Wi-Fi Direct Connection Control with Permitted Device Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Wi-Fi Direct communication, printing devices may inadvertently connect to unintended portable terminals during partner identification, leading to incorrect data transmission, requiring user confirmation which is labor-intensive.
Innovation Solution
A communication apparatus with an identification unit to determine permitted devices, a display unit for user confirmation, and a connection unit to execute wireless communication only with permitted devices or upon user instruction, preventing unintended connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic partner identification is used in Wi-Fi Direct communication, then connection speed and ease of operation are improved, but connection reliability deteriorates due to inadvertent connections to unintended devices
Solution Approach 1:
The patent implements a feedback mechanism where the identified communication partner's device information (device ID, device name, icon) is displayed to the user before final connection. The user can confirm or cancel the connection based on this feedback, ensuring connection reliability while maintaining ease of operation through automatic identification.
Solution Approach 2:
The patent performs preliminary display of communication partner information before establishing the connection. By showing device details in advance and allowing user confirmation, the system prevents inadvertent connections while maintaining the speed benefit of automatic partner identification.
2Reliability
If user confirmation is required for each connection, then connection reliability is improved, but ease of operation deteriorates due to increased user labor
Solution Approach 1:
The patent applies partial confirmation action by displaying communication partner information for user review before connection, but allowing automatic connection when the user confirms. This partial user involvement maintains reliability while minimizing labor compared to requiring continuous manual confirmation for all connection parameters.
Data Source
AI summary
When a communication partner of wireless communication is identified, a user is prompted to ascertain whether to execute wireless communication with the identified communication partner. When the user has given an instruction to execute wireless communication, connection processing of wireless communication with a communication apparatus identified as the communication partner is executed. Furthermore, if the identified communication partner is a permitted device, connection processing of wireless communication can be executed without requiring the user to confirm.
