Digital Key Management for Lock Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locks require multiple physical keys and mechanical structures that are prone to compromise, making them inconvenient and insecure for managing access.
Innovation Solution
A method using a mobile device to register accounts and generate digital keys for lock management, allowing for secure unlocking operations through various identification patterns, including quick pass, single, and double identification patterns, and enabling remote authority granting and revocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional locks use mechanical structures and metal keys, then unlocking functionality is provided, but users must carry multiple keys and memorize key-lock associations, reducing convenience
Solution Approach 1:
The patent replaces physical metal keys with digital copies stored in mobile devices. Multiple virtual keys can be created and stored electronically, eliminating the need to carry multiple physical keys while maintaining the ability to unlock multiple locks. The digital key system allows users to manage all keys through a single mobile device interface.
Solution Approach 2:
The patent substitutes the mechanical key-lock system with an electronic/digital system. Instead of inserting physical metal keys into mechanical lock cores, users interact with a lock application on their mobile device that communicates with the lock through wireless or electronic interfaces, thereby replacing the entire mechanical interaction paradigm.
2Reliability
If conventional locks use mechanical structures, then unlocking functionality is achieved, but the mechanical structures tend to be compromised, reducing security
Solution Approach 1:
The patent replaces the vulnerable mechanical key-lock structure with an electronic system where security relies on digital authentication protocols and encrypted communication between the mobile device and lock. This eliminates the physical mechanical components that can be analyzed, picked, or duplicated through traditional means.
Solution Approach 2:
The patent changes the fundamental parameter of key delivery from physical to digital. Instead of transmitting security through the physical presence and insertion of a metal key, the system uses electronic parameters such as encrypted data packets, authentication tokens, and wireless communication protocols to verify and execute the unlocking function.
3Reliability
If digital key management is implemented, then convenience and security are improved, but multiple identification patterns and authentication steps are required
Solution Approach 1:
The patent implements dynamic identification patterns that can adapt to different situations. The system offers multiple authentication modes (quick pass pattern, single identification pattern, double identification pattern) that can be selected based on security requirements and user preferences, allowing the unlocking procedure to be flexible rather than fixed.
Solution Approach 2:
The patent segments the authentication process into distinct patterns or modes. Each pattern represents a separate authentication pathway with different levels of verification steps. Users can choose the appropriate segmentation level based on the situation, from rapid single-step authentication to more secure multi-step verification processes.

AI summary
A method for operating a lock device includes installing a lock device application (lock APP) into a mobile device. A first identification information and a second identification information are inputted into the mobile device under guidance of the lock APP The lock APP can be connected with a lock device within a communication range of the mobile device. Then, a hardware serial number of the lock device is inputted into the mobile device to obtain the management authority of the lock device. A manager electronic key formed by the mobile device with the management authority of at least one lock device can grant the unlocking authority of a selected lock device to another user whose account name is provided to the manager electronic key. The unlocking procedure can be carried out based on one of a quick pass pattern, a single identification pattern, and a double identification pattern.
