Digital Doorlock iBeacon Proximity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth doorlock systems experience delays and stability issues due to communication interruptions and require the doorlock application to be activated and within close proximity, leading to user inconvenience and insecurity.
Innovation Solution
A digital doorlock system that uses an iBeacon signal to reduce Bluetooth connection time, includes a keypad, Bluetooth beacon module, proximity sensor, and touch/pressure sensor to enable control even when the application is not activated, and a management server for user authentication and password management, minimizing delays and improving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth communication is used for doorlock control, then wireless convenience is improved, but communication delays and stability issues occur
Solution Approach 1:
The patent introduces a proximity sensor as an intermediary mechanism that detects when a user terminal is near the doorlock and automatically triggers Bluetooth connection. This mediator resolves the contradiction by enabling wireless control convenience while ensuring stable communication only when needed, avoiding the instability of continuous Bluetooth searching.
Solution Approach 2:
The proximity sensor performs preliminary detection of user presence before initiating Bluetooth connection. This preliminary action ensures that Bluetooth pairing is already established and stable before the user needs to control the doorlock, eliminating communication delays and stability issues during actual operation.
2Reliability
If Bluetooth connection period is extended to ensure stability, then communication reliability is improved, but power consumption and connection time increase
Solution Approach 1:
The system uses periodic proximity detection instead of continuous Bluetooth connection. The proximity sensor periodically checks for user presence and only activates Bluetooth when needed, achieving communication stability during critical moments while minimizing overall connection time and power consumption.
Solution Approach 2:
The Bluetooth connection duration is made dynamic rather than fixed. The connection is automatically established when proximity is detected and automatically disconnected after a set period or when control operations are complete, optimizing both reliability and time efficiency based on actual usage conditions.
3Reliability
If application activation is required for doorlock control, then security is improved, but ease of use deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting user proximity and initiating Bluetooth connection without requiring manual application activation. The proximity sensor triggers the entire authentication and connection process automatically, maintaining security through automated authentication while eliminating the inconvenience of manual app activation.
Solution Approach 2:
The manual mechanical action of activating an application is replaced by an automatic sensor-based system. The proximity sensor detects user presence and automatically initiates the Bluetooth connection and authentication process, substituting the need for manual application activation while maintaining security through automated credential verification.
