Ink Container Handle Design for Outlet Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid containers and supply apparatuses for inkjet printers face difficulties in attaching and detaching the liquid inlet part from the liquid outlet part due to the obscured location of the connection point, making it hard to see and handle.
Innovation Solution
A liquid container design with a handle part that positions the liquid outlet part on the opposite side, allowing it to be easily visible and accessible when the container is hung, and includes a flow channel in the leg part to increase the liquid capacity and prevent dust accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection part is located on the lower side of the ink bag, then the liquid container can maintain a stable structure, but the connection part becomes difficult to see and attach/detach
Solution Approach 1:
The patent inverts the conventional location of the connection part from the lower side to the upper side of the liquid container. This inversion makes the connection part visible and easily accessible when the container is hung vertically, directly resolving the visibility and accessibility issues while maintaining structural stability through the handle design.
2Ease of operation
If the connection part is located on the lower side of the ink bag, then the structure is simple, but it is difficult to attach and detach the liquid inlet part
Solution Approach 1:
The patent merges the connection part with the handle structure, integrating the outlet into the handle rather than treating it as a separate component. This integration maintains structural simplicity while improving operability, as the handle naturally positions the connection part at the upper end for easy access.
3Ease of operation
If the liquid outlet part is located on the upper side, then visibility and accessibility are improved, but the structure becomes more complex
Solution Approach 1:
The handle structure serves multiple functions: it provides grip for the user, positions the outlet at the upper end for visibility and accessibility, and integrates the outlet connection functionality. This multi-functionality approach avoids adding separate components, thereby improving operability without significantly increasing structural complexity.

AI summary
An ink container that is attachable to and detachable from a liquid supply apparatus that supplies ink to a liquid injection apparatus. The ink container includes: an ink container part that houses ink; a handle unit that is located at an end of the ink container part; and an ink outlet part that is provided on the handle unit and that is in communication with an inside of the ink container part via the handle unit. The ink outlet part is located on a portion of the handle unit that is on an opposite side to the ink container part side.
