Typewriters TRIZ Cases

A turnable flap guides sheets through a recording path while a biasing member presses the sheet against a platen.

A nail drawing apparatus detects surface height distribution to define a drawable area for precise ink deposition.

A printer voice portal uses a telephony interface to receive user voice commands, eliminating complex IP address entry on telephone keypads.

Printer monitors battery voltage to adjust print head energy delivery, maintaining consistent print quality as power source depletes.

Comparing actual height profile signals against earlier reference profiles enables reliable detection of substrate malfunctions without fixed references.

A mobile printer measures skin curvature and color to adjust ink discharge and image tone before deposition.

Independent suction zones prevent ink diversion from airflow, ensuring precise droplet placement and reducing energy consumption.

A second driving roller provides conveying force without nipping the recording medium, enabling effective skew correction in curved paths.

Dual nozzle arrays eject liquid onto workpiece regions using variable ejection cycles matched to surface inclination angles.

An automated arm positions a portable printer to apply labels on multiple substrate surfaces, eliminating the need for separate devices.

A light absorbent shielding panel minimizes stray UV reflection, preventing ink curing on print heads and extending component lifespan.

A nail printer uses a fingerprint sensor to detect finger position and shifts the placement table for precise alignment.

Automatic calibration eliminates manual parameter configuration errors by transmitting pre-determined settings from a central server to the printer.

A near field coupler generates localized electromagnetic concentrations to communicate exclusively with a single UHF transponder.

An adhesive carrier layer extends beyond the printable template perimeter, allowing edge-to-edge inkjet printing without plastic sealing margins.

A printing apparatus incorporates a non-adhesive member at the discharge port to manage linerless label handling.

Visualizing vacuum zones on the job editor ensures media fixation and image quality.

A pressing unit compresses tube-shaped print media against a heated metal member, eliminating air gaps that reduce heat transfer efficiency.

Integrated spring mechanism feeds sheets from storage to portable printer, reducing device volume and weight.

A drying unit generates a gas flow in the space between the print medium and table to remove water vapor.

Axial nozzle arrays on a rotating drum enable continuous tube printing, while an integrated groove mount secures garments to eliminate seam discontinuities.

Oblique gas blowing and opposing suction enable non-contact fabric transport, preventing image quality deterioration caused by mechanical nipping deformation.

An electrostatic charging mechanism tacks sheet media to a dielectric belt, preventing air current distortion during high-speed multi-head printing.

A 3D printing model predicts movement paths and parameters to apply macroscopic and microscopic corrections during direct container printing.

Preheating coated media with an auxiliary dryer reduces surface tension to prevent intercolor bleed and puddling while maintaining color richness.

A controller switches registration control modes to adjust web velocity measurements based on operational conditions.

Varying key protrusion heights isolate power and print buttons from character inputs, preventing unintended shutdowns or premature printing.

A pixel definition layer with differentiated barrier wall heights controls inkjet-printed solution flow across OLED substrates.

A vacuum platen assembly draws textile substrates against a support surface using adjustable pneumatic pressure to secure the material during printing operations.

Rotating scan rollers enable vertical positioning between lines, resolving the trade-off between horizontal scanning ease and multi-line productivity.

A recording apparatus uses a switchback path to reverse conveyance direction for simultaneous media drying.
