Solution Overview
Problem
Existing vehicle window shade systems lack adaptability to varying window distances and efficient motorized control for seamless operation across multiple window types within a vehicle.
Innovation Solution
A vehicle window shade system featuring telescoping support bars and motorized cable mechanisms that allow the shade to extend and retract uniformly across different window frames, powered by motors and controlled by a switch for automatic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed-length support bars are used, then the structure is simple, but the system cannot adapt to varying window distances
Solution Approach 1:
The support bars are designed with telescoping capability, allowing them to dynamically adjust their length to match varying window distances. This dynamic adjustment mechanism enables the same support bar structure to accommodate different window sizes and positions throughout the vehicle, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The support bar length parameter can be changed through the telescoping mechanism, allowing the physical dimension of the support bar to vary based on the specific window installation requirements. This parameter change capability enables a single support bar design to serve multiple window configurations without requiring custom-length bars for each window.
2Ease of operation
If manual operation is used, then the device complexity is low, but the ease of operation and user convenience are reduced
Solution Approach 1:
The manual mechanical operation system is replaced with an electric motorized system. The motor automatically operates the telescoping support bars and shade mechanisms, eliminating the need for manual adjustment. This substitution significantly improves ease of operation while the integrated control system manages the added mechanical complexity.
Solution Approach 2:
The motorized system enables the shade to operate autonomously without requiring user intervention for adjustment. The system can automatically extend and retract the support bars and position the shade, providing self-service functionality that enhances user convenience while reducing the operational complexity for the end user.
3Adaptability or versatility
If separate systems are used for different window types, then each window can be optimized, but the overall system complexity increases
Solution Approach 1:
A single universal support bar design with telescoping capability is created that can serve multiple window types including front side windows, rear side windows, and potentially windshield applications. This universal design approach allows the same basic mechanism to be adapted to different window configurations, reducing overall system complexity compared to having separate dedicated systems for each window type.
Solution Approach 2:
The support bar is segmented into telescoping sections that can independently extend or retract. This segmentation allows the single support bar structure to adapt to different span requirements for various window types, enabling one standardized component design to replace multiple custom-designed components.

Function Achieved in This Case
Enables flexible and uniform shading across various vehicle windows, accommodating different distances and providing efficient, motorized control for easy operation, enhancing user convenience and adaptability.
Implementation Method 1
At least a part of the top support bar and/or the bottom support bar is made from elastic materials or telescoping parts such that the support bars may be extended to reach the varying distances between the first side rail and the second side rail.

AI summary
A vehicle window shade system for providing shade to the interior of a vehicle. A first guide rail and a second guide rail are attached to a vehicle window frame. The shade is supported by a top support bar and a bottom support bar. At least a part of the top support bar and/or the bottom support bar is made from elastic materials or telescoping parts such that the support bars may be extended to reach the varying distances between the first side rail and the second side rail. The shade expands by pressing a switch that triggers a motor to uncoil a cable and move the top support bar up the first and second guide rails.
