Solution Overview

Problem

Ad-hoc Social Network Service (ASNS) community sites face challenges with unmanaged sites after real-world events, leading to security concerns and reduced user engagement due to the lack of a manager, and potential unauthorized access to information.

Innovation Solution

An apparatus and method for managing community sites using terminal data from mobile devices, including a communication unit, memory, and processing unit to permit access, store content, and delete content based on predetermined conditions, ensuring site security and user peace of mind.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manager is appointed to manage the community site, then the community site can be properly managed and secured, but the complexity of the system increases and requires additional human resources

Engineering Contradiction:
Improvecommunity site management reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically determines whether a community site should be deleted by evaluating predetermined conditions (such as event completion status, time elapsed, and activity level) without requiring manual intervention from a manager. The server autonomously performs the deletion decision and execution, making the system self-managing and eliminating the need for dedicated human managers while maintaining reliability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-defines deletion conditions and criteria before the community site becomes unmanaged. By establishing predetermined conditions for deletion in advance (such as time-based expiration, event completion triggers, or inactivity thresholds), the system prepares the deletion mechanism beforehand, ensuring automatic and consistent management decisions without requiring real-time human judgment

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the community site is left unmanaged after the event, then the system remains simple and easy to operate, but security risks increase and unauthorized access may occur

Engineering Contradiction:
Improvesystem operation simplicityVSAvoidsecurity risks
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The server automatically monitors and evaluates whether predetermined deletion conditions are met, then autonomously deletes the community site and its content without requiring user action. This self-service mechanism maintains system simplicity while eliminating security risks by ensuring timely deletion of unmanaged sites

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors the state of the community site and related conditions (event status, time elapsed, user activity) and uses this feedback to automatically determine when deletion should occur. This feedback loop ensures the system responds appropriately to changing conditions while maintaining operational simplicity

Inventive Principle:
Principle #23Feedback

3Reliability

If content is automatically deleted based on predetermined conditions, then security and user peace of mind are improved, but the risk of deleting important content before intended increases

Engineering Contradiction:
Improveinformation securityVSAvoidpotential content loss
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system pre-defines clear deletion conditions (such as event completion, time expiration, or inactivity thresholds) before content is deleted. By establishing these conditions in advance and making them transparent, the system ensures that deletion only occurs when predetermined criteria are met, preventing premature or unintended deletion while maintaining security

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system can implement a deletion buffer period or confirmation mechanism before final deletion occurs. This cushioning approach allows for a grace period where content can be recovered or conditions re-evaluated, providing protection against accidental deletion while still enabling automatic deletion when conditions are clearly met

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Methods and apparatus of managing a community site. Upon execution of processor-executable instructions by a processing unit, the processing unit manages the community site in accordance with management data so as to permit access to the community site by a plurality of terminal apparatuses based at least in part on terminal data from each of the plurality of terminal apparatuses. The terminal data indicates at least one of a time or a location associated with the terminal apparatus. The processing unit further stores content uploaded from at least one of the plurality of terminal apparatuses to at least one storage device, the content being accessible via the community site. In response to at least one predetermined condition relating to the usage of the community site being satisfied, the processing unit sends a signal to delete the content from the at least one storage device.
