Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If NFC card emulation function is used to notify communication terminal of IDs, then the image forming apparatus can provide basic identification information, but the communication terminal cannot execute the appropriate application corresponding to the state of the image forming apparatus
Solution Approach 1:
The patent segments information transmission into two distinct phases: first using NFC for basic identification (ID notification), then using wireless LAN for detailed application information transmission. This segmentation allows each communication method to be optimized for its specific purpose, resolving the contradiction between providing sufficient information and ensuring proper application execution.
Solution Approach 2:
The patent introduces a wireless LAN communication portion as an intermediary between the NFC card emulation function and the application execution. The NFC function triggers the wireless LAN communication, which then transmits the detailed application information needed for correct application execution, acting as a mediator that bridges the gap between basic identification and comprehensive information delivery.
2Speed
If only NFC communication is used, then the communication is simple and fast for basic ID notification, but the image forming apparatus cannot transmit detailed application information corresponding to its state
Solution Approach 1:
The patent divides the communication process into two segments: NFC for fast initial connection and ID notification, then wireless LAN for detailed application information transmission. This segmentation maintains the speed advantage of NFC for basic communication while adding the capability to transmit comprehensive information through wireless LAN.
Solution Approach 2:
The NFC card emulation function performs a preliminary action by notifying the communication terminal of the image forming apparatus ID first. This preliminary notification triggers the subsequent wireless LAN communication that transmits the detailed application information, preparing the communication terminal for the more comprehensive data exchange.
3Adaptability or versatility
If wireless LAN communication is used for detailed application information, then the communication terminal can execute the appropriate application, but the initial connection and identification process becomes more complex
Solution Approach 1:
The patent inverts the traditional communication sequence by using NFC first for simple ID notification, then invoking wireless LAN for detailed information. This inversion simplifies the initial connection process while still enabling comprehensive information delivery, as the NFC portion handles the complex task of triggering the appropriate communication protocol based on the apparatus state.
Solution Approach 2:
The image forming apparatus automatically determines its state and selects the appropriate application information to transmit without requiring manual configuration. The system self-services by using the NFC card emulation function to initiate the communication process and the wireless LAN portion to automatically transmit the correct application information based on the stored state data.
Data Source
AI summary
A storage portion stores information, which can be obtained from an image forming apparatus by a communication terminal, as a result of wireless communication with the communication terminal via a first communication portion. The processor stores setting information, the information set in the communication terminal to perform communication with the communication terminal via a second communication portion, in the storage portion. The processor stores application information, the information that can identify an application which is executed by the communication terminal in accordance with a state of the image forming apparatus, in the storage portion. The processor receives the data transmitted from the communication terminal in accordance with the application being executed in the communication terminal as a result of wireless communication, via the second communication portion, with the communication terminal in which the setting information stored in the storage portion by the first storing is set.
