IoT Smart Lock Password Sharing for Remote Multi-Lock Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door locks require physical proximity cards or manual password entry, which are prone to loss or forgetfulness, and managing multiple locks is laborious for landlords or hotel managers.
Innovation Solution
An IoT device password sharing system comprising a cloud server, first and second smart devices, and smart locks, enabling remote password management and sharing through an application software, with authentication, configuration, and storage modules for efficient lock control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If proximity cards are used for door locks, then security and speed of access are improved, but the risk of loss and inconvenience of carrying physical cards increases
Solution Approach 1:
The patent replaces physical proximity cards with digital copies stored in mobile devices. The password sharing system generates virtual password copies that can be transmitted electronically, eliminating the need for physical card carriers while maintaining quick access functionality.
Solution Approach 2:
The patent substitutes the mechanical proximity card system with an electronic password sharing system. Instead of using physical cards and card readers, the system uses mobile devices with communication capabilities to transmit and validate passwords, replacing the entire mechanical card-based authentication mechanism.
2Ease of operation
If passwords are used for door locks, then the inconvenience of carrying physical cards is eliminated, but the time required for authentication and the problem of forgetting passwords increases
Solution Approach 1:
The patent implements preliminary action by pre-generating and storing multiple password copies in the cloud server before they are needed. When a user needs access, they can immediately retrieve a pre-prepared password without waiting for generation or complex authentication processes, significantly reducing authentication time.
Solution Approach 2:
The system enables self-service by allowing users to automatically retrieve and use password copies from the cloud server without requiring manual intervention from administrators. The mobile device automatically communicates with the server to obtain authentication credentials, eliminating the need for users to remember passwords or request new ones manually.
3Reliability
If multiple door locks are managed manually, then security control is maintained, but the labor and time required for management and allocation of credentials increases
Solution Approach 1:
The patent implements universality by creating a single cloud server system that can manage multiple door locks and multiple users simultaneously. The server provides universal password generation and distribution capabilities that work across different locks and users, eliminating the need for separate management systems for each lock and reducing administrative workload.
Solution Approach 2:
The cloud server acts as an intermediary between administrators and multiple door locks/users. Instead of manually managing each lock individually, the server mediates the entire authentication credential distribution process, automatically generating, storing, and distributing passwords to authorized users, thereby significantly improving management efficiency while maintaining security.

AI summary
An IoT device password sharing system comprises a cloud server, at least one first smart device, at least one second smart device and at least one smart lock, and is connected to the cloud server through an application software of the first smart device, thereby setting a password message for the smart lock remotely, and transmitting the password message to the second smart device through the cloud server, and the second smart device is capable of opening the password message through an application software thereof and sharing the received password message, thereby achieving an object of opening the smart lock.
