Ball Impact Detection Sensor Lines for Padel Court Corners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for determining whether a ball in padel hits the wall or the ground first, such as the 'Bola Huevo' situation, are often unclear and lead to disputes, especially in official matches, due to their complexity and reliance on intensive data processing or the need for sensors in the ball.
Innovation Solution
A device comprising at least two sensors and a processing unit, with sensor lines or strips placed strategically relative to the walls, allowing for indirect measurement of the ball's contact sequence with the walls, providing a simple and reliable method to determine if the ball first hits the ground or the wall in a 'Bola Huevo' situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex data processing or video images are used to determine ball contact sequence, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces sensor lines as intermediary elements positioned between the ball and the detection system. These sensor lines provide a simple binary detection (ball present or not) that mediates the complex task of determining contact sequence, eliminating the need for complex data processing while maintaining high measurement precision.
Solution Approach 2:
The patent replaces complex mechanical or computational detection systems with a simpler sensor-based system. Instead of using video images requiring intensive data processing, the invention uses sensor lines that provide direct, simple detection signals, substituting a complex mechanical/computational system with a simpler electronic sensing approach.
2Measurement precision
If sensors are placed in the ball to detect contact sequence, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Instead of placing sensors directly in the ball, the patent uses sensor lines as intermediary detection elements positioned in the environment. These external sensor lines detect the ball's presence and position, providing the same measurement function without the complexity of installing and calibrating sensors within the ball itself.
3Measurement precision
If sensor lines are placed close to walls to detect ball contact, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the detection system into multiple independent sensor lines positioned at different locations and heights. Each sensor line is a simple, independent unit that detects ball presence locally. This segmentation allows high measurement precision through multiple detection points while keeping each individual sensor unit simple and easy to install.
