual distance pieces are bonded separately, then the glass pane positioning can be achieved, but the adhesive bonding process becomes expensive and time-consuming
Solution Approach 1:
Multiple distance pieces are merged into a single continuous edge profile that can be installed in one operation rather than requiring multiple separate bonding operations. This dramatically increases productivity while maintaining the precise positioning function through the integrated structure
Solution Approach 2:
The edge profile provides continuous positioning support along the glass pane edge rather than discrete intermittent bonding points. This continuous structure enables faster installation while ensuring consistent positioning accuracy throughout the entire edge
3Reliability
If individual distance pieces are adhesively bonded, then the glass pane can be secured to the vehicle frame, but handling and assembly issues arise particularly with small bonding areas and tilt loading
Solution Approach 1:
Multiple small bonding areas are merged into a single continuous bonding interface along the edge profile. This eliminates handling issues associated with small discrete bonding areas and distributes loads more evenly, preventing tilt loading while maintaining bonding reliability
Solution Approach 2:
The edge profile acts as a flexible continuous element that can accommodate slight misalignments and distribute forces evenly along its length, preventing the tilt loading that occurs with rigid discrete bonding points while maintaining secure attachment
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 edge profile significantly simplifies the mounting process, reduces handling effort, and prevents issues like tilt loading, while ensuring precise positioning and consistent spacing between the glass pane and vehicle frame.
Implementation Method 1
The invention furthermore relates to a method for producing such an edge profile, which can be attached to a pane edge of a glass pane of vehicle glazing, by extruding a plastics compound

AI summary
An edge profile of a glass pane of vehicle glazing, wherein the edge profile may have a plurality of distance pieces, which are arranged at a distance from one another along the edge profile, and that the edge profile attached to a pane edge defines with the distance pieces an installation position of the glass pane relative to a vehicle frame carrying the glass pane.
