Liquid Discharge Apparatus Mist Collection Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid discharge apparatuses face challenges in efficiently collecting mist generated during liquid discharge operations, leading to mist accumulation and contamination of printing media due to disturbances in airflow caused by reciprocating components, which results in sticking and dripping of mist onto the printing medium.
Innovation Solution
The apparatus incorporates a partition and suction port arrangement that forms an airflow path to efficiently guide mist towards a suction port, preventing accumulation and contamination by positioning the suction port on the side of the holder and using a gap forming member to direct airflow, while also disposing the exhaust fan and filter above the suction port to manage fiber fragments and maintain airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a filter or exhaust system is used to collect mist, then mist collection capability is improved, but airflow disturbance increases causing mist accumulation and contamination
Solution Approach 1:
The apparatus body is divided into multiple spaces by partitions. The space including the suction port is separated from other spaces, creating distinct airflow zones. This segmentation prevents airflow disturbance from propagating throughout the entire apparatus while maintaining effective mist collection in the designated zone.
Solution Approach 2:
Partition walls act as intermediaries between the suction port space and other spaces. These partitions guide airflow directionally toward the suction port while preventing turbulent flow from affecting other areas of the apparatus, thus mediating between mist collection needs and airflow stability.
2Productivity
If the suction port is positioned to effectively collect mist, then mist collection efficiency is improved, but the risk of mist sticking to the printing medium increases
Solution Approach 1:
The suction port is specifically positioned in one space separated by partitions, creating a localized mist collection zone. This local quality approach concentrates airflow and mist collection effort in a specific area away from the printing medium, maintaining high collection efficiency while preventing mist from reaching and sticking to the printing medium in other areas.
3Adaptability or versatility
If reciprocating components are used for printing operations, then printing functionality is maintained, but airflow disturbance increases leading to mist accumulation
Solution Approach 1:
The harmful airflow disturbance generated by reciprocating printing components is isolated by extracting it into a separate space defined by partitions. The suction port space is specifically designed to contain and manage this disturbed airflow, preventing it from affecting other areas where printing operations occur, thus maintaining printing functionality while controlling mist accumulation.

AI summary
A liquid discharge apparatus includes an apparatus body, a holder, a stage, an exhaust fan, a suction port, and a partition. The holder holds a target object. The stage reciprocates while holding the holder that holds the target object. The exhaust fan generates an airflow. The suction port is disposed on a side portion of the holder to suck the airflow generated by the exhaust fan. The partition partitions an interior of the apparatus body into a space including the suction port and a space not including the suction port. The partition and the holder are arranged to form an airflow path toward the suction port between the partition and the holder.
