Liquid Cartridge Cover Structure for Tap Alignment Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid storing cartridges and printers face the risk of the liquid container tap floating or rising upward, leading to potential misalignment with the ink supplying needle and possible ink leakage.
Innovation Solution
A liquid storing cartridge design with a cover that has contact parts to stabilize the tap position by making contact with the tap, ensuring it remains aligned with the supply needle, reducing the likelihood of upward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid container is accommodated in the opening of the case, then the tap can be inserted into the tap supporting part, but the tap may float or rise upward causing misalignment with the supplying needle
Solution Approach 1:
The cover acts as an intermediary element between the liquid container and the external environment. It provides contact parts that directly engage with the tap to prevent upward movement, while still allowing the liquid container to be properly accommodated in the case opening.
Solution Approach 2:
The cover's contact parts automatically engage with the tap when the liquid container is placed in the case, providing self-positioning and stabilization without requiring additional active control mechanisms or complex assembly steps.
2Reliability
If the tap is not stabilized, then the structure remains simple, but the supplying needle may not enter the tap satisfactorily causing ink leakage
Solution Approach 1:
The cover serves as a mediating structure that introduces minimal complexity by adding only contact parts to stabilize the tap, without requiring complex locking mechanisms or multiple components.
Solution Approach 2:
Instead of making the entire cartridge structure more complex, the stabilization feature is localized to specific contact parts on the cover that engage only with the tap, leaving the rest of the structure simple.

AI summary
There is provided a liquid storing cartridge for accommodating a liquid container which has a tap. The liquid storing cartridge includes: a case having an opening and a first sidewall; and a cover which is configured to cover at least part of the opening, and which has a second sidewall, the first and second sidewalls defining a sidewall of the liquid storing cartridge in a state that the at least part of the opening is covered by the cover. The first sidewall is configured to support the tap in a state that the liquid container is accommodated in the opening. The cover further has a contact part provided on the second sidewall. The contact part is configured to make contact with the tap in the state that the liquid container is accommodated in the opening and that the at least part of the opening is covered by the cover.
