Solution Overview

Problem

Existing home network systems face challenges in detecting unauthorized intrusions without consuming excessive energy, leading to limited operating time and increased costs, while also raising privacy concerns due to the need for monitoring units like cameras.

Innovation Solution

A mobile terminal device equipped with an entry determining unit, authentication information storage, authentication processing, and alarm processing units that authenticate users based on predefined actions within a target area, eliminating the need for monitoring units and optimizing energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If monitoring units such as cameras are used to detect unauthorized intrusion, then detection capability is improved, but device complexity and energy consumption increase

Engineering Contradiction:

Improveunauthorized intrusion detection capabilityVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the core authentication function from complex monitoring systems like cameras. Instead of using cameras to detect intrusion, the system extracts and analyzes only the necessary authentication actions (mobile terminal operations) to determine whether unauthorized intrusion has occurred, thereby simplifying the system structure while maintaining detection capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mobile terminal device itself performs authentication verification without requiring external monitoring units. The system uses the mobile terminal's own operational data (authentication actions) to verify user identity and detect unauthorized intrusion, eliminating the need for separate monitoring devices and reducing overall system complexity

Inventive Principle:

Principle #25Self-service

2Reliability

If monitoring units such as cameras are used to detect unauthorized intrusion, then detection capability is improved, but energy consumption increases

Engineering Contradiction:

Improveunauthorized intrusion detection capabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system extracts only the essential authentication action data from mobile terminal operations, ignoring all other unnecessary monitoring functions. This selective extraction of relevant information (authentication actions) dramatically reduces energy consumption compared to continuous camera monitoring while maintaining intrusion detection capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs authentication verification at specific intervals based on predetermined time periods after detecting authentication actions, rather than continuously monitoring. This periodic verification approach reduces energy consumption while still effectively detecting unauthorized intrusion attempts

Inventive Principle:

Principle #19Periodic action

3Reliability

If passwords are required for authentication, then security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveauthentication securityVSAvoiduser operation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical password input systems with automated analysis of mobile terminal authentication actions. Instead of requiring users to manually enter passwords, the system automatically verifies user identity by analyzing operational patterns (such as app launch sequences, button press patterns) of the mobile terminal, thereby maintaining security while significantly improving ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A mobile terminal device which a user carries includes: an entry determining unit for determining entry of the mobile terminal device in a residential area; an authentication information storage unit for storing authentication information indicating multiple authentication actions performed by the user carrying the mobile terminal device and an authentication order indicating an order of the authentication actions to be performed; an authentication processing unit for processing for authentication of the user by determining, based on the authentication information, whether or not the user has performed the authentication actions in the authentication order after the mobile terminal device enters the residential area; and an alarm processing unit for indicating a failure of the authentication when the result of the processing for the authentication is the failure.
