Solution Overview

Problem

Small establishments like restaurants and hotels face high operational costs due to the need for external management platforms and card readers for electronic door locks, making it expensive to set and manage electronic keys on a small scale.

Innovation Solution

An electronic door lock management method and system that allows for direct key setting through an induction zone, eliminating the need for external management platforms and card readers by using RFID cards and various user information acquisition methods like fingerprint, password, and remote control, to set and delete electronic keys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external management platform and card reader are used to set electronic keys, then the electronic door lock system achieves reliable key management, but the operating cost and device complexity increase significantly

Engineering Contradiction:

Improveelectronic key management reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the key management function from the external management platform and card reader, and integrates it directly into the electronic door lock body. The lock can now acquire card information, fingerprints, passwords, and other authentication data directly, eliminating the need for separate management platforms and card readers while maintaining reliable key management.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The electronic door lock is designed to perform multiple functions: it can acquire card information from various types of cards (access cards, file cards, logout cards), capture fingerprints, receive passwords, and manage electronic keys all within a single device. This multi-functionality consolidates previously separate systems into one unified lock unit.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If external management platform and card reader are deployed, then comprehensive key setting capability is achieved, but the cost for small-scale applications becomes prohibitive

Engineering Contradiction:

Improvekey setting capabilityVSAvoiddeployment cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines the functions of the management platform and card reader with the electronic door lock into a single integrated system. By merging these previously separate components, the solution eliminates the need for expensive external infrastructure while maintaining comprehensive key setting capabilities including card-based, fingerprint-based, and password-based authentication.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If traditional management platform is used, then secure key management is achieved, but the operation complexity and maintenance cost increase

Engineering Contradiction:

Improvekey management securityVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The electronic door lock performs key management operations autonomously without requiring external management platforms. The lock itself acquires authentication information from cards, fingerprints, or passwords, and independently manages the electronic keys, thereby simplifying operation while maintaining security through self-contained functionality.

Inventive Principle:

Principle #25Self-service
