Movable Discharge Port for Liquid Ejection Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may accidentally stain their hands when attaching or detaching the waste liquid holding container in existing liquid ejection apparatus configurations due to the proximity of the discharge port.
Innovation Solution
A movable discharge portion is integrated into the liquid ejection apparatus, allowing it to retract above the introduction port when the cover is open, preventing direct contact with the discharge port during container attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the discharge portion is positioned to face the introduction port for efficient liquid discharge, then the liquid discharge function is improved, but the user's hand may be stained when attaching or detaching the waste liquid holding container
Solution Approach 1:
The discharge portion is configured to be movable between a first position (retracted) and a second position (extended). When the waste liquid holding container is detached, the discharge portion moves to the first position away from the introduction port, preventing hand contamination. When the container is mounted, the discharge portion moves to the second position to face the introduction port, ensuring efficient liquid discharge.
2Productivity
If the discharge port is positioned close to the introduction port for direct liquid discharge, then the liquid transfer efficiency is improved, but the accessibility of the discharge port increases causing potential contamination
Solution Approach 1:
The discharge portion with the discharge port is made movable between two positions. In the extended position (second position), the discharge port is close to the introduction port for efficient liquid transfer. In the retracted position (first position), the discharge port is moved away from the introduction port, reducing accessibility and preventing contamination during container attachment/detachment.

AI summary
A liquid ejection apparatus that prevents a user's hand from becoming dirty when attaching and detaching a liquid holding container, the liquid ejection apparatus includes a space portion that is open on a side surface of a housing, a liquid holding container that is detachably mounted to the space portion and includes an introduction port for introducing liquid to an inside thereof, on an upper surface, and a discharge portion that is provided at a position facing the introduction port inside the space portion in a state in which the liquid holding container mounted and includes a discharge port for discharging the liquid to the inside of the liquid holding container, in which the discharge portion is configured such that at least the discharge port is movable.
