Trailer Hitch Step Clamping Structure to Prevent Wobble
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a trailer hitch step that can be firmly retained on an insertable hitch and a hitch receiver assembly in existing technologies.
Innovation Solution
A trailer hitch step comprising a platform with a base tube, notched steps, and a retention plate, along with a securement yoke featuring a base member and threaded fastener, which securely attaches to the hitch insert and receiver assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a trailer hitch step is attached to a hitch receiver assembly, then it provides a stepping platform for accessing the trailer, but it may experience axial movement or wobble without proper securement
Solution Approach 1:
The attachment system is divided into separate functional components: a retention plate that interfaces with the hitch receiver, a securement yoke that clamps onto the hitch insert, and a stepped platform. This segmentation allows each component to perform its specific function optimally while working together as a unified attachment system.
Solution Approach 2:
The retention plate acts as an intermediary element between the hitch receiver assembly and the stepped platform. It provides a stable mounting surface and interfaces with both the receiver tube and the platform structure, ensuring firm retention while distributing mechanical loads effectively.
2Ease of manufacture
If the hitch step is designed with a simple structure, then it is easier to manufacture and install, but it may not provide sufficient securement against axial movement
Solution Approach 1:
The securement yoke incorporates a dynamic clamping mechanism with adjustable fasteners that can be tightened to accommodate different hitch insert dimensions. This allows the same basic structure to securely attach to various insert sizes while maintaining resistance to axial movement and wobble.
Solution Approach 2:
The attachment system utilizes composite construction combining metal components (retention plate, securement yoke, fasteners) with the existing hitch receiver assembly. This composite approach leverages the strength of the vehicle's factory-installed hitch while adding the securement mechanism, achieving high reliability without overly complex manufacturing.

AI summary
A trailer hitch step preferably includes a trailer hitch step platform and a securement yoke. The trailer hitch step platform preferably includes a base tube, a first step, a second step and a retention plate. Each step includes a plate that is notched in a perimeter and then bent over. A rear and bottom of the first and second steps are attached to first and second ends of the base tube. The retention plate includes a securement opening and a receiver opening. A bottom of the retention plate is attached to a top of the base tube. The securement yoke preferably includes a base member and a threaded fastener. The base member includes a base plate and a pair of projections. A clearance notch is formed in one end of the base plate and a threaded tap is formed through an opposing end of the base plate.
