Vehicle Window Sun Shade Panel Insertion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automobile sun shade devices are inadequate in blocking UV-A rays and providing comprehensive shade for drivers and passengers, as they often allow partial sun exposure and are not effectively held in place without using hooks, suction cups, or adhesives.
Innovation Solution
Custom-sized, semi-flexible sun shade panels are inserted between the vehicle window and its seal, utilizing the compressive force to hold them in place, allowing for adjustable blockage of sun rays and protection from both UV-A and UV-B rays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art sun shade devices are used with hooks, suction cups, or adhesives, then the shade device can be held in place, but the device complexity and ease of operation are reduced
Solution Approach 1:
The invention extracts the attachment function from separate components (hooks, suction cups, adhesives) and integrates it into the panel's edge itself. The panel is inserted between the window glass and the window seal, using the existing compressive force to hold it in place, eliminating the need for additional attachment mechanisms.
Solution Approach 2:
The panel utilizes the existing compressive force between the window glass and seal to secure itself without requiring external attachment devices. The panel's edge is inserted into the gap and held by the natural compression of the seal against the glass, making the system self-securing.
2Ease of operation
If prior art sun shade devices are used, then some shade is provided, but the blockage of sun rays is incomplete allowing partial sun exposure
Solution Approach 1:
The invention transitions from surface-level attachment to a three-dimensional insertion between the window glass and seal. By positioning the panel in this intermediate space, it creates a more effective barrier that completely blocks sun rays from reaching passengers, rather than just providing partial shade from the surface.
Solution Approach 2:
The panel is customized to fit specific window dimensions and shapes, providing complete coverage for each window area. The panel can be cut to match the exact contour of the window, ensuring no gaps for UV ray penetration while maintaining optimal shade coverage.
3Object-affected harmful factors
If custom sized panels are inserted between window and seal, then effective sun blockage is achieved, but the manufacturing precision and adaptability requirements increase
Solution Approach 1:
The panel dimensions and shape can be customized to match different window specifications. By adjusting the panel parameters (size, shape, thickness) to fit specific window gaps, the system achieves effective sun blockage while adapting to various vehicle models without requiring extreme manufacturing precision.
Solution Approach 2:
The solution allows for multiple panels to be used in combination, each panel being a simple standard size that can be cut or positioned to fit the window. This segmentation approach simplifies manufacturing while still achieving complete coverage through multiple smaller units rather than one large custom panel.
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 solution effectively blocks sun rays, providing greater comfort and protection for drivers and passengers by using the existing compressive force between the window and seal to secure the panels, which can be adjusted for maximum safety and visibility.
Implementation Method 1
the car window does not block UV-A rays. UV-A rays are also very dangerous because these are the rays that penetrate deep
Implementation Method 2
Custom sized sun shade panels are cut. A first sun shade panel is inserted between the window and window seal of the side window of a vehicle

AI summary
A method and device for blocking sun rays from shining through the side window of a vehicle. Custom sized sun shade panels are cut. A first sun shade panel is inserted between the window and window seal of the side window of a vehicle. Then at least one other sun shade panel is inserted adjacent to the first sun shade panel to form a stack of sun shade panels. The number of sun shade panels in the stack may be adjusted to achieve the desired blockage of sun rays from entering the vehicle.
