Memory Holder Guide Groove Alignment for Image Forming Cartridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The attachment and detachment of cartridges in image forming apparatuses experience increased resistance when the attaching direction is not parallel to the electrical contact surface of the memory, leading to inefficient cartridge handling.
Innovation Solution
The design incorporates a guide groove with upper and lower guide surfaces in the main housing, which guides the memory holder to ensure the electrical contact surface is parallel to at least part of these surfaces during attachment and detachment, reducing resistance by allowing the memory holder to move smoothly and autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cartridge is attached without alignment guidance, then the attachment process is simple, but the attachment and detachment resistance increases
Solution Approach 1:
The guide groove acts as an intermediary structure between the cartridge and main housing, providing alignment guidance through its upper and lower guide surfaces. This mediator ensures the memory holder moves parallel to the electrical contact surface during attachment, reducing resistance without requiring complex active control mechanisms
Solution Approach 2:
The guide groove pre-establishes the correct attachment path and orientation before the cartridge is fully attached. By providing alignment guidance in advance through its structured geometry, the system prevents misalignment issues from occurring during the attachment process, eliminating the need for corrective actions
2Ease of operation
If the memory holder is constrained to move precisely parallel to the guide surfaces, then attachment resistance is reduced, but the structural complexity increases
Solution Approach 1:
The guide groove is segmented into distinct upper and lower guide surfaces, each serving a specific function in guiding the memory holder's movement. This segmentation allows independent optimization of each surface's geometry to achieve precise alignment while keeping the overall structure simple and modular
Solution Approach 2:
Instead of constraining the memory holder directly with complex mechanical stops or guides, the invention inverts the approach by designing the guide groove surfaces to passively guide the memory holder's movement through their geometry. The memory holder's own movement creates the alignment, rather than external constraints forcing it

AI summary
A memory holder cover holds a memory holder so as to be movable with respect to the memory holder cover. An electrical contact contacts an electrical contact surface of a memory from above in a state where a cartridge is located at an attached position at which the cartridge is attached to a main housing. The main housing includes a guide groove having upper and lower guide surfaces. The upper guide surface guides movement of a memory holder from above when the cartridge is attached and detached. The lower guide surface guides movement of the memory holder from below when the cartridge is attached and detached. In a state where the cartridge is located at the attached position, the electrical contact surface is parallel to at least part of the upper guide surface or at least part of the lower guide surface.
