Liquid Ejecting Apparatus Wiping Member Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid ejecting apparatuses, such as ink jet printers, face issues where liquid drips from the wiping unit during exchange, potentially damaging the electronic mounting member, which is not adequately addressed in existing solutions.
Innovation Solution
The liquid ejecting apparatus is designed with a wiping member that is attachable and detachable, with the electronic mounting member positioned outside the attachment/detachment path, allowing for reduced risk of liquid contact during maintenance and allowing the wiping member to be movable in directions intersecting with medium transport, facilitating easy removal and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the wiping member is made detachable for easy maintenance, then ease of repair is improved, but liquid may drip on electronic components during exchange
Solution Approach 1:
The patent repositions the electronic mounting member from a location below the wiping member's attachment/detachment path to a location outside this path. This spatial reconfiguration in a different dimension eliminates the risk of liquid dripping onto electronic components during wiping member exchange, while maintaining the detachable design for ease of repair.
2Device complexity
If the electronic mounting member is positioned below the wiping member for compact design, then device complexity is reduced, but liquid damage risk increases
Solution Approach 1:
Instead of positioning the electronic mounting member below the wiping member in a vertically compact arrangement, the patent relocates it to a position outside the attachment/detachment path. This dimensional reconfiguration prioritizes protection of electronic components from liquid damage over compact vertical stacking.
3Ease of operation
If the wiping member is made movable in multiple directions for flexible cleaning, then ease of operation is improved, but removal complexity increases
Solution Approach 1:
The wiping member is designed with multi-directional movement capability, allowing it to move not only in the medium transport direction but also in directions intersecting with the medium transport. This universal movement capability enables flexible cleaning of different nozzle regions while maintaining a relatively simple detachable structure for easy removal and installation.

AI summary
A liquid ejecting apparatus includes a line head which ejects liquid from a plurality of nozzles with respect to a medium, a wiping member that is able to wipe a nozzle forming surface on which the nozzles are formed, and an electronic mounting member that governs an electronic control, in which the wiping member is attachable and detachable with respect to the liquid ejecting apparatus, and the electronic mounting member is disposed at a location which is different from below an attachment/detachment path when the wiping member is attached and detached.
