Solution Overview

Problem

Existing down and distance marker systems in American football lack real-time accuracy, safety, and communication, with existing line-to-gain indicators posing hazards to players and failing to provide visual indicators for first downs, and lacking integration with stadium displays.

Innovation Solution

An electronic down and distance marker system featuring light projectors for visual line-to-gain indicators, cameras for field perspective video recording, and remote control units for convenient operation, along with wireless connectivity for real-time data communication to stadium displays, enhancing safety by not altering the playing surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If plastic or vinyl sheets are placed on the ground as line-to-gain indicators, then visual indication of the line to gain is provided, but player safety deteriorates due to slipping hazards

Engineering Contradiction:
Improvevisual indicationVSAvoidslipping hazard
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical system of plastic/vinyl sheets placed on the ground with an optical system using light projectors that project the line-to-gain indicator onto the field surface. This substitution eliminates the need for physical markers that create slipping hazards while maintaining visual indication functionality.

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

Solution Approach 2:

Instead of placing physical markers on the field, the system creates an optical copy or projection of the line-to-gain indicator on the field surface. The projected light pattern replicates the visual information previously provided by physical sheets without the associated safety risks.

Inventive Principle:
Principle #26Copying

2Loss of information

If existing down and distance marker systems are used, then basic down and distance information is displayed, but real-time communication with stadium displays and officials is lacking

Engineering Contradiction:
Improveinformation communicationVSAvoidsystem integration
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The down and distance marker system is enhanced with multi-functionality by integrating wireless communication capabilities that enable real-time data transmission to multiple receivers including stadium displays, officials' devices, and television broadcast systems. This allows a single system to serve multiple communication functions simultaneously.

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

Solution Approach 2:

The system incorporates real-time feedback mechanisms where the marker system continuously transmits down and distance information to various stakeholders. The feedback loop ensures all parties receive updated information simultaneously, allowing for immediate response and decision-making based on current game state.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If visual indicators for first downs are added when it is hard to visually determine, then accuracy of first down determination is improved, but the system complexity increases

Engineering Contradiction:
Improvefirst down determination accuracyVSAvoidvisual indicator system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses distinct color changes and optical patterns projected on the field to clearly indicate first down lines. By utilizing different colors and visual patterns, the system enhances the visibility and precision of first down determination without requiring complex mechanical or electronic indicator mechanisms.

Inventive Principle:
Principle #32Color changes

AI summary

An electronic down and distance marker system that may comprise a first marker, a second marker connected to a first marker by a physical member having a distance of about ten yards, and a down marker. The present system may include a measurement device for measuring a linear distance between the down marker and the second marker and one or more electronic displays disposed on one of the down marker and the second marker that may display a down and/or the measured linear distance between the down marker and the second marker. A light projector may project one or more of a line of light corresponding to the line to gain, and/or a shape to optically mark the line to gain on the sideline. A remote control, camera and/or an improved wireless measurement and communications capability may also be incorporated into the present system.
