Ink Container Electrical Interface Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ink cartridges are prone to deformation and connection failure due to the displacement of the electrode in the electrical interface, especially when subjected to impact during insertion or removal.
Innovation Solution
The ink container design includes a main body with a chamber for ink storage, a supply portion for ink distribution, and an electrical interface with an electrode positioned on a fourth wall. The fourth wall features a through hole forward of the electrode, which helps disperse impact forces and prevent deformation of the electrical interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electrical interface is positioned close to the supply portion for compact design, then device complexity is reduced, but the electrode becomes vulnerable to displacement and connection failure under impact
Solution Approach 1:
The patent positions the electrical interface on the fourth wall (vertical dimension) rather than on the front wall in the horizontal plane near the supply portion. This spatial relocation to another dimension achieves compact integration while protecting the electrode from impact forces that primarily affect horizontal structures during insertion and removal operations.
Solution Approach 2:
The fourth wall acts as an intermediary structure that separates the electrical interface from direct impact paths. By positioning the electrode on this intermediate vertical surface rather than directly in the impact zone, the design mediates between compactness requirements and protection needs, allowing close integration while reducing vulnerability to displacement.
2Manufacturing precision
If the electrode is positioned forward near the supply portion for compact layout, then manufacturing precision requirements are reduced, but impact forces cause greater deformation and displacement
Solution Approach 1:
Relocating the electrical interface to the vertical fourth wall removes it from the horizontal impact trajectory. This dimensional shift allows the electrode to be positioned forward for compact layout without exposing it to the same impact forces that would cause deformation, thereby maintaining both compactness and impact resistance.
Solution Approach 2:
The fourth wall provides a localized protective environment for the electrical interface. By concentrating the electrode on this specific vertical surface away from the front impact zone, the design creates a local quality difference where the electrical interface region has enhanced protection characteristics compared to other areas of the cartridge.

AI summary
An ink container is insertable into an attachment unit. The ink container includes a main body that includes a chamber configured to store ink therein, a supply portion that extends forward from the chamber and is configured to supply the ink in the chamber to an outside of the main body; and an electrical interface that is positioned upward of the supply portion and apart from the supply portion and has an electrode.
