Pivotable Cover Latch for Developing Unit Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image forming apparatuses require complex processes to detach the developing unit, making it difficult to replace or maintain, as they involve multiple external forces and steps to open and separate the supporting cover and the developing unit from the main body.
Innovation Solution
The image forming apparatus incorporates a pivotably mounted cover with a latch and a supporting member that rotates between supporting and releasing positions, facilitated by a gear member and elastic bias, allowing for simpler detachment by transmitting external forces through a handle, enabling easier opening and closing of the supporting cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a latch and supporting member are used to secure the developing unit, then the stability of the developing unit is improved, but the complexity of detaching the developing unit increases
Solution Approach 1:
The latch and supporting member are combined into a single integrated component that performs both functions simultaneously. When the cover is opened, the latch releases from the locked position and the supporting member rotates to support the photoconductive medium shaft, enabling both securing and supporting functions to be achieved by one mechanism rather than two separate components.
Solution Approach 2:
The supporting member is designed to be rotatable rather than fixed, allowing it to dynamically change position between a non-supporting state (when the cover is closed) and a supporting state (when the cover is open). This dynamic capability enables the same component to serve different functions at different times, simplifying the overall detachment process.
2Reliability
If multiple external forces are applied to open the supporting cover, then the cover can be securely opened, but the ease of operation deteriorates
Solution Approach 1:
The latch release function and supporting member rotation function are merged into a single cover opening motion. The user applies one external force to open the cover, and this single action simultaneously releases the latch from its locked position and rotates the supporting member into its supporting position, eliminating the need for multiple separate operations.
Solution Approach 2:
The latch is positioned and configured in advance so that when the cover is opened, the release of the latch occurs automatically as part of the cover opening motion. The supporting member is also pre-positioned to rotate into its supporting role as the cover opens, so the user does not need to manually perform separate actions to release the latch or position the supporting member.

AI summary
Disclosed herein is an image forming apparatus including a main body; a developing unit detachably mounted on the main body and having a photoconductive medium; and a cover pivotably mounted on the main body to cover and support an outer end of the developing unit. The cover may have a latch engaged with the main body by one end thereof so that the cover supports the developing unit. A member that supports a shaft of the photoconductive medium may also be included. Because the member operates in association with the latch, opening and closing of the cover may be facilitated, accordingly also facilitating separation of the developing unit from the main body.
