Printing Device Wiper Extraction for Contamination-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing recording devices, the wiper for wiping ink from the recording section is positioned lower than the recording section, requiring users to insert their hand deeper into the housing for maintenance, leading to potential contamination and reduced workability.
Innovation Solution
A detachable wiper is designed to be pulled out from the housing in a direction intersecting the first direction, allowing easy access and minimizing contact with ink-stained areas, with a wiper cover that opens in the opposite direction to prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wiper is positioned lower than the recording section to face the head for wiping ink, then the wiper can effectively perform its wiping function, but the user must insert their hand deeper into the housing for maintenance, increasing the risk of touching ink-stained areas and reducing workability
Solution Approach 1:
The wiper is repositioned from a vertically lower position to a horizontally rearward position, changing the dimension of access. The wiper attached to the carriage can be pulled out in the rearward direction (second direction) intersecting the vertical direction (first direction), allowing users to access the wiper from the rear without inserting hands deep into the housing from the front, thus resolving the contradiction between effective wiping position and maintenance accessibility
2Ease of manufacture
If the wiper is disposed at a position requiring deep hand insertion into the housing for removal, then the wiper can be positioned to face the recording section, but it becomes easy to touch ink-stained portions and reduces workability
Solution Approach 1:
The wiper is designed to be detachably attached to the carriage, allowing it to be easily extracted from the housing in the rearward direction. This extraction mechanism enables users to remove the wiper without inserting hands deep into the housing, thereby eliminating the harmful factor of user contamination from ink-stained areas while maintaining the proper positioning for wiping functionality

AI summary
A printing device includes a printing section that is provided on a first direction side with respect to a medium and that performs printing and a wiper that is detachably attached inside a housing and that is configured to wipe the printing section, wherein the wiper is configured to be pulled out from the housing by being pulled out in a second direction intersecting the first direction.
