Inclined Cleaning Roller for Efficient Inkjet Roller Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller cleaning methods in inkjet devices are inefficient in spreading cleaning liquid to the roller, affecting the cleaning efficiency.
Innovation Solution
A cleaning liquid is supplied to a roller inclined with respect to the horizontal direction, allowing it to spread efficiently via gravity, and a cleaning block contacts the roller to enhance cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning liquid is supplied to a horizontal roller, then the cleaning liquid can be supplied, but it does not spread efficiently across the roller surface
Solution Approach 1:
The roller is designed with an inclined surface rather than a horizontal surface. The cleaning liquid supplier directs cleaning liquid onto the inclined roller surface, where gravity causes the liquid to spread downward along the incline, ensuring efficient coverage of the roller surface without requiring additional spreading mechanisms.
2Productivity
If a cleaning block contacts the roller to clean it, then cleaning can be performed, but the cleaning efficiency is insufficient without effective cleaning liquid distribution
Solution Approach 1:
The inclined roller surface creates a gravitational field where cleaning liquid naturally flows downward, ensuring uniform distribution across the roller surface. This gravitational flow creates an equipotential cleaning effect where the cleaning liquid reaches all necessary areas of the roller without requiring additional pumping or distribution mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cleaning liquid spreads effectively across the roller, improving the cleaning efficiency by ensuring thorough coverage and removal of adhering substances.
Implementation Method 1
The cleaning liquid supplied to the roller in this way moves downward by gravity. At this time, since the roller is inclined with respect to the horizontal direction, the cleaning liquid spreads also in an extension direction of the roller according to a downward movement.

AI summary
The cleaning roller extends in the width direction inclined with respect to the Y direction. The cleaning liquid is supplied to this cleaning roller from above. The cleaning liquid supplied to the cleaning roller in this way moves downward by gravity. At this time, since the cleaning roller is inclined with respect to the Y direction, the cleaning liquid spreads also in an extension direction of the cleaning roller (i.e. width direction) according to a downward movement.
