Remanufactured Ink Cartridge Electronic Patch with Exposed Programming Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing remanufacturing processes for ink cartridges are complex and inconvenient, particularly when updating data in electronic patches, as they often require pre-programming before installation and can lead to electrical short circuits, and the process is not flexible for different models or upgrades.
Innovation Solution
A remanufactured ink cartridge design featuring an electronic patch with exposed programming terminals that can be installed between the original chip and ink accommodation container, allowing for data repair or upgrade without pre-programming, and with a staggered or larger substrate configuration to reduce short circuit risks and facilitate easy alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electronic patch is pre-programmed before installation, then the data can be updated, but the process becomes complex and inconvenient
Solution Approach 1:
The electronic patch is designed with exposed programming terminals that allow data to be programmed directly into the patch after installation but before the ink cartridge is sealed. This eliminates the need for complex pre-programming processes while maintaining the ability to update data efficiently.
Solution Approach 2:
The electronic patch is separated from the main ink cartridge body, allowing it to be installed independently. This segmentation enables the patch to be programmed separately without complicating the overall remanufacturing process, as the patch can be updated without handling the entire cartridge assembly.
2Volume of moving object
If the electronic patch is installed between the original chip and ink accommodation container, then the structure is compact, but electrical short circuits may occur
Solution Approach 1:
The electronic patch uses a larger substrate with exposed programming terminals at specific locations. This local quality design ensures that the terminals are positioned to avoid electrical short circuits while maintaining compact overall structure. The exposed terminals are strategically placed to prevent contact with conductive elements that could cause short circuits.
3Ease of operation
If the programming terminals are exposed outside the original chip, then data can be programmed without removing the patch, but the alignment precision requirement increases
Solution Approach 1:
The electronic patch extends in a dimension beyond the original chip boundary, with programming terminals exposed at the edge. This dimensional extension allows programming terminals to be accessible from the outside without requiring precise alignment during installation, as the terminals are positioned at the periphery where they can be accessed independently of the chip's internal geometry.
