Hall Effect Sensor Strut for Basketball Shooting Form Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basketball training aids lack real-time feedback throughout the entire shooting process, are not durable enough for repeated use, and fail to account for the 'flying elbow' issue in providing accurate shooting form feedback.
Innovation Solution
A basketball training apparatus with a strut assembly, Hall Effect sensor, magnets, controller, and alert mechanism that provides real-time feedback by securing to the user's upper and forearm, using pivotal movement to detect optimal angles and generate notifications through vibration, audio, and visual alerts, ensuring proper shooting form from start to follow-through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing basketball training aids are used, then they provide some feedback on shooting form, but they lack real-time feedback throughout the entire shooting process
Solution Approach 1:
The training aid is divided into multiple independent sensor modules (accelerometer, gyroscope, magnetometer, Hall effect sensor) that monitor different aspects of shooting form independently. Each sensor provides specific measurements that are then integrated to give comprehensive real-time feedback throughout the entire shooting process, from ball release through follow-through.
2Reliability
If existing basketball training aids are used, then they provide feedback mechanisms, but they lack durability due to sleeves soaking sweat and ripping
Solution Approach 1:
The training aid utilizes a flexible band made of durable, sweat-resistant material that can withstand repeated use and exposure to moisture. The band is designed to be stretched over the user's forearm and secured without soaking or ripping, providing a reliable mounting surface for the sensor components while maintaining durability in sweaty training conditions.
3Measurement precision
If existing basketball training aids are used, then they attach to the arm, but they do not account for the flying elbow in providing accurate feedback
Solution Approach 1:
The training aid incorporates multiple sensor types (accelerometer, gyroscope, magnetometer, Hall effect sensor) that can detect and differentiate between various shooting movements including proper form and flying elbow variations. The system is designed to adapt to different shooting styles and identify deviations from proper form, providing accurate feedback regardless of the specific shooting variation being performed.
4Measurement precision
If a complex sensor system is implemented for real-time feedback, then measurement precision improves, but device complexity increases
Solution Approach 1:
Multiple sensor components (accelerometer, gyroscope, magnetometer, Hall effect sensor) are integrated into a single compact training aid device that attaches to the forearm. The sensors are combined on a common platform with shared power and data processing, reducing overall device complexity while maintaining high measurement precision for detecting shooting form parameters.

AI summary
A basketball training apparatus to provide user feedback on shooting form is provided. The basketball training apparatus includes a strut assembly coupled to a user's upper arm and forearm, the strut assembly having an upper strut pivotably mounted to a lower strut, a Hall Effect sensor disposed within the junction of the upper and lower struts, a pair of magnets coupled to the strut assembly's junction, a controller disposed within the strut assembly and electrically coupled to the Hall Effect sensor, and an alert mechanism disposed within the strut assembly and electrically coupled to the controller. Pivotable movement of the upper strut relative to the lower strut to either a first optimal angle or second optimal angle enables the alert mechanism to generate a notification.
