Processing Cartridge Movable Assembly Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processing cartridges face issues with the force bearing portion being prone to breakage during drops or collisions, leading to contamination of the photosensitive member due to its fixed installation, which prevents the developing and photosensitive members from separating effectively.
Innovation Solution
A movable assembly is introduced that can couple with the force applying portion, allowing the first and second units of the processing cartridge to switch between approaching and separating states, reducing the risk of breakage by providing a movable mechanism that can absorb shocks and impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the force bearing portion is fixedly installed in the toner bin to ensure coupling with the force applying portion, then the reliability of force transmission is improved, but the vulnerability to breakage during drops or collisions increases
Solution Approach 1:
The force bearing portion is changed from a fixed structure to a movable structure that can rotate relative to the toner bin around a rotation axis. This dynamic design allows the force bearing portion to absorb impacts and shocks by rotating, preventing breakage during drops or collisions while still maintaining reliable force transmission during normal operation when the force applying portion acts upon it.
2Ease of operation
If the force bearing portion is made prominent to ensure coupling with the force applying portion, then the ease of operation is improved, but the susceptibility to breakage during transportation increases
Solution Approach 1:
The force bearing portion is designed as a movable component that can rotate relative to the toner bin. This rotation capability allows it to remain prominent and easily couple with the force applying portion during operation, while simultaneously being able to absorb transportation shocks through rotational movement, preventing breakage.
3Object-affected harmful factors
If the toner bin is forced away from the waste toner bin to prevent photosensitive member contamination, then the protection of the photosensitive member is improved, but the structural stability decreases
Solution Approach 1:
The toner bin is designed to rotate relative to the waste toner bin around a rotation axis when the force applying portion acts on the movable force bearing portion. This rotational separation effectively prevents the photosensitive member from contacting the developing member and becoming contaminated, while the defined rotation axis provides structural stability and controlled movement.

AI summary
Provided is a processing cartridge detachably installed in an imaging device. The processing cartridge includes a first unit and a second unit, and a movable assembly coupled to and receive force from the force applying portion. When the processing cartridge is assembled to the imaging device, the first t and second units can be switched between states of approaching and separating. The movable assembly comprises an installing part and an acting part movable relative to and connectable with each other. The movable assembly is installed in the processing cartridge by the installing part, the acting part is coupled to the force applying portion and receives force from the force applying portion, to force the first and second units to switch between the two states. The acting part is retractable relative to the installing part and comprises an acting block and a guide block guided by the installing part.
