Remote Control Door Locking System Using Knock Pattern Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current key-based locking systems are insecure due to key duplication inaccuracies, loss, and lack of flexible access control, as well as requiring physical key possession for access revocation, which can compromise security.
Innovation Solution
A temporary, keyless locking system that can be remotely operated using wireless communication or knock pattern recognition, allowing for flexible access control and enhanced security without the need for physical keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a key-based locking system is used, then access control is provided, but security is compromised due to key duplication inaccuracies, loss, and inability to revoke access
Solution Approach 1:
The patent replaces the mechanical key-based locking system with an electronic control system that uses a motorized mechanism to rotate the door knob. The electronic controller receives signals from remote devices or knock pattern detection to actuate the motor, which rotates the door knob to unlock the door, eliminating the need for physical keys and their associated security vulnerabilities.
Solution Approach 2:
The patent introduces an electronic controller as an intermediary between the user and the locking mechanism. The controller processes authentication inputs (remote signals or knock patterns) and controls the motorized door knob rotation, serving as a mediator that eliminates direct key insertion and provides centralized access control management.
2Adaptability or versatility
If electronic keypad systems are installed, then access control flexibility is improved, but device complexity and visibility increase
Solution Approach 1:
The patent creates a universal access control system that can accept multiple types of authentication inputs through a single device. The electronic controller can process both remote wireless signals and local knock pattern inputs, providing multiple access methods without requiring separate keypads or complex installations. The motorized door knob mechanism works with existing door hardware, making the system universally applicable.
3Adaptability or versatility
If key lockboxes are used, then multiple user access is enabled, but time consumption and security are increased due to physical key handling
Solution Approach 1:
The patent replaces the mechanical key lockbox system with an electronic control system that directly actuates the door knob motor. Multiple users can authenticate through remote devices or knock patterns without physically retrieving keys from a lockbox, eliminating the time-consuming key retrieval process while maintaining multi-user access capability through centralized electronic control.

AI summary
A portable, temporary removable system for locking and unlocking a door knob, door lever or locking deadbolt without the requirement of using keyed entry. Several manners of automated locking and unlocking are introduced and the instant system is designed for quick installation and removal. Once attached, the system may be remotely controlled from the outside of the door via a pattern of knocks, via electronic communications or a combination of a knock pattern and electronic communication.
