Ink Jet System Dual-Server Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink jet systems face issues when a single in-cloud server is used, including program updates disrupting functionality, decreased processing speed due to concentrated access, and inability to retrieve previously set control information during server updates or high usage periods, which affects the reliability and usability of recording operations.
Innovation Solution
The ink jet system employs a dual-server configuration where one server generates and accumulates control information, allowing continuous operation even during updates, and another server handles data processing and storage, distributing the processing load and ensuring uninterrupted recording operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single in-cloud server is used to store and execute recording programs, then device complexity is reduced, but reliability deteriorates because the recording operation cannot be executed when the program is being updated
Solution Approach 1:
The single server is segmented into two separate servers: a first server dedicated to storing and managing recording programs, and a second server dedicated to executing recording operations. This segmentation allows the first server to be updated without affecting the operational capability of the second server, thereby maintaining system reliability while keeping the overall configuration relatively simple.
Solution Approach 2:
The first server acts as an intermediary that stores and manages recording programs, while the second server executes these programs. The head unit can retrieve programs from the first server and execute them locally on the second server, creating a mediator role that separates program management from program execution, ensuring continuous operation during updates.
2Device complexity
If a single in-cloud server handles all data processing and storage, then device complexity is reduced, but productivity deteriorates due to decreased processing speed from concentrated access
Solution Approach 1:
The server functions are segmented into program management (first server) and execution processing (second server). This division distributes the processing load across two separate systems, preventing the concentration of all access operations on a single server and thereby maintaining or improving overall data processing speed.
3Device complexity
If control information is stored on a single server, then information management is simplified, but loss of information occurs when the server is updated or inaccessible
Solution Approach 1:
Control information and recording programs are separated and stored on different servers. The first server stores recording programs while the second server handles execution and can access previously stored control information. This segmentation ensures that control information is preserved and accessible even when one server is being updated or is temporarily inaccessible.

AI summary
An ink jet system includes: a first subsystem including at least a first recording apparatus and a first processing apparatus, the first recording apparatus being equipped with a first head unit that ejects ink and being configured to execute a recording operation on a recording medium, the first processing apparatus performing data processing for causing the first recording apparatus to execute the recording operation; a second subsystem including at least a second recording apparatus and a second processing apparatus, the second recording apparatus being equipped with a second head unit that ejects ink and being configured to execute a recording operation on a recording medium, the second processing apparatus performing data processing for causing the second recording apparatus to execute the recording operation; a first server connected to both the first subsystem and the second subsystem; and a second server connected to the first server.
