Wireless Lock Control via Motion Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart door unlocking methods using short-range wireless communication require users to physically interact with the door, leading to security issues when the door is unlocked prematurely or when devices do not support wireless communication.
Innovation Solution
An electronic device provides a user interface for unlocking, allowing users to perform specific inputs, and includes a sensor to detect motion or rotation, transmitting authentication information to unlock the door wirelessly, eliminating the need for physical interaction and ensuring secure unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If short-range wireless communication is used to unlock the smart door, then user convenience is improved, but security risks increase due to premature unlocking
Solution Approach 1:
The system performs preliminary authentication by detecting specific user actions (muscle movement, gripping lever, knocking) before transmitting the unlock signal. This preliminary detection ensures that unlocking only occurs when the authorized user is physically present and performing the intended action, preventing premature unlocking while maintaining convenience.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism between the user and the door lock. Instead of direct wireless unlocking, the system uses motion sensors, muscle sensors, or impact sensors as intermediaries to verify user intent and identity before authorizing the unlock operation, thereby enhancing security without compromising ease of use.
2Loss of time
If the electronic device is merely connected to the smart door for unlocking, then unlocking speed is improved, but security problems occur due to advance unlocking
Solution Approach 1:
The system establishes a preliminary connection between the electronic device and smart door, but delays the actual unlock action until specific user gestures are detected. The connection is prepared in advance (improving speed), but the unlock trigger is conditional on real-time user action detection (maintaining security).
Solution Approach 2:
The system transitions from a static connection state to a dynamic trigger-based unlock mechanism. The connection exists beforehand, but the unlock function dynamically activates only when sensor-detected user actions confirm legitimate access intent, balancing speed and security.
3Reliability
If physical interaction with the door is required for unlocking, then security is improved, but compatibility issues arise with devices not supporting short-range wireless communication
Solution Approach 1:
The smart door system is designed with multi-functionality to support both wireless unlocking (for devices with short-range communication) and physical interaction-based unlocking (for devices without). The door can detect muscle movements, gripping actions, or knocking sounds universally, making it compatible with various device types while maintaining security through physical action verification.
Solution Approach 2:
The patent uses physical sensors (muscle sensors, impact sensors, vibration sensors) as universal intermediaries that can detect user actions regardless of the electronic device type. This intermediary layer ensures compatibility with both wireless-capable and wireless- incapable devices while maintaining security through physical interaction verification.
