Adjustable Glass Gripping Device for Vehicle Window Regulator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power window regulators lack a fine-tuning mechanism, making it laborious and time-consuming to ensure the window glass aligns perfectly with the door frame, as they cannot adjust once raised due to inaccuracies in the rail or window shape.
Innovation Solution
An adjustable glass gripping device with a rotatable bolt mechanism, comprising a glass gripper, limiter, and adjusting bolt, allows for precise alignment by sliding along a rail with a linking element, enabling fine-tuning of the window glass position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional glass grippers are used without a fine-tuning mechanism, then the structure is simple, but the window cannot be precisely aligned with the door frame requiring laborious manual adjustment
Solution Approach 1:
The glass gripper incorporates an adjustable bolt mechanism that transforms a static gripping structure into a dynamic one, allowing the gripper position to be fine-tuned along the rail. This enables precise window alignment while maintaining structural simplicity through a single adjustable parameter.
2Manufacturing precision
If the window is released by the glass gripper to correct position, then alignment can be achieved, but the process becomes time-consuming and laborious
Solution Approach 1:
The adjustable bolt mechanism allows the glass gripper to be pre-positioned at the correct location before the window is installed. This preliminary adjustment eliminates the need for time-consuming post-installation corrections, as the gripper is already configured to hold the window in the precise alignment position.
3Manufacturing precision
If the rail is inaccurately oblique or window shape does not correspond to door, then alignment errors occur, but conventional grippers cannot compensate for these errors
Solution Approach 1:
The adjustable bolt mechanism provides a variable parameter (bolt position along the rail) that can be changed to compensate for rail obliquity or window shape mismatches. By adjusting the bolt position, the gripper can adapt to different alignment requirements and compensate for manufacturing tolerances in the rail or window components.

AI summary
A window glass gripping device which is assembled on a rail with a linking element includes: a glass gripper, slidably connected on the rail; a limiter, secured on the linking element; and an adjusting bolt, screwed to the glass gripper, having a limited portion. The limiter is assembled to correspond to the limited portion for limiting a position of the adjusting bolt.
