Vehicle Sun Visor Permit Holder with Adjustable Pivots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a mechanism to securely attach and position a parking placard on a vehicle sun visor such that it is hidden during vehicle operation but becomes visible when parked, with adjustable orientation for maximum visibility.
Innovation Solution
A permit holder system comprising a visor clip, master shaft, master clip, and pivots allows the parking placard to be attached and adjusted over azimuth and altitude angles, using a cantilever V spring mechanism and elastomeric materials for secure attachment and adjustable visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the parking placard is attached to the sun visor in a fixed position, then it is always visible, but it cannot be hidden during vehicle operation
Solution Approach 1:
The patent applies the dynamics principle by making the sun visor and parking placard assembly movable rather than fixed. The sun visor is hinged to the vehicle interior at the upper forward portion of the windshield, allowing it to rotate between a stored position (hiding the placard) and a deployed position (displaying the placard). This dynamic positioning enables visibility control without requiring complex active mechanisms.
Solution Approach 2:
The patent segments the parking placard attachment system into multiple independent components: the sun visor assembly, the parking placard holder, and the hinged connection mechanism. This segmentation allows each component to perform its specific function independently - the sun visor provides positioning and hiding capability, while the placard holder secures the placard in an optimized orientation.
2Ease of operation
If the parking placard is stored in a hidden manner during vehicle operation, then visibility is controlled, but it cannot be easily positioned for maximum visibility when parked
Solution Approach 1:
The patent employs dynamics by enabling the sun visor to rotate freely along its hinge axis, allowing users to adjust the placard's orientation to optimal viewing angles when parked. The hinged connection provides continuous rotational freedom rather than fixed angular positions, simplifying the adjustment process while maintaining positioning flexibility.
Solution Approach 2:
The patent merges the sun visor function with the parking placard display function into a single integrated assembly. The parking placard holder is attached to the sun visor, combining the sun protection function with the placard display function. This merging eliminates the need for separate adjustment mechanisms for both functions.
3Device complexity
If a simple attachment mechanism is used, then device complexity is reduced, but secure attachment and adjustable orientation cannot be achieved
Solution Approach 1:
The patent utilizes the curvature principle through the hinged connection design, which allows rotational movement along an arc path. The hinge mechanism provides a curved guide for the sun visor rotation, enabling smooth orientation adjustment while maintaining secure attachment through the hinge's mechanical constraint.
Solution Approach 2:
The patent introduces the hinged connection as an intermediary element between the vehicle interior and the sun visor assembly. This hinge mediator provides both secure attachment (through mechanical connection) and orientation freedom (through rotational capability), resolving the conflict between security and adjustability.

AI summary
The permit holder for a vehicle sun visor is configured for use with a vehicle. The permit holder for a vehicle sun visor attaches a parking placard to a sun visor within the vehicle. The parking placard may be: 1) stored in a non-visible manner during the operation of vehicle; and, 2) positioned in a visible manner when the vehicle is parked. The permit holder for a vehicle sun visor comprises a visor clip, a master shaft, a master clip, and a plurality of pivots. The master clip attaches to the parking placard. The master shaft attaches the master clip to the plurality of pivots. The plurality of pivots attaches the master shaft to the visor clip. The visor clip attaches to the sun visor. The plurality of pivots are arranged such that the orientation of the placard is adjustable.
