Optical Twisting Posture Aid for Torso-Upper Limb Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports training aids fail to address coordinated motions between the head, torso, and upper limbs, leading to suboptimal performance and increased risk of injury, as they primarily focus on correcting the line of sight without considering the entire body's coordination during sports activities.
Innovation Solution
A twisting posture training aid that uses optical and audio/vibration feedback to display and correct the interactive motions of various body parts, including a torso marker and upper limb marker, ensuring proper alignment and timing through an operation plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical projection devices are used to correct head orientation and line of sight, then the line of sight accuracy is improved, but the body coordination and torso-upper limb motion coordination remain unaddressed
Solution Approach 1:
The training aid is divided into multiple independent functional modules: a head-worn optical projection device for line of sight correction, a torso-worn sensor for twisting motion detection, and an upper limb-worn sensor for arm motion detection. Each module independently monitors specific body parts, allowing comprehensive body coordination training while maintaining focused line of sight correction capability.
Solution Approach 2:
The patent combines previously separate training functions (line of sight correction, torso motion monitoring, upper limb motion monitoring) into a single integrated training system. The control unit processes data from all sensors simultaneously and provides unified real-time feedback, merging multiple correction functions into one versatile device that addresses both line of sight accuracy and body coordination.
2Manufacturing precision
If focus is placed on head orientation correction only, then the striking precision is improved, but the force application and overall performance remain limited
Solution Approach 1:
The system implements real-time feedback by continuously monitoring head orientation, torso twisting angle, and upper limb position through sensors, comparing these measurements against optimal motion patterns, and providing immediate corrective guidance through the optical projection device. This closed-loop feedback ensures both striking precision and optimal force application through coordinated body movements.
Solution Approach 2:
The training aid provides preliminary guidance on proper torso twisting and upper limb positioning before the actual striking action occurs. By pre-establishing correct motion patterns through optical projections and sensor feedback during the preparation phase, the system ensures that both precision and power are optimized before the ball is struck.
3Ease of operation
If improper postures are performed without trainer guidance, then the training accessibility is improved, but the risk of sports injuries increases
Solution Approach 1:
The training system enables self-service training by equipping users with wearable sensors and an optical projection device that automatically monitor and correct their own postures without requiring a human trainer. The system independently detects improper twisting motions, head orientations, and upper limb positions, providing real-time corrective feedback that allows users to train safely and correctly on their own.
