Solution Overview
Problem
Existing liquid discharge apparatuses in line head systems face challenges in adjusting correction values for non-discharge issues, as these values are not appropriate for different types of discharge targets, affecting image quality.
Innovation Solution
A discharge control apparatus with a storage control unit and a correction value update unit that stores and updates correction values specifically for each type of discharge target, allowing for appropriate correction values to be applied based on user input and type of discharge target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single correction value is used for all discharge targets, then the device complexity is reduced, but the image quality deteriorates due to inappropriate correction values for different discharge target types
Solution Approach 1:
The patent segments the correction values by discharge target type, storing different correction values for different types of discharge targets (e.g., porous vs. non-porous materials). This segmentation allows appropriate correction values to be selected based on the specific discharge target type, thereby improving image quality without significantly increasing device complexity through structured data organization.
Solution Approach 2:
The patent changes the parameter of correction values based on the discharge target type. By adjusting the correction values according to the specific properties of different discharge targets (such as porosity, surface texture), the system optimizes discharge accuracy for each target type, resolving the contradiction between using a single correction value and achieving high image quality.
2Manufacturing precision
If correction values are optimized for each discharge target type, then the image quality is improved, but the device complexity increases due to multiple correction values to manage
Solution Approach 1:
The patent segments correction values by discharge target type and stores them in an organized manner in storage units. This segmentation strategy improves image quality through type-specific optimization while managing complexity through structured data organization, where each discharge target type has its dedicated correction value set.
Solution Approach 2:
The patent creates a universal correction value management system that handles multiple discharge target types through a unified approach. The system stores and manages multiple correction values in a standardized format, allowing the same management mechanism to serve multiple functions across different discharge target types, thereby reducing the perceived complexity.
3Ease of operation
If a predetermined correction value is used, then the ease of operation is improved, but the reliability of discharge accuracy deteriorates for different discharge target types
Solution Approach 1:
The patent implements a dynamic correction value selection mechanism that automatically chooses the appropriate correction value based on the detected discharge target type. This dynamic approach maintains ease of operation through automatic selection while improving reliability by ensuring the most appropriate correction value is applied for each specific discharge target type.
Solution Approach 2:
The patent incorporates a feedback mechanism where the system detects the discharge target type and selects the corresponding correction value from storage. This feedback loop ensures that the appropriate correction value is applied based on the actual discharge target being used, thereby maintaining both ease of operation and high reliability of discharge accuracy.

AI summary
A discharge control apparatus includes a storage control unit, and a correction value update unit. The storage control unit is configured to store, in a storage unit, a correction value for correcting a value related to discharge performed by a liquid discharge unit configured to discharge liquid to a discharge target, in association with a type of the discharge target. The correction value update unit is configured to update, via the storage control unit, the correction value stored in the storage unit, based on input received by an input receiving unit configured to receive the input from a user. The correction value update unit is configured to perform update with as identical correction value for a plurality of different types of discharge targets.
