Regenerated Chip Signal Segmentation for Ink Cartridge Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for regenerated ink cartridges result in poor printing quality due to the disruption of data signal communication between the printer and the original ink cartridge, affecting essential functions like print spot selection.
Innovation Solution
A method and structure for a regenerated chip that electrically connects to both the printer and the ink cartridge chip, allowing for selective control of data signal communication based on operation commands and feedback voltages, ensuring accurate communication and data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the DATA signal wire is stopped to communicate with the original ink cartridge chip, then the regenerated chip can be directly connected to the printer for data reading, but other important functions such as print spot selection are affected and printing quality deteriorates
Solution Approach 1:
The patent segments the DATA signal wire function into two separate signal wires: one dedicated to data reading between printer and regenerated chip, and another for transmitting control signals (such as print spot selection) to the ink cartridge chip. This segmentation allows independent operation of data reading and control functions, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent introduces an intermediary control mechanism that manages the connection between printer, regenerated chip, and original ink cartridge chip. This intermediary ensures that control signals are properly routed through the regenerated chip to the original chip, maintaining essential functions while enabling regenerated chip data access.
2Adaptability or versatility
If the DATA signal communication between printer and original ink cartridge chip is stopped, then the regenerated chip can be directly connected to the printer, but the number of signal wires increases and device complexity increases
Solution Approach 1:
The regenerated chip is designed with multi-functionality, serving both as a data storage interface and as a signal transmission medium. It can read data from itself and simultaneously relay control signals to the original ink cartridge chip, reducing the need for separate dedicated wires and simplifying the overall connection architecture.

AI summary
A method for controlling a regenerated chip, a regenerated chip, and a regenerated ink cartridge are provided. The regenerated chip is electrically connected to a printer by means of a first data signal wire and a logic signal wire, and is electrically connected to an ink cartridge chip by means of a second data signal wire. The method for controlling a regenerated chip includes: detecting an operation command sent by the printer by means of the first data signal wire and the logic signal wire; and when it is detected that the operation command is not a selected operation command, sending a data signal to the ink cartridge chip by means of the second data signal wire, wherein the data signal instructs the ink cartridge chip to communicate with the printer.
