Inkjet Printer Partitioning Wall Blocks Platform Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet printers with a placement platform that moves in the secondary scanning direction often have a gap between the platform and the inner wall, allowing large articles to accidentally enter the movement space and interfere with the printer's operation.
Innovation Solution
The design incorporates a partitioning wall positioned to the side of the placement platform, extending in the secondary scanning direction and vertical direction, which blocks the gap and prevents large articles from entering the movement space when the platform is at its downstream position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the placement platform is positioned at the downstream end of its movement range, then the gap between the placement platform and the inner wall is opened, but this allows articles to accidentally enter the movement space and interfere with operation
Solution Approach 1:
The inner wall is segmented into two parts: the supporting wall that extends in the primary scanning direction and the partitioning wall that extends in the secondary scanning direction. This segmentation creates a blocked gap that prevents article entry while maintaining structural support for the guide rail.
Solution Approach 2:
The partitioning wall acts as an intermediary element between the supporting wall and the placement platform. It blocks the gap formed when the platform is at the downstream end, preventing articles from entering the movement space while allowing the platform to move freely.
2Reliability
If the partitioning wall is added to block the gap, then article entry is prevented, but the device complexity increases
Solution Approach 1:
The partitioning wall is merged with the supporting wall to form an integrated inner wall structure. This combining approach prevents article entry without requiring separate, additional components, thereby minimizing the increase in device complexity.
Solution Approach 2:
The partitioning wall serves multiple functions: it blocks the gap to prevent article entry, maintains the structural integrity of the inner wall, and does not interfere with the movement of the placement platform or the carriage. This multi-functionality reduces the need for additional components.

AI summary
A printer can comprise a supporting wall that extends in a primary scanning direction, a table that is positioned lower than the supporting wall and that is structured so as to be able to move in a secondary scanning direction, a guide rail equipped on the supporting wall that extends in the primary scanning direction, a head carriage that is provided slidably on the guide rail and that can move in the primary scanning direction, an ink head mounted on the head carriage, and a partitioning wall that is positioned lower than the supporting wall and to a side of the table in the primary scanning direction and that extends in the secondary scanning direction and the vertical direction. When the table is positioned at the maximally downstream position along the secondary scanning direction, the upstream end portion of the table is positioned further downstream of the supporting wall and further upstream than the downstream end portion of the partitioning wall.
