Solution Overview
Problem
Current smart lock systems face vulnerabilities such as power failures, hacking risks, limited access channels, and lack of real-time control, making them insecure and inconvenient for users, especially when relying on RFID technology or smartphones.
Innovation Solution
A smart lock system with redundant access channels, including biometric scanners, passcode keypads, and wireless transceivers, that allows administrators to control access rights in real-time through a mobile device, providing flexible access permissions and incorporating redundant power sources to prevent power failures, while also featuring a rose protector mechanism to prevent vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single access channel (e.g., RFID button) is used in smart locks, then the device complexity is reduced and ease of operation is improved, but the reliability and security are worsened due to vulnerability to power failures, hacking, and vandalism
Solution Approach 1:
The lock system is segmented into multiple independent access channels (RFID button, biometric scanner, passcode keypad, wireless transceiver) that can function separately. Each channel processes authentication independently, so failure of one channel does not compromise the entire system. This segmentation provides redundancy while maintaining manageable complexity through modular design.
Solution Approach 2:
The system incorporates redundant power sources (primary battery and secondary power source) and multiple access channels before failures occur. When power failure or hacking is detected,备用 access channels and power sources are already in place to maintain operation, cushioning against potential failures before they impact system reliability.
2Reliability
If multiple redundant access channels are added to smart locks, then the reliability and security are improved, but the device complexity and installation difficulty are worsened
Solution Approach 1:
Multiple access channels (biometric scanner, passcode keypad, wireless transceiver) are merged into a single integrated lock body. This consolidation allows redundant functionality to be achieved without proportionally increasing installation complexity, as all channels share common mounting and power infrastructure.
Solution Approach 2:
The lock system is designed with universal multi-functionality, where a single device provides RFID, biometric, passcode, and wireless access capabilities. This multi-functional design reduces the need for multiple separate devices or complex custom installations, making the system easier to manufacture and install while maintaining high reliability through redundancy.
3Adaptability or versatility
If surface-mounted locks with embedded wireless transceivers are used, then wireless communication capability is improved, but the installation complexity and vulnerability to battery failure are worsened
Solution Approach 1:
The system incorporates a secondary power source as a pre-prepared backup against battery failure. When the primary battery in the wireless transceiver is depleted or fails, the secondary power source automatically or manually takes over, maintaining wireless communication capability and preventing lockout. This beforehand cushioning ensures reliability despite battery dependency.
4Ease of operation
If cylinder-based smart locks with freely rotating pivot are used, then ease of installation and autonomous operation are improved, but the security against vandalism is worsened
Solution Approach 1:
The system implements preliminary anti-action against vandalism by incorporating multiple authentication channels and a disabled state. Before a vandal can successfully compromise the lock through brute force rotation, the system requires valid authentication through one of multiple channels. The freely rotating pivot is counterbalanced by electronic authentication requirements and the ability to disable the mechanism, preventing unauthorized access despite mechanical vulnerability.

AI summary
Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidabiy interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information, The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.
