Door Locking System with Dual-Channel Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems face challenges in ensuring high functional reliability and easy operation, particularly when integrated with intruder alarm systems, as they often require manual key switches that can lead to accidental unlocking and trigger alarms if doors are opened before the system is disarmed.
Innovation Solution
Incorporating a remote control device with dual transmission channels and a receiving channel, allowing for wireless communication with the motor unit and intruder alarm system, where the second channel is used to arm/disarm the alarm system, preventing accidental unlocking by blocking the first channel until the alarm is disarmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual key switch is used to control unlocking, then the operation is simple, but the functional reliability is reduced due to accidental unlocking and alarm triggering
Solution Approach 1:
The patent replaces the manual mechanical key switch with an electronic remote control device that communicates wirelessly with the motor unit. This substitution eliminates the need for physical key insertion and switching, thereby preventing accidental unlocking while maintaining ease of operation through wireless remote control.
Solution Approach 2:
The patent introduces a control and receiving device as an intermediary between the user and the motor unit. This intermediary processes unlocking signals, validates alarm system status, and controls motor activation, thereby preventing direct accidental unlocking while maintaining a simple user interface through the remote control device.
2Ease of operation
If the door can be opened before the alarm system is disarmed, then the operation is convenient, but the alarm system may be accidentally triggered
Solution Approach 1:
The patent implements a preliminary check mechanism where the control and receiving device verifies the alarm system's disarmed status before allowing the motor unit to unlock the door. This preliminary validation prevents accidental alarm triggering by ensuring the system is in a safe state before door opening is permitted.
Solution Approach 2:
The patent applies preliminary anti-action by blocking the unlocking function when the alarm system is armed. The control and receiving device prevents the transmission of unlocking signals to the motor unit until the alarm system is properly disarmed, thereby counteracting potential harmful effects before they can occur.
3Adaptability or versatility
If a two-channel transmission device is used for locking and additional control, then the functionality is enhanced, but the device complexity increases
Solution Approach 1:
The patent implements a universal remote control device with multiple transmission channels that can control different functions (locking, unlocking, alarm disarming). This multi-functional approach consolidates multiple control operations into a single device, enhancing versatility without proportionally increasing complexity through integrated design.
Solution Approach 2:
The patent combines the locking control and alarm system control into a single integrated remote control device. By merging these functions into one device with multiple channels rather than separate devices, the overall system complexity is reduced while maintaining enhanced functionality.
