Solution Overview

Problem

Current athletic training systems primarily provide basic training information such as speed and distance, but fail to offer detailed biofeedback necessary for improving running form and technique, leading to potential injuries and inefficiencies.

Innovation Solution

A system comprising a sensing unit attachable to a runner's shoe, equipped with gyroscopic sensors and processors to monitor foot movement, transmit data to a receiver, and provide real-time biofeedback through visual, auditory, or tactile signals, helping runners adjust their foot strike, cadence, and posture for improved form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If basic training systems (accelerometers, GPS) are used to track distance and speed, then the device complexity is low and ease of operation is high, but the measurement precision of athletic performance characteristics is insufficient and detailed biofeedback cannot be provided

Engineering Contradiction:
Improvefoot strike location measurement precisionVSAvoidsensing unit complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical acceleration sensors with gyroscopic sensors that utilize angular velocity measurement and centrifugal force principles. This substitution enables precise measurement of foot strike location, cadence, and posture by detecting rotational motion characteristics rather than relying on basic acceleration data, thereby achieving high measurement precision while maintaining practical device complexity

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

Solution Approach 2:

The patent introduces a specialized sensing unit as an intermediary component that attaches to the shoe and contains gyroscopic sensors, processors, and transmitters. This intermediary device bridges the gap between simple tracking systems and complex laboratory-grade motion analysis equipment, providing detailed biofeedback capabilities through a wearable interface that processes angular velocity data to determine athletic performance characteristics

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If detailed biofeedback systems with multiple sensors are implemented, then the information completeness for improving running form is enhanced, but the use of energy by the device increases and battery life decreases

Engineering Contradiction:
Improvebiofeedback information completenessVSAvoiddevice energy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent extracts and isolates only the essential sensing components (gyroscopic sensors) needed to measure the three critical athletic performance characteristics (foot strike location, cadence, posture). By removing unnecessary sensors and processing elements found in comprehensive motion capture systems, the device provides complete biofeedback information for running form improvement while minimizing energy consumption through targeted measurement of angular velocity parameters

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sensing unit incorporates an on-board processor that autonomously analyzes angular velocity data to determine foot strike location, cadence, and posture without requiring continuous external processing. This self-service capability reduces the energy burden on the transmitting and receiving systems, allowing the device to maintain complete biofeedback functionality while operating on battery power throughout training sessions

Inventive Principle:
Principle #25Self-service

3Measurement precision

If gyroscopic sensors are used to measure angular velocity and determine foot strike location, then the measurement precision of athletic performance characteristics is improved, but the device complexity and difficulty of detecting and measuring increase

Engineering Contradiction:
Improveathletic performance characteristic precisionVSAvoidangular velocity data processing difficulty
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements a feedback system where the sensing unit transmits processed performance characteristic data to a remote receiver that provides visual, auditory, or tactile feedback to the athlete. This feedback loop converts complex angular velocity measurements into intuitive biofeedback signals (such as metronome rhythms for cadence or visual indicators for foot strike location), making the difficult-to-measure parameters accessible and actionable for running form improvement without requiring the athlete to directly interpret raw sensor data

Inventive Principle:
Principle #23Feedback
