Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication is used to transfer images from portable devices, then the need for memory cards and card slots is eliminated, but battery exhaustion during communication occurs
Solution Approach 1:
The print terminal performs preliminary actions by automatically detecting and identifying the portable device before wireless communication begins. The terminal reads device information, determines communication parameters, and prepares the communication channel in advance, so that when image transfer starts, the device is already optimized for energy-efficient communication.
Solution Approach 2:
The system enables self-service through automatic device identification and channel establishment. The print terminal autonomously detects the portable device, reads its identifying information, determines communication parameters, and sets up the wireless channel without user intervention, reducing the time the device's transmitter needs to operate and thus conserving battery power.
2Ease of operation
If automatic device identification is implemented, then user operation is simplified, but communication with wrong terminals may occur
Solution Approach 1:
The system implements feedback mechanisms where the print terminal reads identifying information from the portable device, compares it with stored or expected information, and confirms device identity before establishing communication. This feedback loop ensures that the correct device is identified and communicated with, preventing errors while maintaining automatic operation.
Solution Approach 2:
The patent uses an intermediary approach by introducing a non-contact IC card or similar identification medium as a mediator between the user and the wireless communication system. This intermediary carries identifying information that enables reliable device recognition and authentication, ensuring that communication occurs only with the intended device while simplifying the user's interaction to merely placing the device on the charging table.
3Adaptability or versatility
If multiple communication terminals are in the communication area, then wireless communication flexibility is improved, but the print terminal may communicate with wrong terminals
Solution Approach 1:
The non-contact IC card serves as an intermediary that simplifies the identification process. Instead of complex wireless protocols for device discovery and authentication, the system uses the IC card as a mediator that provides pre-stored identifying information, making the identification process simple and reliable even when multiple terminals are present.
Solution Approach 2:
The system uses copying by reading identifying information from the non-contact IC card rather than performing complex real-time device characterization. This information copying approach allows quick and accurate identification of the correct device among multiple candidates, reducing the complexity of terminal identification while maintaining wireless communication flexibility.
4Ease of operation
If connecting information is read from non-contact IC card, then connection establishment is simplified, but additional hardware components are required
Solution Approach 1:
The patent merges the IC card reader function with the existing charging table or device housing. The electromagnetic induction coil used for wireless charging also serves to power and communicate with the non-contact IC card, combining multiple functions into a single hardware component, thus simplifying the overall device structure while enabling simplified connection establishment.
Solution Approach 2:
The electromagnetic induction coil performs multiple functions: it provides wireless power transfer for charging the portable device and simultaneously enables communication with the non-contact IC card for device identification. This multi-functionality reduces the need for separate dedicated IC card reader hardware, minimizing device complexity while maintaining ease of connection establishment.

AI summary
As the present invention is adapted to receive an image to be printed or to be saved from a portable device having the image by wireless communication, an image needs not to be passed via a memory card or by connector connection or the like. As the present invention is also adapted to automatically identify the other party's device to wirelessly communicate with and establish a channel, and further adapted to supply power to the other party's device without contact, it is advantageous that a battery of the portable device is not exhausted or the portable device is not disconnected even if the device communicates wirelessly for a long time.
