Solution Overview

Problem

Current radio communication equipment limitations restrict the use of non-OEM accessories, impairing functionality and preventing seamless integration with recording and wireless devices, especially in military and law enforcement scenarios where flexibility and weight reduction are crucial.

Innovation Solution

A radio interface apparatus with a pass-through portion and conversion portion that maintains electrical continuity between OEM and non-OEM accessories, enabling the use of non-traditional devices while preserving OEM functionality, and a method for sharing communication resources through a communal wireless module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the auxiliary port is used for non-OEM accessories, then connectivity with non-traditional devices is enabled, but the radio's native functionality (microphone, speaker, PTT) cannot be accessed by those accessories

Engineering Contradiction:
ImproveConnectivity with non-traditional devicesVSAvoidAccess to radio's native functionality
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adapter segments the auxiliary port's electrical contacts into multiple independent connection groups, each routed to different connectors. This allows non-OEM accessories to access specific radio functions (e.g., audio output to headphones, recording input to XLR) while other functions remain accessible through alternative paths, resolving the contradiction between expanded connectivity and functional accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter provides universal access to the radio's native functionality across multiple connector types. Each connector on the adapter is designed to provide specific radio functions (microphone, speaker, PTT, audio I/O) in formats compatible with different accessory types. This multi-functionality ensures that non-OEM accessories can access the radio's native capabilities while maintaining ease of operation through familiar connector interfaces.

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

2Weight of moving object

If a single radio is shared among multiple users, then equipment weight is reduced, but seamless access for each user requires complex resource sharing mechanisms

Engineering Contradiction:
ImproveTotal equipment weightVSAvoidResource sharing mechanism complexity
Core Design Contradiction:
Weight of moving objectVSDevice complexity

Solution Approach 1:

The adapter segments the radio's auxiliary port into multiple independent connection paths, allowing multiple users to connect their accessories simultaneously without requiring complex software-based resource sharing. Each user gets dedicated physical access to specific radio functions through separate connectors, simplifying the resource sharing mechanism while reducing total equipment weight through radio sharing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter enables self-service resource allocation for multiple users. Each user can independently connect their accessories to the appropriate connectors without requiring system administrator intervention or complex authentication protocols. The physical segmentation of connections provides automatic resource isolation, reducing the complexity of resource sharing mechanisms while enabling lightweight radio sharing among multiple users.

Inventive Principle:
Principle #25Self-service

AI summary

An apparatus for interconnecting a radio communication equipment connector with non-Original Equipment Manufacturer (OEM) accessories includes a pass through portion including a first connector and a second connector having the same type and an opposing gender with respect to the first connector. A conversion portion is coupled adjacent the pass through portion and is configured to electrically interface with one of the plurality of the contacts of the first connector or the second connector. The conversion portion is further configured to transmit a signal from one of the plurality of contacts of the first connector or the second connector to a non-OEM accessory. Additionally, the apparatus is configured to concurrently maintain the functionality between an OEM accessory and a radio connected thereto.
