Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies lack the ability for instant modification of projection files during a presentation, leading to low efficiency in collaborative learning and discussion among participants.
Innovation Solution
A method and system that connects a router terminal with a projector device, establishes a projection local area network, and enables data synchronization between collaborative terminals to allow real-time modification and updating of projection files, controlling access rights to facilitate instant changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional projection mode is used where files are loaded into projector by projection worker, then device complexity is reduced, but productivity and ease of operation deteriorate due to manual file copying and gathering operations
Solution Approach 1:
The patent merges multiple terminals (mobile phones, tablets, computers) into a unified projection network system through a router, enabling collaborative file modification. Multiple terminals are combined into one networked system where files can be synchronized and modified by any participant, resolving the contradiction by automating file management operations.
Solution Approach 2:
The router acts as an intermediary device that mediates between the projector and multiple collaborative terminals. It manages file synchronization, controls access rights, and coordinates data flow between terminals and the projector, enabling efficient collaborative operation without requiring complex peer-to-peer negotiations between all devices.
2Ease of operation
If projection file modification is enabled during presentation, then ease of operation improves, but reliability deteriorates due to potential data synchronization conflicts between multiple terminals
Solution Approach 1:
The system implements feedback mechanisms where the router continuously monitors file modification status across all terminals and the projector. When a file is being projected, the router receives feedback about the current synchronization state and actively manages access rights to prevent conflicts, ensuring data consistency while allowing real-time modifications.
Solution Approach 2:
The system dynamically adjusts access rights and synchronization modes based on the current projection state. During active projection, the router controls which terminals can modify files and manages the transition of file ownership dynamically, allowing real-time modifications while maintaining data reliability through adaptive access control.
3Adaptability or versatility
If multiple terminals can simultaneously access projection files, then adaptability improves, but loss of time increases due to file copying and gathering operations before projection
Solution Approach 1:
The system performs preliminary actions by pre-establishing the projection network and pre-synchronizing files to the router before the projection session begins. All terminals connect to the router in advance, and files are pre-loaded into the router's storage, so that during the actual projection, no additional file copying or gathering is needed, eliminating preparation time losses.
Data Source
AI summary
The disclosure discloses a method and a system for implementing projection. The method comprises: connecting a router terminal having a file storage function with a projector device, establishing a projection local area network via the router terminal, and adding all collaborative terminals to the projection local area network; during projecting, establishing data synchronization between a first collaborative terminal that sends a projection file and the router terminal, and meanwhile controlling, by the router terminal, the access right of other collaborative terminals in the projection local area network on the projection file; when a second collaborative terminal needs to modify the content of the projection file, the router terminal stopping the data synchronization with the first collaborative terminal, and establishing data synchronization with the second collaborative terminal and meanwhile granting the access right of the projection file to the second collaborative terminal, so as to modify and project the projection file.
