Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the system uses a fixed ideal position for posture monitoring, then it can accurately detect deviations from that position, but it cannot adapt to different exercises and individual user preferences

Engineering Contradiction:
Improveadaptability to different exercises and user preferencesVSAvoidaccuracy of posture deviation detection
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system implements dynamic recalibration that allows the ideal position to be adjusted based on different exercises and individual user preferences. The calibration data structure stores exercise-specific ideal positions, enabling the system to adapt from static to dynamic monitoring requirements across various activities

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the reference position parameter dynamically based on the selected exercise type and user preferences. By storing multiple ideal positions for different exercises (squat, lunge, press up, plank, bridge) and allowing user-specific calibration, the system maintains measurement precision for each specific context while achieving overall versatility

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the system is designed for specific exercises only, then it can provide accurate monitoring for those exercises, but it cannot be used for various types of exercises without changes

Engineering Contradiction:
Improveversatility across exercise typesVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is designed with universal applicability across multiple exercise types (squat, lunge, press up, plank, bridge) by implementing a calibration framework that stores exercise-specific ideal positions. The same hardware and processing unit handle all exercise types, achieving multi-functionality without requiring separate systems for each exercise

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

Solution Approach 2:

The system performs preliminary calibration for each exercise type to establish the ideal position before actual monitoring begins. By pre-storing calibration data for different exercises and allowing user-specific calibration, the system prepares the reference framework in advance, enabling seamless transition between exercise types without complex real-time reconfiguration

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the system enforces a single ideal position, then it can provide clear feedback for that position, but it prevents users from actively maintaining different postures

Engineering Contradiction:
Improveuser autonomy in posture selectionVSAvoidaccuracy of posture feedback
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system transitions from enforcing a single static ideal position to dynamically adapting to user-selected ideal positions. Users can actively choose and recalibrate their preferred posture for each exercise type, and the system reliably provides feedback relative to that user-defined reference, maintaining both autonomy and reliability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback relative to the user-defined ideal position rather than a predetermined standard. By allowing users to set their preferred posture and then monitoring deviations from that personalized reference, the system maintains measurement reliability while enabling user autonomy in posture selection

Inventive Principle:
Principle #23Feedback

AI summary

The present application discloses a novel spinal posture monitoring system designed to enhance user awareness and encourage proper posture habits; wherein the system may utilize two Arduino flex sensors strategically positioned back-to-back along the user's spine, accurately capturing and mimicking the natural movements of the spine in both flexion and extension movements. The acquired data may be transmitted in real-time to a dedicated mobile application allowing the user to correct the poor posture habits promptly. The mobile application may facilitate recalibration of sensor data based on the desired back position of the wearer.
