Flexible-Bag Liquid Container With Variable-Length Outlet Pipes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid containers with separate gas absorbers from the supply port allow the gas absorber to move freely, leading to occluded areas and unused liquid around the absorber when the liquid is consumed.
Innovation Solution
A liquid container design with a bag, liquid outlet member, and gas absorption unit, featuring differently lengthed liquid outlet pipes and a gas transmission film to ensure even liquid distribution and absorption, preventing residual liquid near the gas absorber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gas absorber is provided separately from the supply port, then the gas absorber can freely move within the liquid container, but occluded areas occur and liquid around the gas absorber is not consumed and left
Solution Approach 1:
The liquid outlet pipes are segmented into multiple pipes with different lengths, allowing liquid to be discharged from multiple locations within the bag. This segmentation ensures that liquid can be effectively removed even when the gas absorber moves to different positions, preventing occluded areas and residual liquid accumulation.
Solution Approach 2:
Different liquid outlet pipes have different lengths to provide localized liquid discharge capabilities at various positions within the bag. This local quality adjustment ensures that regardless of where the gas absorber moves, there are always adequate liquid discharge paths available, preventing liquid accumulation around the gas absorber.
2Ease of operation
If the gas absorber is provided separately from the supply port, then the gas absorber can freely move within the liquid container, but occluded areas occur in the liquid container
Solution Approach 1:
The liquid outlet system is divided into multiple pipes of varying lengths, creating multiple discharge zones throughout the bag. This segmentation ensures continuous and reliable liquid consumption efficiency regardless of gas absorber position, eliminating occluded areas that would otherwise reduce reliability.
Solution Approach 2:
The liquid outlet pipes extend into the bag along its length, adding a spatial dimension to liquid discharge. This dimensional approach ensures that liquid can be removed from multiple locations simultaneously, maintaining reliable liquid consumption efficiency even when the gas absorber moves freely in three-dimensional space.

AI summary
A liquid container includes: a bag having flexibility configured to store liquid inside; a liquid outlet member mounted on one end of the bag and having a liquid outlet section to discharge the liquid to a liquid ejecting apparatus; a gas absorption unit movably disposed in the bag and having (i) a space holding member that forms an internal space of the gas absorption unit, and (ii) a gas transmission film that defines an inside of the internal space and an outside with the internal space decompressed to a pressure lower than an atmospheric pressure; and a plurality of liquid outlet pipes coupled to the liquid outlet section and disposed in the bag, the plurality of liquid outlet pipes having an inlet, which are configured to allow the liquid introduced from the inlet to flow to the liquid outlet section. Lengths of the plurality of liquid outlet pipes are different.
