Printing TRIZ Cases

A cleaning tank and suction path draw solvent vapor away during print head drying, reducing nearby vapor and ink stains.

An elastic seal closes the container opening before insertion, then enlarges its communication hole to supply ink without leakage.

Anisotropic conductive film and thermocompression bonding lower resin protrusion in COF thermal print heads, reducing paper-jam risk.

A protruding flow-path pipe redirects adhesive-shrinkage stress, preserving liquid-tight coupling and limiting fixing-plate deformation that can affect droplet landing.

A piezoelectric module sends ultrasonic vibration through the dispensing nozzle to reduce clogging during high-viscosity printing.

Local fixation of at least 60% of the outer peripheral region limits wrinkles while preserving pressure absorption in a liquid ejecting head.

Front, rear, and extension wall portions shield ultraviolet-curable ink pouches from light while a simpler housing lowers manufacturing cost.

Separate discharge paths and a switching member target the affected chamber, reducing liquid waste during air-bubble removal.

Ribs and surface patterns distinguish refillable from non-refillable ink tanks, while valve and air-release features limit leakage.

Abnormal-nozzle detection switches between full, compensating, and lower-resolution modes to limit white streaks while simplifying control.

Uneven passage distances can trap bubbles during cleaning; differentiated outflow resistance improves discharge and reduces waste ink.

Clustered refresh dots keep inkjet nozzles jetting reliably while using fewer dots, reducing spit-pattern visibility and print artifacts.

A swingable lid exposes the ink absorber for simpler replacement, while magnetic closure and lid detection help prevent opening during printing.

An enclosing frame seal protects multiple piezoelectric elements while reducing seal area, thermal stress, and charge accumulation.

Merging the heating resistance and conductive layers removes stress-concentrating steps, improving inkjet chip strength, reliability, and yield.

Separate covers for the ink and air chambers expose bonding gaps during leak checks, preserving air-chamber function and preventing ink leakage.

Excess adhesive is routed through cavity-plate grooves and vent holes, protecting the pressurizing chamber during actuator bonding.

Printer maintenance uses weaker suction beneath the nozzle face and stronger suction at the side faces to remove ink without collapsing the meniscus.

A detachable valve holder separates the spring-loaded sealing assembly from the ink container, supporting leak prevention, cleaning, and reuse.

Limited absorber volume causes frequent replacements; a supported ink absorber with a bent downward extension increases capacity without widening the holder.

A non-ejecting drive signal lets piezoelectric elements reveal filled pressure chambers through vibration frequency, reducing unnecessary ink-filling time.

A charging unit and accelerating electrode guide ink droplets to display substrates, reducing placement errors from trajectory drift.

A positive-pressure-first sequence fills the head before the negative-pressure pump starts, limiting air bubbles during liquid circulation.

Separate collection chambers keep ink and pre-processing liquids from mixing and aggregating, supporting reliable ejection and easier maintenance.

Blended printing profiles apply high-ink rules to skin tones and ink-saving rules elsewhere, preserving image quality while reducing ink use.

Recess and positioning parts constrain cartridge movement in multiple directions, aligning the chip and ink outlet for smooth mounting.

A slide member closes the ink passage before detachment while a check valve blocks backflow, preventing residual ink from soiling hands and equipment.

A projection member captures free liquid around the atmosphere path opening, preventing blockage and stabilizing cartridge supply.

During deep reactive ion etching, an oversized electrode dissipates charge to ground, improving chamber accuracy and discharge stability.

Shifted nozzle arrays raise control-data volume for high-resolution printing; segmented buffers and alternating acquisition reduce memory needs.
