Pivoting Cursor for Vehicle Frameless Window Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frameless window systems in vehicles face limitations in stiffness, cost, and glass system deflection due to the existing adjustment methods using slotted brackets or Jack screws, which also require additional clearances in the door for rail packaging.
Innovation Solution
A pivoting cursor system for vehicle windows, comprising a main body, a pivoting plate, a glass clamping plate, a seal, a first adjusting screw for pivoting the plate, and a second adjusting screw to adjust the location of the main body with respect to the pivoting plate, allowing for precise adjustment and improved stiffness without the need for additional clearances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slotted brackets or Jack screws are used for glass sealing adjustment, then adjustment capability is provided, but system stiffness is limited and additional door clearances are required
Solution Approach 1:
The cursor assembly incorporates a pivoting plate that can rotate about a pivot axis, transforming the static bracket connection into a dynamic adjustable connection. This allows the glass support position to be adjusted by pivoting the plate while maintaining structural integrity during operation
Solution Approach 2:
The adjustment mechanism is divided into separate functional components: a cursor body for sliding along the rail, a pivoting plate for angular adjustment, and adjusting screws for precise positioning. This segmentation allows each component to perform its specific function optimally while contributing to overall system stiffness
2Adaptability or versatility
If slotted brackets or Jack screws are used for glass sealing adjustment, then adjustment capability is provided, but system cost increases due to additional tools and components
Solution Approach 1:
The cursor assembly serves multiple functions: it supports the glass, provides adjustment capability through the pivoting plate, allows positioning along the rail via the cursor body, and enables precise adjustment through adjusting screws. This multi-functionality eliminates the need for separate adjustment mechanisms and reduces overall system complexity
Solution Approach 2:
The invention merges the glass support function, adjustment function, and positioning function into a single integrated cursor assembly. This consolidation reduces the number of separate components and tools needed, thereby reducing system cost and complexity
3Adaptability or versatility
If adjustment is performed on the rail, then glass sealing adjustment is achieved, but additional clearances are needed in the door for rail packaging
Solution Approach 1:
The adjustment mechanism utilizes angular movement of the pivoting plate about a pivot axis rather than requiring linear movement along the rail. This dimensional change from linear to angular adjustment eliminates the need for additional rail length and reduces door clearance requirements
