Problem

Existing methods for assessing lower body strength and endurance, such as the Sit to Stand test, face challenges in automation and privacy preservation, particularly in home settings, where wearable sensors require compliance and calibration, and camera-based systems raise privacy concerns.

Innovation Solution

A system utilizing non-wearable, privacy-preserving sensors like mm-wave radar or LIDAR, which can automatically detect and measure sit to stand movements without calibration, providing a 3D point cloud analysis and trend monitoring for endurance testing, enabling self-administration and continuous assessment in home or clinical settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If camera-based systems are used for automated sit to stand testing, then automation capability is improved, but privacy concerns worsen

Engineering Contradiction:
Improveautomation capabilityVSAvoidprivacy concerns
Core Design Contradiction:
Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces camera-based optical systems with mm-wave radar sensing technology. The radar system uses electromagnetic waves to detect motion and posture changes during sit-to-stand exercises, achieving automated testing without the privacy intrusion of visual recording. This substitution maintains automation capability while eliminating the harmful privacy factor associated with camera surveillance.

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

2Measurement precision

If wearable sensors are used for sit to stand testing, then measurement precision is improved, but ease of operation worsens due to compliance and calibration requirements

Engineering Contradiction:
Improvemovement detection accuracyVSAvoidcompliance and calibration requirements
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The radar-based system automatically detects and tracks the user's body movements without requiring the user to wear any devices or perform calibration procedures. The system self-adjusts to detect sit-to-stand motions passively, eliminating the compliance burden on users while maintaining measurement precision through automated motion detection algorithms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the sensing function from the user's body (wearable sensors) and places it in the environment (radar system). This extraction removes the need for user compliance with wearable devices while preserving measurement capability through environmental sensing of body movements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If specialized equipment is used for endurance testing, then measurement precision is improved, but device complexity worsens

Engineering Contradiction:
Improveendurance test accuracyVSAvoidspecialized equipment requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The radar system serves multiple functions: it detects posture changes, counts repetitions, measures exercise duration, and provides feedback for various types of physical exercises beyond just sit-to-stand tests. This multi-functionality reduces the need for specialized equipment for different exercise types while maintaining measurement precision through a single versatile platform.

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