Solution Overview

Problem

Existing dieting programs face challenges in reliably measuring fat loss, leading to reduced motivation due to daily weight fluctuations caused by factors other than fat loss, such as water balance, making it difficult for individuals to consistently follow their weight loss regimen.

Innovation Solution

A system and method that utilize a breath analyzer to measure acetone levels in a user's breath, determining a ketosis score which serves as an indicator of fat metabolism, and provides dietary and lifestyle recommendations to guide the user's diet, using a smartphone application to connect with the breath analyzer and display the ketosis score, allowing for personalized feedback and motivation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If total body weight is used to measure fat loss progress, then weight loss can be tracked, but measurement reliability deteriorates due to body fluid balance fluctuations and other factors

Engineering Contradiction:
Improvefat loss measurement reliabilityVSAvoidweight loss tracking accuracy
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent extracts the specific indicator of fat metabolism (breath acetone) from the general weight measurement approach. By measuring acetone concentration in breath samples, the system isolates a direct marker of ketosis and fat burning, eliminating the confounding effects of water balance and other factors that affect total body weight measurements.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces breath acetone concentration as an intermediary indicator between dietary intake and fat loss progress. Instead of directly measuring fat mass changes, the system uses acetone levels in breath as a mediator that reflects the rate of fat metabolism, providing a more reliable and responsive measure of diet effectiveness.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If simple weight monitoring is used to track diet progress, then ease of operation is maintained, but user motivation deteriorates due to unreliable fat loss indicators

Engineering Contradiction:
Improvediet tracking simplicityVSAvoidfat loss indication accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the simple mechanical act of weighing oneself with a chemical sensing approach. Instead of using a scale to measure body weight, the system uses a breath analyzer with chemical sensors (such as metal oxide semiconductor sensors or infrared sensors) to detect acetone concentration in breath, substituting mechanical measurement with chemical analysis.

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

3Measurement precision

If breath acetone measurement is implemented to monitor ketosis, then fat loss measurement reliability is improved, but device complexity increases

Engineering Contradiction:
Improveketosis level accuracyVSAvoidbreath analyzer system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the measurement parameter from macroscopic body weight to molecular-level acetone concentration. By detecting the presence and concentration of acetone molecules in breath using chemical sensors, the system achieves precise ketosis monitoring. This parameter change enables reliable fat metabolism measurement while allowing for portable device design through the use of compact sensor technologies.
