Waste Developer Conveying Mechanism for Compact Image-Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image-forming devices face challenges in efficiently managing waste toner within the system, particularly in integrating a waste toner collection mechanism that is compact and easy to replace, while maintaining optimal operation of the developer material supply and recovery processes.
Innovation Solution
The image-forming device incorporates a waste developer material conveying mechanism connected to a waste developer material accommodating part, which collects waste toner from the recovering unit and conveys it to an integrated waste developer material accommodating part, allowing for efficient waste toner management and replacement without disrupting the developer material supply process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a waste toner collecting unit is integrated with the developer cartridge, then replacement is simplified, but the device complexity increases
Solution Approach 1:
The waste toner collecting unit is integrated with the developer cartridge as a single replaceable assembly. The waste developer material accommodating part is positioned adjacent to the developer material accommodating part, and both are covered by a common housing structure, allowing simultaneous replacement of both functional units.
2Volume of moving object
If the waste developer material accommodating part is integrated with the developer material accommodating part, then space is saved, but the conveying mechanism complexity increases
Solution Approach 1:
The waste developer material accommodating part is positioned within the housing structure that also contains the developer material accommodating part. The conveying member is arranged to pass through or alongside these accommodated parts, creating a nested spatial arrangement that optimizes space utilization.
3Ease of operation
If the conveying member is disposed outside the waste developer material accommodating part, then access is improved, but the structural complexity increases
Solution Approach 1:
The conveying member acts as an intermediary element that connects the recovering unit to the waste developer material accommodating part. It is disposed in a position that allows it to interact with both components while remaining accessible for maintenance and replacement operations.

AI summary
In an image-forming device, a waste developer material accommodating part is provided integrally with a developer material accommodating part and is configured to accommodate waste developer material collected by a recovering unit. A waste developer material conveying mechanism is connected to both of the recovering unit and the waste developer material accommodating part and conveys the waste developer material from the recovering unit to the waste developer material accommodating part. The waste developer material conveying mechanism includes a conveying member that is disposed outside the waste developer material accommodating part and that is coupled to a center region of the waste developer material accommodating part along an axial direction of the photosensitive drum.
