Pivoting Cursor Assembly for Frameless Glass Stiffness Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frameless window systems in vehicles face limitations in stiffness, require costly tools and components, and can adversely affect glass system deflection due to adjustments made on the regulator rails, necessitating additional clearances in the door for rail packaging.
Innovation Solution
A pivoting cursor for frameless vehicle windows, comprising a main body portion, a pivoting plate, a clamping plate, a seal, and an adjusting screw with a locking nut, allowing for adjustments from the inboard side, enhancing stiffness and reducing the need for additional clearances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustments are performed on the regulator rail by means of slotted brackets or jack screws, then the glass sealing in the Y direction can be adjusted, but the stiffness of the system is limited and additional clearances are needed in the door for rail packaging
Solution Approach 1:
The patent introduces a cursor as an intermediary component between the regulator rail and the glass panel. The cursor includes a body that slides on the rail and a separate adjustment mechanism with a threaded rod and adjustment screw that pivots the cursor relative to the rail. This intermediary structure allows precise glass positioning while maintaining rail stiffness, as the adjustment function is decoupled from the rail structure itself.
2Adaptability or versatility
If adjustments are performed on the regulator rail by means of slotted brackets or jack screws, then the glass sealing in the Y direction can be adjusted, but costly tools and components are required
Solution Approach 1:
The adjustment mechanism is designed to be self-contained within the cursor assembly. The threaded rod with external threads and the adjustment screw with a knurled head allow for tool-free or simple tool adjustment directly at the installation location. The cursor body with its sliding mechanism and pivoting capability provides all necessary adjustment functions without requiring external costly tools or specialized components.
3Adaptability or versatility
If adjustments are performed on the regulator rail by means of slotted brackets or jack screws, then the glass sealing in the Y direction can be adjusted, but the glass system deflection is adversely affected
Solution Approach 1:
The system is segmented into distinct functional components: the regulator rail for support, the cursor body for sliding movement, and the adjustment mechanism for precise positioning. The cursor acts as a separate segment that can be adjusted independently without affecting the overall rail structure or glass panel integrity. This segmentation allows for precise control of glass position and minimizes unwanted deflection in the glass system.
