Convertible Trailer Hitch Assembly for Multiple Towing Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailer systems are limited to a single type of hitch, requiring multiple trailers and vehicles for tasks that need multiple towing configurations, which is logistically cumbersome, especially for operations far from a base location.
Innovation Solution
A trailer design featuring a convertible hitch assembly with a hitch converter that can switch between over-axle and behind-axle hitch couplers, allowing it to couple with various vehicles and hitches, and includes a ramp system that stows within the trailer for versatile operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a trailer is designed with a single type of hitch, then the structure is simple and easy to manufacture, but it requires multiple trailers to complete tasks needing multiple towing configurations
Solution Approach 1:
The trailer hitch assembly is designed to perform multiple functions by accommodating different hitch types (gooseneck, fifth wheel, pintle, receiver) through a single universal structure. The hitch converter allows the same trailer to couple with various towing systems, eliminating the need for multiple specialized trailers.
Solution Approach 2:
The hitch assembly incorporates convertible components that can be dynamically reconfigured between different hitch types. The hitch converter and interchangeable couplers allow the trailer to adapt its configuration based on the specific towing requirements, transforming from a static single-purpose design to a dynamic multi-purpose system.
2Adaptability or versatility
If multiple trailers are used to accommodate different towing configurations, then each trailer can be optimized for its specific hitch type, but the logistics and routing become cumbersome
Solution Approach 1:
Instead of maintaining multiple specialized trailers for different towing configurations, the invention provides a universal trailer that can handle all hitch types through its convertible hitch assembly. This single versatile trailer replaces multiple specialized vehicles, dramatically simplifying logistics management and routing operations.
3Adaptability or versatility
If a convertible hitch assembly is implemented, then the trailer can accommodate different towing systems, but the hitch assembly structure becomes more complex
Solution Approach 1:
The hitch assembly is divided into modular components including the hitch converter, interchangeable couplers, and mounting structures. This segmentation allows each component to be independently designed and manufactured, making the complex system more manageable while maintaining versatility across different hitch types.

AI summary
A trailer includes a trailer bed, a draw bar assembly, and a convertible hitch assembly. The trailer bed includes a platform and one or more sets of two or more wheels. The draw bar assembly is coupled to the trailer bed. The convertible hitch assembly includes a hitch converter coupled to the draw bar assembly. The convertible hitch assembly includes an over-axle hitch coupler insertable into the hitch converter, wherein the over-axle hitch coupler is mated to an over-axle hitch component coupled to a first vehicle. The convertible hitch assembly includes a behind-axle hitch coupler insertable into the hitch converter, wherein the behind-axle hitch coupler is mated to a behind-axle hitch component coupled to at least one of the first vehicle or an additional vehicle.
