Adjustable Scooter Damping Mechanism With Locking Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric scooters lack an adjustable damping mechanism, which fails to accommodate the varying needs of users with different weights, leading to inadequate stability.
Innovation Solution
A damping mechanism featuring a spindle, elastic cushion assembly, coupling arm, and locking assembly that allows the coupling arm to be adjusted to different angles relative to the horizontal plane, thereby changing the vehicle's height and damping stroke, allowing users to customize the damping effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed damping stroke is used in the damping mechanism, then the structure is simple, but it cannot accommodate varying user needs and weights
Solution Approach 1:
The damping mechanism transitions from a fixed structure to a dynamically adjustable one. The coupling arm can be rotated relative to the spindle to change the damping stroke, and the locking assembly enables switching between locked and unlocked states. This allows the system to adapt to different user needs while maintaining structural simplicity through controlled dynamic adjustment.
Solution Approach 2:
The damping stroke parameter is made adjustable by changing the relative position between the coupling arm and spindle. By rotating the coupling arm to different angles and locking it at desired positions, the damping stroke can be customized for different user weights and preferences, transforming a fixed parameter into a variable one.
2Adaptability or versatility
If the coupling arm is made rotatable relative to the spindle, then the damping stroke can be adjusted, but the mechanism requires additional locking components
Solution Approach 1:
The locking assembly is designed to be operated by the user themselves without requiring external tools or complex mechanisms. The user can lock and unlock the coupling arm at desired positions through simple manual operation, making the system self-servicing and reducing the need for additional complex locking components.
3Adaptability or versatility
If multiple locking positions are provided for the coupling arm, then different damping strokes are achievable, but the manufacturing precision requirements increase
Solution Approach 1:
The continuous rotation range of the coupling arm is segmented into discrete locking positions. Instead of requiring precise continuous positioning, the system provides multiple predetermined locking positions where the coupling arm can be secured. This segmentation approach reduces manufacturing precision requirements while still offering multiple damping stroke options for different user needs.

AI summary
A damping mechanism and a vehicle are provided. The damping mechanism includes: a spindle; an elastic cushion assembly used to couple the spindle and the vehicle body; a coupling arm having a first end used to be fixedly coupled to an axle of the wheel and a second end pivotally coupled to the spindle; and a locking assembly provided between the coupling arm and the spindle and used to switch the coupling arm and the spindle between at least two locking states and a unlocking state. In the unlocking state, the coupling arm is rotatable, and in the locking states, the coupling arm is locked; in each of the locking states, the coupling arm is in different locking positions relative to the spindle; and when the coupling arm is in different locking positions, the coupling arm is at different angles to a horizontal plane.
