Ink Pack Drip Tray Layout for Large-Volume Leak Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ink leaks from connection points in inkjet recording apparatuses and waste liquid recovery devices are ineffective for recovering ink from large-capacity ink packs made of flexible materials.
Innovation Solution
An ink supply device with an attachment part and a drip tray is designed to accommodate an ink pack, featuring a detection mechanism to identify ink leaks and a control system to manage the process, ensuring the drip tray has a capacity equal to or larger than one ink pack and can handle tilting without overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a waste liquid recovery device is configured to suck ink from the nozzle of the inkjet head, then waste liquid from the inkjet head can be recovered, but it cannot recover ink leaked from the ink pack
Solution Approach 1:
The waste liquid recovery device is designed with a universal suction structure that can handle waste liquid from multiple sources (inkjet head nozzles and ink pack connection portions) through a single integrated system, eliminating the need for separate recovery mechanisms for different leak locations
2Reliability
If the drip tray capacity is increased to accommodate potential ink leaks from a large-capacity ink pack, then ink leakage can be contained, but the device size and complexity increase
Solution Approach 1:
The drip tray is designed with a capacity equal to or larger than one ink pack before any leakage occurs, providing sufficient buffer space to contain all potential ink from a single ink pack leak, thereby preventing ink from spreading to other components or the external environment
