Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal mobility devices face challenges with residual vibration removal, complex structure, increased load, durability issues, and poor aesthetics due to their suspension systems, particularly the telescopic and link type suspension structures.
Innovation Solution
A shock absorber structure with a damper that includes a stationary part, a steering part, a sliding part with an internal fluid space, an elastic body, and a flow path for fluid communication, allowing separate control of damping forces and integration with a mobility device to reduce residual vibration and improve aesthetics and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If telescopic type suspension structure is used, then the structure is simple, but residual vibration removal is difficult
Solution Approach 1:
The suspension system is segmented into distinct functional components: spring element for elastic recovery and damper element for vibration damping. This segmentation allows each component to perform its specific function effectively, with the damper providing residual vibration removal that the spring alone cannot achieve.
Solution Approach 2:
A damper element is introduced as an intermediary component between the upper and lower arms. This damper acts as a mediator that dissipates kinetic energy through fluid resistance, effectively removing residual vibrations while the spring handles the elastic support function.
2Force
If link type suspension structure is used, then load transfer is improved, but structure becomes complicated and load increases
Solution Approach 1:
The patent merges the spring element and damper element into a single integrated suspension assembly. This combination achieves effective load transfer through the coordinated action of elastic and damping forces, avoiding the need for complex link-type mechanisms while maintaining load transfer capability.
3Ease of manufacture
If exposed wiring is used in suspension, then installation is easy, but durability and aesthetics are degraded
Solution Approach 1:
The wiring is nested within the suspension structure components, specifically routed through the damper element and connection points. This nesting approach protects the wiring from external damage while maintaining ease of installation through integrated routing paths.

Function Achieved in This Case
The shock absorber structure effectively reduces residual vibration, enhances riding comfort by controlling damping forces, and improves durability and aesthetics by integrating the damper within a simple design.
Implementation Method 1
an elastic body having both ends that are respectively coupled to the steering part and the sliding part to support the steering part and the sliding part and maintain the internal space between steering part and sliding part
Implementation Method 2
a sliding part which forms an internal space containing fluid between the steering part and the sliding part... configured to communicate the internal space between steering part and sliding part with an outside so that the fluid can flow
