Intermediary Transfer Unit Memory Layout for Cleaning Unit Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses with detachable belt cleaning devices, the exchange of the cleaning device results in a loss of information about the use history on the frame unit side, complicating environmental sustainability and maintenance efficiency.
Innovation Solution
The implementation of a memory substrate on the frame unit of the intermediary transfer unit to store information, allowing for the retention of use history even when the belt cleaning device is exchanged, and simplifying the connection between the memory substrate and the apparatus main assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the belt cleaning device is made detachably mountable to the frame unit, then the ease of repair is improved, but the loss of information occurs when the cleaning device is exchanged
Solution Approach 1:
The intermediary transfer unit is divided into two detachable parts: the frame unit (containing the intermediary transfer belt and stretching rollers) and the belt cleaning device. This segmentation allows the cleaning device to be exchanged independently for maintenance purposes while preserving the frame unit with its memory substrate intact.
Solution Approach 2:
The memory substrate is positioned on the frame unit side and serves as an intermediary information storage device that maintains use history data even when the belt cleaning device is exchanged. This mediator ensures information continuity despite component replacement.
2Ease of operation
If the memory substrate is mounted on the belt cleaning device, then the ease of operation is improved for cleaning device replacement, but the device complexity increases due to the need to maintain connection during detachment
Solution Approach 1:
The system is segmented into the frame unit with memory substrate and the separately exchangeable belt cleaning device. This segmentation eliminates the need for complex connection mechanisms between the memory substrate and the cleaning device, as the memory substrate remains on the frame unit.
Solution Approach 2:
The memory substrate is extracted from the belt cleaning device and placed on the frame unit. This extraction simplifies the overall system by removing the need for connection mechanisms between the memory substrate and the detachable cleaning device, reducing device complexity while maintaining operational ease.
