Net Ball Indicator Using Impact-Triggered LED and Audio Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports, particularly Table Tennis, Tennis, Pickleball, and Volleyball, face uncertainty in determining whether a ball has hit the net, leading to inconsistent rulings and potential disputes.
Innovation Solution
A mechanism is integrated into the net that includes an impact line connected to a power source, triggering an LED light and audio signal upon ball impact, providing clear indication of a 'net ball' occurrence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If judges make rulings based on visual observation alone, then the judging process remains simple and quick, but accuracy and consistency in determining net ball hits deteriorates
Solution Approach 1:
The patent replaces the mechanical/visual observation system with an automated sensor-based system. Impact sensors embedded in the net automatically detect ball contacts and transmit signals to a processing system, eliminating reliance on judges' visual interpretation and providing objective, consistent detection results.
Solution Approach 2:
The patent introduces an intermediary system consisting of sensors, signal processing units, and communication modules between the net and the judging system. This intermediary automatically captures impact data and transmits it to authorities, who then make informed rulings without directly observing the play.
2Reliability
If the net apparatus is enhanced with detection mechanisms, then detection accuracy improves, but the cost and complexity of the equipment increases
Solution Approach 1:
The patent divides the net apparatus into modular functional segments: impact sensors integrated into the net structure, signal processing units, communication modules, and power sources. This segmentation allows each component to perform its specific function independently, improving reliability while keeping individual components simple and manageable.
Solution Approach 2:
The patent designs the detection mechanism to serve multiple functions: detecting net ball hits, tracking ball trajectory, measuring impact force, and providing real-time data transmission. This multi-functionality reduces the need for separate specialized equipment, thereby limiting the increase in overall system complexity.
3Measurement precision
If automated detection systems are implemented, then consistency and fairness improve, but the initial investment and maintenance costs increase
Solution Approach 1:
The patent implements self-service features where the detection system automatically monitors, records, and transmits data without requiring external intervention. The system self-calibrates, self-diagnoses, and maintains its own operational status, reducing the need for continuous human oversight and lowering long-term maintenance resource consumption.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors its own performance, compares detection results against established criteria, and automatically adjusts or alerts operators to potential issues. This closed-loop feedback ensures consistent and fair rulings while optimizing resource utilization by preventing errors before they occur.

AI summary
The Net Ball Indicator “NBI” was invented to enhance the sports of Table Tennis, Tennis, Pickle Ball or Volley Ball. This invention will indicate whether a net ball has occurred. There will no longer be the need for judges to make that call. Existing nets can be altered or new nets can be manufactured to know when a ball has hit it. If it is hit, then it will emit a sound and flash an LED light.
