Liquid Supply System Tank Segmentation for Level Detection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid supplying systems that rely on hydraulic head pressure to transfer liquid from a cartridge to a tank may erroneously detect the remaining liquid in the cartridge due to temporary level fluctuations in the tank, leading to incorrect assessments of the liquid's amount.
Innovation Solution
A liquid supplying system with a tank and cartridge design that includes a first storage chamber in the cartridge and a second storage chamber in the tank, where the second storage chamber has distinct portions with varying cross-sectional areas to accurately detect the liquid level using a detecting portion, minimizing erroneous detection by ensuring the liquid level in the tank is accurately reflected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor detects the liquid level in the tank to determine the remaining liquid in the cartridge, then the liquid level can be monitored, but the detection becomes erroneous when the liquid level in the tank temporarily lowers during supply to the head
Solution Approach 1:
The tank's second storage chamber is divided into three portions with different horizontal cross-sectional areas. The first portion has a smaller cross-sectional area, the second portion has a larger cross-sectional area, and the third portion has a medium cross-sectional area. This segmentation allows the liquid level to be detected at a specific position in the first portion, isolating the detection from temporary level fluctuations in other portions during liquid supply to the head.
Solution Approach 2:
Different portions of the storage chamber are assigned different cross-sectional areas to create localized liquid level response characteristics. The first portion with the smaller cross-sectional area provides a localized detection zone where liquid level changes are more pronounced and stable, enabling accurate detection while the larger portions buffer against temporary level drops during operation.
2Productivity
If the tank is used to store liquid from the cartridge, then liquid supply to the head is enabled, but temporary level drops in the tank cause erroneous detection of remaining liquid amount
Solution Approach 1:
The storage chamber is segmented into three portions with varying cross-sectional areas, allowing the system to maintain productive liquid supply while using the first portion's specific detection zone to accurately monitor remaining liquid levels despite temporary fluctuations in the larger second and third portions during active supply operations.

AI summary
A liquid supplying system includes a cartridge, a tank, and a detecting portion. The liquid stored in a first storage chamber of the cartridge is flowed into a second storage chamber of the tank through an inlet opening. The liquid stored in the second storage chamber is discharged through an outlet opening. The second storage chamber includes a first portion, a second portion, and a third portion. The second portion is positioned below the first portion and has a horizontal cross-sectional area greater than a horizontal cross-sectional area of the first portion. The third portion is positioned above the first portion and has a horizontal cross-sectional area greater than a horizontal cross-sectional area of the first portion. The outlet opening is in communication with the second portion. The detecting portion is configured to detect the level of liquid stored in the first portion.
