Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If human observation and manual camera selection are used, then the system is simple to operate, but the response time is slow and accuracy is reduced

Engineering Contradiction:
Improveresponse timeVSAvoidsystem complexity
Core Design Contradiction:

Solution Approach 1:

The patent replaces manual human observation and camera selection with an automated computer vision system that uses image processing algorithms to detect player and ball positions and automatically selects optimal camera angles, eliminating the mechanical delay of human reaction time while maintaining system functionality

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary computer processing system that acts as a mediator between the cameras capturing the event and the broadcast output, automatically analyzing position data and making camera selection decisions to bridge the gap between raw visual data and optimized broadcast content

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If automated camera selection based on real-time position data is implemented, then the response speed and accuracy improve, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional integrated system where the computer processing unit performs multiple tasks including detecting player positions, tracking ball movement, determining optimal camera angles, and controlling camera selection, allowing a single system to handle all functions rather than requiring separate specialized devices for each task

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses self-service by automatically processing its own captured video data to determine positions and make camera selections without requiring external manual intervention, with the computer vision algorithms independently analyzing the video feeds and making autonomous decisions about which cameras to activate

Inventive Principle:
Principle #25Self-service

Solution Approach 1:

The patent implements feedback by continuously monitoring the positions of players and the ball from multiple camera feeds and using this real-time information to dynamically determine which camera provides the optimal view, creating a closed-loop system where coverage quality informs camera selection decisions

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent changes the parameter of camera selection from a static manual choice to a dynamic automated decision based on real-time position parameters, where the optimal camera is determined by algorithms analyzing spatial coordinates, player movements, and ball position rather than operator preference

Inventive Principle:
Principle #35Parameter changes

AI summary

Position information of equipment at an event, such as a ball, one or more players, or other items in a game or sporting event, is used in selecting camera, camera shot type, camera angle, audio signals, and/or other output data for providing a multimedia presentation of the event to a viewer. The position information is used to determine the desired viewer perspective. A network of feedback robotically controlled Pan-Tilt-Zoom (PTZ), manually controlled cameras and stationary cameras work together with interpolation techniques to create a 2D video signal. The position information may also be used to access gaming rules and assist officiating of the event. The position information may be obtained through a transceiver(s), accelerometer(s), transponder(s), and/or RADAR detectable element(s) fitted into the ball, apparel or equipment of players, the players themselves, or other playing equipment associated with the game or sporting event. Other positioning methods that can be used include infrared video-based tracking systems, SONAR positioning system(s), LIDAR positioning systems, and digital signal processing (DSP) image processing techniques such as triangulation.
