Solution Overview

Problem

Existing buffering elements in footwear, such as springs and air cavities, are ineffective in absorbing forces not in the vertical direction, particularly for large-weight wearers, leading to poor shock absorption and increased risk of ankle sprains.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If conventional buffering elements (springs, air cavities) are used, then vertical shock absorption is achieved, but transverse shock absorption is insufficient

Engineering Contradiction:

Improvevertical shock absorptionVSAvoidtransverse shock absorption

Core Design Contradiction:

ForceVSAdaptability or versatility

Solution Approach 1:

The magnetic shock-absorbing structure is divided into multiple magnetic elements (first magnetic element and second magnetic elements) with different orientations. The first magnetic element provides vertical shock absorption, while the second magnetic elements provide transverse shock absorption. This segmentation allows each component to specialize in a specific direction, resolving the contradiction between vertical and transverse shock absorption capabilities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces magnetic elements oriented in multiple dimensions (vertical and transverse directions) to handle shock forces from different directions. By adding the transverse dimension to the traditional vertical-only buffering approach, the system gains the ability to absorb shock forces in both vertical and transverse directions, effectively resolving the adaptability issue.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Force

If conventional buffering elements are used, then vertical direction buffering is provided, but impact forces not in vertical direction are not effectively absorbed

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the orientation parameter of the magnetic elements to provide buffering in multiple directions. By adjusting the magnetic coupling directions of different elements (vertical for first element, acute angle for second elements), the system can effectively absorb impact forces from various directions, improving reliability for large-weight wearers.

3Adaptability or versatility

If magnetic shock-absorbing structures with multiple orientations are used, then comprehensive shock absorption is achieved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple magnetic elements with different orientations into a single integrated magnetic shock-absorbing structure. The first magnetic element and second magnetic elements are positioned adjacent to each other in the sole structure, working together to provide comprehensive shock absorption in both vertical and transverse directions. This merging approach achieves multi-directional shock absorption without requiring separate complex mechanisms for each direction.
