Developer Cartridge Gear Removal via Integrated Support Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing developer cartridges require cumbersome disassembly processes to remove gears for recycling, as the protection cover must be removed first, followed by individual removal of gears, which is inefficient.
Innovation Solution
A developer cartridge design featuring a support member that allows the transmission gears to be dismounted as an integral unit, along with the support member, simplifying the removal process by applying viscous drag to facilitate the extraction of the gears from the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protection cover is removed first and gears are removed one by one, then the gears can be dismounted, but the work becomes cumbersome and inefficient
Solution Approach 1:
The support member is designed to integrally hold multiple gears (first gear, second gear, third gear) so that they can be removed as a single unit from the housing. This merging of multiple gears onto one support member eliminates the need to remove each gear separately, directly addressing the technical contradiction by making the operation easier and reducing disassembly time.
Solution Approach 2:
The support member is segmented into multiple supporting portions (first supporting portion, second supporting portion, third supporting portion), each holding a specific gear. This segmentation allows the support member to be designed with modular gear-holding sections that can be collectively removed, solving the contradiction by enabling batch removal of multiple gears through a single disassembly action.
2Reliability
If multiple gears are held in the protection cover, then the driving force can be transmitted, but the disassembly process becomes complex
Solution Approach 1:
Multiple gears are merged onto a single support member structure, which is then removed as one unit from the housing. This reduces the disassembly process from multiple separate operations to a single operation, while the gears remain properly arranged to transmit driving force, thus reducing device complexity without sacrificing reliability.
Solution Approach 2:
The support member acts as an intermediary component that holds and positions multiple gears relative to each other and to the housing. By using this intermediary structure, the complex arrangement of multiple gears is simplified into a single removable assembly, reducing disassembly complexity while maintaining the necessary driving force transmission pathways.
3Ease of repair
If the development roller is removed for recycle use, then resources are saved, but the gears must also be removed individually
Solution Approach 1:
The support member with all gears attached is designed as a removable assembly that can be taken out from the housing as one unit. This allows the development roller and its associated gears to be removed together for recycling, greatly simplifying the process and making resource recovery more efficient without increasing device complexity.
Solution Approach 2:
The support member and gears are designed as recoverable components that can be removed and reused. By integrating the gears onto the support member, the system enables efficient recovery and recycling of these components, reducing waste and resource consumption while maintaining simple disassembly procedures.

AI summary
A developer cartridge includes a casing, a development roller, a support member, and at least one transmission gear. The development roller is rotatably disposed in the casing. The support member is provided as a separate member from the casing and is mounted on the casing. The at least one transmission gear is rotatably supported by the support member. The at least one transmission gear transmits a driving force to the development roller. The support member is configured to be dismounted from the casing together with the at least one transmission gear.
