Waste Liquid Drainage Layout for Liquid Discharge Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face the issue of waste liquid dripping from maintenance portions leaking outside the apparatus, posing a risk of contamination.
Innovation Solution
The apparatus incorporates a reception portion positioned below the maintenance portion to collect waste liquid, with a communication path guiding the liquid into a waste liquid flow path, ensuring containment within the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a maintenance portion is added to perform maintenance of the liquid discharge portion, then the liquid discharge apparatus can maintain the nozzle surface, but waste liquid may drip from the maintenance portion and leak outside the apparatus
Solution Approach 1:
The patent extracts the waste liquid drainage function from the maintenance portion by providing a separate drainage path that leads waste liquid away from the liquid discharge portion. This separation prevents waste liquid from contaminating the liquid discharge apparatus while maintaining the maintenance capability.
Solution Approach 2:
The patent introduces a drainage path as an intermediary element between the maintenance portion and the external environment. This intermediary channel guides waste liquid away from critical components, preventing direct contact between waste liquid and the liquid discharge portion while maintaining maintenance access.
2Object-affected harmful factors
If waste liquid is collected in a reception portion, then waste liquid can be contained, but the apparatus structure becomes more complex
Solution Approach 1:
The patent merges the reception portion with the existing drainage path structure. Instead of adding a completely separate collection system, the design integrates waste liquid reception into the drainage infrastructure, containing waste liquid while minimizing additional structural complexity.
Solution Approach 2:
The patent implements a nested structure where the reception portion is positioned within or alongside existing apparatus components. The drainage path is routed through available spaces, and the reception portion utilizes the drainage infrastructure, creating a compact integrated system that contains waste liquid without significantly increasing overall apparatus complexity.

Function Achieved in This Case
Effectively prevents waste liquid from leaking outside the apparatus by directing it into a controlled flow path, maintaining cleanliness and preventing contamination.
Implementation Method 1
a reception portion arranged on a lower side than the maintenance portion in a vertical direction and configured to receive waste liquid dripping from the maintenance portion

AI summary
A liquid discharge apparatus includes a liquid discharge portion configured to discharge liquid, a maintenance portion that performs maintenance of the liquid discharge portion, a reception portion arranged on a lower side than the maintenance portion in a vertical direction and configured to receive waste liquid dripping from the maintenance portion, and a waste liquid flow path through which the waste liquid flows. The liquid discharge portion includes a nozzle configured to discharge the liquid in a discharge direction intersecting with the vertical direction. The reception portion includes a communication path that guides the received waste liquid to the waste liquid flow path. The communication path is provided at a lower portion of the reception portion.
