Solution Overview

Problem

Conventional wearable devices for sensing sport postures lack adaptivity, requiring specific wearing positions and manners, and do not account for user differences in height, weight, age, gender, and health status, leading to inaccurate posture determination and high acquisition costs.

Innovation Solution

An adaptive sport posture sensing system and method that allows devices to be worn on arbitrary positions and in arbitrary manners, using multiple sensors and a processing unit to select appropriate reference data based on user body information and sport type, enabling accurate posture determination through a learning and determination mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional wearable devices use fixed wearing positions and manners, then device structure is simple, but adaptability to different users and scenarios deteriorates

Engineering Contradiction:
Improveadaptability to different wearing positions and usersVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wearable device is designed with universal functionality to operate correctly regardless of wearing position (wrist, ankle, knee, etc.) or wearing manner. The processing unit automatically adapts the sport posture determination algorithm based on detected wearing characteristics, enabling one device to serve multiple functions across different users and scenarios without requiring position-specific hardware variations.

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

Solution Approach 2:

The system dynamically changes processing parameters including reference data selection, sensitivity thresholds, and determination criteria based on detected wearing position and user characteristics (height, weight, age, gender, health status). This allows the same physical device to adapt its functional parameters to different wearing scenarios and user profiles, achieving versatility without structural complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If conventional wearable devices require specific wearing positions, then measurement precision is maintained, but ease of operation deteriorates

Engineering Contradiction:
Improveease of wearing the deviceVSAvoidsport posture determination accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The wearable device performs self-identification of wearing position and automatic adaptation of determination criteria without user intervention. The processing unit detects wearing characteristics and autonomously selects appropriate reference data and parameters, allowing users to simply wear the device anywhere on the body while the system handles the complexity of position-specific calibration and accuracy optimization.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple wearable devices are purchased for different wearing positions, then adaptability is improved, but acquisition cost increases

Engineering Contradiction:
Improvecoverage of different wearing positionsVSAvoidnumber of devices required
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single wearable device is designed to replace multiple position-specific devices through universal sport posture determination capability. The processing unit adapts the determination algorithm based on wearing position detection, enabling one device to perform the function of what would traditionally require multiple specialized devices, thereby reducing the quantity needed while maintaining comprehensive adaptability.

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

AI summary

An adaptive sport posture sensing system has a sensing device, a sensing signal acquiring unit and a sport posture processing unit. In the determination mode, the sport posture processing unit selects one piece among multiple established pieces of sport posture reference data according to a sport name, a wearing position and one piece of user body information, the sensing signal acquiring unit obtains at least one first sensing signal sensed by the sensing device, and the sport posture processing unit compares a sport posture data generated based upon the at least one first sensing signal with the selected piece of the sport posture reference data, so as to determine whether a sport posture of the user is correct or not.
