Liquid Introduction Pipe with Multi-Height Ports for Storage Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid storage bodies for liquid ejection apparatuses face inefficiencies in liquid supply due to incomplete introduction of liquid from shrunk storage bags, leading to insufficient discharge to the apparatus.
Innovation Solution
A liquid storage body design featuring a liquid introduction pipe with multiple introduction ports at different heights, a convergence portion, and a flow channel to ensure uniform density distribution and prevent void formation during shrinkage, enhancing the close-touch performance and reducing unused liquid volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single pipe is used to discharge liquid from the storage bag, then the structure is simple, but the liquid cannot be sufficiently supplied to the liquid ejection apparatus
Solution Approach 1:
The liquid introduction pipe is divided into multiple introduction ports positioned at different heights within the storage bag. This segmentation allows liquid to be introduced from multiple locations simultaneously, improving supply efficiency without requiring multiple separate pipes throughout the system.
Solution Approach 2:
Multiple liquid introduction ports are merged into a single liquid introduction pipe structure that includes a convergence portion. This combines the functionality of multiple pipes into one integrated component, improving liquid supply while maintaining structural simplicity.
2Quantity of substance
If the liquid storage bag is shrunk during use, then liquid is consumed, but liquid remains in the shrunk bag and cannot be sufficiently supplied
Solution Approach 1:
The liquid introduction pipe extends vertically through different heights of the storage bag, utilizing the vertical dimension to reach liquid that would otherwise remain trapped in shrunk portions of the bag. This ensures complete liquid extraction even as the bag shrinks during use.
3Stability of the object's composition
If liquid containing precipitation components is stored, then the liquid can be supplied to the apparatus, but the density becomes unstable
Solution Approach 1:
The liquid introduction system is segmented into multiple ports at different heights, allowing liquid to be drawn from various vertical positions within the storage bag. This helps obtain a more representative sample of the liquid composition and maintain density stability despite precipitation.
Solution Approach 2:
The system utilizes the vertical position parameter (height) as a variable to draw liquid from different levels. By introducing liquid from multiple heights, the system compensates for density variations caused by precipitation and maintains stable composition.
