Rear Slider Window Heating via Perimeter Flat Wires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional slider window assemblies for vehicles, particularly rear slider windows, fail to effectively defog or defrost both fixed and movable window panels when the movable panel is opened or partially opened, as the electrical connection to the heating elements is disrupted.
Innovation Solution
The implementation of laminated window panels with electrically conductive heating elements between glass substrates, connected via thin flat wires that wrap around the perimeter edges and maintain electrical continuity regardless of the movable panel's position, ensuring continuous heating or defogging capability for both fixed and movable panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical terminals are used at the movable window panel, then electrical connection is maintained when closed, but electrical connection is disrupted when the movable panel is opened or partially opened
Solution Approach 1:
The patent uses a flexible flat wire to replace rigid electrical terminals and wiring. This flexible wire can bend and extend as the movable window panel moves between closed and open positions, maintaining continuous electrical connection to the heating element throughout the full range of motion, thereby resolving the contradiction between connection reliability and positional adaptability
2Ease of operation
If the movable window panel is opened for ventilation, then air flow is improved, but defogging or defrosting capability is lost
Solution Approach 1:
The patent ensures continuous electrical power supply to the heating element through the flexible flat wire connection, allowing the defogging or defrosting function to operate continuously regardless of whether the window is open, partially open, or closed. This maintains the useful heating action throughout all operational states, resolving the contradiction between window opening and defogging capability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for effective defogging or defrosting of both fixed and movable window panels, regardless of the movable panel's position, enhancing the heating functionality and maintaining electrical power supply throughout the range of motion.
Implementation Method 1
an electrically conductive heating element disposed between inner and outer glass substrates of the respective window panel

AI summary
A rear slider window assembly for a vehicle includes a fixed window panel and a movable window panel that is movable between a closed position and an opened position. The movable window panel includes a laminated movable window panel having an electrical element disposed between an inner glass panel and an outer glass panel. The first electrical element is in electrical connection with a wire harness of the vehicle via a flexible connector electrically connected to a first electrical connector at an inner surface of the movable window panel and to a second electrical connector at the inner surface of the fixed window panel. The first electrical connector is electrically connected to the first electrical element via a thin flat connector that extends from the first electrical connector and wraps around a perimeter edge of the inner glass panel of the movable window panel.
