Unlocking method and system for air conditioner unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning units rely on fixed passwords, which pose safety risks due to potential unauthorized access and password forgetfulness or brute-force attacks, necessitating a dynamic and secure login method.
Innovation Solution
An unlock method and system that generates a dynamic graphic and unlock password based on an identification code and update code, using a certificate, and verifies the input password through a user terminal device and server, ensuring secure and dynamic user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed password is used for login, then the system is simple to operate, but the security is compromised due to unauthorized access and brute-force attacks
Solution Approach 1:
The patent implements dynamic password generation where the password changes over time based on time intervals and random factors. The control apparatus generates different passwords at different times, making each login attempt unique and preventing brute-force attacks while maintaining operational simplicity for authorized users
Solution Approach 2:
The patent introduces a server as an intermediary between the user terminal and the control apparatus. The server manages password generation, validation, and distribution, separating the security complexity from the user interface while enabling secure authentication through coordinated interaction between multiple system components
2Reliability
If a fixed password is used, then the login process is simple, but the password can be easily forgotten or brute-forced
Solution Approach 1:
The system automatically generates and manages passwords without requiring user memorization. The control apparatus and server handle password creation, storage, and distribution autonomously, sending passwords to authorized user terminals while preventing unauthorized access, thus maintaining convenience while enhancing security
3Reliability
If a dynamic password system is implemented, then security is improved, but the system complexity increases
Solution Approach 1:
The patent divides the authentication system into distinct functional modules: the control apparatus that generates passwords, the server that manages validation and distribution, and the user terminal that receives and uses passwords. This segmentation allows each component to perform its function independently, managing complexity through modular design while achieving secure dynamic authentication

AI summary
An unlock method and system for an air-conditioning unit. The unlock system includes: a display apparatus; an input apparatus; and a control apparatus in communication with the display apparatus and the unlock system is configured to perform the following operations: generating a dynamic graphic according to at least an identification code and an update code; generating an unlock password according to at least a certificate, the identification code and the update code; receiving an unlock password through the input apparatus; comparing the unlock password received from the input apparatus with the generated unlock password; and granting a corresponding permission if the acquired unlock password is consistent with the generated unlock password.
