Innovation Solution
An adaptive electric dual-controlled intelligent lock that integrates a mechanical clutching structure with an intelligent electronic control system, allowing for dual unlocking methods using both traditional keys and mobile intelligent terminals, and can be installed on existing mechanical letter lock cylinders without replacing the letter box, utilizing a PCB, motor, shifting lever, and wireless connectivity for remote control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mechanical letter lock cylinders are completely replaced with intelligent letter box systems, then intelligent control functionality is improved, but installation complexity and cost increase significantly
Solution Approach 1:
The invention divides the intelligent locking system into two independent parts: the existing mechanical letter lock cylinder (which remains unchanged) and a separately installed intelligent control device. This segmentation allows the mechanical structure to be preserved while adding intelligent functionality through a modular approach, reducing installation complexity and avoiding complete system replacement.
Solution Approach 2:
The intelligent control device is designed to be universally compatible with traditional mechanical letter lock cylinders through standardized mounting interfaces and universal control protocols. This multi-functionality enables the same intelligent controller to work with various mechanical lock types, facilitating easy integration without requiring custom solutions for each lock model.
2Adaptability or versatility
If traditional mechanical letter lock cylinders are completely replaced with intelligent letter box systems, then intelligent control functionality is improved, but installation time and labor cost increase
Solution Approach 1:
The intelligent control device is pre-configured with mounting brackets, fastening components, and control software before installation. The device arrives ready-to-install with all necessary hardware pre-attached, eliminating the need for on-site assembly or customization. This preliminary preparation significantly reduces installation time and allows for quick deployment in existing letter box systems.
3Extent of automation
If traditional key unlocking systems are replaced with mobile intelligent terminal control, then automation level is improved, but user accessibility and ease of operation deteriorate for elderly users
Solution Approach 1:
The locking system dynamically adapts to different user needs by supporting multiple unlocking modes: traditional mechanical key unlocking for users who prefer or require conventional methods, and mobile terminal control for users who want automated access. The system can switch between these modes based on user preference, age, and situation, ensuring accessibility for all user groups including elderly users who may not be comfortable with smartphone technology.

Implementation Method 1
the intelligent electronic control structure comprises a PCB (printed circuit board), a motor and a shifting lever, wherein: the PCB is electrically connected with the motor
Implementation Method 2
the lock cylinder comprises two movable buckles, two springs and a bearing, wherein one end of each of the springs is fixed on the bearing, the other end of each of the springs is fixed on each of the movable buckles; a keyhole of the lock head is opposite to a locked groove defined by the movable buckles, the lock tongue is in detachable connection with the bearing, so that after being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles respectively move in an elastic range of the springs

AI summary
An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.
