Tailgate Ramp With Folding Storage Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tailgate systems for pickup trucks lack efficient and space-saving solutions for loading and unloading larger cargo items like motorcycles and ATVs, as they do not provide adequate support and storage for folding ramps.
Innovation Solution
The design includes a tailgate with folding left and right ramps that can form inclined planes, a Z-bracket for support, and side braces for stability, allowing the ramps to be stored within the tailgate when not in use and easily unfolded for use, with a cavity system for storage and a hinged cover to retain the ramps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If folding ramps are provided for loading cargo, then cargo loading capability is improved, but device complexity increases due to additional components and storage requirements
Solution Approach 1:
The ramp assembly is merged with the tailgate structure, where the ramps are stored within a cavity formed in the tailgate itself. This integration eliminates the need for separate storage mechanisms and reduces overall system complexity while maintaining cargo loading capability.
Solution Approach 2:
The tailgate serves multiple functions: it acts as the rear closure of the truck bed and simultaneously houses the storage cavity for the ramp assemblies. This multi-functionality reduces the need for additional components, thereby reducing device complexity while improving adaptability for cargo loading.
2Area of stationary object
If ramps are made foldable for storage, then space efficiency is improved, but reliability decreases due to additional joints and potential failure points
Solution Approach 1:
The ramp assembly is divided into multiple sections connected by hinges, allowing it to be folded into a compact configuration for storage within the tailgate cavity. This segmentation enables space-efficient storage while maintaining structural integrity through the hinge connections.
Solution Approach 2:
The folded ramp assembly is nested within the tailgate cavity, with the ramp sections folded concentrically to minimize storage space requirements. This nesting approach maximizes space efficiency while keeping the ramp structure protected and secure during storage.
3Stability of the object's composition
If Z-brackets and side braces are added for support, then structural stability is improved, but device complexity increases
Solution Approach 1:
Z-brackets and side braces are strategically positioned at critical locations on the ramp assembly where structural support is most needed. This localized reinforcement provides maximum stability with minimal additional components, avoiding unnecessary complexity in areas where support is not required.
Solution Approach 2:
The Z-brackets and side braces are pre-positioned and integrated into the ramp assembly design, ensuring that structural support is already in place before the ramp is deployed. This preliminary structuring eliminates the need for additional stabilization components during operation, reducing overall device complexity.

AI summary
The tailgate ramp includes a tailgate, a left ramp, and a right ramp. The left ramp and the right ramp may be operable to form inclined planes extending from the ground to a truck bed of a pickup truck or from the ground to the tailgate of the pickup truck. A cargo may be moved between the pickup truck and the ground by advancing the cargo over the left ramp and the right ramp. As non-limiting examples, the cargo may be a motorcycle, an ATV, or a lawnmower. Folding ramp assemblies of the left ramp and the right ramp may be folded and stored within a ramp storage cavity of the tailgate when not in use. The folding ramp assemblies of the left ramp the right ramp may be removed from the tailgate and unfolded for use.
