Adjustable Stabilizer Bar for Recreational Vehicle Torsion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizer bars for recreational vehicles lack adjustable rigidity, leading to ineffective torsion correction and increased cost and weight when attempting to enhance rigidity, due to fixed support configurations and material thickness.
Innovation Solution
A stabilizer bar system with adjustable support positions and a unique shape that decreases flexural rigidity along its length, allowing for customizable rigidity without increasing weight or cost, featuring a support member that changes the stabilizer bar's position and an arm support member that restricts movement parallel to the arm axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rigidity of the stabilizer bar is increased by using thicker and more rigid materials, then the stabilizer bar can provide better torsion correction, but the cost and weight of the stabilizer bar will increase
Solution Approach 1:
The stabilizer bar employs non-uniform thickness distribution along its length, with thicker sections at support locations and thinner sections in between. This local variation in quality provides high rigidity where needed for torsion correction while reducing overall weight and material cost.
Solution Approach 2:
The invention introduces adjustable support positions for the stabilizer bar, allowing the rigidity characteristics to be dynamically adjusted based on terrain conditions and rider preference. The support member can change the position at which the stabilizer bar is supported, enabling adaptation without changing the physical bar itself.
2Adaptability or versatility
If the support configuration of the stabilizer bar is made fixed, then the structure is simpler, but the rigidity cannot be adjusted according to terrain conditions and rider preference
Solution Approach 1:
The support member is designed to allow adjustment of the stabilizer bar support position along the longitudinal direction of the vehicle. This dynamic capability enables the system to adapt to different terrain conditions and rider preferences while maintaining a relatively simple overall structure.
Solution Approach 2:
The support member serves multiple functions: it supports the stabilizer bar, allows position adjustment, and provides a mechanism for rigidity control. This multi-functionality reduces the need for separate adjustment mechanisms, keeping the device complexity low while achieving high adaptability.
3Ease of operation
If the stabilizer bar is made to slide on lower arms to allow support movement, then the support position can change, but the force received by ground contacting parts cannot be readily transferred to the stabilizer bar
Solution Approach 1:
The arm support member allows the stabilizer bar to pivot in a plane parallel to the arm axis, providing dynamic adjustment capability. This pivoting motion enables effective force transfer from ground contacting parts to the stabilizer bar while maintaining support position adaptability.
Solution Approach 2:
The arm support member acts as an intermediary between the stabilizer bar and the lower arm. It facilitates both force transfer and position adjustment by allowing controlled pivoting motion, resolving the conflict between force transfer efficiency and adjustability.
4Strength
If the stabilizer bar has a simple linear shape, then the manufacturing is easier, but the rigidity is insufficient without increasing material thickness
Solution Approach 1:
The stabilizer bar features a bent shape with varying curvature along its length, creating local variations in rigidity. The bent portions provide enhanced torsion correction capability without requiring increased material thickness, and the shaping process is compatible with standard manufacturing methods.

AI summary
A recreational vehicle includes a vehicle frame, a pair of left and right arms attached to the vehicle frame and extending from the left and right sides of the vehicle frame, a pair of left and right ground contacting parts respectively attached to the pair of left and right arms, and a stabilizer bar for correcting a torsion on the pair of left and right ground contacting parts. The stabilizer bar is provided with a support member capable of changing a position at which the stabilizer bar is supported.
