Server device and door control device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door unlock systems require user permission for unlocking, which is not feasible when the user is absent, hindering package delivery or retrieval in multifamily residential settings.
Innovation Solution
A server device and door control device system that allows service providers to unlock doors without user permission by using a service number, such as a package tracking number, and includes authentication and notification mechanisms to ensure secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user permission is required for door unlocking, then security is improved, but service providers cannot deliver packages when users are absent
Solution Approach 1:
The patent introduces a server as an intermediary between the door control device and service providers. The server stores service numbers and performs authentication, mediating the access control process to enable service providers to unlock doors without direct user permission while maintaining security through centralized authentication.
Solution Approach 2:
The system performs preliminary authentication by storing service numbers in advance in the server. When a service provider needs to deliver a package, the pre-stored service number is used for authentication, eliminating the need for real-time user permission and enabling delivery even when users are absent.
2Reliability
If advance permission is required at purchase time, then access control is secured, but the system cannot be used for third-party package delivery
Solution Approach 1:
The server-based authentication system provides universal access control that serves multiple functions: it maintains security for registered users while also enabling third-party service providers to access the premises using service numbers. This multi-functional approach allows the same system to handle both user permission and service provider authentication.
Solution Approach 2:
The server acts as a mediator that decouples the authentication process from direct user involvement. Service providers can obtain service numbers and use them for authentication without needing advance permission from users, enabling third-party package delivery while maintaining access control security.
3Productivity
If service providers can unlock without user permission, then package delivery efficiency is improved, but authentication complexity increases
Solution Approach 1:
The patent extracts the authentication logic from the door control device and places it in a separate server. The door control device only needs to communicate unlock requests and receive instructions, while the complex authentication process using service numbers is handled by the server, reducing device complexity while enabling efficient package delivery.
Solution Approach 2:
The server serves as an intermediary that handles the complex authentication process using service numbers. This centralizes the complexity in one location while keeping the door control device simple, thereby improving package delivery efficiency without making the overall authentication system overly complex at the access point.

AI summary
It A service provider such as a courier to unlock a door without a permission of a user. A server device, which is capable of communicating with a door control device that controls locking and unlocking of a door installed at an entrance of a multifamily residential, includes: a storage that stores, for each user, a service number set by a service provider; a request reception that receives, from the door control device, an unlock request including a device ID and the service number; an authentication that executes an authentication based on information included in the unlock request and information stored in the storage; and unlock instructions that transmits an unlock instruction to the door control device, when the authentication is succeeded.
