Ink Container Lid Layout for Bubble Exhaust and Viscosity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet recording devices face issues with ink quality deterioration due to bubble ingress into the recording head, leading to ejection errors and image quality degradation.
Innovation Solution
A liquid container design with strategically positioned openings on an imaginary circle, including an ink flow inlet, outlets, and a bubble exhaust port, promotes efficient ink stirring and bubble removal, preventing their entry into the recording head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid container uses a conventional single opening design, then the structure is simple, but bubbles and high viscosity ink enter the recording head causing ejection errors
Solution Approach 1:
The liquid container is divided into multiple functional openings: a first opening for ink supply, a second opening for bubble discharge, and a third opening for high viscosity ink discharge. This segmentation allows each opening to handle specific functions, preventing bubbles and problematic ink from reaching the recording head while maintaining overall system reliability.
2Duration of action of stationary object
If the liquid container stores ink for extended periods, then ink quality deteriorates due to bubble accumulation, but frequent ink replacement increases operational complexity
Solution Approach 1:
The bubble discharge opening specifically extracts and removes bubbles from the ink storage region, while the high viscosity ink discharge opening removes deteriorated ink. This extraction mechanism allows the liquid container to maintain ink quality consistency over extended storage periods without requiring frequent replacement, thereby improving both storage duration and reliability.
3Reliability
If the liquid container uses multiple openings for bubble and high viscosity ink discharge, then ink quality is maintained, but the manufacturing complexity increases
Solution Approach 1:
The lid portion serves as a multi-functional component that integrates multiple openings (first, second, and third openings) with different functions. This universal design allows a single component to handle ink supply, bubble discharge, and high viscosity ink discharge, maintaining image formation consistency while simplifying the overall manufacturing process compared to using separate components for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents ink ejection errors by maintaining ink quality, ensuring consistent image formation by minimizing bubble and high viscosity ink entry into the recording head.
Implementation Method 1
The lid portion has a plurality of openings, which include a liquid flow inlet configured to allow the liquid to flow into the containing region, and a liquid flow outlet configured to allow the liquid to flow out from the containing region
Implementation Method 2
When viewed in the up and down direction, the plurality of openings are disposed on an imaginary circle whose center is a center of the containing region, with equal intervals

AI summary
A liquid container includes a main body portion having a bottom part and a side wall part, so as to store liquid in a containing region enclosed by the bottom part and the side wall part, and a lid portion that covers the containing region from above. The lid portion has a plurality of openings, which include a liquid flow inlet configured to allow the liquid to flow into the containing region, and a liquid flow outlet configured to allow the liquid to flow out from the containing region to a feed destination. When viewed in the up and down direction, the plurality of openings are disposed on an imaginary circle whose center is a center of the containing region, with equal intervals.
