Solution Overview

Problem

Existing heart rate monitoring systems lack accuracy in determining optimal exercise intensity levels and fat burning rates, as these vary significantly among individuals and are influenced by daily physical conditions, making it difficult for users to achieve their fitness goals.

Innovation Solution

An electronic device and method that receive heart rate data, calculate heart rate variation, and analyze it to determine threshold values for fat burning, allowing for personalized exercise intensity recommendations based on the correlation between heart rate and heart rate variation data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If heart rate monitoring is used to estimate fat burning, then exercise intensity can be monitored, but the accuracy is insufficient because fat burning varies greatly among individuals and daily conditions

Engineering Contradiction:

Improvefat burning estimation accuracyVSAvoidindividual variation in fat burning characteristics

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent changes from using only heart rate as a parameter to using heart rate variation (HRV) parameters in addition to heart rate. HRV provides additional physiological information that varies with individual characteristics and daily conditions, enabling more accurate and adaptive fat burning estimation that accounts for personal differences in fat burning characteristics.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If fixed intensity levels are recommended for exercise, then users can follow simple guidelines, but these do not account for daily physical condition variations

Engineering Contradiction:

Improveexercise guidance simplicityVSAvoidoptimal intensity determination

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback by continuously monitoring both heart rate and heart rate variation during exercise, then using this real-time data to dynamically determine and adjust fat burning threshold values. This feedback mechanism allows the system to adapt to daily physical condition variations while providing reliable, personalized exercise intensity recommendations.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent performs preliminary determination of fat burning threshold values by analyzing heart rate and heart rate variation data before and during exercise sessions. This preliminary analysis establishes personalized baseline values that account for individual characteristics, which then guide exercise intensity recommendations.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If general population averages are used for fat burning estimation, then simple guidelines can be provided, but personal fitness levels and characteristics are not considered

Engineering Contradiction:

Improvepersonalization of exercise recommendationsVSAvoidanalysis methodology complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables self-service by using the user's own physiological data (heart rate and heart rate variation) to determine their personal fat burning threshold values. The system automatically analyzes the user's unique physiological responses during exercise and generates personalized recommendations without requiring external calibration or complex manual setup, making personalization accessible despite the sophisticated analysis methodology.

Inventive Principle:

Principle #25Self-service
