Foldable King Pin Stabilizer for Fifth Wheel Trailer Rocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fifth wheel camper/horse trailers experience instability and rocking due to factors like moderate winds and uneven terrain, leading to discomfort and disturbed sleep, with existing stabilizers consuming storage space and requiring time-consuming installation/removal.
Innovation Solution
A foldable fifth wheel trailer stabilizer device with telescoping legs and adjustable knobs, attached to the king pin box, providing stable support and adjustable height, which can be folded for storage and does not require installation/removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional stabilizers are used to reduce trailer movement, then stability is improved, but storage space is consumed and installation/removal requires time and physical effort
Solution Approach 1:
The stabilizer device is merged with the king pin box assembly, combining the stabilizer mechanism with the existing hitch structure. This integration allows the stabilizer to be permanently mounted on the trailer without requiring separate installation and removal operations, eliminating the time and physical effort associated with conventional stabilizer deployment while maintaining trailer stability.
Solution Approach 2:
The king pin box assembly is designed to serve multiple functions: it provides the hitch connection for towing and simultaneously houses the stabilizer mechanism. This multi-functionality eliminates the need for separate stabilizer units that require installation and removal, as the stabilizer capability is inherent to the king pin box structure itself.
2Stability of the object's composition
If conventional stabilizers are used to reduce trailer movement, then stability is improved, but valuable storage space within the trailer is consumed
Solution Approach 1:
The stabilizer mechanism is merged into the king pin box assembly, eliminating the need for separate stabilizer units that would occupy storage space within the trailer. The stabilizer components are integrated into the external hitch structure, freeing up all interior storage volume while maintaining the stabilizing function.
Solution Approach 2:
The stabilizer mechanism is relocated from the interior storage space to the exterior king pin box assembly. This spatial reconfiguration moves the stabilizer components to a different dimension (external vs. internal space), eliminating the conflict between stabilizer storage and trailer storage capacity.
3Adaptability or versatility
If telescoping legs with adjustable knobs are used, then adaptability to different terrains is improved, but device complexity increases
Solution Approach 1:
The stabilizer legs are designed as telescoping structures with adjustable lengths, allowing dynamic adaptation to different terrain conditions and trailer heights. The adjustable knobs enable users to modify the leg extension to match varying ground levels, providing terrain adaptability while maintaining a relatively simple mechanical structure based on basic telescoping mechanisms.

AI summary
A foldable fifth wheel trailer stabilizer device is disclosed. The device is attached to the trailer's king pin box and features two telescoping legs with adjustable knobs for length adjustment. The legs are equipped with chains for added support and are complemented by adjustable supporting members on the king pin box for support when folded and are not in use. In one embodiment, the device includes an additional telescoping leg connected to a horizontal member that spans the first and second legs. The additional leg is also adjustable in length and can be secured with chains for further support. The device is adaptable to various trailer heights and can be easily folded for convenient storage and transportation.
