Vehicle Window Regulator Assembly with Cable Tube and Motor Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing non-module type dual regulator assembly for vehicle windows is difficult to assemble and generates noise during operation due to the requirement of holding guide rails during installation and the contact between the cable and door panels.
Innovation Solution
A non-module type dual regulator assembly with a pair of guide rails separated by a connection member, where the guide rails are fastened using locking hooks and insertion components, and a driving motor is positioned in the lower connection member to reduce noise and facilitate assembly by eliminating the need to hold guide rails during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pair of guide rails are separated from each other, then the regulator assembly can be mounted in the door space, but the assembly process becomes difficult and requires manual handling of guide rails
Solution Approach 1:
The patent connects the separated guide rails through connection members (upper connection member 13 and lower connection member 14) to form an integrated assembly. The connection members include locking hooks that engage with the guide rails, merging them into a single unit that can be installed without manual handling of individual rails, thus resolving the contradiction between space utilization and assembly ease.
2Ease of operation
If the cable circulates through the rollers and contacts the door panels, then the cable can be operated, but noise is generated during operation
Solution Approach 1:
The patent introduces a tube (119) as an intermediary component that covers the cable (118). This tube acts as a mediator between the cable and the door panels, preventing direct contact and the resulting noise while still allowing the cable to circulate and operate through the rollers. The tube effectively eliminates the harmful noise factor without compromising cable operation.
3Object-generated harmful factors
If the driving motor is positioned in the lower connection member, then the noise and weight are reduced, but the motor positioning becomes more constrained
Solution Approach 1:
The patent segments the regulator assembly into distinct functional components: the lower connection member (14) serves as a separate module that houses the driving motor (16). This segmentation allows the motor to be positioned in the lower connection member, reducing overall noise and weight by distributing components strategically. The modular segmentation resolves the positioning constraint by providing a dedicated space for the motor within the connection member structure.

AI summary
A non-module type dual regulator assembly includes a pair of guide rails that are separated from each other and disposed in a door of a vehicle along a direction that a window glass is raised or lowered. A pair of glass holders are coupled to one side of the window glass and movably disposed on the respective guide rails. An upper connection member has a plurality of ends fastened to upper portions of the guide rails. A lower connection member has a plurality of ends fastened to lower portions of the guide rails. A cable is coupled to the glass holders and circulatably disposed along the guide rails to raise or lower the glass holders in the same direction at the same time. A driving motor is disposed on the lower connection member and circulates the cable.
