Vehicle Sliding Window Power Supply via Guide Rail Cord
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power supply apparatus for sliding windows in vehicles is complex, making it difficult to integrate between the rear panel and trim board, and often fails to provide consistent power to electrical equipment like heating wires due to its curved design.
Innovation Solution
A power supply system featuring a guide rail integrated with the vehicle body, a sliding bracket with both sliding and fixed portions, and an extendable electrical power supply cord along the guide rail, ensuring power delivery to the sliding panel regardless of its position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a band-shaped flexible cable is used to supply electric power to the heating wire, then power can be supplied regardless of the opening and closing state of the sliding window, but the cable must be curved in a circular-arc shape requiring fixing and holding mechanisms, making the power supply apparatus complex
Solution Approach 1:
The power supply system is segmented into three functional components: a guide rail fixed to the vehicle body, a sliding bracket attached to the sliding panel, and an extendable power supply cord. This segmentation allows each component to perform its specific function independently, eliminating the need for complex circular-arc fixing mechanisms while ensuring continuous power supply during window movement.
Solution Approach 2:
The power supply cord acts as an intermediary element between the guide rail and the sliding bracket. It can extend and retract along the guide rail to maintain electrical connection during window movement, serving as a flexible mediator that simplifies the overall power supply structure compared to rigid curved cable arrangements.
2Reliability
If the power supply apparatus has a complex structure, then it can accommodate the flexible cable, but a technical difficulty occurs in vehicle layout such that the power supply apparatus may not be easily provided between the rear panel and the trim board
Solution Approach 1:
By dividing the power supply system into separate components (guide rail, sliding bracket, and power cord), the apparatus becomes modular and can be easily integrated into the vehicle layout between the rear panel and trim board without requiring a complex monolithic structure.
Solution Approach 2:
The guide rail is disposed along the sliding direction of the window panel, utilizing the linear dimensional space available in the vehicle body structure. This linear arrangement along the sliding path allows easy integration into the vehicle layout without interfering with other components.
3Device complexity
If a fixed curved cable arrangement is used, then the structure is simpler, but the cable cannot accommodate the sliding movement of the window panel, failing to supply power when the window is open
Solution Approach 1:
The power supply cord is designed to be extendable and retractable along the guide rail, allowing it to dynamically adapt its length and position according to the sliding window's movement. This dynamic capability ensures continuous power supply whether the window is open or closed, while maintaining a relatively simple overall structure.
Solution Approach 2:
The extendable power supply cord serves as a flexible intermediary that can adjust its configuration to accommodate window movement, bridging the gap between the fixed guide rail and the moving sliding bracket without requiring a complex rigid structure.

AI summary
A sliding window for a vehicle includes: a sliding panel with an electrical equipment, which is attached to a vehicle body in a slidable manner; a guide rail which is integrated with the vehicle body and extending in the slide direction of the sliding panel; and a sliding bracket which integrally includes a sliding portion coupled to the guide rail in a slidable manner and a fixed portion fixed to the sliding panel. Then, an electrical power supply cord is disposed along the guide rail to be extended and contracted in one direction, and the electrical power supply cord supplies electric power to the electrical equipment of the sliding panel.
