Solution Overview

Problem

Existing digital door lock systems are vulnerable to hacking and unauthorized password changes due to weak security in user and administrator codebooks, posing a risk of unauthorized access.

Innovation Solution

A method is introduced to grant administrator authority only through a smart device with a generated administrator password, allowing secure password resetting and management via a door lock management app, enhancing security by requiring input of a unique administrator password for linking and managing the door lock.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional password authentication methods are used in digital door lock systems, then ease of operation is improved, but security is worsened due to vulnerability to hacking and unauthorized password changes

Engineering Contradiction:
Improvepassword authenticationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a door lock management server as an intermediary between the mobile terminal and the door lock. This server acts as a trusted mediator that generates and manages one-time passwords, preventing direct exposure of authentication credentials and eliminating the need for users to manually manage complex passwords while maintaining high security standards.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If user codebooks are used for password management, then ease of operation is improved, but security is worsened due to risk of acquiring administrator authority and arbitrary password changes

Engineering Contradiction:
Improvecodebook managementVSAvoidadministrator authority security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the authentication system into distinct components: user codebooks for regular users and a separate administrator password protection mechanism. The administrator password is stored and verified by the door lock management server, creating a segmented security architecture where password management functions are separated from user authentication functions, preventing unauthorized access to administrator capabilities.

Inventive Principle:
Principle #1Segmentation

3Reliability

If real-time communication between mobile terminal and server is implemented, then security is improved through password generation and changes, but device complexity is worsened

Engineering Contradiction:
ImprovesecurityVSAvoidsystem architecture
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The door lock management server automatically generates one-time passwords and handles authentication without requiring manual intervention from users. The server self-manages the security infrastructure, including password generation, verification, and updating, which simplifies the user interface while maintaining robust security through automated server-side processes.

Inventive Principle:
Principle #25Self-service
