Signal Filtering Device for Automatic Ring Mode Switching

Solution Overview

Problem

Traditional methods for switching mobile devices to silent mode in disturbance-prone areas are inefficient, as they require manual intervention by the user and do not account for incoming calls received before entering the area.

Innovation Solution

A method and device that intercept signals entering a predetermined area, adding a specific ring mode and authentication information to automatically change the ring mode of mobile devices within that area, using an interception mechanism and signal filtering device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual setting change is required to switch ring mode, then the mobile terminal can be controlled to switch ring mode, but the ease of operation deteriorates due to manual intervention requirement

Engineering Contradiction:

Improvering mode switching controlVSAvoidmanual setting change

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The mobile terminal automatically switches to silent ring mode when entering a predetermined area without requiring manual user intervention. The system uses location information and signal interception to autonomously change the ring mode, making the terminal serve itself rather than requiring user configuration.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-configures the silent ring mode setting before the user enters the predetermined area. When the terminal detects it is entering the area (through location information or signal interception), the predetermined silent ring mode is automatically applied in advance, eliminating the need for manual setting changes at the moment of entry.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If good manner signal broadcasting is used to switch ring mode, then the ring mode can be changed in predetermined area, but the reliability deteriorates because calls received before entering the area are not affected

Engineering Contradiction:

Improvering mode switchingVSAvoidring mode change coverage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary action by intercepting calls before they enter the predetermined area and attaching the silent ring mode setting in advance. This ensures that even if a call is received before the user enters the area, the ring mode is already changed to silent, providing reliable coverage for all incoming calls regardless of when they were received.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If manual ring mode change is required, then the mobile device can be controlled, but the productivity deteriorates due to inconvenient manual intervention

Engineering Contradiction:

Improvering mode controlVSAvoidring mode switching efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The mobile terminal automatically switches to silent ring mode when entering a predetermined area without requiring manual user intervention. The system uses location information and signal interception to autonomously change the ring mode, making the terminal serve itself rather than requiring user configuration.

AI summary

A method for intercepting signals so as to change the ring mode of a mobile device includes the following steps. Initially, a signal about to enter a predetermined area is intercepted. Then, a specific ring mode is added to the signal according to contents of the signal. Next, the signal having the specific ring mode is sent to a mobile device located in the predetermined area. Subsequently, the mobile device uses the specific ring mode as the ring mode of the mobile device upon receipt of the signal. A device applying the method is also disclosed.
