Server Controlling Mobile Phone Information Sharing via GPS Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In social networking services, users face difficulties in manually finding and connecting with others sharing similar interests or backgrounds, leading to unwanted connections when automated grouping technologies fail to consider user preferences.
Innovation Solution
A server system that enables mobile devices to share information based on GPS location and user-defined preferences, allowing for controlled information sharing states between users, preventing unwanted connections by using a condition determining unit and restricting unit to assess and manage user connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated grouping technologies are used to connect users with similar interests, then connection efficiency is improved, but users may be connected with unwanted partners ignoring user preferences
Solution Approach 1:
The system performs preliminary actions by obtaining restriction information from users before automated connection decisions are made. The server stores and references user-defined restriction criteria (such as unwanted connection conditions) in advance, so that when automated grouping identifies potential connections, the system can pre-filter candidates against user preferences before presenting connection suggestions, thus preventing unwanted connections while maintaining efficiency
Solution Approach 2:
The system implements feedback mechanisms where user responses to connection suggestions are fed back into the system. When users accept or reject connection suggestions, this feedback is used to refine and update restriction information and connection criteria, improving the accuracy of future automated connections while continuing to respect user preferences
2Reliability
If manual methods are used to find partners with same interests, then connection accuracy is improved, but user time and effort increase
Solution Approach 1:
The server acts as an intermediary that performs the time-consuming task of filtering and matching users based on both their interests and restriction information. Instead of users manually searching through potential connections, the server automatically compares user profiles against stored restriction criteria and interest matching algorithms, presenting only suitable candidates to users, thus maintaining connection accuracy while significantly reducing user time and effort
Solution Approach 2:
The system enables self-service by allowing users to define their own connection criteria and restriction information once, which then automatically guides all future connection suggestions. Users don't need to repeatedly manually filter candidates; the system uses their predefined preferences to automatically identify and present compatible partners, maintaining accuracy while eliminating ongoing manual effort

AI summary
A server for controlling an information sharing state between a first mobile phone and a second mobile phone via a network, including: a network interface that communicates with the first mobile phone and the second mobile phone; a memory that stores a predetermined distance data; and circuitry that receives first and second GPS signals, first and second user information, and first and second restriction information from the first and second mobile phones respectively; calculates a distance between the first and second mobile phones; compares the distance with the predetermined distance; changes an information sharing state between the first and second mobile phones from a first state to a second state based on the comparison result; and restricts the change of the information sharing state based on the first restriction information and the second user information.
