Printing TRIZ Cases
- Heat Generating Element Asymmetry in Liquid Ejection Heads
Asymmetric positioning of rectangular heat generating elements prevents bubble division and cavitation damage while maintaining 1,200 dpi recording density.
- Humidity Detection in Liquid Ejecting Heads via Interlayer Resistance
A liquid ejecting head uses an interlayer with humidity-dependent resistance and detection electrodes to measure local moisture levels near the piezoelectric actuator.
- Plasma Polymerized Nozzle Plate for Stable Ink Discharge
A nozzle plate with a plasma polymerized film provides liquid repellency and controlled adhesiveness.
- Printhead Apertures for Surface Treatment Fluid Distribution
A printhead design with distinct apertures for surface treatment fluid application and ink ejection, utilizing a pressure source and controller to distribute the fluid evenly across the faceplate.
