Solution Overview

Problem

Current footwear designs lack effective mechanisms to enhance proprioceptive and kinesthetic skills and neuromuscular control, as they often rely on single protrusions or simplistic sole maps, which limit the range and precision of foot positioning and orientation during movement.

Innovation Solution

The development of footwear with bulbous protrusions that can be moved and aligned using a protuberance coordinate system, featuring anterior, posterior, medial, and lateral shifts, integrated with an outsole map that includes coordinate systems and markers for precise positioning, allowing for customizable alignment and orientation to enhance proprioception and kinesthetic awareness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single protrusion is used on the footwear sole, then the device complexity is reduced, but the proprioceptive and kinesthetic training effectiveness is limited

Engineering Contradiction:
Improvestructure complexityVSAvoidproprioceptive training effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The single protrusion is segmented into multiple protrusions (first protrusion and second protrusion) positioned at different locations on the sole. Each protrusion can be independently adjusted along its respective adjustment line, allowing for differentiated stimulation of proprioceptive receptors while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protrusions are made adjustable along adjustment lines rather than being fixed in position. This dynamic capability allows the user to modify the position, orientation, and spacing of protrusions based on training requirements, significantly enhancing proprioceptive and kinesthetic training effectiveness without substantially increasing device complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If fixed position protrusions are used, then the ease of operation is improved, but the adaptability for different training needs is reduced

Engineering Contradiction:
Improveease of useVSAvoidtraining program adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The protrusions are designed to be adjustable along adjustment lines marked on the sole. Users can easily reposition protrusions to different locations and orientations according to specific training requirements, providing high adaptability for different proprioceptive and kinesthetic training programs while maintaining simple operation through direct placement and alignment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable protrusion system serves multiple training functions by allowing different configurations. The same footwear can accommodate various training scenarios (balance training, gait retraining, posture correction) by simply repositioning the protrusions, eliminating the need for multiple specialized footwear options.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If precise coordinate system alignment is implemented, then the positioning precision is improved, but the device complexity increases

Engineering Contradiction:
Improveprotuberance positioning precisionVSAvoidcoordinate system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Adjustment lines and coordinate markers are pre-marked on the sole during manufacturing. These preliminary markings guide the user in achieving precise protrusion positioning without requiring complex alignment tools or procedures during use. The coordinate system is built into the footwear structure itself, simplifying the positioning process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adjustment lines and coordinate markers serve as intermediaries between the user and the precise positioning requirement. Instead of directly manipulating complex coordinate systems, users align protrusions with the visual guides (adjustment lines), which translate user actions into precise positional relationships based on the underlying coordinate system.

Inventive Principle:
Principle #24Intermediary (Mediator)
