Terminal Apparatus Wireless Scan Scheme Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telephone systems with wireless telephones and control apparatuses face challenges in efficiently executing scan functions and selecting appropriate communication schemes for sending scan data, particularly in multi-function peripherals (MFPs) that need to communicate with portable terminals using various wireless protocols.
Innovation Solution
A terminal apparatus and function executing apparatus are designed to receive instructions, select appropriate communication schemes from available options (such as normal Wi-Fi, WFD, and BT), and send scan data accordingly, utilizing a processor and memory with computer-readable instructions to manage communication protocols and settings for different wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication schemes are supported for scan data transmission, then adaptability and versatility are improved, but device complexity increases
Solution Approach 1:
The terminal apparatus automatically determines the appropriate communication scheme by itself based on whether the function executing apparatus is within wireless LAN coverage, without requiring manual configuration or complex negotiation protocols. The system self-selects between Wi-Fi and Bluetooth based on the detected coverage status, simplifying the overall system complexity while maintaining multi-scheme support
Solution Approach 2:
The communication scheme selection is dynamic rather than static - the terminal apparatus can switch between Wi-Fi and Bluetooth schemes based on real-time coverage conditions. This dynamic adaptation allows the system to respond to changing environmental conditions without requiring complex pre-configuration
2Ease of operation
If automatic communication scheme selection is implemented, then ease of operation is improved, but processing time and complexity increase
Solution Approach 1:
The terminal apparatus performs preliminary detection of wireless LAN coverage status before initiating scan data transmission. By determining the coverage status in advance and selecting the appropriate communication scheme beforehand, the system avoids time-consuming negotiations or trial-and-error approaches during actual data transfer
Solution Approach 2:
The communication process is segmented into distinct phases: coverage detection phase, scheme selection phase, and data transmission phase. This segmentation allows each phase to be optimized independently, with the coverage detection and scheme selection completed efficiently before the main data transmission begins

AI summary
A terminal apparatus may receive first information relating to a first function executing apparatus from the first function executing apparatus. The first function executing apparatus may be configured to execute a scan function. The terminal apparatus may select, by using the first information, a particular communication scheme from among M1 items of communication schemes in a case where the first information is received. Each of the M1 items of communication schemes may be different from each other and may be a communication scheme available for the first function executing apparatus to send scan data. The terminal apparatus may send a first selection result indicating the particular communication scheme to the first function executing apparatus in a case where the particular communication scheme is selected from among the M1 items of communication schemes.
