Nested Ink Replenishing Container Prevents Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink replenishing containers for printers lack a double structure on their side surfaces, leading to ink ejection and potential damage during use, causing stains and leaks.
Innovation Solution
An ink replenishing container with a first side wall defining the ink storage portion and a second side wall outside the first, non-contacting side wall, along with a second bottom surface not in contact with the ink, to prevent volume changes and damage during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container has a single side wall structure, then the device complexity is low, but the reliability is poor because the side surface may be damaged and ink may leak
Solution Approach 1:
The patent implements a nested structure where an inner container holding ink is placed inside an outer container. The inner container has its own side wall and bottom, while the outer container provides additional protection. This nested arrangement protects the ink storage function while maintaining reasonable structural complexity.
Solution Approach 2:
The container is divided into separate functional components: an inner container for ink storage and an outer container for protection. The inner container includes a side wall and bottom defining the ink storage space, while the outer container provides additional structural support. This segmentation allows each part to fulfill specific functions independently.
2Strength
If the container has a single side wall structure, then the manufacturing is simple, but the strength is insufficient when strongly pressed causing ink ejection
Solution Approach 1:
The nested container structure provides enhanced strength against external pressing forces. When the outer container is pressed, the inner container maintains its shape and prevents ink ejection. The dual-layer structure distributes mechanical stress more effectively than a single wall.
Solution Approach 2:
The outer container acts as a protective cushion before external forces reach the inner container. This beforehand protection prevents direct transmission of pressing forces to the ink storage portion, maintaining ink volume stability during handling.
3Reliability
If the container has a single side wall structure, then the device is simple, but the reliability is poor when dropped causing side surface damage and ink leakage
Solution Approach 1:
The nested structure provides inherent protection against dropping damage. The outer container absorbs impact forces during drops, protecting the inner container and its ink contents. This structural arrangement maintains reliability without requiring additional protective packaging.
Solution Approach 2:
The outer container serves as a pre-established protective barrier against mechanical damage from drops. This beforehand cushioning structure prevents direct impact transmission to the ink storage portion, ensuring container integrity during accidental drops.

AI summary
An ink replenishing container includes a first bottom surface that defines a portion of an ink storage portion in which an ink is stored, a first side wall that intersects the first bottom surface and defines a portion of the ink storage portion, an ink outlet that communicates with the ink storage portion, and a second side wall that is disposed outside the first side wall, and that is not in contact with the ink stored in the ink storage portion.
