Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric scooters have a fixed damping stroke that cannot be adjusted to meet the needs of different users, affecting stability and comfort.
Innovation Solution
A damping mechanism with an elastic cushion assembly, a coupling arm, and a locking assembly that allows adjustment of the damping stroke by changing the angle of the coupling arm relative to the horizontal plane, enabling users to customize the damping effect based on their weight and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed damping stroke is used, then the structure is simple, but it cannot accommodate varying user needs and weights
Solution Approach 1:
The damping mechanism transforms from a fixed static structure to a dynamic adjustable one by introducing a locking assembly with multiple locking positions. The coupling arm can be rotated to different angles and locked at various positions, allowing the damping stroke to be adjusted according to different user weights and needs, while maintaining structural simplicity through the modular locking mechanism.
Solution Approach 2:
The invention changes the geometric parameter of the coupling arm angle relative to the horizontal plane to adjust the damping stroke. By providing multiple locking positions at different angles, the system allows users to modify the damping characteristics without changing the overall structure, achieving adaptability through parameter variation.
2Adaptability or versatility
If the coupling arm angle is changed to adjust damping stroke, then user needs are met, but the locking mechanism becomes more complex
Solution Approach 1:
The locking assembly is segmented into distinct functional components: a positioning member with multiple positioning holes, a locking member with corresponding locking holes, and an elastic component. This segmentation allows the complex locking function to be achieved through simple, discrete elements that are easy to operate and maintain.
Solution Approach 2:
The elastic component automatically engages the locking member with the positioning member when the coupling arm is rotated to a desired angle, providing self-locking functionality. This self-service mechanism eliminates the need for additional fasteners or complex locking procedures, making the operation simple while achieving multiple adjustable positions.

AI summary
A damping mechanism and a vehicle are provided. The damping mechanism includes: a spindle (10); an elastic cushion assembly (20) used to couple the spindle (10) and the vehicle body; a coupling arm (30) having a first end used to be fixedly coupled to an axle of the wheel and a second end pivotally coupled to the spindle (10); and a locking assembly (40) provided between the coupling arm (30) and the spindle (10) and used to switch the coupling arm (30) and the spindle (10) between at least two locking states and a unlocking state. In the unlocking state, the coupling arm (30) is rotatable, and in the locking states, the coupling arm (30) is locked; in each of the locking states, the coupling arm (30) is in different locking positions; and when in different locking positions, the coupling arm (30) is at different angles to a horizontal plane.
