Removable Car Sun Visor with Rotatable Clip and Sliding Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun visors for cars are ineffective in blocking sunlight from side windows, as they are not easily removable or adjustable to accommodate different window shapes and angles, and often obstruct rear passengers' views.
Innovation Solution
A removable sun visor with a rotatable clip, sliding members, and a tinted polycarbonate window that can be adjusted to fit various side window angles, allowing for optimal positioning and easy installation/removal, featuring a hinged connection to the clip, sliding members that match window corners, and a magnetic clasp for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sun visor is installed on the front windshield, then it blocks sunlight for front passengers, but it provides no use to rear passengers and cannot accommodate side window curves
Solution Approach 1:
The sun visor is divided into multiple segments: a front windshield visor portion and one or more side window visor portions that can be attached or detached. This segmentation allows the visor system to adapt to different window positions (front windshield and side windows) without requiring a completely different structure for each position.
Solution Approach 2:
The side window visor portions are designed to be movable and adjustable along the side window surface, allowing users to position them optimally to block sunlight from different angles. The visor can be attached, detached, and repositioned dynamically based on the user's needs and the sun's position.
2Adaptability or versatility
If a traditional sun visor shape is used, then it is simple in design, but it is difficult to block sunlight from the curved contours of side windows
Solution Approach 1:
The side window visor portions are designed with curved contours that match the shape of vehicle side windows. This curvature allows the visor to conform to the window's surface and effectively block sunlight from reaching passengers, while still being manufacturable using standard molding techniques.
3Adaptability or versatility
If a removable sun visor is designed to fit various window shapes, then it improves adaptability, but it increases device complexity
Solution Approach 1:
The visor includes adjustable components that can be moved to different positions and angles to accommodate various window shapes and sunlight angles. The adjustment mechanisms are designed to be simple and intuitive, allowing users to easily reposition the visor without complex controls.
Solution Approach 2:
The visor system is designed to perform multiple functions: blocking sunlight from both the front windshield and side windows, and serving both front and rear passengers. The same basic visor structure can be configured for different positions and angles, reducing the need for multiple specialized visors.
4Ease of operation
If a fixed plastic shade is used, then it is simple to manufacture, but it cannot be adjusted or removed and obstructs rear passenger views
Solution Approach 1:
The visor is designed to be removable and reattachable, allowing users to install it when needed and remove it when not needed or when it would obstruct rear passenger views. The attachment mechanism uses simple clips or adhesives that provide secure mounting without requiring complex fastening systems.
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 sun visor effectively blocks or filters sunlight from entering the vehicle, providing adjustable coverage and unobstructed rear passenger views, while being easy to install, remove, and store, with a tinted polycarbonate window allowing partial light transmission for visibility.
Implementation Method 1
a magnetic clasp for stability
Implementation Method 2
A removable sun visor with a rotatable clip, sliding members, and a tinted polycarbonate window that can be adjusted to fit various side window angles, allowing for optimal positioning and easy installation/removal, featuring a hinged connection to the clip, sliding members that match window corners, and a magnetic clasp for stability.

AI summary
Improvements in a removable sun visor for car windows is disclosed. The visor uses a rotatable and removable window clip so the user can install and move the visor when needed to block or filter sunlight from entering the vehicle. The clip can also be rotated and locked on an angled side of a window to block or filter light that can enter the vehicle from a far forward edge. The rotating feature has locks or detents to hold the visor at the adjusted angle. The rotatable clip can further be positioned on either side of the visor for positioning on either side of a vehicle. There is also an adjustable tinted window that allows the user to look through the tinted portion. Side portions can be moved in or out of the main housing to block light. Magnets can be used to secure moving members.
