Liquid Container Atmosphere Chamber Segmentation for Ink Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid containers, such as those used in inkjet printers, face challenges in minimizing ink leakage through the atmosphere communicating port, which is not adequately addressed by previous configurations.
Innovation Solution
The liquid container design incorporates multiple atmosphere chambers oriented in different directions and a waterproof air-permeable member to prevent ink from entering the atmosphere communicating portion, ensuring that ink does not leak out through the atmosphere opening port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single atmosphere communicating portion is used, then the structure is simple, but liquid leakage cannot be effectively prevented
Solution Approach 1:
The atmosphere communicating portion is divided into multiple independent atmosphere chambers (first atmosphere chamber and second atmosphere chamber) that are spatially separated and oriented in different directions. This segmentation prevents liquid from progressing through the entire communicating portion, as liquid entering one chamber cannot easily reach the other chamber due to their opposite orientations and the liquid inlet port positioning.
2Ease of operation
If the atmosphere opening port is positioned to facilitate liquid supply, then liquid inlet is improved, but liquid leakage risk increases
Solution Approach 1:
The liquid inlet port is specifically positioned to receive liquid injection from a direction opposite to the first atmosphere chamber. This local quality assignment creates an asymmetric configuration where the liquid inlet area is optimized for easy liquid supply while the opposite-facing atmosphere chambers create barriers that prevent liquid leakage paths.

Function Achieved in This Case
This configuration effectively prevents ink leakage from the liquid container by preventing the progression of ink between chambers and utilizing a waterproof air-permeable member to block ink entry into the atmosphere communicating portion, maintaining the internal pressure and reducing ink loss.
Implementation Method 1
a waterproof air-permeable member arranged in an atmosphere chamber that is closest to the atmosphere opening port

AI summary
Leakage of liquid from a liquid container is reduced. A liquid container capable of containing liquid has: a liquid containing portion capable of containing the liquid; a liquid inlet port receiving injection of the liquid into the liquid containing portion; an atmosphere opening port communicating with the liquid containing portion and introducing atmosphere into the liquid containing portion; an atmosphere communicating portion leading to the liquid containing portion from the atmosphere opening port; a first face oriented outward; and a second face oriented outward in a direction that is different from a direction of the first face. The atmosphere communicating portion includes a plurality of atmosphere chambers, and the plurality of atmosphere chambers include a first atmosphere chamber provided in the first face, and a second atmosphere chamber provided in the second face.
