Vacuum Connection Device with Communication Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum device systems can only connect to a maximum of one operating device due to single communication ports, limiting flexibility and requiring interruptions in connections for multi-device setups, especially in large areas where direct access to PCs is difficult.
Innovation Solution
A connection device with a first connection for a vacuum device and multiple second connections for operating devices, featuring a communication control unit that forwards messages from each operating device to the vacuum device, ensuring sequential processing of requests and prioritization to prevent errors and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single communication port is used for connection, then the device structure is simple, but only one operating device can be connected at a time
Solution Approach 1:
The communication interface is segmented into multiple second connections (32, 33) while maintaining a single first connection (31) to the vacuum device. This segmentation allows multiple operating devices to connect simultaneously through separate ports, resolving the contradiction between connection versatility and structural simplicity.
Solution Approach 2:
The connection device (30) acts as an intermediary between the vacuum device and multiple operating devices. It receives messages from multiple second connections, manages communication sequencing, and forwards them through the single first connection, enabling multi-device connectivity without requiring the vacuum device itself to have multiple ports.
2Ease of operation
If multiple operating devices are connected simultaneously, then operational flexibility is improved, but communication control complexity increases
Solution Approach 1:
The communication control unit dynamically manages message routing and timing based on the state of ongoing communications. It monitors which operating device is currently being served and adjusts message forwarding accordingly, providing adaptive control that handles multiple devices flexibly without requiring rigid predefined configurations.
Solution Approach 2:
The system uses feedback mechanisms where the communication control unit monitors communication status from the vacuum device and adjusts its message forwarding behavior. When a message is being processed, the unit receives feedback about the communication state and uses this to control when to accept and forward messages from different operating devices, preventing conflicts while maintaining ease of operation.
3Reliability
If message forwarding is done without sequencing, then communication speed is fast, but communication errors may occur
Solution Approach 1:
The communication control unit performs preliminary checks before forwarding messages to determine if the vacuum device is currently engaged in communication. It proactively manages the communication queue and timing, preparing to forward messages at appropriate intervals rather than attempting simultaneous transmission, which ensures reliability while minimizing unnecessary delays.
