Pivotable Cargo Ramp Assembly for Space-Efficient Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading ramp systems for vehicles are either completely separate and cumbersome to maneuver or require complete removal and storage, lacking a convenient and space-efficient solution for transitioning between use and storage positions.
Innovation Solution
A loading ramp assembly that is pivotable and retractable within the cargo area, featuring segments that can extend beyond the cargo area for loading/unloading and retract completely inside for storage, with independent ramp bodies that can be secured vertically along the sidewalls, allowing for quick deployment and stowage without the need for removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ramp is completely separate and removable from the vehicle, then the ramp can be easily stored outside the cargo area, but the ramp becomes cumbersome to maneuver and requires complete removal for storage
Solution Approach 1:
The ramp is integrated with the vehicle's cargo area through a pivot connection, merging the ramp and vehicle into a single system. This allows the ramp to be stored within the cargo area by pivoting to a vertical position, eliminating the need for complete removal while reducing maneuvering complexity compared to separate ramps
2Area of stationary object
If the ramp is retractable and stored within the cargo area, then the storage space efficiency is improved, but the ramp may interfere with cargo space when in use position
Solution Approach 1:
The ramp is designed to be dynamically positionable, pivoting between a horizontal loading position and a vertical storage position. When not in use, the ramp pivots vertically along the sidewall to minimize space occupation. The design allows the ramp to be deployed only when needed, providing adaptability for different cargo configurations while maintaining storage efficiency
3Volume of moving object
If the ramp is secured in a vertical orientation along the sidewall, then the ramp footprint is minimized during storage, but the ramp requires additional securing mechanisms
Solution Approach 1:
The pivot connection serves a dual function: it allows the ramp to rotate between positions and simultaneously provides the securing mechanism for vertical storage. The connection point on the sidewall acts as both the rotation axis and the securing anchor, eliminating the need for separate securing mechanisms while maintaining minimal footprint during storage

AI summary
A loading ramp assembly is configured for attachment in a cargo area, and a movable cargo transport includes the cargo area. The cargo area includes a floor, a first sidewall disposed transverse to the floor and a second sidewall disposed transverse to the floor. The first and second sidewalls are spaced apart and generally align with each other. The loading ramp assembly includes a ramp pivotable inside the cargo area relative to the floor between a use position in which at least a portion of the ramp is disposed in a generally horizontal orientation on top of the floor and a storage position in which the ramp is spaced from the floor and secured in a generally vertical orientation along at least one of the first and second sidewalls.
