Bi-directional Electronic Lock Automatic Direction Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bi-directional electronic lock devices require manual setting to operate correctly on left-handed or right-handed doors, which is prone to human errors and can lead to incorrect operation or component damage.
Innovation Solution
A bi-directional electronic lock device with a control unit that includes a position determining component, sensor, direction determining module, and control module, allowing for automatic setup by actuating the lock mechanism to generate directional signals based on sensor inputs, thereby determining the correct setting for the door type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual setting is used to configure the electronic lock device for left-handed or right-handed doors, then the device can be set up, but human errors occur leading to incorrect operation or component damage
Solution Approach 1:
The electronic lock device automatically detects whether it is installed on a left-handed or right-handed door through self-testing operations, eliminating the need for manual configuration by users. The device performs automatic direction determination and setting based on sensor feedback during automated lock/unlock cycles, thereby preventing human errors while maintaining ease of installation.
Solution Approach 2:
The system performs preliminary automatic testing operations before normal use to determine the correct operating direction. The control unit executes a series of automated lock and unlock cycles, monitors sensor signals during these cycles, and pre-determines the appropriate setting (left-handed or right-handed) before the user completes installation, ensuring correct configuration from the start.
2Reliability
If automatic setup is implemented to eliminate human error, then operation reliability improves, but device complexity increases
Solution Approach 1:
The control unit monitors feedback signals from sensors during automated lock and unlock operations to determine the correct operating direction. By analyzing the sequence and state of sensor signals during self-testing cycles, the system automatically identifies whether the device is installed on a left-handed or right-handed door and configures itself accordingly, achieving high setup accuracy without requiring overly complex external mechanisms.

AI summary
A bi-directional electronic lock device includes a lock mechanism and a control unit. The control unit includes a position determining component driven by the lock mechanism to rotate, a sensor configured to generate a specific sensing signal for each of three positions with respect to the position determining component, a direction determining module that actuates the lock mechanism to move from a locked state toward an unlocked state, and that generates a directional signal based on the sensing signals, and a control module that is configured to, in response to receipt of the directional signal, set the lock mechanism, based on the directional signal, to operate in one of a left setting and a right setting.
