Two-Wheeler Suspension with Adjustable Rocker Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suspension systems for two-wheelers lack the ability to manually adjust springing operation and suspension characteristics, failing to provide riders with necessary customization options.
Innovation Solution
A suspension system featuring a swing arm, rocker arm, and length adjustable unit, allowing for manual adjustment of the rocker arm length and shock absorber position via a knob-activated spur gear mechanism, enabling riders to customize suspension characteristics and springing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed suspension system is used, then the structure is simple, but the rider cannot adjust suspension characteristics
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows the rocker arm link length to be changed during operation. The rider can rotate a knob to move the shock absorber mounting point along the rocker arm, thereby adjusting the effective length of the rocker arm link and changing suspension characteristics according to different riding conditions and rider preferences.
Solution Approach 2:
The suspension system is designed with multi-functionality by incorporating an adjustable mechanism that serves both as a structural component and an adjustment mechanism. The same rocker arm structure serves as both the suspension linkage and the adjustment mechanism, allowing one component to perform multiple functions without significantly increasing overall system complexity.
2Adaptability or versatility
If a fixed shock absorber position is used, then the manufacturing is simple, but the springing operation cannot be regulated
Solution Approach 1:
The shock absorber mounting system is segmented into discrete adjustment positions along the rocker arm. The mounting point can be positioned at different locations on the rocker arm, creating distinct springing characteristics. This segmentation allows for regulated springing operation while maintaining relatively simple manufacturing, as the adjustment mechanism uses discrete positions rather than continuous adjustment.
3Ease of operation
If no adjustment mechanism is provided, then the device complexity is low, but the ride comfort cannot be customized
Solution Approach 1:
The suspension system enables self-service adjustment by the rider without requiring external assistance or complex electronic controls. The rider can manually rotate a knob to adjust the shock absorber position and customize the suspension characteristics for different riding conditions, making the system user-friendly and easy to operate.
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
Enables riders to adjust suspension characteristics and regulate rear wheel springing operation, improving ride comfort by allowing customizable shock absorption and vibration reduction.
Implementation Method 1
The shock absorber is configured to absorb vibrations
Implementation Method 2
The rocker arm is configured to transmit force from a wheel to a spring element of a shock absorber
Implementation Method 3
the springing operation of the rear wheel based on the length adjustment of the rocker arm
