Rescue Vehicle Interface Router for Multi-Party Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems in rescue vehicles lack flexibility, as they typically operate on a one-to-one basis, preventing simultaneous communication between multiple transmitters and receivers, and do not allow for broadcasting signals to multiple recipients or managing complete audio communication effectively.
Innovation Solution
A communication system with a flexible interface router that connects multiple speech input channels to multiple speech output channels, enabling simultaneous communication between multiple transmitters and receivers, and allowing for broadcasting signals, regardless of signal transmission modes or compatibility, using a programmable integrated circuit connected to an internal bus system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a one-to-one communication channel is used between transmitter and receiver, then the communication connection is simple and reliable, but the flexibility to address multiple receivers or enable simultaneous communication between multiple participants is lost
Solution Approach 1:
The interface router is designed as a universal communication device that can handle multiple communication modes simultaneously: one-to-one, one-to-many, and many-to-many communications. It provides a unified interface that adapts to different communication requirements without needing separate dedicated systems for each mode, thereby achieving multi-functionality in a single device.
Solution Approach 2:
The interface router acts as an intermediary between transmitters and receivers, managing all communication routing centrally. Instead of direct peer-to-peer connections, all communication flows through the router which intelligently directs signals to appropriate receivers based on the selected communication mode, enabling flexible addressing while maintaining system simplicity.
2Adaptability or versatility
If multiple transmitters and receivers are connected simultaneously, then communication flexibility is improved, but managing complete audio communication and signal routing becomes complex
Solution Approach 1:
The interface router incorporates feedback mechanisms that monitor the communication state and automatically adjust signal routing. When multiple transmitters and receivers are active, the router receives feedback about which participants should communicate, and dynamically configures the audio paths without requiring manual intervention, thereby simplifying operation while maintaining simultaneous communication capability.
Solution Approach 2:
The communication system is designed to be dynamic, allowing the router to reconfigure audio paths in real-time based on operational needs. The system can switch between different communication modes (one-to-one, one-to-many, many-to-many) dynamically during rescue operations, adapting to changing situations without requiring system reconfiguration or interrupting ongoing communications.
3Productivity
If broadcast signals are transmitted to multiple receivers, then information dissemination is improved, but the ability to manage selective communication becomes difficult
Solution Approach 1:
The interface router segments the audio communication system into independently controllable channels, where each receiver can be selectively addressed or grouped. This segmentation allows the system to transmit broadcast signals to multiple receivers simultaneously while also enabling selective communication with individual receivers or specific groups, as the router can independently manage each audio path without interference.
