Inkjet Transport Path Dynamics for Unobstructed Cover Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transportation path in existing ink jet recording apparatuses with upward and downward sections at the same level can interfere when uncovered, preventing the path from being fully opened.
Innovation Solution
A transportation apparatus with a cover that moves path formation portions to different positions, allowing the path to be uncovered without interference by using a movement portion that adjusts the first path formation portion's position based on the cover's opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the transportation path includes downward and upward sections at the same level to increase path length without increasing apparatus size, then the transportation path length is improved, but the components interfere with each other when the transportation path is uncovered
Solution Approach 1:
The first path formation portion is made movable between a first position (defining downward path) and a second position (away from downward path) in response to cover opening/closing operations. This dynamic repositioning allows the transportation path to be uncovered without component interference, resolving the contradiction between path length and ease of operation.
2Device complexity
If the first path formation portion remains stationary in the movement area of the second path formation portion, then the apparatus structure is simplified, but the cover cannot be opened due to component interference
Solution Approach 1:
The first path formation portion is configured to move in response to cover opening/closing operations, transitioning between a first position (defining downward path during closed state) and a second position (away from downward path during opened state). This dynamic adjustment enables cover opening while maintaining structural integration, resolving the contradiction between device complexity and ease of operation.

AI summary
A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.
