Vehicle Panel With Wheelchair Wheel Channels And Electronic Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passenger vehicles are not designed to accommodate wheelchairs, requiring aftermarket modifications for wheelchair accommodations, which can be cumbersome and inadequate for secure seating during vehicle operation.
Innovation Solution
A vehicle panel system with channels to engage wheelchair wheels and an electronic latch mechanism, supported by a wiring harness connected to a computer, allowing for secure wheelchair positioning and integration with existing vehicle safety systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lift or aftermarket modification is installed to load a wheelchair onto a vehicle, then wheelchair accessibility is improved, but device complexity and cost increase
Solution Approach 1:
The panel assembly serves multiple functions: it acts as a structural floor panel, provides channels to receive and secure wheelchair wheels, incorporates latches for wheel retention, and integrates with vehicle safety systems. This multi-functionality eliminates the need for separate lift mechanisms while achieving wheelchair accessibility.
Solution Approach 2:
The panel is divided into functional segments including channels for wheel reception, latches for securing, and mounting interfaces for vehicle integration. This segmentation allows each component to perform its specific function while maintaining overall system simplicity.
2Adaptability or versatility
If significant aftermarket modification is required to accommodate a wheelchair in a vehicle seat, then wheelchair accommodation is achieved, but ease of manufacture and installation deteriorate
Solution Approach 1:
The panel assembly replaces the need for significant aftermarket modifications by providing an integrated solution that combines structural support, wheel engagement, and safety integration into a single manufacturable unit.
Solution Approach 2:
The panel nests within the existing vehicle floor structure, with channels and latches integrated into the panel itself. This nesting approach allows the wheelchair accommodation system to be incorporated into the existing vehicle architecture without requiring extensive external modifications.
3Area of stationary object
If a wheelchair is stowed in the cargo area, then space is utilized, but the occupant cannot sit in the wheelchair in the vehicle
Solution Approach 1:
The panel assembly enables the passenger area to serve dual purposes: it can accommodate a wheelchair with an occupant seated in it, or it can be configured for other uses. The channels and latches provide secure retention while allowing the occupant to remain in the wheelchair during vehicle operation.
4Device complexity
If production vehicles are designed without wheelchair accommodation features, then vehicle design simplicity is maintained, but adaptability to wheelchair users deteriorates
Solution Approach 1:
The panel assembly provides wheelchair accommodation capabilities while maintaining compatibility with standard vehicle floor structures and safety systems. The design integrates seamlessly with existing vehicle architecture, adding adaptability without significantly increasing overall vehicle complexity.
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
Enables secure and safe transportation of wheelchair users by allowing the wheelchair to be stowed within the vehicle, with the electronic latch ensuring wheel stability during sudden decelerations and integration with airbags and seatbelts for enhanced safety.
Implementation Method 1
The latch may include a solenoid including a body mounted to the panel and a post extendable from the body

AI summary
An assembly for a vehicle includes a panel. The panel includes a first channel and a second channel spaced from and parallel to each other. The first and second channels are designed to engage wheels of a wheelchair. The assembly includes a latch supported by the panel. The latch is moveable between an unlatched position and a latched position. The latch is retracted from the first channel in the unlatched position and elongated across the first channel in the latched position. The panel includes releasable connections designed to releasably engage a vehicle floor.
