Detachable Valve Holder for Ink Refill Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink refill containers face difficulties in removing and reusing the valve at the ink outlet, making it challenging to efficiently refill ink tanks.
Innovation Solution
An ink refill container design featuring a valve member urged by a spring member, housed in a valve holder with an engagement portion that allows detachable attachment to the container body, facilitating easy removal and reuse of the valve unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve is provided at the ink outlet to control ink flow, then ink leakage is prevented, but the valve becomes difficult to remove and reuse
Solution Approach 1:
The ink refill container is divided into separable components: the container body and the valve holder assembly. The valve holder containing the valve member can be detached from the container body, enabling easy removal and reuse of the valve components while maintaining reliable sealing when assembled. This segmentation resolves the contradiction by allowing the valve to be both functional and removable.
Solution Approach 2:
The engagement portion provides a detachable connection mechanism between the valve holder and container body. This dynamic connection allows the valve assembly to be easily attached and detached multiple times, transforming the valve from a fixed, non-reremovable component to a dynamically reconfigurable one that maintains sealing reliability while enabling reuse.
2Ease of operation
If the valve holder includes an engagement portion for detachable attachment, then ease of removal is improved, but device complexity increases
Solution Approach 1:
The engagement portion is designed as a simple, localized feature on the valve holder that interfaces with a corresponding feature on the container body. This segmented approach adds minimal structural elements only where needed for detachment, avoiding overall system complexity while enabling easy removal functionality.
Solution Approach 2:
The engagement portion is extracted as a distinct, simple mechanical feature rather than integrating complex locking or sealing mechanisms. This extraction principle keeps the added complexity minimal while achieving the primary goal of easy removal and reattachment.

AI summary
An ink refill container includes: a container body portion; an ink-outlet forming portion coupled to the container body portion and including a cylindrical portion having an ink outlet; a sealing member provided in the cylindrical portion and having an opening that enables insertion and removal of an ink introduction conduit; a valve member provided to be configured to come into contact with the sealing member; a spring member configured to urge the valve member toward the sealing member; and a valve holder holding at least the valve member and the spring member, and the valve holder includes an engagement portion configured to detachably engage at least one of the ink-outlet forming portion and the container body portion.
