Ink Cartridge Chip Sequential Light Control for Location Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ink cartridge chips fail to accurately detect the location of multiple ink cartridges due to simultaneous lighting and extinguishing, leading to constant light reception by the imaging device, which prevents correct identification of cartridge positions and increases false alarm rates caused by manufacturing errors.
Innovation Solution
The proposed solution involves an ink cartridge chip with an interface unit, control unit, and storage unit that receives light control commands, executes lighting or extinguishing commands based on a state flag, and updates the flag based on association relationships between ink cartridge identification information and autogenic identification information, allowing for controlled light emission to differentiate between cartridges and prevent simultaneous light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all ink cartridge chips emit light simultaneously, then the light source is simple to control, but the light receiver cannot distinguish the location of individual ink cartridges
Solution Approach 1:
The patent divides the simultaneous light emission from multiple ink cartridges into segmented, sequential emission. Each ink cartridge chip receives a unique identification code from the controller and emits light only when its code matches the current detection sequence. This segmentation allows the light receiver to detect light from one specific ink cartridge at a time, enabling accurate location identification while maintaining simple control architecture.
2Device complexity
If conventional ink cartridge chips are used without identification codes, then the device complexity is low, but false alarm rates increase due to manufacturing errors
Solution Approach 1:
The patent implements a copying mechanism where the controller generates identification codes and transmits them to corresponding ink cartridge chips. Each chip stores and compares these codes with received detection codes. This copying approach allows the system to verify ink cartridge authenticity and location through code matching, significantly reducing false alarms from manufacturing errors while adding minimal complexity through simple code storage and comparison circuits.

AI summary
An ink cartridge chip comprises an interface unit (21), a control unit (22), and a storage unit (23). The interface unit (21) is used for receiving a light control command sent by an imaging device, the light control command comprising ink cartridge identification information. The storage unit (23) is used for storing its identification information and state flag, the state flag comprising an executable state and a non-executable state. The control unit (22) is connected to any one of light-emitting units (24) and is used for executing the light control command, a type of the light control command comprising a light lightening command or a light extinguishing command. The control unit (22) is used for: when the interface unit (21) receives a light control command, controlling, according to the light control command and the state flag in the storage unit (23), the light-emitting unit (24) to execute the light control command, and after the light-emitting unit (24) executes the light control command, re-determining a state flag according to an association relationship between the ink cartridge identification information and identification information of the control unit (22). The ink cartridge chip can detect a location of an ink cartridge in an imaging device.
