Basketball Shot Sensing via Embedded Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for improving shooting skills in basketball lack sufficient feedback, making it tedious and inefficient for players to develop a proper shooting stroke and touch.
Innovation Solution
A basketball sensing system that includes sensors within the ball to track various attributes of a shot, such as acceleration, spin, and launch parameters, transmitting data to a portable device for real-time analysis and feedback, allowing players to compare their performance with personal goals or other players.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional practice methods are used for developing shooting skills, then players can improve through repetition, but the process becomes tedious and lacks sufficient feedback
Solution Approach 1:
The patent implements a feedback mechanism by equipping the basketball with sensors that detect shot attributes (launch angle, spin rate, velocity) and provide real-time feedback to players through a mobile device. This allows players to immediately see whether their shot was good or bad and why, enabling rapid adjustment and improvement without tedious repetition
2Measurement precision
If sensors are added to the basketball to track shot attributes, then detailed feedback on shooting technique is provided, but the device complexity increases
Solution Approach 1:
The basketball serves multiple functions: it is both a playable sports equipment and a sensing device. The sensors integrated into the ball detect various shot attributes (launch angle, spin rate, velocity, release position) using a single multi-functional system, avoiding the need for separate detection devices and reducing overall system complexity
Solution Approach 2:
A mobile computing device acts as an intermediary between the sensors in the basketball and the player. The sensors collect data and transmit it to the mobile device, which then processes the information and presents it to the player in an understandable format, simplifying the interface between the complex sensing system and the user
Data Source
AI summary
An apparatus including a data acquisition device, a processing unit, a memory and an output device. The data acquisition device obtains at least one attribute of a shot of a basketball towards a basket. The at least one attribute is sensed by at least one sensor carried by the basketball or derived from signal output by the at least one sensor. The memory contains instructions to direct the processing unit to determine whether the shot is a made basket shot or a missed basketball shot by comparing the at least one attribute of the shot to one or more predetermined signature characteristics of a made basket. The output device presents output to a person based on the determination of whether the shot is a made basket shot or a missed basket shot.
