Wireless Device Emergency Voice Transmission Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless devices with emergency call functions often rely on pre-recorded messages, which may not transmit the sender's latest information in emergency situations, especially when the sender is unable to speak.
Innovation Solution
A wireless device with an emergency call mode that automatically alternates between sending and receiving voice actions at fixed intervals, using a voice recorder to capture and send real-time voice inputs, allowing for continuous transmission of the sender's status without requiring constant user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If pre-recorded messages are used for emergency calls, then the device can transmit information when the sender is unable to speak, but the information transmitted is not the latest status of the sender
Solution Approach 1:
The system automatically records and transmits the sender's status without requiring continuous user input. The voice recorder captures speech automatically when detected, and the sending controller transmits recorded information when no new speech is detected, enabling the system to serve itself in monitoring and transmitting emergency status.
Solution Approach 2:
The system dynamically switches between real-time voice transmission and pre-recorded message transmission based on whether speech is currently being input. When speech is detected, it transmits real-time; when no speech is detected, it transmits recorded messages, creating a dynamic adaptation to the sender's current state.
2Loss of information
If real-time voice transmission is used during emergency calls, then the latest information is transmitted, but the user burden increases requiring constant speaking
Solution Approach 1:
The system automatically detects speech input and manages transmission without requiring the user to continuously speak or operate the device. The voice recorder and sending controller work autonomously to capture and transmit status information, reducing user burden while maintaining information freshness.
Solution Approach 2:
The system uses periodic checking of speech input to determine whether to transmit real-time voice or recorded messages. This periodic detection mechanism allows the system to maintain latest information transmission while reducing user burden by only requiring speech when status changes occur.
3Extent of automation
If automatic repetition of sending and receiving actions is implemented, then the device can operate without constant user activation, but the device complexity increases
Solution Approach 1:
The voice recorder and sending controller are integrated into a unified emergency call system that shares common resources and control logic. This merging reduces overall system complexity while maintaining automatic operation capabilities, as the components work together rather than as separate independent systems.
Solution Approach 2:
The voice recorder serves multiple functions: capturing real-time speech, storing pre-recorded messages, and providing information to the sending controller. This multi-functionality reduces the need for separate dedicated components, thereby reducing device complexity while maintaining high automation.

AI summary
A wireless device having an action mode that automatically repeats, at a fixed temporal interval, a sending action of sending a voice and a receiving action of receiving the voice includes a voice recorder configured to record the voice therein when the voice is input from a microphone during execution of the action mode, a sending controller configured to send the voice input in the sending action during the execution of the action mode, and a recording controller configured to control recording in the voice recorder, wherein the sending controller is further configured to send the voice recorded in the voice recorder when the voice is not input from the microphone in the sending action.
