Voice Command Seeking System for Silent Mode Device Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in locating misplaced mobile electronic devices, especially when they are in silent mode, as calling the device does not produce a ringtone.
Innovation Solution
A seeking system within the mobile device that activates a predetermined ringtone upon receiving a specific voice command, allowing users to locate their device even in silent mode by comparing user-input voice commands with pre-recorded standards and activating the ringing circuit if the command meets the identification criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile device is set to silent mode to prevent disturbances, then noise pollution is reduced and sleep is protected, but the ability to locate the device through ringtone becomes unavailable
Solution Approach 1:
The system performs preliminary action by pre-recording standard voice commands and storing them in memory before the actual location search is needed. When the user needs to locate the device, the system compares the spoken command against these pre-stored standards, enabling the silent mode location feature to function without requiring the device to be in a non-silent state beforehand.
Solution Approach 2:
The patent introduces an intermediary mechanism - a voice command recognition system that acts as a mediator between the user and the device location function. This intermediary allows the user to trigger the ringtone playback through voice commands even when the device is in silent mode, thus resolving the contradiction between noise reduction and location capability.
2Speed
If the seeking system is always active to enable immediate location capability, then device location speed is improved, but power consumption increases
Solution Approach 1:
The system implements periodic action by activating the voice command recognition and ringtone playback functions only when needed - specifically when a missed call is detected and the user needs to locate the device. The seeking system remains dormant during normal operation, consuming minimal power, and is activated periodically only when the location function is actually required.
Solution Approach 2:
The system performs self-service by automatically detecting when location assistance is needed through the missed call detection mechanism. When a call is missed, the system autonomously activates the voice command recognition and ringtone playback functions without requiring continuous user input or system activation, thus optimizing power consumption while maintaining rapid response capability when needed.

AI summary
A mobile electronic device stores a standard voice command and a voice command identification standard. When an incoming call is regarded as a missed call and a voice command is detected, the mobile electronic device compares characteristics of the voice command with characteristics of the standard voice command, so as to determine if the voice command satisfies the voice command identification standard. The mobile electronic device further activates a ringing circuit to play a predetermined ring tone in response that the voice command satisfies the voice command identification standard, so as to help a user locate the mobile electronic device even if the mobile electronic device is in a silent mode.
