Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration is used to set left-open or right-open settings, then the electronic lock can be adapted to different door types, but human error occurs leading to incorrect locking and unlocking operations
Solution Approach 1:
The electronic lock automatically detects the door type and configures the opening mode without requiring manual intervention. The control module autonomously determines whether the door is a left-hand or right-hand door by monitoring the rotation direction of the turning-piece module during installation, and automatically sets the corresponding opening mode, eliminating human error in configuration.
Solution Approach 2:
The system uses feedback from Hall sensors to detect the position and rotation direction of the magnetic component on the turning-piece module. This feedback information is processed by the control module to automatically determine the door type and configure the appropriate opening mode, ensuring accurate adaptation to different door types without manual intervention.
2Adaptability or versatility
If manual setting is performed, then the electronic lock can be configured for specific door types, but malfunctions and damages may occur due to incorrect setup
Solution Approach 1:
The electronic lock performs self-configuration by automatically detecting the door type through the rotation direction of the turning-piece module and setting the appropriate opening mode. This eliminates manual configuration errors that could lead to malfunctions or damages, as the system autonomously ensures correct setup for the specific door type.
Solution Approach 2:
The system prevents potential malfunctions and damages by proactively automatically configuring the correct opening mode before any locking or unlocking operations are performed. By detecting the door type during installation and pre-setting the appropriate mode, the system prevents incorrect operations that could cause harm.
3Reliability
If automatic detection using Hall sensors and magnetic component is implemented, then human error is reduced, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical configuration with an automatic detection system using Hall sensors and a magnetic component. The Hall sensors detect the position and rotation direction of the magnetic component on the turning-piece module, providing automated feedback to the control module for determining door type and setting the opening mode, thereby eliminating manual intervention and improving reliability.
Solution Approach 2:
The control module serves multiple functions: it controls the electronic driving module for locking and unlocking operations, detects the door type through Hall sensor feedback, automatically determines the opening mode, and drives the turning-piece module during installation. This multi-functionality reduces the need for separate configuration mechanisms, balancing automation with reasonable complexity.

AI summary
An electronic lock includes a locking mechanism and a control device. The locking mechanism includes an electronic driving module, a deadbolt, and a turning-piece module configured to be driven by the electronic driving module or to be manually operated to rotate among a first position, a second position and a third position, and to drive the deadbolt to move while rotating. The control device includes three Hall sensors surrounding a rotation axis of the turning-piece module, a magnetic component co-rotatable with the turning-piece module relative to the Hall sensors, and a control module. Each Hall sensor generates a sensing signal upon detecting the magnetic component. The control module is configured to activate a left-open setting or a right-open setting according to two sensing signals that are first received respectively from two of the Hall sensors without controlling the electronic driving module to drive the turning-piece module to rotate.
