Magnetic Window Shade Positioning for Low-Angle Glare Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shades and sun visors in vehicles are ineffective in blocking sunlight or undesirable light sources from low angles, leading to impaired vision and increased risk of accidents, especially during sunrise or sunset driving.
Innovation Solution
An adjustable window shade with a magnetic attachment mechanism, featuring first and second magnets secured on opposite sides of the window, allowing for adjustable deployment and positioning to block light from any orientation, using a magnetic attachment point and a shade portion with a magnetic element for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional sun visor is used, then it can block light from high positions, but it cannot block light from low angles effectively
Solution Approach 1:
The window shade is made adjustable and movable along the window surface, transitioning from a fixed sun visor position to a dynamic positioning system. The magnetic attachment mechanism allows the shade to be repositioned freely to block light from any angle, not just high positions.
Solution Approach 2:
The invention moves the light-blocking function from the horizontal plane (sun visor extending forward) to the vertical plane (window shade moving up and down the window). This dimensional change enables blocking of low-angle light that enters from the side windows.
2Object-affected harmful factors
If fixed shading or tinting is applied to the window, then light blocking is provided, but the position cannot be adjusted by the driver
Solution Approach 1:
The magnetic attachment mechanism enables the window shade to be easily installed, removed, and repositioned by the driver without requiring tools or professional installation. The driver can independently adjust the shade position based on lighting conditions.
Solution Approach 2:
The system transforms from static fixed shading to a dynamic, repositionable shade that can be adjusted in real-time. The magnetic mechanism provides both secure attachment and easy repositioning capability.
3Ease of operation
If a magnetic attachment mechanism is used, then easy deployment and adjustment are achieved, but the attachment strength must be sufficient to hold the shade
Solution Approach 1:
The magnetic attachment function is extracted as a separate mechanism from the shade structure itself. Magnets are placed on both the shade and the window surface, creating a dedicated attachment system that provides both ease of handling and secure holding.
Solution Approach 2:
The magnetic force parameters are optimized to provide sufficient holding strength while allowing easy separation. The dual-magnet system (on shade and window) creates strong enough attraction to hold the shade securely but allows controlled detachment when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable window shade effectively blocks sunlight or other undesired light sources from any angle, enhancing driver and passenger safety by preventing glare and reducing eye irritation, regardless of the light source's orientation relative to the vehicle.
Implementation Method 1
The magnetic attachment point has first and second magnets adapted to be secured in position on the window by the relative attractive magnetic forces between the first and second magnets when the first and second magnets are collocated on opposite sides of the window
Data Source
AI summary
An adjustable window shade having a magnetic attachment point for mounting on a window and a shade portion with a magnet, the shade portion being detachably engageable with the magnetic attachment point via the magnet. Methods of installing and using the window shade are disclosed.
