Vehicle Ramp Assembly Installation Using Movable Mounting Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fold-out ramps for vehicles face challenges such as limited length due to space constraints, increased weight with longer ramps, and installation complexities, which affect operability and accessibility for wheelchair-bound passengers.
Innovation Solution
A method for installing a ramp assembly into a vehicle using first and second ramp support members, where the ramp assembly is moved into a stowed position with a top surface facing upward and secured to the support members, allowing for horizontal movement and adjustment to be flush with the vehicle floor, enabling secure deployment and stowage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ramp length is increased to provide a more gradual slope for wheelchair accessibility, then the accessibility is improved, but the weight of the ramp increases and more torque is required to reciprocate it
Solution Approach 1:
The ramp assembly is designed with movable and adjustable components that allow it to change position and configuration dynamically. The ramp can be reciprocated between stowed and deployed positions, and the support assemblies allow for adjustment during installation to optimize performance while managing weight constraints.
Solution Approach 2:
The ramp system allows for parameter changes in length, position, and orientation. By adjusting the ramp length and support positions, the system can provide different slope gradients to accommodate accessibility requirements while managing the weight and torque requirements for operation.
2Ease of operation
If the ramp length is increased to improve accessibility, then the slope becomes more gradual, but the space required in the vehicle increases
Solution Approach 1:
The ramp assembly is designed to nest within the vehicle floor when in the stowed position. The support assemblies and ramp structure are configured to fit within the available space in the vehicle, allowing the ramp to be stored efficiently when not in use while still providing adequate length for accessibility when deployed.
Solution Approach 2:
The ramp system utilizes three-dimensional space efficiently by allowing the ramp to extend in multiple directions and configurations. The support assemblies enable the ramp to be positioned at different angles and locations, maximizing the use of available vertical and horizontal space within the vehicle.
3Stability of the object's composition
If the ramp assembly is secured firmly to prevent movement, then the stability is improved, but the installation complexity increases
Solution Approach 1:
The support assemblies are designed to be affixed to the ramp support members before final ramp installation. This preliminary action allows for pre-positioning and alignment, simplifying the subsequent steps of securing the ramp assembly and ensuring stability without requiring complex installation procedures.
Solution Approach 2:
The support assemblies act as intermediary components between the ramp assembly and the vehicle floor. These intermediaries simplify the connection process by providing standardized mounting interfaces and alignment features, reducing installation complexity while ensuring stable securing of the ramp.
