Projector Group Connection via Automatic ID Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems face delays in establishing connections between multiple projectors and computers due to the need for each computer to search and register multiple projectors, making concurrent image projection inefficient.
Innovation Solution
A projector system and method where each projector acquires group information including apparatus IDs and requests connections with other projectors within the group upon receiving a connection request from a computer, allowing any computer to connect to all projectors in a group by connecting to one arbitrary projector, and enabling automatic addition or removal of projectors while maintaining group connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each computer searches and registers multiple projectors to establish connection, then connection can be established between computer and projectors, but connection establishment time increases
Solution Approach 1:
Projectors perform preliminary actions by acquiring group information containing apparatus IDs of all projectors in the group and storing it in advance. When a computer sends a connection request to any projector, the stored group information is immediately used to establish connections with all projectors without requiring each computer to search and register individually, thus reducing connection establishment time while ensuring reliable connection.
2Productivity
If multiple computers concurrently project images using individual computers, then concurrent projection is enabled, but connection establishment becomes complex and time-consuming
Solution Approach 1:
The patent merges the connection establishment process by having projectors transmit group information that includes apparatus IDs of all projectors in the group. When a computer connects to one projector, the group information is used to automatically establish connections with all other projectors in the group, combining multiple connection operations into a single action and reducing overall system complexity for concurrent projection.
Solution Approach 2:
Group information acts as an intermediary mechanism that mediates between computers and multiple projectors. Instead of computers directly searching and registering with each projector individually, the group information serves as a shared reference that enables automatic connection establishment, simplifying the interaction and reducing complexity in concurrent projection scenarios.
3Ease of operation
If computers search and register projectors individually, then connection can be established, but the process becomes cumbersome and inefficient
Solution Approach 1:
The system implements self-service by having projectors automatically transmit group information to each other and store it locally. When a computer sends a connection request to any projector, the system uses the pre-stored group information to automatically establish connections with all projectors without requiring manual intervention or individual registration steps, making the connection process simple and efficient.

AI summary
A projector system includes: a plurality of computers connected to a network; and a plurality of projectors connected to the network, wherein each of the computers includes a connection request unit which gives a connection request to an arbitrary projector connected to the network, and each of the projectors includes a group information acquisition unit which acquires group information including apparatus IDs of the respective projectors of a group to which the own apparatus belongs, and a connection request unit which requests the projectors excluding the own apparatus among the projectors of the group to connection with an arbitrary computer, referring to the group information, when receiving the connection request from the arbitrary computer.
