Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless communication is used to connect image processing apparatus with external apparatus, then installation simplicity is improved, but communication compatibility and reliability deteriorate due to differences in communication standards and channel occupancy
Solution Approach 1:
The wireless communication function is segmented into multiple independent communication channels (first wireless communication channel and second wireless communication channel). Each channel can operate independently with different communication standards, allowing the system to maintain compatibility while improving reliability through channel diversity.
Solution Approach 2:
The image processing apparatus is designed with multi-functional communication capabilities, incorporating both a first access point module for relay communication and a second client module for direct communication. This universal design enables the apparatus to adapt to different communication standards and network configurations, resolving compatibility issues while maintaining installation simplicity.
2Device complexity
If single wireless communication channel is used, then device complexity is reduced, but communication efficiency and quality deteriorate due to channel traffic occupancy
Solution Approach 1:
The communication function is divided into multiple channels with different roles: the first wireless communication channel handles relay communication through the access point module, while the second wireless communication channel handles direct client communication. This segmentation allows traffic to be distributed across multiple channels, improving communication efficiency without significantly increasing device complexity.
Solution Approach 2:
The controller acts as an intermediary that manages communication data routing between different channels. It selectively switches communication data between the first and second wireless communication channels based on communication addresses, optimizing transmission paths and reducing channel traffic occupancy while maintaining manageable system complexity.
3Ease of operation
If communication data is transmitted through fixed channel, then control simplicity is maintained, but communication quality and stability deteriorate due to channel traffic congestion
Solution Approach 1:
The communication channel selection is made dynamic rather than fixed. The controller automatically determines which channel to use for transmitting communication data based on the extracted communication address and current channel conditions. This dynamic channel switching improves communication quality and stability while maintaining operational simplicity through automated control.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller extracts communication addresses from received data and uses this information to determine the optimal transmission channel. This feedback loop ensures that communication data is routed through the most appropriate channel, improving communication quality while keeping the control logic simple and rule-based.

AI summary
An image processing apparatus for performing wired and wireless communication includes: an image processing unit; a first access point module which communicates with an external apparatus through a first wireless communication channel and relays a communication between a plurality of external apparatuses through the first wireless communication channel; a client module which communicates with a second external access point module through a second wireless communication channel different from the first wireless communication channel; and a controller which switches communication data received through the first wireless communication channel or the second wireless communication channel to be selectively transmitted through one of the first wireless communication channel or the second wireless communication channel.
