Operable Ramp for Space-Saving Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ramps that provide access to buildings with steps are either too large and aesthetically unappealing or require significant space for deployment, failing to efficiently address the need for space-saving solutions that maintain accessibility for physically challenged individuals.
Innovation Solution
A moveable operable ramp that transitions between a raised step position and a lowered ramp position, utilizing a system of rotatably coupled panels and a drive assembly with a motor and linkage to minimize space usage while ensuring accessibility, with a frame attachment for stability and a retractable design for compact deployment.

1Reliability
If a fixed ramp is installed to provide accessible entry, then accessibility is improved, but space consumption increases and aesthetic quality deteriorates
Solution Approach 1:
The ramp is designed as a moveable structure that can transition between a deployed state (providing accessibility) and a retracted state (minimizing space consumption). The ramp includes panels that can be positioned at different angles and locations, allowing it to adapt between providing a ramp surface for wheelchairs and being stored in a compact configuration when not in use.
2Area of stationary object
If a fold out ramp is used to reduce space consumption, then space usage is improved, but deployment area requirements increase
Solution Approach 1:
The ramp is divided into multiple separable panels that can be independently positioned and configured. This segmentation allows the ramp to be stored in a compact folded state within a limited space while still providing sufficient deployment area when extended for use. The panels can be arranged in different configurations to optimize both storage compactness and deployment functionality.
3Area of stationary object
If a moveable ramp system is implemented to minimize space, then space efficiency is improved, but system complexity increases
Solution Approach 1:
Multiple functional components are integrated into a unified moveable ramp system. The panels, support structures, drive mechanisms, and control systems are combined into a single coordinated assembly that provides both ramp and step functions. This merging reduces the need for separate structures and simplifies the overall system while achieving space efficiency through the integrated moveable design.

AI summary
An operable ramp is moveable between a raised position and a lowered position. In the raised position, the operable ramp forms a step. The operable ramp has a first panel rotatably coupled at a first end about a first axis. The first axis moves in a first direction when the operable ramp moves toward the lowered position and in a second direction when the operable ramp moves toward the raised position. The operable ramp further includes a second panel rotatably coupled at a first end to a second end of the first panel. The first panel and the second panel cooperate to provide an inclined surface when the operable ramp is in the lowered position. A linkage is operably coupled to the first panel to selectively rotate the first panel about the first axis.
