Liquid Ejecting Adapter Vertical Injection Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid ejecting apparatuses, such as inkjet printers, the injecting section for replenishing ink often gets contaminated when the medium moves, causing ink to adhere and contaminate the printing surface.
Innovation Solution
The adapter is designed with an injecting section positioned below the mounting section in a vertical direction, allowing liquid to be supplied to the ejecting section without direct contact, and includes a protrusion section for increased liquid storage and secure injection, preventing contamination during movement or vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the injecting section is positioned above or near the mounting section for easy liquid injection, then the ease of operation is improved, but the medium is likely to contact the injecting section causing contamination
Solution Approach 1:
The injecting section is repositioned from a horizontal arrangement near the mounting section to a vertical arrangement below it. This dimensional change in positioning allows liquid to be injected upward into the liquid storing section without the injecting section contacting the medium on the mounting section, thus preventing contamination while maintaining operational accessibility.
2Quantity of substance
If the liquid storing section is enlarged to increase storage capacity, then the quantity of substance is improved, but the device complexity or space requirements worsen
Solution Approach 1:
The liquid storing section is extended in the vertical direction below the mounting section rather than expanding horizontally. This vertical extension increases liquid storage capacity without increasing the horizontal footprint or complicating the overall device structure, as the injecting section naturally connects to this vertically extended storage space.
3Ease of operation
If the injecting section is disposed outside the housing section for accessibility, then the ease of operation is improved, but the reliability worsens due to increased spillage risk
Solution Approach 1:
The adapter serves as an intermediary component that houses the injecting section and connects it to the liquid storing section. This intermediary structure provides a contained environment for liquid injection, preventing spills while maintaining external accessibility. The adapter acts as a bridge between the housing section and the externally accessible injecting section, ensuring liquid is contained during injection.

AI summary
A liquid ejecting apparatus includes: a mounting section that is capable of moving in a state of mounting a medium; a liquid ejecting section that is capable of ejecting a liquid onto the medium mounted on the mounting section; and an adapter that has an injecting section capable of injecting the liquid and an outlet section capable of flowing the liquid out to the liquid ejecting section, in which the injecting section of the adapter is disposed below the mounting section in a vertical direction.
