Processing Cartridge With Retractable Force Receiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing cartridges in electronic image forming devices are prone to jamming due to the unexpected protrusion of the first force receiving element during installation, leading to installation issues and interference with internal components.
Innovation Solution
The processing cartridge features a first force receiving element with multiple position states, including a second position state where it is closer to the housing, and a locking mechanism to prevent movement, along with a movable element that retracts relative to the protrusion, preventing vertical retraction and ensuring smooth installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first force receiving element is made protruding to receive driving force, then the driving force transmission is improved, but the cartridge is prone to jamming during installation
Solution Approach 1:
The first force receiving element is designed to be movable between a first position (retracted) and a second position (protruding). During installation, it is in the first position to avoid jamming. After installation, it moves to the second position to receive driving force from the second force receiving element, thus resolving the contradiction between installation smoothness and driving force transmission.
Solution Approach 2:
The first force receiving element is positioned in advance (in the retracted first position) before the installation process completes, preventing jamming during installation. After installation is complete, it transitions to the protruding second position to perform its function of receiving driving force, embodying the preliminary action principle.
2Ease of operation
If the first force receiving element is made movable to prevent jamming, then the installation smoothness is improved, but the position stability deteriorates
Solution Approach 1:
The first force receiving element transitions from a static design to a dynamic one, with defined movement between two stable positions (first position for installation, second position for operation). This dynamic design allows it to be retracted during installation for smoothness, then stabilized in the protruding position for reliable force reception, resolving the contradiction between movement and stability.
Solution Approach 2:
The first force receiving element automatically transitions between positions based on operational needs. During installation, it self-retracts to the first position. After installation, it self-positions to the second position to receive driving force, eliminating the need for external control mechanisms while maintaining both installation smoothness and position stability.
3Ease of operation
If the first force receiving element is retracted during installation, then the jamming is prevented, but the driving force reception is compromised
Solution Approach 1:
The first force receiving element dynamically adjusts its position based on the operational phase: retracted (first position) during installation to prevent jamming, and protruding (second position) during operation to receive driving force. This temporal separation of positions resolves the contradiction between installation smoothness and driving force reception.
Solution Approach 2:
The first force receiving element is preliminarily positioned in the retracted first position before the driving force transmission phase begins, ensuring smooth installation. After installation is complete, it transitions to the protruding second position to perform its primary function of receiving driving force, thus resolving the contradiction through sequential positioning.

AI summary
A processing cartridge can be detachably installed in an electronic image forming device, where a protrusion capable of extending and retracting along a vertical direction is disposed inside the electronic image forming device. The processing cartridge includes a toner container and a waste toner container; and a movable element disposed at the lower side of the processing cartridge. The processing cartridge further includes a detachment preventing portion; the movable element is disposed with an abutting portion; and the abutting portion is capable of being abutted against the detachment preventing portion to prevent the movable element being disengaged. The processing cartridge further includes an elastic element; and the elastic element is configured to move the movable element toward the lower side of the processing cartridge.
