Liquid Housing Body Filter Unit Alignment for Inkjet Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid housing bodies for inkjet printers fail to adequately suppress the inflow of foreign matter and air bubbles from the ink pack into the printing apparatus, despite efforts to stabilize printing density.
Innovation Solution
A liquid housing body design featuring a flexible bag with a built-in filter unit and spacer member, where the filter unit is positioned between the liquid lead-out member and the spacer member, aligned horizontally to prevent foreign matter and air bubbles from entering the printing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a spacer member is disposed in an ink pack to stabilize printing density, then printing density is stabilized, but foreign matter and air bubbles can still flow into the liquid ejecting apparatus
Solution Approach 1:
A filter unit is introduced as an intermediary component between the ink pack and the liquid ejecting apparatus. The filter unit includes a filter that captures foreign matter and air bubbles in the liquid, preventing them from entering the liquid ejecting apparatus while allowing the liquid to pass through. This intermediary structure resolves the contradiction by adding a protective barrier that does not interfere with the spacer member's function of stabilizing printing density.
Solution Approach 2:
The liquid housing body is segmented into distinct functional zones: the ink pack containing the spacer member for density stabilization, the filter unit for contaminant removal, and the liquid lead-out member for liquid delivery. This segmentation allows each component to perform its specific function independently, enabling the system to simultaneously stabilize printing density and prevent foreign matter inflow.
2Object-affected harmful factors
If the filter unit is disposed between the liquid lead-out member and the spacer member, then foreign matter and air bubbles are suppressed, but the structure becomes more complex
Solution Approach 1:
The filter unit is merged with the liquid housing body structure, where the filter is integrated into the housing walls or partitions. The filter unit combines the filter element with the structural framework of the liquid housing body, eliminating the need for separate complex filtering mechanisms and reducing overall structural complexity while maintaining effective foreign matter suppression.
Solution Approach 2:
The filter unit utilizes thin film structures that can be easily integrated into the liquid housing body. These flexible thin films provide effective filtration while occupying minimal space and adding minimal structural complexity to the overall design.
