Cartridge Package Segmented Closing Member for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge packages for image forming apparatuses are complex in structure, making them costly and difficult for users to open and remove the cartridge, which complicates the process of installing or replacing cartridges in image forming apparatuses.
Innovation Solution
A cartridge package design featuring a frame portion with a recess for accommodating the cartridge, a closing member portion that is openably connected via a hinge portion to the frame, and a connecting portion that allows the closing member to be separated from the frame, simplifying the structure and making it easier to open and remove the cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cartridge package is designed with multiple lids and complex sealing structures to protect the cartridge during transportation, then the protection reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The package body is divided into a main body and a detachable closing member, allowing the sealing function to be separated from the container structure. This segmentation enables simpler manufacturing of each component while maintaining effective sealing through the connection between parts.
Solution Approach 2:
The closing member is designed to be movable relative to the main body through a hinge connection, transitioning between open and closed states. This dynamic design simplifies the overall structure compared to fixed multi-lid configurations while maintaining protection functionality.
2Reliability
If a cartridge package uses multiple detachable lids to secure the cartridge, then the protection against vibrations and impacts is improved, but the ease of operation deteriorates as users must manually separate and reattach multiple lids
Solution Approach 1:
Multiple sealing functions that were previously distributed across separate lids are merged into a single integrated closing member. This reduces the number of separate components the user must interact with while maintaining the protective sealing function.
Solution Approach 2:
The hinge connection enables a dynamic opening mechanism where the closing member can be easily rotated or moved to open the package. This dynamic design allows users to access the cartridge quickly without manually separating multiple rigid lids.
3Reliability
If a cartridge package is designed with a tight sealing structure to prevent contamination, then the protection reliability is improved, but the ease of manufacture deteriorates due to complex assembly requirements
Solution Approach 1:
The sealing structure is segmented into distinct components (main body and closing member) that can be manufactured separately using standard molding or fabrication processes. This reduces manufacturing complexity compared to creating a single complex sealed structure.
Solution Approach 2:
The connection between the main body and closing member acts as an intermediary mechanism that provides sealing functionality. This intermediate connection structure simplifies the overall manufacturing process by allowing modular assembly rather than requiring a monolithic sealed design.
