Solution Overview
Problem
Existing image capturing apparatuses that operate as access points face complexity in setting function limitations for external devices, requiring pre-acquisition of device identifier information for each device, leading to a cumbersome operation for users.
Innovation Solution
A communication apparatus capable of generating multiple wireless networks, with a determination unit to identify the connected network and a control unit to dynamically change available functions based on the network, allowing easy management of function provision to external devices without prior settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If device identifier information is acquired in advance and functions are preliminarily set for each device, then function provision can be controlled for each external device, but the operation becomes complicated and cumbersome
Solution Approach 1:
The patent divides the single wireless network into multiple virtual access points (first AP and second AP), each with independent function settings. This segmentation allows different function sets to be assigned to different networks, eliminating the need for complex per-device configuration while maintaining reliable function control based on which network the device connects to.
Solution Approach 2:
The patent introduces virtual access points as intermediaries between the image capturing apparatus and external devices. These APs act as mediators that automatically determine function provision based on the network connection, replacing the need for direct device identifier-based configuration and simplifying user operation.
2Adaptability or versatility
If multiple functions are provided to external devices, then device versatility is improved, but security risk increases as owners may not want to provide editing and deletion functions to other users' devices
Solution Approach 1:
The patent segments the function provision into different groups by creating multiple virtual access points. The first AP provides comprehensive functions including editing and deletion, while the second AP provides limited functions. This segmentation allows high versatility for authorized devices connected to the first AP while maintaining security by restricting access to sensitive functions for devices connected to the second AP.
Solution Approach 2:
The patent applies different function quality levels to different virtual access points. The first AP has high-quality comprehensive function access, while the second AP has limited function access. This local quality differentiation enables tailored function provision based on connection type, balancing versatility and security.
3Device complexity
If a single wireless network is used, then device complexity is reduced, but the ability to provide different functions to different devices is limited
Solution Approach 1:
The patent makes the single image capturing apparatus multi-functional by enabling it to operate as multiple virtual access points simultaneously. This multi-functionality allows the device to provide different function sets through different APs, achieving adaptability and versatility without requiring multiple physical devices or complex network infrastructure.
Solution Approach 2:
The patent adds a virtual dimension to the network structure by implementing multiple virtual access points within a single physical device. This dimensional change from physical multiplicity to virtual multiplicity enables function differentiation while maintaining physical simplicity and low device complexity.

AI summary
A communication apparatus generates a first wireless communication network and transmits/receives information via the first wireless communication network. The communication apparatus generates a second wireless communication network different from the first access point and transmits/receives information via the second wireless communication network. The communication apparatus controls to change a function available by using a predetermined application in accordance with the first or second wireless network via which an external device establishing communication is connected.
