Communication Apparatus Selective Access Point Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers frequently update access point information during tag communication, leading to unnecessary changes in stored access point information, which can be undesirable in certain situations.
Innovation Solution
A communication apparatus with dual interfaces (Wi-Fi and NFC) and a controller that selectively registers and maintains access point information, preventing registration of new information when not required, by distinguishing between different terminal devices and communication states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printer receives access point information from operation terminal each time tag communication is performed, then the access point information can be updated, but the access point information in the memory changes even in situations where it should not change
Solution Approach 1:
The patent changes the parameter of information registration by introducing a determination step that checks whether access point information should be registered before actually registering it. The controller determines based on reception history whether to register the access point information, thereby controlling the registration parameter dynamically to prevent unnecessary updates while allowing needed updates.
2Loss of information
If the printer stores new access point information from operation terminal, then the latest access point information is maintained, but unnecessary changes occur leading to connectivity issues
Solution Approach 1:
The patent implements feedback by having the controller check reception history to determine whether access point information has been received from the same operation terminal before. This feedback mechanism prevents unnecessary updates by recognizing repeated transmissions from the same terminal, thereby avoiding harmful changes while retaining necessary information updates.
3Ease of operation
If the printer performs tag communication with operation terminal, then access point information can be transmitted, but the information changes even when the printer should maintain existing connection
Solution Approach 1:
The patent applies preliminary action by performing a determination check before registering access point information. The controller预先 checks whether the access point information should be registered by examining reception history, and only proceeds with registration if appropriate. This preliminary determination prevents unnecessary changes while maintaining the ease of wireless information transmission.

AI summary
A communication apparatus may include: a first interface; a second interface; an apparatus memory; and an apparatus controller. The apparatus controller performs: in a case where the first interface receives from a first terminal device a first type of signal related to sending of the access point information to the communication apparatus in a state where the access point information is not registered, registering first access point information, the first access point information being received by the first interface from the first terminal device; and in a case where the first interface receives the first type of signal from a second terminal device after the first access point information has been registered, maintaining the registration of the first access point information that has been registered, without registering second access point information, which is registered in the second terminal device, instead of the first access point information.
