Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combination lock systems lack a secure and non-intrusive method to unlock when the user forgets the password, and they do not provide a record of unlocking attempts, compromising convenience and safety.
Innovation Solution
A combination lock system that integrates a mobile communication device, a cloud server, and a combination lock using NFC signals to authenticate and retrieve password information, allowing non-intrusive unlocking and recording of attempts, with a microcontroller and GPIO unit for power and data management, and a storage module for temporary record keeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a combination lock uses a password system, then security is improved compared to physical keys, but the lock cannot be unlocked if the user forgets the password
Solution Approach 1:
The patent introduces a mobile device as an intermediary that stores authentication information and communicates with the combination lock via NFC. This mediator enables alternative unlocking methods when the user forgets the password, resolving the contradiction between security and unlockability.
Solution Approach 2:
The patent adds a new dimension of authentication by incorporating cloud-based verification and mobile device communication. Instead of relying solely on the local password mechanism, the system transitions to a multi-dimensional authentication approach involving NFC signals, cloud servers, and wireless communication, enabling password recovery without compromising security.
2Device complexity
If the combination lock provides no unlocking record, then the system remains simple, but safety and monitoring capabilities are reduced
Solution Approach 1:
The patent implements preliminary action by pre-configuring the mobile device and cloud server to automatically record and store unlocking information before any unauthorized access can occur. The system proactively establishes a monitoring framework that captures authentication data, enabling safety monitoring without requiring complex additional hardware.
3Ease of operation
If the combination lock uses cloud authentication, then password recovery capability is improved, but system complexity and energy requirements increase
Solution Approach 1:
The patent replaces mechanical authentication systems with electronic and wireless communication mechanisms. NFC signals, wireless network communication, and electronic data storage substitute for traditional mechanical key and password systems, enabling cloud authentication while managing complexity through electronic integration rather than mechanical components.
Solution Approach 2:
The mobile device serves multiple functions: it acts as an authentication credential holder, communicates via NFC for proximity authentication, connects to wireless networks for cloud communication, and stores authentication data. This multi-functionality consolidates system complexity into a single universal device rather than requiring separate components for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, non-intrusive unlocking of the combination lock even if the user forgets the password, while providing a record of attempts to enhance safety and convenience by ensuring only authorized access and tracking malicious attempts.
Implementation Method 1
The mobile communication device outputs a first near field communication (NFC) signal... the combination lock obtains an electric energy and the password information from the mobile communication device through the first NFC signal
Implementation Method 2
When the combination lock determines that one of characters of the password setting module matches one of characters of the password information in a corresponding arrangement order...
Implementation Method 3
the combination lock outputs a display information to the mobile communication device through a second NFC signal... the combination lock outputs a combination lock record to the mobile communication device through the second NFC signal

AI summary
A combination lock system includes a mobile communication device (10, 10′), a cloud server (20) and a combination lock (30, 30′). When the cloud server (20) determines that the mobile communication device (10, 10′) matches authentication information, the cloud server (20) outputs password information (22) corresponding to the authentication information to the mobile communication device (10, 10′), and the combination lock (30, 30′) obtains an electric energy and the password information (22) from the mobile communication device (10, 10′). When the combination lock (30, 30′) determines that one of the characters of the password setting module (31, 31′) matches one of the characters of the password information (22) corresponding to a corresponding arrangement order, the mobile communication device (10, 10′) displays display information.
