Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses do not optimize the amount of coloring material discharged onto the margin region for each type of coloring material, leading to inefficient flushing and potential image formation interruptions.
Innovation Solution
An image forming apparatus that specifies a margin region and generates image data for a pattern image based on the region's size and type of coloring material, optimizing the amount of material discharged for flushing and maintaining the liquid discharging head in a normal state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed amount of coloring material is discharged onto the margin region, then the image formation speed is enhanced, but the flushing effect is not optimized for each type of coloring material
Solution Approach 1:
The patent applies dynamics by making the amount of coloring material discharged variable rather than fixed. The control unit dynamically adjusts the discharge amount based on the detected type of coloring material, allowing the system to adapt to different material properties (e.g., viscosity, drying characteristics) while maintaining both high image formation speed and effective flushing.
Solution Approach 2:
The patent changes the parameter of coloring material discharge amount according to the material type. By detecting the coloring material type and adjusting the discharge quantity accordingly, the system optimizes the balance between maintaining high productivity and achieving reliable flushing effects for each specific material.
2Reliability
If the amount of coloring material discharged is increased to improve flushing, then the liquid discharging head is maintained in a normal state, but the image formation speed is reduced
Solution Approach 1:
The system changes the discharge amount parameter dynamically based on the coloring material type. By detecting material properties and adjusting the discharge quantity accordingly, the system achieves sufficient flushing to maintain liquid discharging head operation without excessively reducing image formation speed.
Solution Approach 2:
The patent implements dynamic adjustment of the discharge amount rather than using a fixed high amount. This allows the system to maintain reliable flushing and liquid discharging head operation while minimizing the impact on image formation speed through optimized, material-specific discharge quantities.
3Device complexity
If a uniform discharge amount is used for all coloring material types, then the system operation is simplified, but the flushing effectiveness varies by material type
Solution Approach 1:
The patent changes the discharge amount parameter based on the detected coloring material type. This allows the system to maintain relatively simple operation while achieving reliable flushing effectiveness for each material type through automated detection and adjustment.
Solution Approach 2:
The system incorporates feedback by detecting the coloring material type and using this information to adjust the discharge amount. This feedback mechanism allows the system to adapt to different material properties automatically, maintaining flushing effectiveness without significantly increasing operational complexity.

AI summary
An image forming apparatus for forming an image with a coloring material on a recording medium includes a region specifier that specifies a region that becomes a margin when the image is formed on the recording medium; and a pattern image generator that generates image data of a pattern image to be formed in the region based on a size of the region and a type of the coloring material.
