Sliding Window Cable Drive with Integrated Conductive Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding window assemblies for vehicles face challenges in packaging space due to separate systems for automatically opening and closing the sliding panel and defrosting, which require independent motor and cable systems along with separate electrical wiring for the heating grids.
Innovation Solution
A sliding window assembly and cable drive system where a conductive element is integrated with the cable, allowing it to move concurrently with the sliding panel, thus eliminating the need for separate devices to open, close, and defrost the panel, and ensuring the heating grid remains electrically connected in both open and closed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If separate motor and cable systems are used for automatically opening and closing the sliding panel, then the panel can be moved automatically, but the packaging space within the vehicle increases
Solution Approach 1:
The patent combines the motor and cable systems into an integrated assembly where the motor is mounted within the cable housing. This merging eliminates the need for separate motor mounting space and separate cable routing, thereby reducing the overall packaging space while maintaining automatic operation capability
Solution Approach 2:
The integrated motor-cable assembly serves multiple functions: the motor provides automatic actuation, the cable transmits mechanical force, and the housing protects both components. This multi-functional design reduces the number of separate components needed, thereby reducing packaging space
2Adaptability or versatility
If separate electrical wiring is used to energize the heating grids, then the heating function can be provided, but the packaging space and system complexity increase
Solution Approach 1:
The patent integrates the electrical wiring for the heating grid into the same cable assembly that houses the motor and cable system. The wiring is routed through the cable housing, eliminating the need for separate wiring harnesses and reducing packaging space
3Reliability
If contact switches or connectors are used between the sliding panel and fixed panels, then electrical connection can be established, but durability and noise issues arise
Solution Approach 1:
The patent replaces mechanical contact switches and connectors with a sliding contactless electrical connection system. Electrical contacts are integrated into the sliding panel assembly, allowing continuous electrical connection without mechanical engagement/disengagement, thereby eliminating noise and improving durability

AI summary
A cable drive system and a sliding window assembly for a vehicle are disclosed. The sliding window assembly includes a track adapted to be coupled to the vehicle. The sliding window assembly further includes a sliding panel coupled to the track and movable relative to the track between an open position and a closed position. A heating grid is coupled to the sliding panel for defrosting the sliding panel. The sliding window assembly also includes a cable coupled to the sliding panel for moving the sliding panel between the open and closed positions. In addition, the sliding window assembly includes a conductive element electrically connected to the heating grid and coupled with the cable such that the conductive element moves concurrently with the cable as the cable moves the sliding panel between the open and closed positions.
