Radio Communication System Multiplexing via Master Sub-Radio Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radio communication systems in military or police operations restrict voice command transfer, leading to weakened tactical operations due to limited access to main radio sets, hindering smooth communication among team members.
Innovation Solution
A radio communication system enabling multiplex communication, where individual members can possess either a main radio set for long-range communication, a master radio set connected to the main, or a subsidiary radio set for short-range communication, with the ability for subsidiary radio sets to switch to 'slave master' mode when out of range, ensuring continuous communication and notification of coverage area changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only squad leader level or higher possess main radio sets, then command control is centralized, but voice command transfer is restricted and tactical operations are weakened
Solution Approach 1:
The radio system is segmented into multiple functional types (main radio sets for commanders, master radio sets for squad leaders, and subsidiary radio sets for team members). This segmentation allows each role to have appropriate communication capabilities, enabling squad leaders to directly transmit commands to team members without requiring the main radio set, thus improving ease of operation while maintaining centralized control through the hierarchical structure.
Solution Approach 2:
The master radio set serves multiple functions: it can receive commands from main radio sets and forward them to subsidiary radio sets, and it can also independently transmit voice commands directly to subsidiary radio sets. This multi-functionality resolves the contradiction by providing both centralized command control (through main radio connectivity) and direct voice command transfer (through independent transmission capability).
2Device complexity
If subsidiary radio sets operate only within master radio coverage area, then communication structure is simple, but communication is interrupted when moving beyond coverage area
Solution Approach 1:
The radio system implements dynamic role assignment where subsidiary radio sets can automatically or manually transition to become slave master radio sets when the master radio is out of range. This dynamic adaptability allows the communication structure to reconfigure itself based on coverage requirements, maintaining communication continuity while teams move through different areas without requiring a fixed complex infrastructure.
Solution Approach 2:
The system enables self-service through automatic detection of coverage area boundaries and automatic initiation of slave master radio set establishment when communication is lost. The radio sets autonomously reconfigure the communication network without requiring external intervention, maintaining reliability while keeping the operational structure simple for users.
3Adaptability or versatility
If multiple radio types are introduced, then communication flexibility is improved, but system complexity increases
Solution Approach 1:
The patent introduces a new dimension of communication by adding master radio sets that operate on a different functional level between main radio sets and subsidiary radio sets. This creates a three-tier hierarchical structure (main → master → subsidiary) that provides communication flexibility at multiple levels while maintaining clear role definitions that prevent system complexity from becoming unmanageable.
Solution Approach 2:
Each radio set type is designed with specific local qualities optimized for its role: main radio sets have long-range capability for commanders, master radio sets have intermediate range and dual functionality for squad leaders, and subsidiary radio sets have short-range capability for team members. This specialization allows communication flexibility for each role while keeping individual device complexity low.

AI summary
A radio system capable of multiplexing communication includes a main radio, a master radio, a sub-radio, and a connecting unit having a PTT switch built therein. The enforcement of tactical operations and maintaining a dominant position in terms of combat effectiveness can be achieved by performing swift and smooth communication using master and sub-radios.
