Vehicle Roof Switch Layout for Compact Glass and Sunshade Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing switch devices for vehicles require a large occupied area due to multiple operated portions for controlling the opening degree of a roof glass and the amount of light transmission through a sunshade, limiting layout flexibility in confined spaces.
Innovation Solution
A switch device with a first operated portion for displacing a roof glass in a first direction, a second operated portion for displacing it in a second opposite direction, and a third operated portion for adjusting light transmission, where the first and second operated portions are positioned in different directions relative to the third, allowing for a compact layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operated portions are provided for controlling opening degree and light transmission, then operational functionality is improved, but occupied area increases
Solution Approach 1:
The patent combines multiple operated portions (first for opening degree control, second for light transmission control, third for additional functions) into a single integrated switch device housing. This merging approach allows multiple control functions to be accessed from one compact location, improving operational functionality while containing the overall occupied area within a limited space on the vehicle interior.
Solution Approach 2:
The operated portions are arranged in a spatial configuration where they extend in different directions (first direction for opening/closing control, second direction for light transmission control) when viewed from a third operated portion. This multi-dimensional arrangement allows multiple functions to be accessed without requiring all controls to lie in the same plane, effectively reducing the occupied area footprint while maintaining full operational capability.
2Adaptability or versatility
If operated portions are arranged in different directions, then layout freedom is improved, but device complexity increases
Solution Approach 1:
The switch device is segmented into distinct operated portions with specific directional arrangements. The first operated portion is disposed in a first direction when viewed from the third operated portion, while the second operated portion is disposed in a second direction. This segmentation allows each portion to be optimized for its specific function while the overall device maintains a compact integrated structure, balancing layout freedom with manageable complexity.

AI summary
A switch device (1) includes a first part to be operated (11), a second part to be operated (12), and a third part to be operated (13). The first part to be operated (11) is configured to receive an operation of displacing, in a first direction, an opening/closing body (111) for changing the opening degree of an opening (O). The second part to be operated (12) is configured to receive an operation for displacing the opening/closing body (111) in a second direction opposite to the first direction. The third part to be operated (13) is configured to receive an operation for changing the amount of light passing through the opening/closing body (111) and the opening (O). The first part to be operated (11) is disposed in the first direction when viewed from the third part to be operated (13). The second part to be operated (12) is disposed in the second direction when viewed from the third part to be operated (13).
