Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single analytical method is used to generate jet parameters for both drop volume control and ejection speed control, then the system structure is simple, but the prediction accuracy for both standards cannot be optimized simultaneously
Solution Approach 1:
The patent segments the analytical method into two distinct standard-specific methods: a first analytical method for drop volume control and a second analytical method for ejection speed control. Each method is tailored to its specific standard, allowing optimized prediction accuracy for each while maintaining clear system structure through modular organization of the parameter generation section.
2Ease of operation
If all input parameters are used as explanatory variables for both standards, then the system is easy to operate, but the calculation complexity and processing time increase
Solution Approach 1:
The patent applies local quality by selecting different subsets of explanatory variables tailored to each standard's specific requirements. The parameter generation section automatically selects relevant input parameters based on the chosen standard, using only the necessary variables for each calculation type. This reduces processing time while maintaining ease of operation through automated selection.
3Adaptability or versatility
If voltage values are set without standardized methods, then the system is flexible, but the manufacturing precision and consistency of inkjetting quality deteriorate
Solution Approach 1:
The patent implements parameter changes by establishing standardized voltage value settings based on two distinct standards: drop volume control and ejection speed control. The system selects and applies the appropriate standard according to specific requirements, ensuring manufacturing precision and consistency through methodical parameter selection while maintaining adaptability to different application needs.

AI summary
A jet parameter generation system according to an embodiment of the present disclosure includes a data acquisition section, and a parameter generation section for generating a predetermined jet parameter, using a predetermined analytical method of taking a predetermined input parameter as an explanatory variable and taking a predetermined jet parameter as an objective variable. The parameter generation section determines which one of a first standard for setting a voltage value with which a drop volume of the liquid to be a reference is obtained and a second standard for setting a voltage value with which an ejection speed of the liquid to be a reference is obtained is to be selected, selects a first explanatory variable group when determining to select the first standard, while selecting a second explanatory variable group when determined to select the second standard, and uses the predetermined analytical method using just selected one of the first explanatory variable group and the second explanatory variable group to thereby generate the predetermined jet parameter.
