Door Notification System Using Short-Range Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems that provide notifications of door opening/closing states to all registered electronic devices are inefficient, as they send notifications to devices that do not need them, wasting resources and being of little use to the user who performed the action.
Innovation Solution
The system identifies the user who opened or closed the door by comparing information from the server and the door's communication units, ensuring notifications are only sent to devices that need them, using a combination of long-distance and short-range communication methods to differentiate between registered and non-registered users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notifications are sent to all registered electronic devices when door opening/closing state changes, then all users are informed of door status changes, but resources are wasted and users who performed the action receive unnecessary notifications
Solution Approach 1:
The patent extracts the electronic device that performed the door opening/closing action from the notification recipient list. By identifying the device through short-range communication and comparing it with the list of registered devices, the system excludes the performing device from receiving notifications, thereby eliminating unnecessary energy consumption while maintaining complete information delivery to all other users.
Solution Approach 2:
The system implements feedback by having the electronic device perform short-range communication with the door to obtain identification information, then comparing this information with the registered device list. This feedback mechanism enables the system to intelligently determine which devices should receive notifications, optimizing resource usage while ensuring reliable delivery.
2Loss of energy
If notifications are sent only to differentiate registered and non-registered users, then resource efficiency is improved, but the system complexity increases due to multiple communication methods and identification processes
Solution Approach 1:
The patent segments the user group into registered users (with electronic devices) and non-registered users (without electronic devices). This segmentation allows the system to apply different notification strategies: sending notifications to all registered devices while excluding the performing device, and sending notifications to all users including non-registered ones. This segmentation simplifies the decision logic despite the presence of multiple communication methods.
Solution Approach 2:
The server acts as an intermediary that manages the notification distribution logic. It receives door state changes, identifies the performing device through short-range communication data, compares it with the registered device list, and determines the final notification recipient list. This intermediary approach centralizes the complexity in the server rather than in each electronic device, simplifying the overall system architecture.
3Loss of energy
If the system identifies the user who opened/closed the door through communication between door and electronic device, then unnecessary notifications are reduced, but the detection and measurement process becomes more complex
Solution Approach 1:
The door is equipped with both long-range communication capability (for server communication) and short-range communication capability (for direct electronic device communication). This multi-functionality allows the door to serve multiple purposes: it can communicate with the server for registration management and with electronic devices for identification, simplifying the overall detection process by consolidating multiple functions in a single device.
Solution Approach 2:
Electronic devices are pre-registered with the server before use, and the door is pre-configured with both communication capabilities. This preliminary setup eliminates the need for complex real-time identification processes during door operations, as the system already has the necessary information and capabilities in place to quickly determine which device performed the action.

AI summary
An electronic device is disclosed. The electronic device includes: a first communication unit and a second communication unit; a processor; and a memory, wherein the memory includes instructions causing the processor to control the first communication unit to receive first identification information for the door and first opening/closing state information of the door from a server, control the second communication unit to receive second communication unit to receive second door identification information and second opening/closing state information of the door from a door, and identify information on an electronic device involved in a change in an opening/closing state of the door based on the first identification information for the door, the first opening/closing state information of the door, the second door identification information, and the second opening/closing state information of the door. Other various embodiments are possible.
