Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is uploaded from communication apparatus to server via portable terminal using portable telephone communication, then communication can be maintained, but upload speed is restricted and transmission efficiency deteriorates
Solution Approach 1:
The patent divides the communication path into two separate communication interfaces: wireless LAN interface for high-speed data reception from communication apparatus, and portable telephone interface for maintaining connection with server. This segmentation allows each interface to operate at its optimal speed without being constrained by the slower interface.
Solution Approach 2:
The portable terminal acts as an intermediary device between the communication apparatus and the server. It receives data via wireless LAN and forwards it to the server via portable telephone network, mediating the transfer between different communication systems to achieve both high-speed reception and maintained connectivity.
2Loss of time
If portable terminal uses single communication interface for both receiving and uploading data, then device complexity is reduced, but waiting time increases and operational efficiency deteriorates
Solution Approach 1:
The patent enables continuous data transfer by establishing parallel communication channels. While data is being received via wireless LAN, the terminal simultaneously maintains server connection via portable telephone interface, ensuring continuous upload capability without waiting for interface switching or connection establishment.
Solution Approach 2:
The system dynamically utilizes multiple communication interfaces based on their respective strengths. The wireless LAN interface is optimized for high-speed data intake while the portable telephone interface handles server communication, creating a dynamic architecture that adapts to different communication requirements and eliminates idle waiting time.
3Ease of operation
If portable terminal processes data sequentially through single interface, then device complexity is reduced, but process heaviness increases and smooth operation deteriorates
Solution Approach 1:
The patent changes the operational parameters by utilizing multiple communication interfaces simultaneously with different characteristics. By adjusting which interface handles which communication task (wireless LAN for reception, portable telephone for upload), the system optimizes performance parameters while maintaining manageable complexity through clear interface assignment.

AI summary
In order to solve the problem of performing data transmission between a server and a communication apparatus via a portable terminal apparatus at a high speed, the portable terminal apparatus is provided with: a first communication means which connects with a server on a network and communicates data, a second communication means which connects with the communication apparatus and performs data communication, a temporary storage means which temporarily stores data when relaying data communication between the server and the communication apparatus using the first communication means and the second communication means, and a control means which can control data communication performed by the first communication means and the second communication means asynchronously and in parallel when relaying data communication between the server and the communication apparatus.
