Universal Vehicle Window Lifting Device via Door Panel Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in creating a lifting device for vehicle windows that can be universally applicable across different side doors within a door series, as existing devices require distinct support plates due to varying window glass sizes and lifting directions, leading to inefficiencies in production and increased costs.
Innovation Solution
The lifting device incorporates a support plate with a through hole, where a stopper is provided on the inner panel of the door, allowing for commonization of the support plate across different door series by eliminating the need for multiple support plates based on specific window glass configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stopper is provided at a lower section of the support plate to prevent the window glass from moving downward beyond a predetermined position, then the window glass moving range is controlled, but a different support plate needs to be prepared for each kind of side door, reducing production efficiency
Solution Approach 1:
The stopper function is segmented from the support plate. The support plate becomes a universal component without the stopper, while the stopper is provided separately on the inner panel of the door. This segmentation allows the support plate to be commonized across different door types while the stopper position can be adjusted to control window glass movement for each specific door configuration.
Solution Approach 2:
The inner panel of the door acts as an intermediary carrier for the stopper. Instead of integrating the stopper directly into the support plate, the stopper is mounted on the inner panel which then interacts with the support plate assembly. This intermediary approach enables flexible stopper positioning while maintaining a standardized support plate design.
2Adaptability or versatility
If the support plate is customized for each kind of side door to accommodate different window glass sizes and lifting directions, then the lifting device fits each door configuration, but multiple support plate variants increase manufacturing complexity and cost
Solution Approach 1:
The support plate is designed as a universal component that can be applied to all side doors within a door series regardless of window glass size or lifting direction variations. The support plate maintains consistent dimensions and mounting features, while door-specific adaptations are achieved through external components like the stopper positioned on the inner panel, not integrated into the support plate itself.
