Connection Control for Reserved Main Display Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection control devices limit the number of connections, preventing the main display device from connecting when the number of connections is already at the limit due to auxiliary display devices, leading to potential resource overconsumption.
Innovation Solution
A connection control device with a determination unit that ensures a predetermined type of device, such as a main display device, can connect by allowing connections if there are sufficient available slots, while rejecting connections for auxiliary devices when necessary, thereby guaranteeing the connection of main devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of connections is limited to avoid resource overconsumption, then resource usage is controlled, but the main display device cannot connect when auxiliary devices occupy all available connections
Solution Approach 1:
The patent applies local quality by assigning different connection priorities to different device types. Main display devices are granted higher priority (first priority) while auxiliary display devices receive lower priority (second priority). This differentiated quality assurance allows the system to guarantee connections for critical devices while still permitting non-critical connections when resources are available, resolving the contradiction between connection reliability and adaptability.
2Adaptability or versatility
If connections are permitted for all devices when slots are available, then connection flexibility is maintained, but main display devices may be denied connection when auxiliary devices occupy all slots
Solution Approach 1:
The patent implements preliminary action by reserving connection slots for main display devices before auxiliary devices can occupy them. The connection control device checks whether a main display device is present before permitting auxiliary device connections. This advance reservation ensures that main devices are guaranteed connection access, preventing the scenario where auxiliary devices block main devices from connecting.
3Productivity
If the system allows multiple auxiliary display devices to connect, then resource utilization increases, but the main display device connection is compromised
Solution Approach 1:
The patent employs feedback mechanisms where the connection control device continuously monitors the connection status and device types. When a main display device connection request is received, the system checks current connection status and prevents auxiliary device connections that would block main device access. This real-time feedback control allows the system to dynamically adjust connection permissions, maintaining high resource utilization while guaranteeing main device connectivity.

AI summary
A connection control device according to an embodiment comprises a determination unit and a connection control unit. The determination unit determines whether a first device is a device of a first type among a plurality of types. When the connection control unit has received a request from the first device to connect with a second device, if the first device is not a device of the first type, the connection control unit allows the connection with the second device if there is a number of spaces greater than or equal to (N+1-(number of first devices of the first type that have established a connection with the second device)) among the number of possible connections (where N is an integer greater than or equal to 1), and refuses the connection with the second device if this is not the case.
