Hitch Ball Hook Assembly With Holding Jaw for Stable RV Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hitching hook devices for recreational vehicles (RVs) suffer from instability due to concentrated carrying capacity on the rear bumper of the hitching vehicle, loose connections between the hitch ball pendant and the hitch arm body, and inflexible assembly and disassembly processes, leading to safety concerns and low work efficiency.
Innovation Solution
A hitch ball hook device with a hitch ball pendant and a hitch arm body, connected via a square steel to a vehicle receiver, featuring a hitch ball seat with a holding jaw and a vertical groove in the hitch arm body for secure connection, along with latches, tightening screws, and rubber rings for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the carrying capacity is concentrated at a point on the rear bumper of the hitching vehicle, then the structure is simple, but the connection stability is low
Solution Approach 1:
The hitch arm body is divided into multiple components including side walls, vertical grooves, and mounting brackets that distribute the connection points across the rear bumper. This segmentation allows the carrying capacity to be distributed rather than concentrated at a single point, improving connection stability while maintaining reasonable structural complexity.
2Ease of manufacture
If the connection between the hitch ball pendant and the hitch arm body is loose, then the assembly is easy to manufacture, but the safety during use is compromised
Solution Approach 1:
The holding jaw is pre-formed with a specific geometry that complements the vertical groove in the hitch arm body. This preliminary shaping ensures that when the components are assembled, they naturally fit together tightly without requiring complex fastening operations, thus maintaining ease of manufacture while achieving safe, gap-free connection.
3Stability of the object's composition
If the hitching hook device is not flexible for assembly and disassembly, then the structure is stable, but the work efficiency is low
Solution Approach 1:
The connection mechanism incorporates movable elements such as the holding jaw that can be positioned and locked into place. This dynamic design allows the device to be easily assembled and disassembled by simple operations while maintaining stable connection when installed, thus improving work efficiency without compromising structural stability.
