Print Head Cap Sliding Attachment for Cleaning Element Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Print heads in printing devices often require pre-installation cleaning to ensure correct functionality, but existing solutions lack ease of use and effectiveness in protecting the printing area during cleaning.
Innovation Solution
A print head cap with a cleaning element and attachment mechanism that allows for easy, user-friendly sliding attachment and removal, ensuring optimal contact with the printing area for effective cleaning without damaging the nozzles or other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a print head cap is used for pre-installation cleaning, then cleaning effectiveness is improved, but device complexity increases due to the attachment mechanism and cleaning element integration
Solution Approach 1:
The patent combines the protective cap function with the cleaning function into a single integrated component. The cleaning element is embedded within the cap structure, merging two separate functions (protection and cleaning) into one device, thereby improving cleaning effectiveness without requiring separate cleaning tools
Solution Approach 2:
The cleaning element is segmented from the cap body through an embedment structure, allowing the cleaning material to be separately replaceable or removable while maintaining the cap's protective function. This segmentation enables independent optimization of the cleaning component
2Ease of operation
If the print head cap is easily removable, then ease of operation is improved, but cleaning contact pressure decreases reducing cleaning effectiveness
Solution Approach 1:
The attachment mechanism provides dynamic adaptability, allowing the cap to be easily attached and removed when needed, while maintaining sufficient contact pressure during the cleaning operation. The mechanical connection enables controlled movement while preserving functional effectiveness
3Object-affected harmful factors
If the cleaning element is made softer for gentler cleaning, then damage to nozzles is reduced, but cleaning effectiveness decreases
Solution Approach 1:
The patent optimizes the physical parameters of the cleaning element by selecting specific material properties (softness, elasticity, friction characteristics) that balance gentleness with cleaning effectiveness. The cleaning element's parameters are tuned to provide sufficient cleaning action while protecting delicate nozzle structures
4Object-affected harmful factors
If the print head cap is used during long storage periods, then protection is improved, but cleaning element contamination increases
Solution Approach 1:
The cleaning element is designed to be extractable or removable from the cap structure, allowing it to be separated from the protective cap during storage. This extraction prevents the cleaning element from accumulating contamination while the cap continues to provide protection for the printing area

AI summary
A print head cap comprising a base element extending along a longitudinal direction and a first wall element extending along the longitudinal direction and connected to the base element. The base element comprises a cleaning element of a cleaning material on an inner side of the base element facing the first wall element. The first wall element comprises a first attachment element to removably attach the print head cap to a print head. The first attachment element allows removing the print head cap from the print head while the cleaning element remains in contact with the printing area of the print head by sliding the print head cap along the longitudinal direction, wherein the longitudinal direction is perpendicular to an ink depositing direction of the print head.
