Cartridge Memory and Display Member Insertion Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming cartridges face challenges in downsizing memory components while ensuring accurate assembly and preventing movement of memory and color display members, which affects the efficiency and cost of maintenance and recycling.
Innovation Solution
The cartridge design incorporates a first and second supporting portion with slits for inserting memory and color display members, respectively, and preventing portions to secure them in place, allowing for easy assembly and disassembly, and reducing the overall size by sharing a common insertion direction and using rigid components for improved handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If memory and color display members are fixed using conventional methods (thermal caulking, double-side tape), then they can be secured in place, but the cartridge size cannot be reduced and manufacturing complexity increases
Solution Approach 1:
The cartridge is divided into separate components: a frame, a cover member, and independently insertable memory and color display members. This segmentation allows each component to be manufactured separately and assembled through simple insertion into designated slots, reducing overall manufacturing complexity while enabling compact sizing.
Solution Approach 2:
The memory member and color display member are nested within the cartridge structure, with each member inserted into its own designated slot within the frame or cover member. This nesting approach allows compact arrangement of components, reducing cartridge volume while maintaining ease of assembly through simple insertion without requiring complex fixing mechanisms.
2Ease of repair
If memory and color display members are made detachable for easy maintenance, then maintenance efficiency improves, but positioning accuracy and reliability deteriorate
Solution Approach 1:
The frame and cover member are pre-equipped with designated slots and preventing portions before assembly. These features are built into the structure in advance, ensuring that when memory and color display members are inserted, they automatically achieve accurate positioning and secure fixation without requiring complex alignment procedures or additional fixing steps.
Solution Approach 2:
The slot and preventing portion structure acts as an intermediary mechanism between the detachable memory/color display members and the cartridge frame. This intermediary structure provides both easy detachability for maintenance and reliable positioning accuracy by guiding insertion and preventing movement, simultaneously satisfying both requirements.
3Adaptability or versatility
If multiple components (memory, color display member) are assembled separately, then adaptability and ease of replacement improve, but device complexity increases
Solution Approach 1:
The frame and cover member serve multiple functions: they provide structural support, contain designated slots for both memory and color display members, and include preventing portions to secure both components. This multi-functional design allows separate, easily replaceable components while avoiding increased overall device complexity through efficient structural integration.

AI summary
A cartridge includes: first and second cartridge constituent members assembled with each other; a memory for storing information on the cartridge; a color display member for displaying color information of a developer accommodated in the cartridge; first and second supporting portions provided on the first and second cartridge constituent members, wherein the first supporting portion is provided with a slit for permitting insertion of the memory, and the second supporting portion is provided with a slit for permitting insertion of the color display member; and first and second preventing portions provided on the other cartridge constituent member. When the first and second cartridge constituent members are assembled with each other, the first preventing portion prevents movement of the memory inserted in the first supporting portion, and the second preventing portion prevents movement of the color display member inserted in the second supporting portion.
