Adjustable Truck Ramp for Loading ATVs Without Trailer Disconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a ramp apparatus that allows users to directly load an ATV into the bed of a pickup truck without disconnecting the trailer, and which accommodates different lengths and configurations of trailer tongues.
Innovation Solution
A truck ramp system comprising a first ramp with one end extending into the trailer and the other end detachably secured to the trailer's horizontal rail, a second ramp pivotally secured to the first ramp, and an inner ramp that slides within the second ramp to adjust its length, allowing it to reach the tailgate of the truck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length ramp is used to load ATVs from trailers to trucks, then the loading path is stable and simple, but it cannot accommodate different trailer tongue lengths and configurations
Solution Approach 1:
The ramp is divided into multiple segments (first ramp portion, second ramp portion, third ramp portion) that can be independently positioned and connected. This segmentation allows each segment to be adjusted to accommodate different trailer configurations while maintaining overall structural stability.
Solution Approach 2:
The ramp incorporates movable and adjustable components including telescoping sections, pivot points, and extendable portions that allow the ramp to dynamically adapt its length and angle. This dynamic capability enables the same ramp to work with various trailer tongue lengths without requiring multiple fixed-length ramps.
2Productivity
If the trailer is disconnected from the pickup truck to load an ATV into the truck bed, then a simple ramp can be used, but the loading process becomes time-consuming and inefficient
Solution Approach 1:
The ramp system is designed to perform multiple functions: it can be configured to load ATVs directly from the trailer to the truck bed while the trailer remains attached, or it can be used when the trailer is disconnected. This multi-functionality eliminates the need to disconnect the trailer for loading, significantly improving productivity.
Solution Approach 2:
The ramp acts as an intermediary structure that bridges the gap between the trailer and truck bed, enabling direct loading without requiring trailer disconnection. The ramp's ability to span different distances and angles makes it possible to load ATVs efficiently while maintaining the trailer-truck connection.
3Adaptability or versatility
If a telescoping ramp mechanism is used to adjust ramp length, then the ramp can accommodate different trailer configurations, but the mechanism complexity and potential failure points increase
Solution Approach 1:
The ramp employs dynamic adjustment mechanisms including telescoping sections with locking features and pivot points that allow length and angle adjustment. These mechanisms provide the necessary adaptability while incorporating safety features to maintain reliability during operation.
Solution Approach 2:
The ramp design includes built-in safety features such as locking mechanisms, support legs, and stable base structures that prevent failure before it occurs. These preventive measures ensure that the telescoping and adjustable components operate reliably without sudden failures.

AI summary
A ramp system for transporting a vehicle between a trailer and a truck includes a first ramp having a first end extending into the trailer and a second end configured to be detachably secured to a horizontal rail of the trailer, a second ramp that can be pivotally secured to the first ramp, and a hinge assembly including a first ramp knuckle disposed on the first ramp, a second ramp knuckle disposed on the second ramp, and a hinge pin configured to be disposed through a first ramp bore and a second ramp bore to pivotally secure the second ramp to the first ramp. The second ramp can pivot via the hinge assembly between an open and a stowed position. The ramp system can include an inner ramp configured to slidingly engage with the second ramp between a retracted position and an extended position.
