Solution Overview

Problem

Existing sports shoes lack the ability to adjust the rocker point to accommodate individual athlete needs, which is crucial for optimizing performance and comfort in endurance sports.

Innovation Solution

A rocker point adjustment element comprising segments and guiding means that allow for the movement of the rocker point along a path, enabling precise adjustment to individual athlete needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If shoes are produced for mass market with fixed rocker point position, then manufacturing cost and simplicity are improved, but individual athlete performance optimization deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidindividual athlete adaptation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic rocker point adjustment mechanism that allows the rocker point position to be changed after manufacturing. The adjustment element can be moved along a path between different positions (first position near heel, second position near toe) to adapt to individual athlete needs, transforming a static shoe structure into a dynamic one that can be customized without requiring different manufacturing processes for each configuration.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If shoes are customized for individual athletes with specific rocker point positions, then athlete performance is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveindividual athlete customizationVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment element is divided into segments that can be independently positioned along the path. This segmentation allows for discrete, manageable adjustment positions rather than continuous complex mechanisms. The adjustment element can be selectively positioned at predetermined locations (first position, second position, or intermediate positions) simplifying the overall mechanism while maintaining customization capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary adjustment element that mediates between the fixed shoe structure and the variable rocker point requirement. This adjustment element acts as a mediator that can be inserted or repositioned within the shoe's rocker point structure, enabling customization without fundamentally altering the basic shoe design or manufacturing process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the rocker point is fixed in traditional shoe design, then structural simplicity is maintained, but performance optimization for individual gait patterns is lost

Engineering Contradiction:
Improvestructural simplicityVSAvoidperformance consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The invention transforms the static rocker point into a dynamic, adjustable feature. The adjustment element can be repositioned along a defined path to match individual athlete gait patterns, ensuring that the shoe maintains optimal performance characteristics for each user while preserving the overall structural simplicity of the shoe design.

Inventive Principle:
Principle #15Dynamics
