Smart Door Lock E-Paper Display for Area Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital door locks lack the ability to display door-lock area information and user information externally, leading to user inconvenience and potential interference from third parties due to lack of communication and information sharing capabilities.
Innovation Solution
A smart door lock system with an e-paper display that shows door-lock area information, including state and user information, using a combination of RFID cards, smart terminals, and short-range wireless communication to manage and transmit lock/unlock codes and area settings, allowing for both online and offline operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional digital door locks are used, then the lock can perform basic locking and unlocking functions, but the lock cannot provide door-lock area information or user status information to third parties
Solution Approach 1:
The patent introduces an e-paper display as an intermediary component between the door lock system and third parties. This display module visually presents door-lock area information and user status without requiring complex communication protocols or additional active components, thereby resolving the contradiction by adding information display capability while maintaining relatively simple system architecture.
Solution Approach 2:
The door lock system is enhanced to serve multiple functions: it not only performs basic locking and unlocking but also displays door-lock area information and user status. By integrating the e-paper display with the existing lock mechanism, the system achieves multi-functionality without requiring completely separate systems, thus improving information availability while controlling complexity.
2Ease of operation
If conventional digital door locks are used, then the device structure remains simple, but users cannot notify third parties of their status and third parties may interfere with users
Solution Approach 1:
The e-paper display acts as a mediator that communicates user status and door-lock area information to third parties. This visual communication channel allows users to notify others of their status without requiring active user intervention or complex communication protocols, thereby improving ease of operation while preventing third-party interference through information transparency.
Solution Approach 2:
The door lock system automatically displays relevant information on the e-paper display without requiring users to manually notify third parties. The system self-manages the communication of status information, eliminating the need for active user participation in notification processes while effectively preventing third-party interference.
3Loss of information
If conventional digital door locks are used, then the system consumes minimal power, but the lock cannot provide any information to third parties outside the door
Solution Approach 1:
The patent employs an e-paper display technology that consumes minimal power, comparable to traditional display methods. E-paper displays maintain their visual state without continuous power supply, allowing the door lock system to provide information to third parties while maintaining energy consumption levels similar to conventional locks, thus resolving the contradiction between information provision and power consumption.

AI summary
A smart door lock system and a control method thereof are proposed. More specifically, in the smart door lock system and the control method thereof, door-lock area information is displayed on an outer side of a door, the door-lock area information including: any one or more pieces of door-lock area state information on states of a door lock area entered through a door lock in which a smart door lock is installed; and door-lock area user information of users who use the door lock area.
