Information Sharing System Conflict Prevention via Dynamic Editing Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic conferences, simultaneous remote operations from multiple users on the same information can lead to conflicts, making it difficult to determine the newest information and preventing appropriate sharing, especially when the first user to edit is granted exclusive rights, hindering the transmitting person or administrator's ability to modify the displayed information.
Innovation Solution
An information sharing system where a common terminal receives objects from personal terminals, displays them, and controls remote operations by determining if instructions satisfy predetermined conditions, prohibiting operations that do not meet these conditions, and limiting editing rights to the transmitting person or administrator initially, then allowing other users after a specified time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first user to edit is granted exclusive rights, then operation conflicts are prevented, but the transmitting person or administrator loses the ability to modify displayed information
Solution Approach 1:
The patent implements dynamic editing rights that change over time. Initially, only the transmitting person can edit the object. After a predetermined time period, the editing rights are dynamically transferred to other users. This temporal dynamic resolves the contradiction by allowing the transmitting person to edit initially (maintaining ease of operation) while preventing conflicts later when other users can edit (maintaining reliability).
Solution Approach 2:
The system performs preliminary action by establishing the transmitting person as the exclusive editor before any other user attempts to edit. This preliminary designation of editing rights prevents operation conflicts from the outset, while the predetermined time mechanism ensures that editing rights will later be transferred, preserving the transmitting person's initial ability to modify information.
2Adaptability or versatility
If simultaneous remote operations are allowed, then information sharing freedom is maintained, but operation conflicts occur making it difficult to determine newest information
Solution Approach 1:
The patent implements periodic action by dividing the editing permission into time periods. During the first period (predetermined time after transmission), only the transmitting person can edit. During subsequent periods, other users can edit. This periodic structure maintains information consistency within each period while allowing editing freedom across different periods, resolving the contradiction between operation freedom and information consistency.
Solution Approach 2:
The system dynamically adjusts who can perform remote operations based on the elapsed time since object transmission. The editing rights are not static but change from exclusive control by the transmitting person to shared control among users. This dynamic approach maintains reliability during the initial period while providing adaptability and freedom in later periods.
3Reliability
If editing rights are restricted to maintain information integrity, then operation conflicts are prevented, but other users cannot contribute to modifying information
Solution Approach 1:
The patent uses periodic action to grant editing rights in stages. Initially, editing rights are restricted to the transmitting person to maintain information integrity. After the predetermined time period expires, editing rights are periodically updated to include other users, enabling them to contribute. This resolves the contradiction by ensuring integrity during the initial period while enabling user contribution in subsequent periods.
Solution Approach 2:
The system performs preliminary action by first establishing restricted editing rights to protect information integrity. After this preliminary phase completes (after predetermined time), the system then enables broader user contribution. This staged approach ensures that information integrity is maintained during the critical initial phase while user adaptability and contribution ability are activated later.

AI summary
There are provided an information sharing system, a common terminal and a non-transitory computer-readable storage medium storing an information sharing program. An information sharing system includes: a common terminal; and one or more personal terminals each configured to transmit an object to the common terminal and perform a remote operation on an object displayed on a common screen. The common terminal includes a receiving section configured to receive an object transmitted from one of the personal terminals, a display section including the common screen and being configured to display the object on the common screen, and a control section configured to determine, upon receiving an instruction to perform a remote operation on an object displayed on the common screen, whether the instruction satisfies a predetermined condition or not, and prohibit performing the remote operation in response to a determination that the instruction does not satisfy the predetermined condition.
