Ink Tank Adapter Segmentation for Pressure Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inkjet recording apparatuses face issues with ink cartridge deformation due to pressure differentials when enclosed in gas-impermeable packaging bags, leading to permanent deformation and potential ink quality issues from dissolved gases.
Innovation Solution
A container arrangement featuring an ink tank with a rigid frame and a separate adapter, where the ink tank is enclosed in a packaging bag under reduced pressure, while the adapter is outside the bag, maintaining ink deaeration and preventing cartridge deformation by distributing pressure forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ink cartridge is enclosed in a gas-impermeable packaging bag under reduced pressure, then the ink quality is maintained (deaerated state), but the ink cartridge may deform due to pressure differential
Solution Approach 1:
The ink cartridge is divided into two separate parts: the ink tank (which remains under reduced pressure inside the packaging bag) and the adapter (which is positioned outside the packaging bag at atmospheric pressure). This segmentation allows each part to experience appropriate pressure conditions, preventing deformation while maintaining ink quality.
Solution Approach 2:
The adapter is extracted from the packaging bag, separating it from the ink tank. By removing the adapter from the reduced-pressure environment, it avoids the pressure differential that would cause deformation, while the ink tank remains protected inside the bag.
2Strength
If the rigidity of the ink cartridge is increased to prevent bending, then deformation is reduced, but the complexity of the device increases
Solution Approach 1:
Instead of increasing the rigidity of the entire ink cartridge, the design segments the cartridge into an ink tank and adapter, allowing the softer ink tank to remain protected under reduced pressure while the adapter operates independently outside the bag, avoiding the need for enhanced structural rigidity throughout.
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 cartridge deformation and maintains ink quality by ensuring the ink tank remains under controlled pressure conditions, even when exposed to atmospheric pressure, thereby ensuring consistent ink ejection and extending the cartridge's lifespan.
Implementation Method 1
The pressure of an interior of the packaging bag is less than a pressure of an exterior of the packaging bag

AI summary
A container arrangement includes a packaging arrangement including an ink tank defining an ink chamber therein, in which the ink chamber is configured to store ink therein, and a packaging bag enclosing the ink tank therein. A pressure of an interior of the packaging bag is less than a pressure of an exterior of the packaging bag. The container arrangement also includes an adapter configured to be coupled to the ink tank, and a container enclosing each of the packaging arrangement and the adapter. The adapter is positioned outside the packaging bag.
