Turnable Trailer Ball Head Assembly With Quick-Lock Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailers have fixed ball heads that are difficult to adjust freely, requiring cumbersome disassembly and reassembly for alignment, which is time-consuming and laborious.
Innovation Solution
A ball head turnable trailer with a rotating adjustment assembly featuring a pin sleeve, fixed pin, and reset spring allows for easy adjustment of ball heads by pulling a pull portion to release position limiting, enabling simple and labor-saving rotation without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ball heads are fixed on the trailer arm, then the structure is simple and stable, but the ball heads cannot adjust position and orientation freely, reducing flexibility
Solution Approach 1:
The ball head assembly is designed to rotate around the rotating shaft, transforming a static fixed structure into a dynamic adjustable one. The mounting base can rotate to different angles and positions, allowing the ball heads to adapt to various towing requirements while maintaining structural simplicity through the rotation mechanism
2Adaptability or versatility
If ball heads are made changeable, then flexibility is improved, but the adjusting method becomes cumbersome requiring removal and reinstallation
Solution Approach 1:
The rotating adjustment assembly with fixed pin and reset spring is pre-configured on the mounting base, allowing the ball heads to be adjusted to different positions by simply rotating the mounting base around the rotating shaft. The preliminary setup of the adjustment mechanism eliminates the need for cumbersome removal and reinstallation operations
Solution Approach 2:
The reset spring automatically returns the fixed pin to its original position after adjustment, enabling the user to simply rotate the mounting base to the desired position and release it. The system self-locks into place without requiring manual intervention for locking or tightening, making adjustment simple and labor-saving
3Adaptability or versatility
If ball heads are adjusted by removing and reinstalling, then position change is achieved, but the process is time-consuming and laborious
Solution Approach 1:
The mounting base rotates around the rotating shaft to change ball head positions, replacing the time-consuming removal and reinstallation process with a quick rotation operation. This dynamic adjustment mechanism allows position changes in seconds without any disassembly
Solution Approach 2:
The rotating adjustment assembly with automatic locking through the fixed pin and reset spring mechanism enables rapid position changes. The user only needs to rotate the mounting base to the desired position, and the system automatically locks into place, eliminating time-consuming manual alignment and fastening operations

AI summary
A ball head turnable trailer is provided, including a trailer body and a trailer assembly containing a connecting component and a trailer component. The trailer component includes a mounting base and multiple ball heads. A rotating adjustment assembly includes a pin sleeve, a fixed pin, and a reset spring. A rotating shaft is roundly set with multiple fixed holes, each of which is matched with the fixed pin. A pull portion is pulled outwards to drive the fixed pin to move out from the fixed hole to release position limiting between the mounting base and the rotating shaft. The trailer no longer needs remove the fixed pin, which prevents the fixed pin losing. Moreover, the trailer is simple and labor-saving to pull, which is convenient and efficient.
