Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzle ink cartridges fail to accurately record ink consumption in real time, leading to potential damage to the nozzle circuit when the ink is depleted, as the information exchange between chips is not efficiently processed, affecting printing quality and recycling efficiency.
Innovation Solution
The design incorporates a first and second circuit substrate with interface circuits and a switching circuit, allowing for seamless signal transmission and ink amount information storage, enabling convenient replacement of the ink container and ensuring accurate ink level reporting to the printer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the ink container is integrated with the nozzle circuit into one piece, then the structure is simplified, but the ink consumption cannot be recorded in real time and the nozzle circuit cannot be recycled independently
Solution Approach 1:
The ink cartridge is divided into separate modules: the ink container (with first circuit substrate and storage circuit) and the nozzle circuit (with second circuit substrate and nozzle driving circuit) are independent components that can be separately replaced and recycled, enabling real-time ink consumption recording through the switching circuit that identifies whether the ink container is original or replaced
Solution Approach 2:
The third circuit substrate acts as an intermediary between the ink container and nozzle circuit, containing a switching circuit that processes signals from both components and determines ink consumption status, enabling real-time monitoring without direct integration of all components
2Productivity
If the ink container is replaced, then fresh ink can be supplied, but the ink amount information may not be updated correctly affecting printing quality
Solution Approach 1:
The switching circuit receives signals from both the original ink container and the replaced ink container, processes the ink amount information from both sources, and provides accurate feedback to the control circuit to determine the actual ink consumption status, ensuring printing quality is maintained after replacement
Solution Approach 2:
The switching circuit is pre-configured to identify and process signals from both original and replaced ink containers before the printing operation occurs, ensuring ink amount information is correctly updated and prepared for accurate printing control
3Ease of manufacture
If all chips are integrated into one piece, then production is simplified, but recycling cost increases and efficiency decreases
Solution Approach 1:
The circuit system is segmented into multiple independent substrates (first circuit substrate with storage circuit, second circuit substrate with nozzle driving circuit, third circuit substrate with switching circuit) that can be manufactured separately and assembled, enabling efficient recycling of individual components without requiring complete cartridge replacement
Solution Approach 2:
The design enables selective recovery and recycling of the nozzle circuit and switching circuit components while the ink container is replaced, allowing valuable electronic components to be recovered and reused, reducing recycling costs and improving environmental sustainability

AI summary
A nozzle ink cartridge, a circuit substrate, and a nozzle ink cartridge assembly are provided. The nozzle ink cartridge includes an ink cartridge main body (11), and a first circuit substrate (12) and a second circuit substrate (15) that are disposed on the ink cartridge main body (11), an accommodation portion, and a replaceable ink container (13) that is contained in the accommodation portion. The first circuit substrate (12) is configured with a nozzle circuit (122) and a first interface circuit (121) that are electrically connected to each other; the second circuit substrate (15) is configured with a second interface circuit (151) and a third interface circuit (152); and the ink container (13) is configured with a first storage circuit (142) and a fourth interface circuit (141) that are electrically connected to each other. The fourth interface circuit (141) is electrically connected to the third interface circuit (152), and the first storage circuit (142) at least stores ink amount information of the ink container. The second circuit substrate (15) is further configured with a switching circuit (154), and the switching circuit (154) is configured to be capable of processing signal transmission between the second interface circuit (151) and the third interface circuit (152). After the ink container is replaced, the ink amount information read by the printer from the nozzle cartridge can reflect ink amount of an ink container after replacement.
