Vehicle Sunshade Single-Point Anchor Trim Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sunshade assemblies for vehicles obstruct the view and have an unfinished appearance due to protruding hooks or hook retainers near the window, especially in smaller windows, and are cumbersome to operate as they require attachment at multiple locations.
Innovation Solution
A sunshade assembly that secures in a single location using a recessed hook or hook retainer within a trim panel, with a handgrip-attached hook member that pivots to engage a corresponding retainer, allowing unobstructed view and intuitive operation by retracting into the trim panel when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hooks or hook retainers are mounted near the window to secure the sunshade, then the sunshade can be secured in a deployed position, but the view through the window is obstructed and the appearance is unfinished
Solution Approach 1:
The harmful element (protruding hook or hook retainer) is extracted from its traditional location near the window. Instead, the hook retainer is recessed into the trim panel, removing the visual obstruction while maintaining the sunshade securing function. The hook member remains visible and operable from the interior but does not block the window view when retracted.
Solution Approach 2:
The hook retainer is nested within a recess in the trim panel, allowing it to be hidden from view when not in use. The recess accommodates the hook retainer body, and when the sunshade is retracted, the hook member can be positioned within or near the recess without protruding into the window viewing area.
2Reliability
If hooks are provided to secure the sunshade, then the sunshade can be retained in deployed position, but multiple attachment locations are required making operation cumbersome
Solution Approach 1:
The hook member and handgrip are combined into a single integrated component. The handgrip serves dual purposes: as a handle for easy manipulation and as part of the securing mechanism. This eliminates the need for separate attachment operations at multiple locations, as the single handgrip-hook assembly engages with the recessed hook retainer to secure the sunshade.
Solution Approach 2:
The handgrip portion of the hook member serves multiple functions: it provides a grip for user operation, acts as part of the mechanical linkage for engagement, and helps position the hook portion during the securing operation. This multi-functionality simplifies the overall operation compared to traditional multi-point attachment systems.
3Volume of moving object
If the sunshade is retracted completely, then it is stored compactly, but protruding securing members would obstruct the view and interfere with trim panel surfaces
Solution Approach 1:
The hook member is designed to be dynamic rather than fixed. It can pivot or rotate about its attachment point to the sunshade, allowing it to assume different positions. When the sunshade is retracted, the hook member can be positioned to clear the trim panel opening and avoid interfering with the trim panel surfaces, while still maintaining engagement with the recessed hook retainer.
Solution Approach 2:
The hook member is positioned in three-dimensional space relative to the trim panel opening. By allowing the hook member to extend at an angle or pivot into a different spatial plane, it can clear the trim panel opening area when retracted, preventing interference with surrounding surfaces while maintaining its securing function through the recessed hook retainer.

AI summary
A sunshade assembly wherein the sunshade is secured in a deployed position at a single location, and wherein when the sunshade is retracted, the field of view through the window is unobstructed by securing members or the like. More particularly, the sunshade assembly utilizes a recessed hook or hook retainer within a trim panel adjacent the window as an anchor point, while a handgrip secured to the window shade is configured to pivot into a position to permit a hook or hook retainer associated therewith to be inserted into the recessed anchor point.
