Short-Range Wireless Communication Apparatus Registration Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing NFC-based short-range wireless communication systems face inconvenience in managing registered mobile terminals, leading to unnecessary time-outs and cumbersome operations when trying to share data, as they fail to distinguish between currently used and non-used terminals, resulting in an increased number of registered devices and inefficient data sharing.
Innovation Solution
A short-range wireless communication apparatus and registration management program that utilize a contactless communicator, a short-range wireless communicator, and a power detector to establish and maintain connections, search for registered mobile terminals upon power state changes, and unregister unsuccessful searches, thereby simplifying the selection and management of active devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If guests' mobile terminals are continuously registered to the short-range wireless communication apparatus, then the number of registered terminals increases, but the list becomes inconvenient for both guests to select their own terminal and hosts to unregister unused terminals
Solution Approach 1:
The system performs preliminary actions by detecting power state changes and automatically searching for registered mobile terminals when the apparatus is powered on. This proactive approach identifies which terminals are currently in use before the user needs to select them, eliminating the need for manual searching through long registration lists.
Solution Approach 2:
The system provides self-service functionality by automatically managing the registration list through power state detection and terminal searching. The apparatus autonomously determines which terminals are currently used without requiring host intervention to manually add or remove terminals, thereby maintaining an up-to-date registration list.
2Adaptability or versatility
If the system automatically tries to connect to all registered mobile terminals, then data sharing capability is maintained, but useless time-out occurs until it is determined that the targeted terminal belongs to a guest not currently using the apparatus
Solution Approach 1:
The system performs preliminary searching for registered mobile terminals immediately upon power-on detection, before attempting data sharing connections. This advance identification of currently used terminals prevents unnecessary connection attempts to inactive terminals, thereby eliminating time-out delays while preserving the ability to share data with all relevant terminals.
3Reliability
If mobile terminals are registered using NFC communication, then security and identification are ensured, but the mobile terminal must be positioned over the apparatus each time the permitted terminal is changed
Solution Approach 1:
The system performs preliminary searching for registered mobile terminals automatically when powered on, before requiring any NFC positioning operations. This advance identification maintains security through existing NFC registrations while eliminating the need for repeated positioning operations when changing active terminals, as the system proactively determines which terminal is currently in use.
Solution Approach 2:
The system provides self-service by automatically managing terminal identification through power state detection and searching, reducing the need for manual NFC positioning operations. The apparatus autonomously determines which registered terminal is currently used without requiring the user to repeatedly position their device over the apparatus for identification.

AI summary
A short-range wireless communication apparatus includes a contactless communicator, a short-range wireless communicator, a power detector for detecting a power-on state and a power-off state, and a controller for registering the mobile terminal establishing contactless communication upon determining that the contactless communication is established between the mobile terminal and the contactless communicator, and for permitting connection of the short-range wireless communication between the short-range wireless communicator and the mobile terminal until determining that the short-range wireless communication becomes unconnectable. When the power detector detects that the power-on state is changed to the power-off state and the power-off state is then changed to the power-on state, the controller causes the short-range wireless communicator to search for the registered mobile terminal. When the search is unsuccessful, the controller unregisters the mobile terminal for which the search is unsuccessful.
