Print Head Movable Portions for Capping Path Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink jet printing devices face interruptions during printing operations due to the presence of functional components like cap mechanisms and maintenance mechanisms, which are typically positioned outside the printing area to avoid interference but can still hinder the print head's movement.
Innovation Solution
The design incorporates a mobile print head with a two-axis moving mechanism and functional components such as a cap mechanism and maintenance mechanism, which have movable portions that engage outside the printing area, allowing them to transition into functional states without interrupting the printing process by using first and second contact members to move into position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional components are arranged outside the printing area, then they do not interrupt the print head during printing, but they increase device complexity and reduce compactness
Solution Approach 1:
The functional components are designed with movable portions that can dynamically change position between a standby state (within drawing area) and a function exercised state (outside drawing area). This dynamic repositioning allows the device to maintain compactness while ensuring printing operations are not interrupted.
Solution Approach 2:
The functional components are divided into stationary portions and movable portions. The movable portions can be positioned independently to either interrupt the print head path during maintenance operations or clear the path during printing operations, resolving the contradiction between needing access and needing clear path.
2Device complexity
If functional components are positioned within the drawing area, then device compactness is improved, but they may interrupt the print head during printing operations
Solution Approach 1:
The functional components utilize movable portions that can transition between positions within the drawing area (for compactness) and positions outside the drawing area (to avoid interruption). This dynamic positioning capability allows the system to achieve both compactness and operational reliability.
3Device complexity
If functional components use fixed positions, then device structure is simpler, but moving paths for capping and maintenance are longer
Solution Approach 1:
The functional components are designed with movable portions that can dynamically reposition themselves based on operational requirements. During maintenance operations, the movable portions position themselves optimally within the drawing area to minimize movement paths, while maintaining a relatively simple overall device structure.
4Productivity
If functional components are arranged to minimize moving paths, then maintenance efficiency is improved, but device structure becomes more complex
Solution Approach 1:
The functional components are segmented into stationary portions (providing structural support) and movable portions (providing operational flexibility). This segmentation allows the movable portions to be positioned for optimal maintenance efficiency while the stationary portions maintain structural simplicity.
Solution Approach 2:
The movable portions can dynamically position themselves to optimize maintenance operations, reducing moving paths and improving efficiency, while the overall device structure remains relatively simple due to the stationary portions providing stable mounting.

AI summary
An electronic apparatus includes a mobile object, a moving mechanism, and a functional mechanism. The mobile object has a first contact member and performs a moving operation within a drawing area and a set drawing operation on a drawing medium. The moving mechanism moves the mobile object. The functional mechanism has a portion located within the drawing area and takes a standby state and a function exercised state in which a set function is exercised. The functional mechanism includes a movable portion having a second contact member. In an abutting state where the first contact member and the second contact member come into contact with each other outside the drawing area, the mobile object moves along a movable direction of the movable portion so that the movable portion moves to bring the functional mechanism into the function exercised state.
