Sound Signal Transfer Device for Cross-System Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems where a mobile station with two-way communication capabilities interacts with a business wireless system supporting one-way communication, users of the mobile station often interrupt the business wireless system while transmitting, leading to incomplete sound signal reception due to the inability to hear the mobile station's sound during transmission.
Innovation Solution
A transfer device with reception and transmission units that buffer sound signals from the mobile communication system while the business wireless system is transmitting, then synchronizes and adjusts speech speed to ensure complete signal transfer, and includes a detection unit to notify the business wireless system of incoming signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the business wireless system uses one-way communication to ensure reliable transmission, then transmission reliability is improved, but the user cannot receive sound signals during transmission, causing communication completeness to deteriorate
Solution Approach 1:
The transfer device buffers incoming sound signals from the mobile communication system in advance, before the business wireless transmission completes. This preliminary buffering ensures that when transmission finishes, the received sound is already available for immediate playback, preventing any information loss while maintaining the reliability of the one-way communication system.
Solution Approach 2:
The transfer device acts as an intermediary between the mobile communication system and the business wireless system. It receives sounds from the mobile system, buffers them, and transmits them to the business wireless terminal, mediating the communication gap and ensuring complete sound signal transfer without compromising either system's operational characteristics.
2Loss of information
If the transfer device buffers sound signals to ensure complete transfer, then communication completeness is improved, but transmission delay increases, causing productivity to deteriorate
Solution Approach 1:
The buffering operation is performed in advance during the transmission period, not after. This allows the sound signal to be prepared and ready for immediate transmission once the business wireless channel becomes available, minimizing actual delay while ensuring complete transfer.
Solution Approach 2:
The transfer device continuously buffers incoming sound signals without interruption during the transmission process. This continuous buffering ensures that no part of the sound signal is lost, while the system maintains optimal efficiency by being ready to transmit immediately when the channel becomes available.
3Reliability
If the system adjusts speech speed to synchronize transmission timing, then communication coordination is improved, but device complexity increases, causing ease of operation to deteriorate
Solution Approach 1:
The transfer device changes the speech speed parameter of buffered sound signals to match the transmission timing requirements. By adjusting this single parameter, the system achieves precise synchronization between the end of business wireless transmission and the completion of sound signal transfer, ensuring reliable coordination without requiring complex mechanical or structural modifications.

AI summary
A first reception unit receives a sound signal destined to a second terminal device in a second communication system supporting one way communication from a first terminal device in a first communication system supporting two way communication. A first transmission unit transmits the sound signal received in the first reception unit to the second terminal device. A second reception unit receives a sound signal destined to the first terminal device from the second terminal device. A second transmission unit transmits the sound signal received in the second reception unit to the first terminal device. A storage unit stores the sound signal received in the first reception unit if the second transmission unit is transmitting the sound signal received in the second reception unit. The first transmission unit transmits the sound signal stored in the storage unit when reception of the sound signal in the second reception unit is completed.
