Ink Cartridge Rib Structure for Leak-Safe Port Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The risk of ink leakage due to damage to the liquid supply port and positional deviation during cartridge mounting in printing systems, leading to erroneous mounting and potential ink leakage.
Innovation Solution
A cartridge design with a rib formed at the bottom wall to protect the liquid supply section and a printing system with a liquid introduction section that includes a rib to prevent damage and ensure proper alignment during mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cartridge is handled without protective structures, then the handling process is simple, but the liquid supply port is vulnerable to damage from external impacts causing ink leakage
Solution Approach 1:
The rib is formed in advance on the bottom wall during cartridge manufacturing, creating a protective structure before the cartridge is put into use. This preliminary structural preparation ensures that the liquid supply port area is protected from external impacts during handling and mounting operations
Solution Approach 2:
The rib acts as a cushioning or buffer structure that absorbs external impacts before they can reach and damage the liquid supply port. When the cartridge is dropped or subjected to external forces, the rib provides structural reinforcement and protection to the vulnerable liquid supply port area
2Reliability
If no positioning features are provided on the cartridge, then the cartridge structure is simpler, but positional deviation occurs during mounting causing erroneous mounting and potential ink leakage
Solution Approach 1:
The rib is positioned asymmetrically on the bottom wall of the cartridge, creating a unique geometric feature that enables one-way or directional mounting. This asymmetric structure ensures that the cartridge can only be mounted in the correct orientation, preventing erroneous mounting while maintaining relatively simple overall structure
Solution Approach 2:
The rib is pre-formed on the cartridge bottom wall to provide positioning functionality before the mounting operation occurs. This preliminary structural feature guides the cartridge into the correct position during the mounting process, ensuring accurate alignment with the cartridge holder

AI summary
A cartridge mounted on a cartridge mounting section of a printing device having a liquid introduction section for receiving a liquid, the cartridge includes a liquid accommodating section configured to accommodate the liquid, a bottom wall on which a liquid supply section that is coupled to the liquid introduction section and supplies the liquid is disposed, and a rib formed at the bottom wall.
