Vehicle Ramp Connector With Interference Fit Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ramp connection systems for vehicles are unstable at angles greater than 60 degrees and lack effective storage solutions, leading to ramp dislodgment during transport and potential damage.
Innovation Solution
A ramp member with a connector element featuring a mounting channel and a connection panel with a complementary rail, allowing for secure attachment and storage through a C-shaped connector that engages with a connection rail, providing stability and versatility in positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ramp connections are used, then the ramp can be easily attached to the tailgate, but the connection becomes unstable at angles greater than 60 degrees and the ramp may dislodge
Solution Approach 1:
The connection system is divided into separate components: a connection member with a channel and a connector element with a protrusion. This segmentation allows the components to engage through interference fit while maintaining ease of attachment and providing reliable stability through the geometric interlocking mechanism.
Solution Approach 2:
The connection geometry employs asymmetric features including a non-circular channel cross-section and a shaped protrusion that fits specifically into the channel. This asymmetry prevents rotation and dislodgment while maintaining straightforward attachment, resolving the contradiction between ease of operation and connection reliability.
2Ease of operation
If ramps are left in the truck bed for transport, then they are readily available for use, but they can fall off, become lost, or damage equipment being transported
Solution Approach 1:
The connection member serves multiple functions: it provides a secure attachment point for the ramp during loading operations and simultaneously serves as a storage mechanism during transport. The same structural features that enable reliable connection also enable secure retention during transport, eliminating the need for separate storage solutions and preventing damage to transported equipment.
3Adaptability or versatility
If the ramp connection allows various positioning angles, then the ramp is versatile for different loading scenarios, but the connection may become unstable at extreme angles
Solution Approach 1:
The connection system is designed to be dynamic rather than rigidly fixed at a single angle. The interference fit connection allows the ramp to pivot and assume various angles during loading operations while maintaining stable engagement. The geometric interlocking provides continuous stability across a range of positions, enabling versatility without sacrificing connection reliability.

AI summary
A ramp member is disclosed that cooperates with a connection member mounted to a portion of a vehicle, such as a tailgate. The ramp member comprises a first ramp section defining a connection end and a connector element fixedly secured to the connection end. The connector element defines a mounting channel that is configured to engage the connection member mounted to the vehicle. An opening to the mounting channel that has a width smaller than a width of the mounting channel to selectively secure the ramp member to the connection member.
