Solution Overview

Problem

Electronic locking devices face security issues due to unauthorized access when authentication information is leaked, as they rely solely on single authentication methods, lacking robust dual authentication mechanisms.

Innovation Solution

A dual authentication system using an electronic key that performs wireless communication with a mobile terminal, combining UID data and encoding data authentication to securely unlock the device, including a receiving unit, authentication unit, and command unit for secure dual authentication and logging of authentication events.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If single authentication method is used in electronic locking device, then ease of operation is improved, but security is deteriorated due to unauthorized access when authentication information is leaked

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The authentication process is divided into two separate authentication methods: first authentication based on authentication information (password, fingerprint, etc.) and second authentication based on encoding data generated by button input. Both authentication results must be successful for the door to unlock, creating a segmented multi-layer security system that maintains ease of use while significantly improving security.

Inventive Principle:
Principle #1Segmentation

2Reliability

If dual authentication is implemented, then security is improved, but device complexity is worsened

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control unit integrates both authentication processes (first authentication based on authentication information and second authentication based on encoding data) into a single unified control mechanism. The control unit receives results from both authentication methods and makes the final unlock decision based on the combination of both results, merging the dual authentication processes into one cohesive system that improves security without requiring separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If mechanical locking device is used, then security is improved through physical key control, but ease of operation is worsened due to key loss and replacement needs

Engineering Contradiction:
ImprovesecurityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system replaces the traditional mechanical key-based locking system with an electronic authentication system. Instead of using a physical key that can be lost or stolen, the system uses electronic authentication information (password, fingerprint, etc.) combined with encoding data generated by button input. This substitution eliminates the problems associated with mechanical keys while maintaining security through dual authentication.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
