Drive Pulse Waveform Settings with Bundled Condition Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in improving usability when determining the waveform of drive pulses for discharge characteristics, as users often repeat the same target and measurement conditions without the ability to easily adjust them for different configurations.
Innovation Solution
An information processing apparatus that includes reception units for inputting first and second information items to determine the waveform of drive pulses, allowing for the collective reception of pre-stored information to simplify the setting process and enhance usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple setting items for determining drive pulse waveform are input individually, then the determination precision is improved, but the operation complexity increases
Solution Approach 1:
The patent combines multiple setting items (target conditions and measurement conditions) into a single composite setting input. The reception unit receives a bundled input containing both target conditions (discharge amount, discharge frequency, discharge rate) and measurement conditions (reference waveform, discharge pattern) together, rather than requiring separate inputs for each setting item. This merging approach maintains the precision of individual settings while significantly reducing the operational burden on users.
2Measurement precision
If multiple setting items for determining drive pulse waveform are input individually, then the determination precision is improved, but the time consumption increases
Solution Approach 1:
By merging multiple setting items into a single composite input that is processed together, the patent eliminates the sequential time required to input each setting item individually. The reception unit accepts the bundled settings in one operation, and the determination unit processes all settings simultaneously, thereby maintaining precision while dramatically reducing the time required to complete the waveform determination process.

AI summary
An information processing apparatus used to determine a waveform of a drive pulse applied to a drive element provided in a liquid discharge head for discharging a liquid includes a first reception unit that receives an input of first information regarding a first setting item for determining the waveform of the drive pulse, a second reception unit that receives an input of second information regarding a second setting item different from the first setting item for determining the waveform of the drive pulse, and a third reception unit that collectively receives the inputs of the first information and the second information from information stored in advance.
