Retractable Toner Cartridge Layout for Easier Rotary Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses with rotary developing systems face challenges in efficiently and conveniently replacing toner cartridges, leading to operational inefficiencies and reduced user-friendliness.
Innovation Solution
The image forming apparatus incorporates a rotary system with first and second developing rollers, each with a storage frame and a toner cartridge that is retractable and attachable, supported by movable support members, allowing for easy replacement and supply of toner to the developing rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If toner cartridges are made detachable and retractable for easy replacement, then ease of operation is improved, but device complexity increases due to additional support members and movable mechanisms
Solution Approach 1:
The support members are designed to be movable rather than fixed, allowing them to automatically adjust position as toner cartridges are removed or installed. This dynamic capability enables the support structure to adapt to different cartridge configurations without requiring complex manual adjustment mechanisms
Solution Approach 2:
The support members automatically perform their supporting function without external intervention. When toner cartridges are placed on the support members, they are automatically held in position, and when cartridges are removed, the support members automatically retract or adjust, eliminating the need for additional control mechanisms
2Productivity
If multiple toner cartridges are stored in the rotary system, then productivity is improved through continuous image formation, but ease of operation deteriorates due to difficulty in accessing individual cartridges
Solution Approach 1:
The rotary system is divided into multiple independent storage frames, each capable of holding individual toner cartridges. This segmentation allows each cartridge to be independently accessed, removed, or replaced without affecting the other cartridges in the system, maintaining both high productivity and ease of operation
Solution Approach 2:
The support members are positioned in multiple spatial dimensions around the rotary system, allowing cartridges to be accessed from different directions. This multi-dimensional arrangement enables convenient access to any cartridge without requiring the entire rotary system to be stopped or disassembled

AI summary
An image forming apparatus includes a first toner cartridge to store first toner and is movable to a first attached position and a first retracted position with respect to a storage frame, and a second toner cartridge to store second toner and is movable to a second attached position and a second retracted position with respect to a second storage frame. A movable first support member supports the first toner cartridge, and a movable second support member supports the second toner cartridge. In a case where a length by which the first toner cartridge at the first retracted position projects from an opening in a body frame is a first length and a length by which the second toner cartridge at the second retracted position projects from the opening is a second length, the first length is larger than the second length.
