Integrated Window Regulator Housing for Flexible Door Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window regulators are restricted in installation position due to the presence of a working hole, necessitating a configuration that avoids overlapping with the drum housing, limiting flexibility and increasing manufacturing complexity.
Innovation Solution
The window regulator integrates a drum housing and cover plate, molded as a single unit, allowing installation without being restricted by the working hole and reducing the need for additional fastening members, thereby simplifying the configuration and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the drum housing is positioned separately from the cover plate, then the window regulator can be installed on the door panel, but the installation position is restricted by the working hole location
Solution Approach 1:
The patent merges the drum housing and cover plate into a single integrally molded unit. This combination allows the window regulator to be installed without being restricted by the working hole position, as the integrated structure eliminates the need for separate positioning of these components. The merging resolves the technical contradiction by improving installation flexibility while maintaining structural integrity.
2Ease of manufacture
If the drum housing and cover plate are separate components, then assembly is possible, but additional fastening members are required increasing manufacturing complexity
Solution Approach 1:
By integrally molding the drum housing and cover plate as one piece, the patent eliminates the need for separate fastening members and assembly steps. This single-component design reduces the total number of parts, simplifies manufacturing processes, and lowers production costs while maintaining all necessary functional features.
3Adaptability or versatility
If the drum housing is positioned to avoid the working hole, then installation is possible, but the position of the window regulator with respect to the door panel is restricted
Solution Approach 1:
The integrated drum housing and cover plate structure enables the window regulator to adapt to various door panel configurations and working hole positions. The unified design provides greater installation area coverage and flexibility, allowing the regulator to be properly positioned regardless of where the working hole is located on the door panel.

AI summary
A window regulator installed on a door panel of a vehicle door. The window regulator includes a carrier plate that supports a window glass of the vehicle door, a guide rail that supports the carrier plate in an ascendable and descendible manner, a housing including a rail fitting portion to which an end portion of the guide rail is fitted, and a cover plate that closes a working hole of the door panel. The housing and the cover plate are integrally molded.
