Solution Overview

Problem

Existing solutions for providing haptic feedback in running shoes often rely on electronic devices, which are expensive, prone to errors, require maintenance, and can cause discomfort or injury due to hard, stiff pins providing haptic feedback.

Innovation Solution

A sole for a shoe comprising a sole component with loose particles that provide haptic feedback during athletic activities, eliminating the need for electronic components and offering feedback on foot strike, roll-off behavior, stride length, stride frequency, and massage effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electronic devices are used to provide haptic feedback, then feedback functionality is achieved, but cost, complexity, and maintenance requirements increase

Engineering Contradiction:
Improvefeedback functionalityVSAvoidelectronic device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces electronic feedback systems with a purely mechanical haptic feedback system using loose particles. The particles provide tactile feedback through their physical interaction with the foot during running, eliminating the need for sensors, batteries, motors, and electronic control systems while maintaining reliable feedback functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The loose particles automatically provide haptic feedback based on the runner's gait and foot strike patterns without requiring external power sources or electronic control. The system is self-regulating, with particles naturally moving and providing feedback based on the mechanical forces applied during running.

Inventive Principle:
Principle #25Self-service

2Reliability

If hard pins are used for haptic feedback, then feedback is provided, but user comfort decreases and injury risk increases

Engineering Contradiction:
Improvefeedback provisionVSAvoiduser discomfort and injury risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical parameters of the feedback elements from hard, fixed pins to soft, movable loose particles. This transformation alters the interaction characteristics, allowing the feedback elements to conform to the foot's anatomy and movement patterns, thereby providing feedback while maintaining comfort and reducing injury risk.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The loose particles are free to move within the sole structure, allowing them to dynamically adapt to the runner's gait, foot strike location, and pressure distribution. This dynamic behavior enables the particles to provide feedback without creating fixed pressure points that could cause discomfort or injury.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If electronic feedback systems are used, then running technique can be monitored, but cost and maintenance requirements increase

Engineering Contradiction:
Improverunning technique feedbackVSAvoidsystem cost and maintenance
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The loose particles are simple, inexpensive mechanical elements that can be easily manufactured and replaced if needed. Unlike expensive electronic systems, these particles require no complex manufacturing processes, no specialized maintenance, and can be produced at low cost using standard footwear manufacturing techniques.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
