Vertically Adjustable Hitch Step System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hitch/step systems do not allow for safe, convenient, and economical coupling of vehicles to trailers at various heights while providing a supporting platform as a step.
Innovation Solution
A vertically adjustable hitch/step system comprising a receiver housing with a coupling leg, ball mount, and retaining pins, allowing the system to function as both a step in horizontal orientation and a hitch in vertical orientation, with configurations for secure attachment to a standard hitch receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hitch system is designed to provide multiple height configurations for coupling vehicles to trailers, then the adaptability and versatility of the system is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The hitch system employs a telescopic receiver tube with movable inner and outer tubes that can extend and retract to achieve different height configurations. This dynamic structure allows the hitch to adapt to various trailer heights without requiring complex discrete adjustment mechanisms, as the continuous telescopic motion provides smooth height variation.
Solution Approach 2:
The hitch system integrates multiple functions into a single device: it serves as both a coupling mechanism for trailers and a support structure during vehicle operation. The telescopic receiver tube and ball mount assembly can function at different heights for various trailer types while maintaining structural integrity, eliminating the need for separate adjustment devices.
2Ease of operation
If a hitch system integrates a step platform function, then the ease of operation for vehicle access is improved, but the device complexity increases due to additional structural components
Solution Approach 1:
The hitch system merges the step platform function with the ball mount assembly by positioning the ball mount on top of the receiver tube assembly. This integrated structure serves dual purposes: the ball mount provides trailer coupling capability while simultaneously serving as a step platform for vehicle access, eliminating the need for separate step components.
Solution Approach 2:
The receiver tube assembly and ball mount structure are designed to fulfill multiple functions: structural support for the hitch mechanism, height adjustment for different trailers, and a stable platform for stepping during vehicle access. This multi-functionality reduces the overall number of components needed in the system.

AI summary
A hitch/step system which includes a main body that acts as a step when installed in a horizontal position and a vertically adjustable hitch when installed in a vertical position. In addition to a hitch attachments are provided for use with the hitch including a ball mount, a pindle lock and a shackle. The hitch attachments are interchangeable and seperably coupled to the main body and may be removed when not towing and when using as a step. Additional components include interior reflectors and removable LED lights.
