Fluid Containing Member With Linked Separation Films
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid containing members in ink jet printers and imprint apparatuses face delays in detecting separation film breakage and potential fluid mixture due to equal internal pressures in containing chambers, leading to fluid deterioration.
Innovation Solution
The fluid containing member employs two separation films that are partly connected or in contact with each other, allowing them to move together with changes in internal pressure, thereby maintaining equal pressures in the chambers and preventing fluid mixture even if one film breaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single separation film is used to divide two containing chambers, then the structure is simple, but the detection of film breakage is delayed and fluid mixture occurs when internal pressures are equal
Solution Approach 1:
The single separation film is divided into two separate films (first separation film and second separation film) that are positioned on opposite sides of the interface between the two containing chambers. Each film is independently supported by its own supporting member, creating a segmented barrier system that prevents fluid mixture while maintaining structural simplicity.
Solution Approach 2:
Supporting members are introduced as intermediary elements between the separation films and the containing chambers. These supporting members maintain the separation films in a state that allows them to move with pressure changes while preventing direct contact between the films and the chamber walls, thereby enabling reliable fluid separation without compromising structural integrity.
2Reliability
If the internal pressures of the two containing chambers are equal, then fluid contact is minimized, but detection of separation film breakage is delayed
Solution Approach 1:
The patent employs a detection mechanism that monitors the positions of the first and second separation films. When a separation film breaks, the position of the remaining film changes due to pressure differential, providing immediate feedback that enables rapid detection of the breakage event without requiring fluid mixing or stagnation.
Solution Approach 2:
The separation films are designed to be movable rather than fixed, allowing them to dynamically respond to pressure changes within the containing chambers. This dynamic behavior enables the films to move together in response to pressure variations, maintaining fluid separation while allowing for rapid detection of breakage through position monitoring.
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
This solution effectively suppresses the mixture of fluids in the containing chambers by maintaining equal internal pressures and allowing for smooth movement of the separation films, thus preventing fluid contact and deterioration.
Implementation Method 1
The first separation film and the second separation film are partly connected to each other or partly contact each other so as to move together in accordance with a change in an internal pressure of the first containing chamber or an internal pressure of the second containing chamber

AI summary
A fluid containing member includes a first containing chamber that contains a first fluid, and a second containing chamber that contains a second fluid. The first containing chamber and the second containing chamber are separated from each other by a first separation film on a side of the first containing chamber and a second separation film on a side of the second containing chamber. The first separation film and the second separation film are partly connected to each other or partly contact each other so as to move together in accordance with a change in an internal pressure of the first containing chamber or an internal pressure of the second containing chamber.
