Trailer Sway Bracket With Adjustable Friction Clamp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer hitch sway control systems require drilling into the trailer tongue, use specialized ball mounts, do not provide weight distribution, limit turning radius, and lose effectiveness in wet conditions due to reduced friction.
Innovation Solution
A trailer hitch system utilizing an 'L' bracket with a clamping mechanism and spring arms that apply adjustable frictional force to reduce sway, incorporating friction linings and a resilient member to maintain contact with tapered spring arms, allowing for variable clamping force adjustment and improved weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a telescoping bar with outer tube and clamping mechanism is used for sway control, then sway between towing vehicle and trailer is reduced, but holes must be drilled and tapped into the trailer tongue
Solution Approach 1:
The sway control system is divided into separate components: the L-bracket attaches to the trailer tongue without drilling, while the telescoping bar assembly attaches to the hitch ball. This segmentation allows each component to be installed independently using existing attachment points, eliminating the need to drill into the trailer tongue.
Solution Approach 2:
The system uses a duplicate attachment approach where the L-bracket replicates the ball hitch attachment method by using a separate telescoping bar that connects to the hitch ball in a similar manner, rather than requiring direct attachment to the trailer tongue structure.
2Reliability
If a telescoping bar with clamping mechanism is used for sway control, then sway is reduced, but a specialized ball mount with larger and smaller hitch balls is required
Solution Approach 1:
The L-bracket is designed with a universal interface that can accommodate standard hitch balls while incorporating the telescoping bar mechanism. The bracket structure allows the same assembly to work with different ball sizes and configurations, eliminating the need for specialized ball mounts with multiple hitch balls.
3Reliability
If a telescoping bar sway control device is used, then sway is reduced, but weight distribution is not provided
Solution Approach 1:
The system merges two previously separate functions into a single integrated L-bracket assembly: the sway control telescoping bar mechanism is combined with the weight distribution spring arm structure. This allows the device to simultaneously provide both sway control and weight distribution capabilities through one unified component.
4Reliability
If a telescoping bar sway control device is used, then sway is reduced, but turning radius is limited and disconnection is required for sharp turns
Solution Approach 1:
The L-bracket incorporates a telescoping bar with movable sections that can dynamically adjust their length and position. This dynamic structure allows the sway control mechanism to flex and adapt during sharp turns and backing maneuvers, maintaining connection while accommodating extreme angles without requiring disconnection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces sway between the towing vehicle and trailer, maintains effectiveness in wet conditions, and allows for sharper turns without disconnection, while providing weight distribution benefits.
Implementation Method 1
A resilient member may be installed onto the shaft between the nut and the clamping member. The resilient member may be operable to apply a frictional force to thereby maintain contact with a tapered spring arm.
Data Source
AI summary
An apparatus for reducing sway between a towing vehicle and a trailer is disclosed. The apparatus may comprise a bracket assembly that attaches to a tongue of a trailer. The bracket assembly may include a surface for supporting a spring arm extending from a weight distribution hitch installed on a tow vehicle. The bracket assembly may include a clamp that is able to apply a frictional force to thereby oppose movement of the spring arm. The clamping force applied by the clamp may be variable to ensure proper operation.
