Solution Overview

Problem

Radio frequency channel coordination is complex and prone to interference issues, especially during large events, due to various variables involved, leading to potential conflicts and misuse, which existing technologies struggle to manage effectively.

Innovation Solution

A system that automatically reserves radio frequency channels using customized, modulated carriers to prevent unauthorized use, employing a Controller that accesses a Channel Database to manage channel allocation and interference considerations, ensuring channels are protected until authorized users initiate transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual frequency coordination procedures are used, then flexibility in channel allocation is maintained, but interference control and coordination reliability deteriorate due to human errors and intentional misuse

Engineering Contradiction:

Improvecoordination reliabilityVSAvoidcoordination system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system enables automatic frequency coordination where the coordination system itself performs channel allocation and interference detection without human intervention. The automated frequency coordinator autonomously manages channel assignments, detects interference conditions, and reallocates frequencies based on detected interference, making the system self-regulating and eliminating human error while maintaining coordination reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors the radio frequency environment for interference and uses this feedback to dynamically adjust channel allocations. The automated frequency coordinator detects interference signals and automatically reallocates affected channels to different frequencies, creating a closed-loop control system that maintains coordination reliability through real-time feedback and automatic correction.

Inventive Principle:

Principle #23Feedback

2Productivity

If automated channel allocation is implemented, then coordination efficiency and interference control improve, but system complexity and initial setup requirements worsen

Engineering Contradiction:

Improvecoordination efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system replaces manual mechanical coordination procedures with automated electronic frequency detection and allocation. The automated frequency coordinator uses electronic signal processing to detect interference and automatically performs channel reallocation, substituting human-operated mechanical systems with automated electronic control to improve coordination efficiency while managing system complexity through software-based solutions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The automated frequency coordinator performs multiple functions including interference detection, channel allocation, frequency monitoring, and dynamic reallocation within a single integrated system. This multi-functional approach improves coordination efficiency by consolidating multiple coordination tasks into one automated device, thereby managing overall system complexity through functional integration rather than proliferation of separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If channels are left unreserved, then channel availability and ease of access improve, but interference from unauthorized users and co-channel interference worsen

Engineering Contradiction:

Improvechannel access easeVSAvoidinterference level

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary channel reservation by automatically allocating and reserving frequency channels before they are needed for transmission. The automated frequency coordinator pre-assigns channels to potential users and maintains a reservation status, ensuring that when transmission is required, the channel is already reserved and protected from unauthorized use, thus preventing interference while maintaining ease of access through automated management.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The automated frequency coordinator acts as an intermediary between channel resources and users, managing channel reservations and interference protection automatically. It mediates between the need for channel availability and the need to prevent unauthorized access by maintaining a centralized reservation system that automatically grants or denies channel access based on current allocations and interference conditions, thereby protecting against interference while preserving ease of legitimate access.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An apparatus and method are provided for intermittent communication over at least one of a plurality of channels. The method includes receiving by the apparatus a reservation request from a user, detecting an available channel, generating a reservation signal on the available channel, receiving an activation request, and handing said available channel over to the user.
