Motorized Parking Placard Holder for Vehicle Sun Visor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions do not provide a convenient and visible method to display and hide a parking placard on a vehicle's sun visor, especially when the vehicle is in operation or parked.
Innovation Solution
A system comprising a visor clip, a placard clip, a first servo motor, a second servo motor, a controller, and a remote control key fob that allows the parking placard to be moved between a non-visible and visible position on the sun visor, using activation signals to control the motorized movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the parking placard is always displayed on the sun visor, then visibility is improved, but it creates safety hazards when the vehicle is in operation
Solution Approach 1:
The parking placard display is made dynamic through motorized rotation mechanisms that allow the placard to be positioned in different orientations. The system can rotate the placard between a visible position (when parked) and a hidden position (when driving), enabling the display state to adapt to different operational conditions and eliminate safety hazards while maintaining visibility when needed
2Loss of information
If the parking placard is manually moved between visible and hidden positions, then visibility control is achieved, but ease of operation deteriorates
Solution Approach 1:
The system employs sensors to automatically detect whether the vehicle is parked or in operation, and autonomously controls the motorized rotation mechanism to position the parking placard accordingly. This self-service capability eliminates the need for manual intervention, allowing the placard to automatically transition between visible and hidden states based on vehicle status, thereby significantly improving ease of operation
Solution Approach 2:
The system incorporates sensors that provide feedback about the vehicle's operational state (parked or driving) to the control mechanism. This feedback loop enables the system to automatically adjust the placard's visibility status in response to changing conditions, eliminating manual operation while maintaining appropriate visibility control
3Ease of operation
If a motorized system is added to move the parking placard, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The motorized system is segmented into independent functional modules: rotation motors for positioning, sensors for detecting vehicle status, and control circuits for coordinating operation. This modular segmentation allows each component to perform a specific function, simplifying the overall system design and maintenance while providing automated operation capability

AI summary
The permit holder for a vehicle sunvisor comprises a visor clip, a placard clip, a first servo motor, a second servo motor, a controller, and a remote control key fob. The permit holder for a vehicle sunvisor may removably couple to a sun visor in a vehicle via the visor clip and may removably couple a parking placard to the sun visor such that the parking placard may be stored in a non-visible position during the operation of the vehicle and displayed in a visible position when the vehicle is parked. Upon receiving an activation signal from the remote control key fob, the controller may cause rotation of the first servo motor and the second servo motor thus moving the parking placard between the non-visible position and the visible position.
