Remote Control Door Locking System with Knock Recognition

The patent replaces the mechanical key-based locking system with an electronic control system that uses a motor to rotate the door knob. The electronic controller receives signals from remote devices or keypads to actuate the motor, eliminating the need for physical keys and their associated security vulnerabilities.

The patent creates multiple electronic access copies (remote devices, keypads) that can grant access without duplicating a physical key. Each remote device or keypad code serves as a virtual copy of access authority, allowing multiple users to access the lock without creating duplicatable physical keys.

The patent replaces physical key distribution with electronic access methods including remote devices and keypads. This eliminates the need to physically manage multiple keys, track their locations, and revoke access by collecting physical keys.

The system allows users to independently use their own remote devices or enter keypad codes to gain access. Each user manages their own access credentials without requiring physical key distribution or collection from a central authority.

The patent eliminates the intermediate step of retrieving a physical key from an electronic lockbox by directly actuating the door knob lock through a motor. The electronic controller receives signals and immediately triggers the motor to rotate the door knob, providing direct access without key retrieval.

The patent extracts the key function entirely from the system. Instead of providing keys that users must retrieve and insert, the system directly provides the unlocking action through motor actuation, removing the unnecessary intermediate step of key handling.
