Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth pairing is used for wireless communication between mobile phone and image forming apparatus, then wireless data transmission is enabled, but complicated setup procedures are required
Solution Approach 1:
The patent introduces an intermediary device (e.g., smartphone with NFC) that facilitates the pairing process between the mobile phone and image forming apparatus. The intermediary captures images of the apparatus, extracts identification information, and automatically completes the Bluetooth pairing without requiring manual setup procedures from the user.
2Productivity
If manual memory card insertion is used to print data, then data transmission is achieved, but troublesome procedures and time consumption occur
Solution Approach 1:
The patent replaces the mechanical system of physically inserting and removing memory cards with an automated wireless communication system. The system uses optical recognition and automatic Bluetooth pairing to establish data transmission, eliminating the need for manual memory card handling and significantly reducing the time required for the printing process.
3Measurement precision
If Bluetooth address distinction is required among multiple apparatuses, then correct device identification is possible, but the distinction process becomes very difficult
Solution Approach 1:
The patent uses image capture and processing to create a visual representation of the image forming apparatus. The system captures an image of the apparatus display, extracts the Bluetooth address and other identification information from the image, and presents it to the user in a recognizable format, making device identification intuitive and eliminating the difficulty of manually distinguishing between multiple Bluetooth addresses.

AI summary
An image forming apparatus includes a first wireless communication unit that receives data from a mobile phone, and a reader-writer that transmits an address of the first wireless communication unit to the mobile phone. The mobile phone includes a contact/non-contact IC card that receives the address, and a second wireless communication unit that transmits image data to the first wireless communication unit utilizing the address. When communication is made between the mobile phone and the image forming apparatus, the address of the first wireless communication unit is transmitted to the contact/non-contact IC card through the reader-writer, and the second wireless communication unit transmits data to the first wireless communication unit utilizing the address.
