Power Drive Mechanisms TRIZ Cases
- Inkjet Head Unit With Replaceable, Precisely Aligned Recording Head
A framed inkjet head uses paired adjusting screws to replace failed recording heads without replacing the full assembly.
- Recording Head Mounting Member for Water-Repellent Ink Guidance
This case shows how a water-repellent head mounting member with recesses and protrusions limits ink buildup during wiping.
- Inkjet Printhead Nest Assembly for Accurate Front Access
A detachable nest separates printhead replacement from precision mounting while shielding electronics from ink mist.
- Distance-Sensed Head Positioning for Stable Liquid Discharge
A distance detector and lifter adapt liquid discharge head height to medium thickness, stabilizing discharge and protecting the head.
- Liquid Ejection Device with Below-Coupling Drip Containment
A below-coupling reception unit contains liquid drips during mounting-unit removal, reducing peripheral contamination.
- Image-Forming Device Calibration Using Self-Printed Reference Patterns
Calibrate sensor and nozzle alignment from printed reference images, removing external markers and reducing detection uncertainty.
- Liquid Ejection Capping Device with Top-Entry Cap Attachment
A guided cap moves vertically for top-side attachment, reducing operator burden and interference with the liquid ejection head.
- Liquid Droplet Ejection Detection via Dual-Distance Measurements
Electric-current timing at two electrode distances measures droplet speed and bending, improving ejection-failure detection accuracy.
- Printing Carriage Colorimetric Feedback for Test-Free Color Adjustment
During carriage printing, density feedback corrects print data after each pass, reducing media use and color-adjustment time.
- Compact Inkjet Printing Unit with Nested Aerosol Extraction
A chassis-integrated extraction unit captures aerosol around movable print modules while preserving a compact footprint for web systems.
- Liquid-Ejecting Supply-Flow Closure Detection During Carriage Motion
A contact-based detector identifies a closed supply flow path after transport, helping prevent printing failures and user errors.
- Printhead Conveyor Tape for Condensate Removal During Printing
A slotted conveyor tape carries condensate away from the printhead, reducing print-quality problems and maintenance interruptions.
- Step-Compensating Carriage Printer With Sensor-Based Jetplate Correction
Sensors and adjustable jetplate motors compensate for media skew and beam deformation, reducing conveyor precision demands.
