Adjustable Hitching Hook Assembly for Stable RV Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hitching hook devices for recreational vehicles have stability issues due to concentrated load on the rear bumper and are inconvenient for assembly and disassembly, leading to low work efficiency.
Innovation Solution
A hitching hook device with a hitching ball body and arm featuring a square steel connection, horizontal clamping grooves, and a latch system that allows for flexible installation and disassembly, including adjustable height and direction, and enhanced stability through multiple clamping grooves and resilient pin connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the carrying capacity is concentrated at a point on the rear bumper, then the structure is simple, but the connection stability is low
Solution Approach 1:
The hitching arm is divided into multiple segments with square grooves at different positions, allowing the load to be distributed across multiple attachment points rather than concentrated at a single point. This segmentation enables both improved stability and manageable structural complexity.
Solution Approach 2:
The invention transitions from a single-point attachment to a multi-point attachment system distributed across different spatial positions on the rear bumper. By adding the dimension of spatial distribution, the load is spread out, improving connection stability without excessively complicating the structure.
2Ease of operation
If the hitching ball body is connected through a pin shaft in a vertical groove, then the structure is simple, but the assembly and disassembly are inconvenient and time-consuming
Solution Approach 1:
The latch mechanism provides dynamic locking and unlocking capability, allowing the hitching ball body to be quickly secured or released from the hitching arm. This dynamic system enables fast assembly and disassembly operations, significantly reducing the time required compared to static pin shaft connections.
Solution Approach 2:
The latch acts as an intermediary mechanism between the hitching ball body and the hitching arm, facilitating quick connection and disconnection. This intermediary component simplifies the operation by providing a dedicated locking/unlocking interface that is easier to operate than direct pin shaft manipulation.
3Adaptability or versatility
If the hitching arm uses a vertical groove with pin shaft connection, then the structure is simple, but the adaptability for different configurations is insufficient
Solution Approach 1:
The hitching arm is designed with multiple square grooves at different positions, making it universal and adaptable to various hitching ball body configurations. This multi-functional design allows the same hitching arm to accommodate different attachment requirements without requiring multiple specialized components, thereby improving adaptability while controlling structural complexity.

AI summary
A new type of a hitching hook device includes a hitching ball body and a hitching arm, the hitching arm includes a square steel configured to connect to a vehicle receiver, and the hitching ball body includes at least one hitching ball. The hitching ball body includes a holding jaw, and at least a horizontal clamping groove is defined on the holding jaw. The hitching arm includes at least two square grooves, a fixing plate is disposed between adjacent two square grooves, and a latch is disposed on a top of the hitching arm. The holding jaw of the hitching ball body is clamped to the fixing plate through the horizontal clamping groove, and the latch extends from the top of the hitching arm to a bottom of the hitching arm by passing through the holding jaw. The hitching hook device is tool with many advantages improving work efficiency.
