Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to prevent memory units from detaching from cartridges in image forming apparatuses, which are essential for storing and transmitting information related to the cartridge's characteristics and maintenance within the image forming apparatus.
Innovation Solution
A cartridge design that includes a memory member with electric contacts and a support member featuring a memory mounting portion with a groove structure, where the memory member is bonded to the support member using an adhesive, ensuring secure attachment and electrical connectivity when installed in the image forming apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a memory is mounted on a cartridge using only an adhesive, then the mounting process is simple, but the memory may drop off the cartridge
Solution Approach 1:
The support member is divided into a flat portion and a protruding portion with different functions. The flat portion provides a bonding surface for the adhesive, while the protruding portion extends beyond the memory to prevent it from dropping off, creating a segmented structure that addresses both mounting simplicity and attachment reliability.
Solution Approach 2:
The support member transitions from a two-dimensional flat surface to a three-dimensional structure with a protruding portion that extends vertically beyond the memory component. This dimensional change creates a physical barrier that prevents the memory from dropping off while maintaining the simplicity of adhesive-based mounting.
2Reliability
If the support member is made larger to prevent memory from dropping off, then attachment reliability improves, but the cartridge size increases
Solution Approach 1:
Instead of increasing the overall size of the support member uniformly, the invention applies a localized protruding portion only at the specific area needed to prevent memory from dropping off. This local quality approach maintains compact cartridge dimensions while providing enhanced attachment reliability where required.
Solution Approach 2:
The solution addresses the reliability issue by extending the support member in the vertical dimension (height) rather than increasing the horizontal footprint. This allows the memory to be secured against dropping off without significantly increasing the cartridge's planar dimensions or overall volume.
