Printer Ink Receiver Design for Gap Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers with image capturing units and supporting members experience ink adhesion and penetration issues, leading to adverse effects such as ink reaching regions below the image capturing section, which can cause operational disruptions and damage.
Innovation Solution
A printing apparatus design that includes a supporting member, a printing section, an image capturing section, and a receiver. The image capturing section is integrated into the supporting member with a gap, and the receiver is positioned below this gap to collect any ink that adheres and penetrates, with additional absorbers and trays on the outer wall of the lens barrel to guide and hold the ink, reducing the risk of ink flowing to lower regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the image capturing section is integrated into the supporting member with a gap, then the image capturing unit can be positioned to capture images of the medium, but liquid may penetrate through the gap to regions below the supporting member
Solution Approach 1:
A receiver is introduced as an intermediary component between the gap and the region below the supporting member. The receiver receives liquid that penetrates through the gap, preventing it from reaching regions below the image capturing section. This mediator structure resolves the contradiction by allowing the gap to remain open for image capturing while intercepting harmful liquid flow.
Solution Approach 2:
The receiver converts the harmful effect of liquid penetration into a controlled collection function. By positioning the receiver to receive liquid flowing through the gap, the system transforms the potential damage into a manageable liquid collection mechanism, where the liquid is captured and contained rather than allowed to cause harm to electronic components.
2Reliability
If the receiver is disposed below the gap to receive liquid, then liquid penetration is mitigated, but the device structure becomes more complex
Solution Approach 1:
The receiver serves multiple functions: it acts as a liquid collection device, a protective barrier for electronic components, and a structural element that can be integrated into the existing supporting member design. By making the receiver multi-functional, the added complexity is justified by the multiple benefits it provides, including liquid reception, protection, and potential integration with other system components.
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
The solution effectively mitigates ink-related issues by ensuring ink is collected and contained within the receiver, preventing it from reaching lower areas and minimizing operational disruptions, thus enhancing the reliability of the printing process.
Implementation Method 1
The receiver includes an absorber configured to absorb the liquid
Implementation Method 2
The liquid, which has entered the gap, is likely to flow downward along the outer wall of the lens barrel
Implementation Method 3
The liquid, which has entered the gap, is likely to flow downward along the outer wall of the lens barrel
