Basketball Training Apparatus Using Hall Effect Sensors for Shooting Form Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basketball training aids lack real-time feedback on shooting form from the beginning to the follow-through and do not account for the 'flying elbow' issue, making it difficult for players to improve their shooting accuracy and consistency.
Innovation Solution
A basketball training apparatus that secures to the upper arm and forearm, using a strut assembly with Hall Effect sensors and magnets to provide real-time notifications through vibration, audio, and visual alerts when the user's arm and forearm are at optimal angles, ensuring proper shooting form from 90 degrees to 180 degrees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanical resistance tools are used to help achieve proper shooting form, then shooting form guidance is provided, but real-time feedback throughout the entire shot is lacking
Solution Approach 1:
The patent implements real-time feedback through sensors that continuously monitor arm position and provide immediate corrective information to the user during the entire shooting motion, eliminating the delay inherent in mechanical resistance tools that only provide passive guidance
Solution Approach 2:
The patent replaces mechanical resistance mechanisms with electronic sensing and feedback systems, substituting physical guidance structures with real-time digital monitoring and communication to provide more responsive and accurate form correction
2Measurement precision
If mechanical resistance tools are used to guide shooting form, then some form feedback is provided, but the flying elbow issue is not accounted for
Solution Approach 1:
The patent creates a comprehensive monitoring system that tracks multiple arm position parameters simultaneously, making the device adaptable to various shooting form issues including the flying elbow problem, rather than being limited to a single mechanical guidance function
3Loss of information
If coaches provide feedback during practice shots, then shooting form guidance is given, but instantaneous feedback during the course of a shot is difficult to provide
Solution Approach 1:
The system provides immediate automated feedback through sensors and communication devices that notify the user in real-time of form deviations, eliminating the time delay inherent in coach observation and verbal correction
Solution Approach 2:
The system enables the user to receive and process form correction information independently without requiring continuous coach intervention, allowing the user to self-correct during practice shots
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus provides immediate and comprehensive feedback on shooting form, enhancing the user's ability to maintain proper mechanics and improve shooting accuracy and consistency by alerting the player in real-time throughout the shot.
Implementation Method 1
a Hall Effect sensor disposed within the junction of the strut assembly

AI summary
A basketball training apparatus to provide user feedback on shooting form is provided. The basketball training apparatus includes a sleeve disposed around the user's upper arm and forearm, a strut assembly coupled to the sleeve and 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.
