Liquid Cartridge Detection for Defect Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cartridge determination systems fail to accurately assess whether an ink cartridge has defects, such as missing or defective urging members, leading to potential ink leakage and image recording failures.
Innovation Solution
A liquid cartridge determination system comprising a main body with a liquid chamber, a movable member, and a resilient member, along with detectors to determine the cartridge's position and characteristics, such as defects, by detecting specific portions when the cartridge is mounted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the urging member is omitted or defective during assembly, then the ink cartridge cannot be mounted completely, but this leads to ink leakage and image recording failure
Solution Approach 1:
The detection system performs preliminary inspection of the urging member's presence and functionality before the ink cartridge is mounted to the mounting portion. The detector checks whether the movable member can move to the second position under the urging force, thereby identifying missing or defective urging members before they cause ink leakage or mounting failure.
Solution Approach 2:
The system incorporates a detector that provides feedback about the urging member's condition. When the movable member fails to reach the second position or remains locked, the detector signals a defect, allowing the system to identify and prevent problematic cartridges from being mounted, thus ensuring reliable operation.
2Ease of operation
If the operation member is deformed by impact or depressurization, then the operation member may be locked in the first or second position, but this causes ink leakage and image recording failure
Solution Approach 1:
The detection system performs preliminary inspection of the operation member's mobility before mounting. The detector checks whether the operation member can freely move between positions by applying urging force and detecting the movable member's response. This preliminary action identifies deformed operation members before they cause mounting failures or ink leakage.
Solution Approach 2:
The detector provides feedback about the operation member's operational status. When the operation member is locked or fails to move properly in response to urging force, the detector identifies this abnormal condition, allowing the system to prevent defective cartridges from being mounted and ensuring reliable operation.
3Productivity
If the ink cartridge is not mounted completely, then the assembly process is faster, but this causes ink leakage between the ink cartridge and mounting portion
Solution Approach 1:
The detection system performs preliminary verification of complete mounting before the ink cartridge is fully installed. By detecting whether the movable member reaches the second position and whether the operation member moves freely, the system identifies incomplete mounting attempts before they result in ink leakage, ensuring proper sealing while maintaining efficient assembly.

Function Achieved in This Case
The system effectively determines the presence of defects in the ink cartridge, preventing ink leakage and ensuring proper image recording by identifying incomplete or defective assemblies.
Implementation Method 1
a resilient member having a first end which is coupled to the main body and a second end which is coupled to the movable member, in which the resilient member is configured to contract to move the movable member relative to the case in the particular direction
Implementation Method 2
a first detector configured to detect the first detect portion when the liquid cartridge is positioned in a first position relative to the mounting portion, a second detector configured to detect the second detect portion when the liquid cartridge is positioned in a second position relative to the mounting portion

AI summary
A liquid cartridge determination system includes a liquid cartridge including a main body including a first detect portion. The system also includes a movable member positioned outside the liquid chamber and configured to move relative to the main body in a particular direction. The movable member includes a second detect portion. Moreover, the system includes a resilient member having a first end which is coupled to the main body and a second end which is coupled to the movable member, and a mounting portion configured to receive the liquid cartridge thereon. The system further includes a first detector configured to detect the first detect portion when the liquid cartridge is positioned in a first position relative to the mounting portion, a second detector configured to detect the second detect portion when the liquid cartridge is positioned in a second position relative to the mounting portion, and a determiner configured to determine whether the liquid cartridge has a predetermined characteristic associated therewith based on the detection of the first detect portion and the detection of the second detect portion.
