Auxiliary Door State Sensor Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system to share state information of auxiliary doors, such as balcony doors, to inform guests if they are open or unlocked, as they often forget to close and lock these doors, posing a security risk.
Innovation Solution
A system comprising a main locking device with a communication module and an auxiliary door with a state sensor that detects and transmits the state information (open, closed, locked, or unlocked) to the main locking device or room management system, which then sends notifications to the guest via a mobile device or status indicator when the door is left open or unlocked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simplistic latching mechanism is used for auxiliary doors, then the device complexity is reduced and ease of operation is improved, but security reliability deteriorates because guests forget to close and lock the door
Solution Approach 1:
The system continuously monitors the state of the auxiliary door through sensors and provides real-time feedback to guests via notifications when the door is left open or unlocked. This feedback mechanism reminds guests to secure the door without adding physical complexity to the latching mechanism itself.
Solution Approach 2:
A communication module acts as an intermediary between the door state sensors and the guest's mobile device. This intermediary transmits state information and sends reminders, bridging the gap between the simple mechanical door and the guest's awareness, thereby improving security without complicating the door mechanism.
2Reliability
If state sensors and communication modules are added to monitor auxiliary door status, then security reliability is improved, but device complexity increases
Solution Approach 1:
The main locking device serves multiple functions: it acts as both a traditional locking mechanism and a central hub for receiving state information from auxiliary door sensors and communicating with guests. This multi-functionality reduces the need for separate dedicated devices, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system uses existing infrastructure components (mobile devices of guests, room management systems) to handle communication and notification tasks. Rather than requiring a complex dedicated notification system, the system leverages the guest's own device for alerts, reducing the complexity burden on the door monitoring system itself.
3Reliability
If real-time notifications are sent to guests about door state, then security reliability is improved, but use of energy increases due to continuous monitoring and communication
Solution Approach 1:
Instead of continuous active communication, the system uses event-triggered periodic action: notifications are sent only when the door state changes or when the system detects the guest is leaving the room. This approach maintains security monitoring while significantly reducing energy consumption compared to continuous real-time communication.
Solution Approach 2:
The system detects preliminary indicators (such as rotation of the interior door handle) that suggest the guest is leaving, and proactively sends notifications before the guest actually exits. This preliminary action allows the system to alert guests in advance, maintaining security while reducing the frequency and energy cost of notifications.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively informs guests of the state of auxiliary doors, prompting them to close and lock these doors, thereby enhancing security by ensuring they are aware of their status when leaving the room.
Implementation Method 1
The state sensor includes at least one reed switch and at least one magnet
Implementation Method 2
The rotation sensor of the interior door handle is configured to detect the rotation of the interior door handle
Implementation Method 3
The notification is transmitted using at least one of: Wi-Fi, Bluetooth, Bluetooth Low Energy (BTLE), Zigbee, infrared, and cellular

AI summary
A system and method for sharing state information of an auxiliary door are provided. The system includes a main locking device and an auxiliary door with a state sensor. The state sensor is configured to detect and transmit state information to at least one of the main locking device and a room management system. The state information may include whether the auxiliary door is in an opened state, a closed state, a locked state, and/or an unlocked state. The main locking device is configured to transmit a notification based on the state information when a rotation sensor detects the rotation of an interior door handle and the state information indicates that the auxiliary door is in the opened state and/or the unlocked state. This notification may be sent to a mobile device and/or a status indicator.
