Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-mode communication systems for hearing and speech impaired users lack efficient mode synchronization and connection verification, often requiring a call set-up time and assuming correct device adjustments without verification.
Innovation Solution
A method and system for initiating communication in a multi-mode system that includes transmitting a signal indicative of the preferred mode via a two-way radio frequency communication system, receiving notification of signal receipt, and adapting the system to ensure communication in the preferred mode, utilizing a modem and TTY interface module processor for automated mode synchronization and connection verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a call set-up time is used to allow device adaptation, then communication reliability is improved, but communication time is increased
Solution Approach 1:
The system performs preliminary actions by automatically exchanging mode indication signals and connection verification signals before actual communication begins. The call initiator transmits a mode indication signal to indicate the preferred communication mode, and the call recipient responds with a connection verification signal, ensuring both devices are properly adapted before data transmission starts, thereby eliminating the need for a separate call set-up time while maintaining reliability
Solution Approach 2:
The system implements feedback mechanisms where the call recipient sends back mode indication signals and connection verification signals to confirm proper adaptation. This feedback loop ensures that both devices are synchronized in the preferred communication mode before actual communication begins, resolving the contradiction by making the adaptation process implicit and instantaneous rather than requiring a separate time period
2Productivity
If automated mode synchronization is implemented, then communication efficiency is improved, but device complexity is increased
Solution Approach 1:
The system performs self-service by automatically exchanging mode indication signals and connection verification signals without requiring manual intervention. The call initiator and call recipient autonomously synchronize their communication modes through automated signal exchange, improving efficiency while the complexity is managed through standardized protocol implementation rather than complex user-side processing
3Reliability
If connection verification is added to ensure proper mode adaptation, then communication reliability is improved, but signal transmission time is increased
Solution Approach 1:
The system merges the mode indication signal transmission and connection verification into a single integrated exchange process. The mode indication signal and connection verification signal are transmitted in sequence during the same call setup phase, combining what could be separate time-consuming operations into a unified process that ensures reliability without proportionally increasing total transmission time
