Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of components in vehicle doors for controlling light transmittance and movement of window glasses complicates manufacturing and assembly, leading to higher workloads and potential issues.
Innovation Solution
A window control device that integrates a window regulator and a light control device, with a restriction switch to manage movement and light transmittance, reducing the need for separate installations and simplifying the assembly process by sharing components and operation units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate operation panels and control devices are installed for window glass movement and light transmittance control, then the vehicle door can independently control each function, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent combines the operation panel for window glass movement control and the operation panel for light transmittance control into a single integrated operation panel. This merging reduces the number of separate components while maintaining the ability to independently control both window glass movement and light transmittance through different operation units within the same panel structure.
Solution Approach 2:
The integrated operation panel serves multiple functions: it controls both the window regulator for glass movement and the light control device for light transmittance adjustment. By designing a universal operation panel that handles both control tasks, the system reduces component count while preserving full control capability for both functions.
2Ease of operation
If multiple separate components are installed in the vehicle door for window control and light control, then each function can be controlled independently, but the assembly workload increases and assembly becomes more troublesome
Solution Approach 1:
The operation panel integrates both the window glass movement control unit and the light transmittance control unit into a single assembly. This merging reduces the number of separate assembly operations required during manufacturing and installation, thereby reducing assembly workload while maintaining the ability to independently control both functions through the integrated panel.
3Adaptability or versatility
If separate operation panels are used for window glass movement and light transmittance control, then each control function is independent, but the overall system size and component count increase
Solution Approach 1:
The patent merges the previously separate operation panels for window glass movement and light transmittance control into a single integrated operation panel. This reduces the component count from multiple separate panels to one unified panel, while the internal structure maintains independent control pathways for both functions, thus preserving adaptability while reducing quantity.

AI summary
A window control device includes a window regulator and a light control device. The window regulator controls movement of a light control glass that is installed in a vehicle door and a light transmittance of which can be adjusted. The light control device controls the light transmittance of the light control glass. The light control device is attached to one of the components constituting the window regulator.
