Liquid Discharge Cover Venting for Ink Mist Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in effectively managing ink mist circulation and ventilation while maintaining airtightness during maintenance and operation, particularly when covers are opened and closed, which interferes with ventilation channel formation.
Innovation Solution
The apparatus incorporates a first and second ventilation channel formation components that connect seamlessly when the cover is closed, allowing airflow to circulate ink mist and cool electrical components without interference, using slanted or elastic ends to ensure airtightness and efficient ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is opened to expose the liquid discharge unit for maintenance, then ease of operation is improved, but airtightness deteriorates
Solution Approach 1:
The ventilation channel is divided into two separate formation components: one in the apparatus body and one in the cover. These segments connect only when the cover is closed, allowing the system to maintain ventilation functionality while achieving airtightness during operation and ease of access during maintenance.
Solution Approach 2:
The ventilation channel configuration changes dynamically based on cover position. When closed, the channels connect to provide ventilation and collect ink mist. When opened, the channels disconnect to maintain airtightness while allowing maintenance access. This dynamic reconfiguration resolves the contradiction between operational accessibility and airtightness.
2Object-generated harmful factors
If the ventilation channel is formed to collect ink mist, then harmful factors are reduced, but device complexity increases
Solution Approach 1:
The ventilation channel formation components serve multiple functions: they provide ventilation pathways for air circulation, collect ink mist generated during liquid discharge, and automatically connect/disconnect based on cover position. By integrating these functions into the existing cover and apparatus body structures, the solution reduces harmful factors without significantly increasing device complexity.

AI summary
A liquid discharge apparatus includes an apparatus body, a liquid discharge unit, a first ventilation channel a cover, and a second ventilation channel. The liquid discharge unit discharges a liquid. The first ventilation channel in the apparatus body has a first end opened to an interior of the apparatus body in a first direction. The cover is movable between an open position and a closed position to operably close the apparatus body. The second ventilation channel connected to the cover has a second end opened to the interior of the apparatus body in a second direction different from the first direction. The cover at the closed position causes the first end of the first ventilation channel to be connected to the second end of the second ventilation channel.
