Recessed Clamping Bolt Attachment for Sway Control Hitch Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer hitch systems fail to effectively reduce trailer sway and achieve load equalization, leading to safety concerns such as loss of steering control and hitch dragging due to uneven weight distribution and sway issues during towing.
Innovation Solution
A trailer hitch system featuring a spring bar support member with adjustable mounting studs and a clamp-type assembly, which provides variable height adjustment and supports spring bars to apply an upward force on the hitch head, thereby reducing sway and equalizing load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid bracket members are used to join spring bars to the trailer tongue, then structural strength is improved, but adaptability and ease of adjustment deteriorate
Solution Approach 1:
The bracket assembly incorporates adjustable components including a vertically adjustable support bar with multiple positioning holes and a rotatable clamp mechanism. This allows the bracket to adapt to different trailer configurations and load requirements while maintaining structural integrity through secure fastening at selected positions.
Solution Approach 2:
The design enables parameter adjustment by providing multiple hole positions along the support bar for varying vertical heights, and allowing rotational adjustment of the clamp angle. These parameter changes permit optimization of the bracket's performance for different towing conditions without compromising structural strength.
2Ease of manufacture
If fixed mounting positions are used for spring bars, then manufacturing simplicity is improved, but adaptability to different trailers deteriorates
Solution Approach 1:
The bracket assembly is divided into modular components: a base plate with pre-drilled mounting holes, a support bar with multiple positioning holes, and a clamp mechanism. This segmentation allows each component to be manufactured independently with standard tolerances while the assembled unit provides adjustable positioning to accommodate various trailer tongue configurations.
3Device complexity
If spring bars are positioned at fixed heights, then device complexity is reduced, but load equalization capability deteriorates
Solution Approach 1:
The support bar features multiple vertically spaced positioning holes that allow adjustment of the spring bar height. This dynamic positioning capability enables precise load equalization for different trailer weights and configurations, while the simple hole-and-pin adjustment mechanism keeps the device complexity low and easy to operate.

AI summary
A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may be attached to a hitch head using a trunnion style connection. The spring bars may be attached to the trailer using rigid brackets that reduce swinging of the spring bars. The rigid brackets having a plurality of contact points may include an upward extending portion for attaching to the trailer tongue, and a lateral extending portion for receiving the spring bars thereupon.
