Inline Skate Shock Absorber With Adjustable Torsion Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inline skates lack a shock absorber, resulting in increased shock and jarring when moving quickly over irregular surfaces, which can decrease skating speed and cause discomfort to the user's knees and legs.
Innovation Solution
An inline skate design incorporating a shock absorber with a length-adjustable biasing member, comprising a torsion spring, positioned between the front and rear wheel mounts, allowing for adjustable damping force through a threaded adjustment mechanism and bifurcation elements, and a protective member for collision protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If no shock absorber is provided in conventional inline skates, then the structure remains simple and lightweight, but shock and jarring increase greatly when moving quickly over irregular surfaces
Solution Approach 1:
The shock absorber is divided into multiple functional segments: a biasing member (torsion spring) for shock absorption, a threaded adjustment member for damping force control, and positioning members with bifurcation elements for structural integration. This segmentation allows each component to perform its specific function while maintaining overall structural efficiency.
Solution Approach 2:
The shock absorber incorporates a threaded adjustment member that allows dynamic modification of the biasing member length and damping force according to user needs. This dynamic adjustability enables the shock absorption characteristics to be optimized for different skating conditions and user preferences without changing the basic structure.
2Ease of operation
If a shock absorber is added to reduce shock and jarring, then skating comfort improves, but the device complexity increases
Solution Approach 1:
The shock absorber design merges multiple functions into a single integrated assembly: shock absorption, damping force adjustment, and structural mounting. The biasing member, threaded adjustment member, and positioning members work together as a unified system, reducing the need for separate components and simplifying installation while providing comprehensive shock protection.
Solution Approach 2:
The threaded adjustment member enables users to self-adjust the damping force and biasing member length according to their weight and preferences without requiring external tools or complex procedures. This self-service capability enhances user comfort while avoiding the need for additional adjustment mechanisms or professional servicing.
3Adaptability or versatility
If the biasing member length is made adjustable to accommodate different user weights, then adaptability improves, but device complexity increases
Solution Approach 1:
The shock absorber allows adjustment of the biasing member length as a key parameter to accommodate different user weights and preferences. By changing this single geometric parameter through the threaded adjustment member, the system adapts to various users without requiring complete redesign or multiple pre-configured options, maintaining simplicity while achieving versatility.
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
The shock absorber significantly reduces shock and jarring, enhances skating comfort, and accommodates different user weights by adjusting the damping force, while enabling the skate to slide obliquely during collisions.
Implementation Method 1
