Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a land line or Voice-over-IP line is used for telephone conferencing, then echo cancellation and audio transmission are achieved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the land line or Voice-over-IP line connection from the traditional conferencing system, eliminating the need for these complex connections while maintaining echo cancellation functionality through the mobile phone's existing capabilities
Solution Approach 2:
The mobile phone is utilized for multiple functions including audio transmission, echo cancellation, and conferencing coordination, replacing the need for separate land line infrastructure and reducing overall system complexity
2Reliability
If a land line or Voice-over-IP line is used for telephone conferencing, then audio transmission is achieved, but flexibility and cost are reduced
Solution Approach 1:
The system dynamically utilizes the mobile phone's existing network capabilities and Bluetooth interface, allowing flexible adaptation to different mobile networks and configurations without being constrained by fixed land line infrastructure
Solution Approach 2:
The mobile phone acts as an intermediary device between participants, utilizing its existing network connectivity and Bluetooth interface to enable flexible conferencing without requiring direct land line connections
3Ease of operation
If Bluetooth technology is used for wireless audio communication, then flexibility and ease of operation are improved, but signal processing capability may be reduced
Solution Approach 1:
The mobile phone's Bluetooth interface and signal processing capabilities are utilized to handle audio transmission and echo cancellation independently, eliminating the need for additional external equipment and simplifying system operation
Data Source
AI summary
A telephone conferencing apparatus is disclosed. The apparatus utilizes Bluetooth or similar wireless data exchange technology to connect a mobile telephone to an audio conferencing system. The device transmits processed audio from local input sources over the Bluetooth-enabled mobile telephone utilizing the mobile phone network of the user's choice. Audio signals received into the device from mobile telephones are sent to the far end during a telephone conference call, and audio signals from the far-end on a mobile or wireless telephone call will route to the audio output on the local device.
