Server-Mediated Data Exchange for Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems fail to enable communication between users whose devices have exchanged data when they are no longer within the wireless communication range, limiting interaction after initial data exchange.
Innovation Solution
A system comprising information processing devices with wireless communication functions and a server, where devices obtain and transmit identification information, allowing data exchange and communication through the server even after devices are out of range, using first and second identification information for accessing and publishing user data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices exchange data only when located within wireless communication range, then data exchange is simple and direct, but communication cannot continue after devices are separated by distance exceeding the wireless communication range
Solution Approach 1:
The patent introduces a server as an intermediary component that stores transmission data received from one device and forwards it to another device after they have passed each other. This mediator enables communication continuity beyond direct wireless range, resolving the contradiction between maintaining simple device-to-device exchange and ensuring communication reliability after separation.
2Ease of operation
If devices maintain constant wireless connection for communication, then communication is immediate, but energy consumption increases and operation becomes complex when devices are mobile
Solution Approach 1:
The patent implements preliminary action by having devices transmit their identification information and store transmission data on a server before the actual communication need arises. When devices pass each other, they exchange identification information in advance, and the server prepares the transmission data for later delivery, eliminating the need for constant connection maintenance and reducing energy consumption while mobile devices move.

AI summary
Web pages corresponding to example game devices are previously provided in a server. One of the game devices obtains a character from another one of the game devices when these game devices pass each other. The one of the game devices processes the obtained character and transmits the processed character to the web page corresponding to the other game device in the server, and the character is stored in the server. The other game device accesses the web page corresponding to the other game device in the server to obtain the processed character.
