Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple membership cards and physical keys are used for different services, then access control reliability is improved, but device complexity and ease of operation deteriorate due to needing to manage multiple items
Solution Approach 1:
The patent combines multiple access control functions into a single mobile terminal device. The mobile terminal stores multiple network addresses and can selectively connect to different gates or doors, replacing the need for multiple physical cards or keys. This merging approach maintains access control reliability while reducing the number of items users need to manage.
Solution Approach 2:
The mobile terminal is designed to perform multiple access control functions universally. It can store network addresses for multiple gates and doors, and the server can authenticate the mobile terminal for different locations. This multi-functionality allows a single device to replace multiple specialized access items.
2Adaptability or versatility
If multiple application software are installed for different services, then service functionality is improved, but ease of operation deteriorates due to needing to start different applications
Solution Approach 1:
The mobile terminal serves as a universal access control client, replacing the need for multiple service-specific applications. The terminal communicates with a centralized server that handles authentication for different gates and doors. This approach maintains diverse service functionality while simplifying user interaction to a single device operation.
Solution Approach 2:
The server acts as an intermediary between the mobile terminal and multiple access control systems. Instead of requiring the terminal to have multiple applications for different services, the server mediates authentication requests, allowing the terminal to access different gates and doors through a unified interface.
3Reliability
If physical keys and cards are used for door unlocking, then access security is improved, but loss of substance occurs due to physical items being lost or stolen
Solution Approach 1:
The patent replaces mechanical access items (physical keys and cards) with an electronic system based on network communication. The mobile terminal uses its network address to authenticate with the server, which then controls the gates and doors. This substitution eliminates the risk of physical items being lost or stolen while maintaining access security through digital authentication.

AI summary
A gate opening method includes: a step (S8) of transmitting a gate opening signal for making a request for opening of a gate, which is configured to restrict entry into a predetermined space, to the gate by using an IP address unique to a mobile terminal associated with a user; a step (S9) of determining whether or not to allow the user to enter the predetermined space based on a ticket management table and the IP address of the mobile terminal in response to reception of the gate opening signal; and a step (S11) of controlling the gate so that the user is able to enter the predetermined space in response to a determination that the user is allowed to enter the predetermined space. The ticket management table includes a plurality of pieces of network address information indicating a plurality of IP addresses unique to a plurality of mobile terminals.
