Motorcycle Trailer Hitch Leveling Assembly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle trailer hitches fail to effectively level trailers, leading to instability and potential lifting of attached motorcycles during cargo transport.
Innovation Solution
A motorcycle trailer hitch design comprising a pair of sides with specific dimensional relationships and a bridge piece, allowing for selective engagement with a trailer tongue and standard ball coupler, which elevates the ball coupler relative to the trailer tongue to prevent lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a standard ball coupler is directly attached to the trailer tongue, then the device complexity is reduced, but the trailer stability deteriorates due to lifting during cargo transport
Solution Approach 1:
The patent introduces an intermediary leveling assembly that fits between the trailer tongue and the ball coupler. This intermediate device includes a pair of sides with bridge pieces that engage the tongue and upper sections that engage the ball coupler, preventing direct attachment and eliminating the lifting problem while maintaining reasonable complexity through modular design
2Stability of the object's composition
If the ball coupler is elevated relative to the trailer tongue, then the trailer stability is improved by preventing motorcycle lifting, but the device complexity increases due to additional components
Solution Approach 1:
The leveling assembly is segmented into distinct functional components: a pair of sides with lower sections engaging the tongue, angled sections for structural support, and upper sections with bridge pieces engaging the ball coupler. This segmentation allows each part to perform its specific function while maintaining overall stability without excessive complexity
3Stability of the object's composition
If a leveling assembly with specific dimensional relationships is used, then the alignment and stability are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies particular dimensional parameters for the leveling assembly, including the distance between inner faces of the lower sections and the distance between outer faces of the upper sections, both conforming to the trailer tongue width. These parameter specifications ensure proper alignment and stability while providing clear manufacturing guidelines

AI summary
A motorcycle trailer hitch leveling apparatus for leveling a motorcycle trailer hitch includes a pair of sides each having a lower section, an angled section, an upper section, an inner face, and an outer face. The inner face of the lower section of each side is a first distance apart equaling a second distance between the outer face of the upper section of each side. The first distance and the second distance substantially conform to a width of a trailer tongue. The lower section of each of the pair of sides is configured to selectively engage with the trailer tongue and the upper section of each of the pair of sides is configured to selectively engage with a standard ball coupler. A bridge piece is coupled between the upper section of each of the pair of sides.
