Ink Replenish Container Ribbed Abutment Prevents Front End Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink replenish containers for printers face issues with sealability and structural integrity, particularly when changing positions or during storage and manufacturing, leading to potential ink leakage and inefficiencies.
Innovation Solution
The design incorporates a container main body with a screw formation portion and an ink outlet formation member featuring a shoulder portion and abutting portions, which transmit stress along the axial direction to prevent excessive deformation and maintain sealing performance, including rib-shaped abutting portions around the circumference to ensure a closed space between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ink outlet formation member is screwed tightly to the container main body, then the sealing performance is improved, but the front end of the container main body deforms excessively
Solution Approach 1:
The abutting portion is divided into multiple rib-shaped segments distributed around the circumference. This segmentation allows stress to be distributed across multiple contact points rather than concentrated at a single point, preventing excessive deformation of the container main body while maintaining effective sealing through the combined contact of multiple ribs.
Solution Approach 2:
The shoulder portion is pre-formed on the container main body at the location where the abutting portion will contact. This preliminary structural preparation ensures that when the ink outlet formation member is screwed on, the stress is directed to this pre-designed load-bearing area, preventing deformation of the front end while achieving reliable sealing.
2Device complexity
If the screw formation portion and abutting portion are positioned closely, then the structure is compact, but the space between components may be sealed forming a closed space
Solution Approach 1:
The abutting portion is segmented into multiple ribs around the circumference, which creates gaps between the ribs and the screw formation portion. This segmentation prevents the formation of a completely closed space while maintaining structural compactness, allowing pressure equalization and preventing ink leakage through trapped air pockets.

AI summary
An ink replenish container comprises a container main body that is able to store the ink; and an ink outlet formation member, attached to a front end side of the container main body, to form an ink outlet. The container main body includes a screw formation portion having a screw for engaging with the ink outlet formation member, and a shoulder portion provided on a front end side of the screw formation portion. The ink outlet formation member includes an abutting portion that abuts the shoulder portion.
