Inline Skate Adjustable Shock Absorber

Solution Overview

Problem

Conventional inline skates lack shock absorbers, resulting in increased shock and jarring when moving on irregular surfaces, which decreases skating speed and causes discomfort to the user's knees and legs.

Innovation Solution

An inline skate design featuring two shock absorbers between the front and rear wheel mounts, utilizing a suspension system with adjustable damping forces through threaded members and torsion springs, allowing users to adjust the shock absorption horizontally and vertically for optimal comfort.

Engineering Contradictions & Design Principles

1Object-affected harmful factors

If no shock absorber is provided in conventional inline skates, then the structure remains simple, but shock and jarring increase greatly when moving on irregular surfaces

Engineering Contradiction:

Improveshock and jarringVSAvoidstructure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shock absorption system is divided into multiple independent shock absorbers (front and rear) rather than using a single complex system. Each shock absorber is a separate component that can be individually adjusted, allowing the skater to customize the shock absorption characteristics for different riding conditions without creating an overly complex integrated system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The shock absorbers incorporate adjustable damping mechanisms that allow the user to dynamically change the shock absorption characteristics based on riding conditions. The damping force can be modified by adjusting the position of damping members within the shock absorber, enabling adaptation to different surface irregularities and skating styles.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If shock absorbers are added to reduce shock and jarring, then comfort and skating speed improve, but the device complexity increases
