Home Network Door Lock Temporary Access via Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital door locks require pre-notification of temporary access codes to visitors, risking unauthorized disclosure and frequent password changes, lacking integration with wireless communication systems for secure and convenient temporary access management.
Innovation Solution
A method for controlling a door lock within a home network system, where release information is generated and managed through a gateway connected to a communication network, allowing temporary users to access the door lock via smart terminals, with usage settings for time-limited access, eliminating the need for code sharing and periodic password changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a permanent access code is provided to temporary users, then they can access the house or office, but the code may be disclosed to unauthorized users and requires periodic changes
Solution Approach 1:
The access code functionality is segmented into temporary and permanent codes. The temporary access code is generated separately from the permanent code stored in the door lock, allowing independent management of temporary user access without affecting the main security system.
Solution Approach 2:
The patent implements disposable temporary access codes that are generated for specific time periods or single-use occasions. These temporary codes expire automatically after their designated period, eliminating the need for periodic changes and reducing security risks associated with code disclosure.
2Ease of operation
If the door lock operates independently without network integration, then it maintains simple operation, but it cannot provide convenient temporary access management for visitors
Solution Approach 1:
The gateway serves as an intermediary device between the door lock and the external network. It receives temporary access code generation requests from external terminals, processes them, and transmits the generated codes to both the gateway and the temporary users, enabling convenient remote access management without requiring the door lock itself to be complex.
Solution Approach 2:
The gateway device performs multiple functions: it acts as a communication bridge between the door lock and external networks, generates temporary access codes, manages user requests, and distributes codes to authorized users. This multi-functionality enables convenient temporary access management while keeping the door lock itself relatively simple.
3Loss of time
If the permanent access code is notified to temporary users in advance, then they can prepare for access, but the code must be changed periodically to prevent unauthorized use
Solution Approach 1:
The access code system transitions from static permanent codes to dynamic temporary codes with defined validity periods. Each temporary code is generated with specific expiration conditions (time-based or usage-based), automatically becoming invalid after the designated period without requiring manual changes by the user.
Solution Approach 2:
The system automatically manages the lifecycle of temporary access codes through the gateway, which generates, distributes, and tracks expiration of codes without requiring user intervention for code changes. The door lock system automatically validates whether a presented temporary code is still within its valid period.

AI summary
Provided is a method for controlling a door lock of a home network system, the method including: generating release information used for locking or unlocking the door lock in an external software module which communicates with a first smart terminal of a user according to a request from the first smart terminal, or in a software installed in the first smart terminal; transmitting the generated release information to the gateway and a second smart terminal of a temporary user; transmitting the received release information to a controller of the door lock; and locking/unlocking the door lock by determining whether release information input by the temporary user are identical to the release information transmitted from the gateway.
