Inking Apparatus TRIZ Cases

Engaging and engaged portions secure the sealing member on a vertical mounting surface, improving assembly and reducing leakage risk.

A valve closes the communication port during nozzle-face cleaning, preventing chamber contamination and ink or paint dilution.

This case uses dual holding units and fixation members to limit heater-induced head base warpage and preserve ink placement.

This recording head varies standby potential across elements to correct dot-size variation and improve image density uniformity.

A transport motor shifts from hold to short brake during cutting to reduce power use and prevent sheet deviation.

Temperature estimates for each ink flow path adjust nozzle drive voltage, compensating for viscosity changes across conditions.

Oscillating cantilevers mix print fluid to prevent sedimentation and nozzle failures.

Different flow-path lengths and earlier drive timing align pressure waves, improving ejection efficiency for viscous inks.

Flexure-coupled actuators provide compact printhead translation and rotation for precise registration without locking mechanisms.

This case sequences minute nozzle vibration before circulation to limit thickening and preserve liquid ejection performance.

This liquid jet head uses perpendicular fixation and heat radiation to cool drive devices while reducing stress on terminal couplings.

This case uses a second flow passage member with Young's modulus of 65 GPa or less to limit spread and preserve sealability.

Expanding portions connect mismatched supply-port pitches in one channel member, reducing parts and supporting liquid circulation.

Selective moisture protection preserves piezoelectric actuator vibration displacement.

A segmented support mechanism separates rotation and axial movement to expand thermal head travel and enable easy replacement.

A blowing unit directs air toward the recording heads, limiting ink mist entry through gaps and reducing internal adhesion.

Stacked flow substrates use elongated slit cross sections to stabilize fluid resistance and improve high-speed ink ejection.

A locally thickened bottom wall reinforces the damper chamber, easing stress concentration while preserving pressure fluctuation damping.

Adjacent jetting rows and shared manifolds limit drying and sedimentation while reducing laminate count in the printhead.

Dry-etched liquid channels use a slower-etching protection film to limit roughness, contamination, bubbles, and film peeling.

Inclined contacts stabilize inkjet head module adjustment and reduce positioning rattle.

Adjust discharge by surface height and inclination to keep curved-surface ink films uniform.

Conductive channel integration stabilizes grounding and limits noise in liquid ejection heads.

Microcirculation and macrocirculation replace concentrated ink with fresh liquid, improving ejection speed and accuracy.

Multiple nozzle arrays can stress nozzle bonds; segmented, thickness-extending couplings support flatness and consistent discharge.

A taller individual supply flow path and aligned chamber wall circulate liquid, limiting viscosity rise during long ejection halts.

Noncontact chamber walls reduce seal wear while maintaining controlled roller fluid flow.

Oxygen plasma activates tantalum oxide for Ta—O—Si bonding, preserving ink resistance and sliding resistance over time.

An enlarged, inclined supply flow path guides air bubbles toward the circulation pump, stabilizing ink ejection without enlarging the head.

This case uses plasma emission monitoring to precisely etch protection film, maintaining membrane integrity and consistent displacement.

A PDC OVJP depositor aligns delivery and exhaust flows to improve material use, resolution, and feature uniformity across fly heights.

This printing casing protects an installed apparatus during line cleaning while its cleaning portion enables printhead cleaning.
