Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mobile communication systems fail to reliably distinguish urgent messages from non-urgent ones, leading to missed alerts and potential misuse of emergency notification features, and often require complex procedures or specialized applications to set up.

Innovation Solution

A mobile communication apparatus that automatically selects and plays a distinct alert ringtone for urgent messages based on geographical location and sender authorization, ensuring minimal environmental disturbance and easy sender classification without requiring special features or applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a normal ringtone is used for message notification, then the addressee is not disturbed during normal activities, but urgent messages may be missed

Engineering Contradiction:

Improveurgent message notification reliabilityVSAvoidenvironmental disturbance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system applies different notification qualities to different message types: normal messages use standard ringtones for minimal disturbance, while urgent messages trigger distinctive alert patterns with higher volume and repeated sequences, ensuring reliable notification only when necessary

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The notification system changes multiple parameters simultaneously for urgent messages: volume level increases, ringtone pattern changes to repeated sequences, and duration extends beyond normal notifications, creating a clearly distinguishable alert that ensures urgent messages are noticed

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the SOS function is activated to send urgent messages, then help can be requested, but the procedure is complex and time-consuming to set up

Engineering Contradiction:

Improveurgent message deliveryVSAvoidactivation procedure simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects urgent keywords in the message content and triggers the alert notification without requiring the user to manually activate any function or configure settings, making the urgent message feature as easy to use as sending a normal message

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-configures multiple urgent keywords and alert patterns in advance, so when an urgent message is needed, the user simply sends the message with a keyword and the system automatically executes the appropriate alert sequence without requiring any setup or configuration at the moment of need

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If proprietary ringtones are sent by organizations and operators, then communication can be customized, but the alert ringtone may be mistaken for other ringtones

Engineering Contradiction:

Improveringtone customizationVSAvoidurgent message recognition accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The urgent message alert uses an asymmetric notification pattern that differs fundamentally from normal ringtones: it employs repeated sequences with specific intervals, higher volume levels, and distinctive temporal patterns that cannot be confused with proprietary ringtones sent by operators or organizations

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The notification system segments ringtones into distinct categories: normal messages use standard or proprietary ringtones, while urgent messages trigger a completely separate alert pattern with different acoustic characteristics, ensuring clear differentiation and preventing misidentification

Inventive Principle:

Principle #1Segmentation

4Reliability

If the addressee mutes the phone to avoid disturbance, then normal notifications are suppressed, but urgent messages may still be missed

Engineering Contradiction:

Improveurgent message alert reliabilityVSAvoidenvironmental disturbance

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system anticipates the muting state and prepares a notification that can overcome it: when an urgent message is detected, the system triggers an alert pattern with sufficiently high volume and distinctive characteristics that can penetrate through the muted state, while still respecting the user's preference for minimal disturbance during normal operation

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

The invention relates to a mobile communication apparatus (100) and a method for receiving messages upon the arrival of a message flagged as "urgent", for automatically sounding an alert ringtone discernible from those assigned for other purposes, including those that various people may send and ring in the receiving mobile communication apparatus (100) of the addressee. When changes occur in the ringtones due to the displacement of the mobile communication apparatus (100) from one service area to another, by added new ringtones, the verification of the adequacy, if necessary, the updating of the alert ringtone is facilitated by a priori knowledge of the telecommunications networks with which the mobile communication apparatus (100) is authorized to affiliate, obtainable from the data of the user identification modules such as SIM, USIM, R-UIM, or the like, while ensuring a high probability to be heard, the alert ringtone may emit a few short rings and minimizing the disturbance by activation.
