Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-wheeled motorcycles with dual front wheels experience handlebar shake during operation, causing discomfort to riders, especially in certain driving conditions, and there is a need for a solution to reduce this instability.
Innovation Solution
A kit featuring a linear steering stabilizer with a cylinder member and piston rod, along with affixable brackets to the frame and steering components, which dampens handlebar shake by providing damping resistance and preventing handlebar pull-away on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a linear steering stabilizer with piston rod and cylinder member is installed, then handlebar shake is reduced, but device complexity increases
Solution Approach 1:
The patent introduces a linear steering stabilizer as an intermediary component between the steering column and the dual front wheels. This stabilizer includes a piston rod that slides within a cylinder member, creating a damping mechanism that mediates the interaction between steering inputs and wheel movement, thereby reducing handlebar shake without requiring complex active control systems
Solution Approach 2:
The steering stabilizer operates as a self-regulating passive damping system. The piston rod and cylinder member configuration automatically provides damping resistance based on the relative motion between the steering column and wheels, eliminating the need for external power sources or complex control algorithms while effectively reducing handlebar instability
2Stability of the object's composition
If damping resistance is provided by the stabilizer, then handlebar shake is reduced, but force resistance increases
Solution Approach 1:
The linear steering stabilizer changes the dynamic parameters of the steering system by introducing velocity-dependent damping. The damping force varies with the rate of steering movement, providing stronger resistance during rapid oscillations (shimmy) and weaker resistance during steady steering inputs, thereby stabilizing the handlebar while minimizing impact on normal steering operation
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
Effectively reduces handlebar shake and pull-away, enhancing rider comfort and stability on three-wheeled motorcycles, including those without power steering, by stabilizing the steering mechanism during operation.
Implementation Method 1
A portion of the piston rod fits slidingly in the cylinder member. The piston rod terminates in a connecting end. A body bracket is attached to the cylinder member. A first bracket is affixable to the frame and is affixable to the connecting end of the piston rod of the linear steering stabilizer.
