RV Stabilizer Locking Structure for Secure Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizers for recreational vehicles lack effective mechanisms for securely locking the height adjustment mechanism, leading to potential instability and accidental lowering during use.
Innovation Solution
A stabilizer design featuring a first support structure with an outer tube and a second support structure, including side support bars and connecting rods, combined with a locking mechanism comprising a first, second, and third locking mechanism to securely lock the height adjustment in place, utilizing limit members, racks, and locking pins to prevent unwanted movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to secure the height adjustment, then the stability and reliability are improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to automatically engage and lock the casing at selected height positions without requiring external locking devices or complex control systems. The limit members and locking pins work passively to maintain the locked state, making the system self-sufficient and reducing overall device complexity.
Solution Approach 2:
The locking mechanism is divided into discrete functional components: limit members fixed on the outer tube, movable locking pins in the housing, and corresponding engagement features on the casing. This segmentation allows each component to perform its specific function independently, simplifying the overall design while ensuring reliable locking.
2Adaptability or versatility
If the casing is made slidable for height adjustment, then the adaptability is improved, but the stability during adjustment deteriorates
Solution Approach 1:
The casing is designed to be dynamically adjustable, allowing smooth sliding along the outer tube for height adaptation. The locking mechanism complements this by providing static stabilization at selected positions, creating a system that transitions between dynamic adjustment and static locking states as needed.
Solution Approach 2:
The limit members are pre-positioned at specific height intervals on the outer tube before the casing reaches them. When the casing slides to these predetermined positions, the locking pins automatically engage with the limit members, providing preliminary stabilization without requiring active control or user intervention during the adjustment process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The locking mechanisms ensure stable and secure height adjustment, preventing accidental lowering and enhancing the overall stability and usability of the stabilizer.
Implementation Method 1
the second limit member is selectively abutted against the first limit member, so as to lock a degree of freedom of the casing in the first direction
Implementation Method 2
a casing, slidably sleeved to an outer side of the outer tube
Implementation Method 3
at least three side support bars, a first end of each of the at least three side support bars being hinged with an outer wall of the casing respectively; and at least three connecting rods

AI summary
A stabilizer for a recreational vehicle includes a first support structure, a second support structure, and a locking mechanism. The first support structure includes an outer tube. The second support structure includes a casing, side support bars, and connecting rods. The casing selectively moves in a first direction of a first end of the outer tube or in a second direction of a second end of the outer tube. The locking structure includes a first limit member and a second limit member. The second limit member is selectively abutted against the first limit member, so as to lock a degree of freedom of the casing in the first direction.
