Liquid Ejecting Apparatus Frame Passage Hole for Tube Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid ejecting apparatuses do not allow for the detachment of the entire liquid flowing portion, including the deformable tube, from the apparatus, limiting maintenance and replacement capabilities.
Innovation Solution
A liquid ejecting apparatus with a frame that houses the liquid ejecting head and flowing portion, featuring a passage hole for the flowing portion to pass through, allowing for deformation and easy detachment of the entire liquid flowing portion by deforming the portion outside the passage hole and moving it into the frame for removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the line head is made detachable by decoupling the tube from the line head, then the line head can be accessed from outside, but the entire liquid flowing portion inclusive of the decoupled tube cannot be detached
Solution Approach 1:
The liquid flowing portion is segmented into two functional zones: a rigid portion that remains housed within the frame structure and a deformable portion that extends outward. This segmentation allows the line head to be detached through the passage hole while maintaining the ability to remove the entire liquid flowing portion when needed, resolving the contradiction between accessibility and detachability.
Solution Approach 2:
The liquid flowing portion is designed with dynamic characteristics, specifically a deformable portion that can change its configuration. When the line head needs to be detached, the deformable portion flexes to allow passage through the hole. When the entire liquid flowing portion needs to be removed, the deformable portion can be manipulated to facilitate complete detachment, providing adaptability for different maintenance scenarios.
2Adaptability or versatility
If a deformable tube is provided to supply liquid to the line head, then the liquid can be supplied flexibly, but the entire liquid flowing portion cannot be detached for maintenance
Solution Approach 1:
The liquid flowing portion is divided into a rigid supply section that maintains structural integrity for reliable liquid supply, and a deformable section that enables maintenance operations. This segmentation allows the system to benefit from both the flexibility needed for liquid supply and the detachability needed for maintenance, resolving the contradiction between adaptability and ease of repair.
Solution Approach 2:
Different portions of the liquid flowing portion are assigned different mechanical properties: the supply section has rigid properties to ensure stable liquid delivery, while the external portion has deformable properties to facilitate maintenance. This local differentiation of material or structural properties allows the system to simultaneously achieve reliable liquid supply and ease of maintenance.
3Ease of repair
If the liquid flowing portion is made detachable for complete removal, then maintenance capability is improved, but the structural complexity increases
Solution Approach 1:
The deformable portion of the liquid flowing portion is designed to dynamically adapt its shape during maintenance operations. This dynamic capability allows the entire liquid flowing portion to be detached and removed through the passage hole without requiring complex mechanical fastening or release mechanisms, thereby improving maintainability while keeping the structural complexity manageable.
Solution Approach 2:
The deformable portion utilizes flexible material properties to enable maintenance operations. The flexibility of this portion allows it to be manipulated, folded, or reconfigured during detachment and reattachment processes, providing ease of maintenance without requiring additional complex mechanical components or sophisticated release mechanisms.
