Fifth Wheel Hitch Mounting With Interlocking Flanges for High Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fifth wheel hitch systems face challenges in distributing load weight evenly, requiring expensive and complex mounting systems for high-load applications, which are difficult for untrained users to install and align.
Innovation Solution
A multi-point connection system using a series of fasteners with interlocking flanges and friction members that engage apertures at different elevations, providing a single shear surface for attachment, allowing for easier alignment and increased clamping force, and enabling modular assembly and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a durable monolithic construction is used for high load hitch assemblies, then strength and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The hitch assembly is divided into separate modular components including a receiver tube, mounting brackets, and fasteners that can be assembled together. This segmentation allows each component to be optimized independently while maintaining overall structural integrity for high load capacities.
Solution Approach 2:
Multiple mounting points and fasteners are combined into a integrated mounting system that distributes loads across multiple attachment points. The mounting brackets combine multiple functions including structural support, alignment features, and load distribution in a single component.
2Strength
If a multi-point connection system is used, then load distribution is improved, but device complexity increases
Solution Approach 1:
The mounting brackets are designed with universal features that serve multiple functions: structural support, load distribution across multiple points, alignment guidance, and easy installation. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The connection system incorporates self-aligning features and friction members that automatically position components correctly during assembly, eliminating the need for complex alignment procedures or specialized tools.
3Force
If friction members are added to fasteners, then clamping force is improved, but device complexity increases
Solution Approach 1:
The friction member is nested within the fastener assembly, with the friction member fitting inside a recess in the mounting bracket. This nested configuration allows the friction member to be integrated into the existing fastener system without adding external complexity.
