Ink-jet Printing Module With Segmented Cartridge Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional page-width array ink-jet printers require replacing the entire printing platen when an ink-jet chip is damaged, are costly due to complex ink channel systems, and have complicated manufacturing processes for mounting and circuit layout.
Innovation Solution
The ink-jet printing module features a page-width array platen with independently detachable and replaceable ink-jet cartridges, each with its own receiving cavity, control node circuits on the vertical sidewalls, allowing for easy assembly, ink filling, and cartridge changing, reducing manufacturing complexity and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the plurality of ink jet chips are arranged on the bottom of the carry mechanism of the printing platen, then the printing process can be performed directly on the paper which is passed under the nozzle array, but if one of the ink-jet chips is damaged, the whole printing platen has to be changed
Solution Approach 1:
The printing platen is divided into multiple independent receiving cavities, each capable of holding a separate ink-jet cartridge. This segmentation allows individual cartridges to be replaced without affecting the entire printing platen, resolving the contradiction between maintaining high printing efficiency and enabling easy cartridge replacement when a chip is damaged.
2Reliability
If a complicated ink channel system is provided to transport ink to each ink chamber, then ink can be supplied to all ink-jet chips, but the cost for design and manufacture will be increased
Solution Approach 1:
The ink channel system is extracted from the central printing platen and integrated directly into each individual ink-jet cartridge. This allows ink to be supplied reliably to each ink-jet chip while simplifying the overall system design and reducing manufacturing costs, as each cartridge becomes a self-contained unit with its own ink supply.
3Ease of manufacture
If the ink-jet chips have to be mounted on the bottom of the carry mechanism one by one, then the page-width array platen can be manufactured, but the circuit layout must be arranged and controlled in a complicated way and need complicated manufacturing process
Solution Approach 1:
The circuit layout complexity is segmented by integrating control electronics directly into each ink-jet cartridge rather than requiring complex wiring across the entire printing platen. This allows individual cartridges to be manufactured and tested independently, then assembled into the printing platen, greatly simplifying the manufacturing process and circuit arrangement.
4Reliability
If the whole printing platen has to be changed when one of the ink-jet chips is damaged, then printing quality can be maintained, but the cost and time for replacement will be increased
Solution Approach 1:
The printing platen is segmented into multiple independent receiving cavities that can hold separate ink-jet cartridges. When one chip is damaged, only the specific cartridge containing that chip needs to be replaced, not the entire platen. This maintains printing quality through consistent cartridge design while dramatically reducing replacement time and cost.

AI summary
An ink-jet printing module is used for a page-width array ink-jet printer. The ink jet printing module includes a page-width array platen and a plurality of ink-jet cartridges. The page-width array platen has a plurality of receiving cavities arranged as an array. Each of the ink-jet cartridges is detachably and independently embedded into one of the receiving cavities, and includes a body for storing ink, an ink-jet chip to be driven for ejecting the ink, a plurality of nozzles disposed on the ink-jet chip, and a control node for receiving signal to drive the ink-jet chip. The ink-jet chip is disposed on a bottom of the page-width array platen and is driven to eject the ink through the nozzles onto a printing medium.
