Retractable Dashboard Sunshade for Vehicle Display Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen sunshades for vehicles do not effectively reduce sun glare on dashboard displays.
Innovation Solution
A retractable sunshade system with a housing and pivotally attached blades that extend to block sunlight, coupled with a retractor mechanism to retract the sunshade when not in use, mounted removably to the dashboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sunshade is permanently deployed to block sunlight, then sun glare on display screen is reduced, but device complexity and space occupation increase
Solution Approach 1:
The sunshade is designed to be retractable rather than fixed, allowing it to dynamically adjust between deployed and retracted positions. The retractor mechanism enables the sunshade to be extended when sun glare is present and retracted when not needed, providing adaptive protection while maintaining a compact form when the function is not required.
Solution Approach 2:
The sunshade blades are arranged in a nested configuration where multiple blades can be stacked or folded into each other when retracted. This nesting arrangement allows the sunshade to occupy minimal space within the housing when not in use, while still providing adequate coverage when deployed.
2Ease of operation
If a retractable sunshade mechanism is added, then ease of operation improves, but device complexity increases
Solution Approach 1:
The retractor mechanism is designed to automatically retract the sunshade blades using spring-loaded or elastic recovery elements. When the user releases the sunshade, it self-retracts without requiring manual operation, reducing the operational steps needed while keeping the mechanism relatively simple through the use of passive mechanical recovery forces.
3Object-affected harmful factors
If sunshade blades are extended to cover display screen, then visibility protection improves, but loss of time for deployment occurs
Solution Approach 1:
The sunshade is pre-positioned within the housing in a ready-to-deploy state, with the retractor mechanism pre-loaded with stored energy (spring or elastic). When deployment is needed, the user simply triggers the release mechanism, and the pre-stored energy rapidly propels the blades into the protective position, minimizing deployment time.

AI summary
A vehicle dashboard sunshade system for reducing sun glare upon a display screen within a vehicle includes a vehicle having dashboard is positioned within the vehicle. A display screen is mounted on the dashboard and a housing is removably positioned above the display screen. The housing includes a top wall, a bottom wall, a front wall, a back wall, a first side wall, and a second side wall. A sunshade is coupled to the front wall and retractably extends from a closed position to an open position, wherein the open position guards the display screen from sunlight. A retractor is mechanically coupled to the sunshade and retracts the sunshade from an open position to a closed position when actuated. A mount is attached to the back wall of the housing and removably mounts the housing to the dashboard.
