Photosensitive Cartridge Electrode Guide for Stable Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photosensitive-body cartridges experience unstable power supply to the cleaning roller due to the electrode's movement in response to the cleaning roller's rotation, leading to inconsistent power delivery.
Innovation Solution
A photosensitive-body cartridge design that includes a primary electrode and a guide, where the primary electrode is positioned to move vertically within a guide groove, ensuring stable power supply to the cleaning roller by maintaining contact with an external electrode despite slight movements of the cleaning roller relative to the photosensitive drum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode follows the movement of the cleaning roller to maintain contact, then the electrode can continuously supply power to the moving cleaning roller, but the electrode slides against the main-body electrode causing unstable power supply
Solution Approach 1:
A guide member is introduced as an intermediary component between the electrode and the cleaning roller. The guide member includes a guide groove that constrains the electrode's movement path, allowing the electrode to follow the cleaning roller's rotation while preventing lateral sliding. This mediator enables continuous power supply to the moving cleaning roller while maintaining stable contact with the main-body electrode through the guided motion path.
2Productivity
If the cleaning roller moves relative to the photosensitive drum during rotation, then the cleaning roller can effectively clean the drum surface, but the electrode contact becomes unstable leading to inconsistent power delivery
Solution Approach 1:
The system transitions from a static electrode arrangement to a dynamic one where the electrode can move within the guide groove to follow the cleaning roller's rotation. The guide groove provides a controlled dynamic path that accommodates the cleaning roller's movement while maintaining electrical contact. This dynamic configuration allows the cleaning roller to effectively clean the drum surface while the electrode continuously supplies power through its guided motion.

AI summary
A photosensitive-body cartridge includes a photosensitive body, a cleaning roller, a primary electrode and a guide. The photosensitive body is configured to rotate together with a first rotational shaft extending in a first direction. The cleaning roller is configured to rotate together with a second rotational shaft parallel to the first rotational shaft and opposes the photosensitive body in a second direction perpendicular to the first direction. The primary electrode contacts one end of the second rotational shaft and is configured to supply power inputted from an external electrode to the cleaning roller. The guide is configured to guide the primary electrode to move in a third direction perpendicular to the first direction and intersecting the second direction.
