Communication Interface State Management for Stable Access Point Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers continuously update access point information during tag communication, leading to unnecessary changes in stored access point information, which can be problematic when the information should remain unchanged.
Innovation Solution
A communication apparatus with multiple operating states for its interfaces, allowing specific access point information to be registered only when received from a terminal device in a specific state, preventing unnecessary registration and maintaining stable access point information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printer receives access point information from the operation terminal each time a tag communication is performed, then the access point information can be updated to reflect current network settings, but the access point information changes unnecessarily and can change even when it should remain stable
Solution Approach 1:
The patent applies dynamics by introducing multiple operating states (first operating state and second operating state) for the first interface. The interface dynamically switches between these states based on connection status with terminal devices. In the first operating state, access point information is received and registered; in the second operating state, information reception is suppressed. This dynamic state management allows the system to adapt to different operational contexts while maintaining stability when needed.
Solution Approach 2:
The patent implements feedback by having the apparatus controller monitor the operating state of the first interface and use this feedback to control whether access point information should be received and registered. The controller receives feedback about the connection status between terminal devices and adjusts the information reception behavior accordingly, preventing unnecessary updates when the printer is already connected to an access point.
2Adaptability or versatility
If the printer continuously updates access point information during tag communication, then network adaptability is improved, but unnecessary registration occurs and system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the operating states into distinct first and second operating states, each with specific behaviors regarding access point information reception. This segmentation simplifies the control logic by creating clear, discrete states rather than continuous or ambiguous operational modes, making the state management more manageable despite the added complexity of multi-state operation.

AI summary
A communication apparatus may include: a first interface being set in one of a first operating state and a second operating state; a second interface; and an apparatus controller. The first interface is configured to: receive specific access point information in a case where a wireless connection is established in a situation where the first interface is set in the first operating state; and not receive the specific access point information in a case where a wireless connection via the first interface is established in a situation where the first interface is set in the second operating state. The apparatus controller performs: setting the first interface in the first operating state in a case where the access point information is not registered; registering the specific access point information; and setting the first interface in the second operating state in a case where the specific access point information is registered.
