Solution Overview
Problem
Existing toner production methods face challenges in achieving compatibility between different color toners due to unpredictable triboelectric charging properties, leading to incompatibility and difficulties in forming custom colors, especially with small particle sizes which affect print quality and stability.
Innovation Solution
A process is developed to adjust the triboelectric charging characteristics of toner particles by controlling the blending parameters such as intensity and duration, allowing for the combination of toners with identical additive packages and resin bases to achieve equivalent triboelectric charging rates, enabling the formation of new colors with improved compatibility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional toner production methods are used, then toner particles can be formed, but triboelectric charging properties become unpredictable leading to incompatibility between different color toners
Solution Approach 1:
The patent changes the triboelectric charging parameters by controlling blending intensity and duration, adjusting the charging rate to achieve equivalence across different color toners. This resolves the unpredictability of triboelectric charging while maintaining color toner compatibility for custom color formation.
Solution Approach 2:
The patent applies preliminary triboelectric charging treatment to toner particles before blending different colors. By pre-adjusting the charging characteristics through controlled blending, the patent ensures compatibility when forming custom colors, preventing the incompatibility that would otherwise occur.
2Manufacturing precision
If small particle size toners are used, then print quality can be improved, but stability and compatibility issues arise due to triboelectric charging variability
Solution Approach 1:
The patent changes the triboelectric charging parameters specifically for small particle size toners by adjusting blending intensity and duration. This control compensates for the increased variability in triboelectric charging that occurs with smaller particles, maintaining both print quality and toner stability.
3Adaptability or versatility
If different color toners are blended to form custom colors, then color versatility is improved, but incompatibility occurs due to different triboelectric charging properties
Solution Approach 1:
The patent applies preliminary triboelectric charging adjustment to each color toner before blending. By pre-controlling the charging rate through standardized blending parameters, the patent ensures that different color toners remain compatible when blended, enabling reliable custom color formation.
Solution Approach 2:
The patent achieves equipotentiality in triboelectric charging across different color toners by controlling the blending process to produce equivalent charging rates. This equalizes the electrostatic properties of different colors, allowing them to blend compatibly for custom color formation.
