Adjustable Ball Mount Structure Without Strength-Reducing Pin Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ball mounts suffer from reduced structural strength due to pin holes, leading to deformation and breakage during towing, and they often require time-consuming and laborious ball replacement for different sizes.
Innovation Solution
A multifunctional ball mount with a high structural strength is designed, featuring a positioning mechanism with a first positioning pin, positioning through hole, and positioning grooves, which eliminates the need for pin holes on the first mount body, allowing for secure and stable engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pin holes are provided on the first mount body for inserting positioning pins, then positioning between the first mount body and second mount body is achieved, but the structural strength of the first mount body is reduced, making it prone to deformation and breakage during towing
Solution Approach 1:
The invention extracts the positioning function from the first mount body by providing positioning grooves on the second mount body that engage with positioning pins on the sliding block. This removes the need for pin holes in the first mount body, preserving its structural integrity while achieving reliable positioning through the extracted positioning mechanism on the second mount body.
2Device complexity
If the tow ball has a single size, then the structure is simple, but ball replacement for different sizes is time-consuming and laborious, reducing user experience
Solution Approach 1:
The invention makes the second mount body universal by enabling it to accommodate multiple sizes of tow balls through the adjustable positioning mechanism. The positioning grooves and pins allow the second mount body to be positioned at different locations on the first mount body, supporting various ball sizes without requiring separate mount bodies, thus achieving multi-functionality while maintaining structural simplicity.

AI summary
A multifunctional ball mount with a high structural strength includes a first mount body and a second mount body. The first mount body is configured to be connected to a towing vehicle, and the second mount body is slidably provided on the first mount body to adjust a height position of the second mount body. The second mount body is provided with a tow member. A positioning mechanism is provided between the first mount body and the second mount body. The second mount body is positioned with the first mount body through the positioning mechanism. The positioning mechanism includes a first positioning pin, a positioning through hole, and positioning grooves. The positioning through hole and the positioning grooves correspond to the first positioning pin. The positioning through hole is located on the second mount body. There are a plurality of positioning grooves located on the first mount body.
