Vehicle Window Light-Shielding Body Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle window systems fail to accommodate both the need for a comfortable, unobstructed view and the desire to enjoy a wider scenic view, as existing sunshades cannot increase the opening area of the window.
Innovation Solution
A window device featuring a light-transmitting plate and a light-shielding body with a moving mechanism that allows the light-shielding body to move up and down, adjusting the view through the light-transmitting plate to accommodate occupant preferences for comfort and scenic enjoyment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sunshade is installed on the window, then the comfort of the occupant is improved by shading the window according to personal preference, but the opening area of the window cannot be increased to enjoy a wide range of scenery
Solution Approach 1:
The patent applies the dynamics principle by making the light-shielding body movable rather than fixed. The light-shielding body can move up and down along the light-transmitting plate, allowing the window opening area to be dynamically adjusted. When the light-shielding body moves downward, the opening area increases for enjoying scenery; when it moves upward, the opening area decreases for comfort and shading.
2Area of stationary object
If the window opening area is increased to enjoy a wide range of scenery, then the scenic view is improved, but the comfort of the occupant is reduced due to direct light and glare
Solution Approach 1:
The dynamics principle allows the light-shielding body to move to different positions. When the window opening area needs to be increased for scenery, the light-shielding body can be positioned to shield specific areas that cause glare or excessive light exposure, while maintaining the larger opening for the scenic view.
Solution Approach 2:
The light-shielding body provides local quality by selectively shielding specific portions of the window rather than the entire window. This allows different areas of the window to have different functions - some areas for scenery viewing, others for light shielding - thereby resolving the contradiction between opening area and light exposure control.
3Device complexity
If a fixed sunshade is installed, then the device complexity is reduced, but the adaptability to different occupant preferences is limited
Solution Approach 1:
The movable light-shielding body adds dynamic capability to the window device, enabling it to adapt to different occupant preferences. The light-shielding body can be positioned at different heights and locations to provide various levels of shading and opening area, thereby increasing adaptability while maintaining relatively simple device structure.

AI summary
A window device for a vehicle, the window device including: a light-transmitting plate having light-transmitting property and fixed to a vehicle body to physically partition an exterior and an interior of the vehicle; a light-shielding body having light-shielding property and provided along the light-transmitting plate within a view of a vehicle occupant; and a moving mechanism configured to move the light-shielding body up and down so as to widen or narrow a view obtained through the light-transmitting plate above the light-shielding body.
