Paper Ink Container Geometry for Complete Refill Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink containers made from plastic materials pose environmental burdens, and substituting them with paper materials requires effective methods to ensure thorough use of ink before disposal, as containers made from paper materials need to be reused or disposed of, such as by burning, without obstructing ink flow.
Innovation Solution
An ink container and refill system using a paper material with an impermeable inner layer and specific geometric configurations to ensure smooth ink flow towards the outlet, satisfying relational expressions for cross-sectional areas, allowing complete ink usage.

Engineering Contradiction Analysis
1Object-affected harmful factors
If plastic materials are substituted with paper materials for ink containers, then environmental burden is reduced, but ink flow may be obstructed
Solution Approach 1:
The ink container uses a composite structure combining paper material with an ink-impermeable coating layer. The paper material reduces environmental burden while the coating layer prevents ink obstruction, resolving the contradiction between eco-friendliness and functional reliability.
Solution Approach 2:
The invention changes the surface properties of the paper material by applying an ink-impermeable coating, transforming it from a potentially ink-obstructing material into one that maintains smooth ink flow. This parameter change (surface impermeability) allows paper to replace plastic without sacrificing ink flow performance.
2Ease of manufacture
If paper materials are used for ink containers, then recyclability is improved, but ink usage completeness deteriorates
Solution Approach 1:
The composite structure of paper material with ink-impermeable coating enables both recyclability (from paper) and complete ink usage (from the coating that prevents surface obstruction), allowing the container to meet both sustainability and functional requirements.
Solution Approach 2:
The ink-impermeable coating is applied locally to the inner surface of the paper container, providing the specific property needed for complete ink extraction only where ink contact occurs, while the rest of the paper container maintains its recyclable properties.
3Ease of manufacture
If conventional bottle-shaped articles are used, then manufacturing is simplified, but ink extraction efficiency deteriorates
Solution Approach 1:
The invention modifies the geometric parameters of the conventional bottle shape by defining specific cross-sectional area relationships (S1, S2, S3, D1, D2) that optimize ink flow toward the outlet. This maintains manufacturing simplicity while dramatically improving ink extraction efficiency through optimized geometry.
Solution Approach 2:
The invention addresses ink extraction efficiency not by changing the basic bottle shape, but by optimizing the dimensional relationships between different cross-sectional areas along the container height, using geometric parameter optimization to improve flow dynamics without complicating manufacturing.
