Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single MPU controls printing control of each nozzle in common, then device complexity is reduced, but processing speed of information about printing dots is limited
Solution Approach 1:
The control system is segmented into multiple independent MPUs, each dedicated to controlling specific nozzles. This segmentation allows parallel processing of printing information for different nozzle groups, thereby increasing overall processing speed while maintaining manageable device complexity through modular architecture
2Productivity
If control is performed with a plurality of MPUs, then processing speed is improved, but a deviation in timing of starting the printing is incurred for each nozzle
Solution Approach 1:
A feedback mechanism is implemented where each MPU monitors the printing start signals received from other MPUs and adjusts its own timing accordingly. This feedback loop ensures that all nozzles synchronized their printing start timing despite having independent control clocks, resolving the timing deviation issue while maintaining high processing speed
Solution Approach 2:
The system establishes a common reference timing level for all MPUs by having them wait for printing start signals from all other MPUs before initiating printing. This creates an equipotential timing state where all nozzles operate at the same timing level, eliminating deviations while preserving the parallel processing benefits
3Device complexity
If an inkjet recording device with only one nozzle is used, then device complexity is reduced, but the size of ink particle that can be deflected is limited
Solution Approach 1:
The printing system is divided into multiple nozzle groups, each controlled by a dedicated MPU. This segmentation allows the device to handle larger ink particles by distributing the deflection task across multiple nozzles, thereby increasing adaptability to different ink particle sizes while maintaining manageable device complexity through modular control architecture
