Printing TRIZ Cases

A multi-function device uses an enhancement printhead to deposit fluid on specific pixels, increasing contrast ratios without requiring expensive substrates.

Interlocking absorbent segments increase contact area for rapid liquid flow while preventing leakage at the connection interface.

Guard drops separate adjacent nozzle streams to eliminate crosstalk while dynamic charging maintains drop separation accuracy across varying media speeds.

Internal vertical deformation replaces external levers to retain the ink cartridge, preserving storage volume while ensuring stable electrical connections.

Lossy discrete cosine transform compresses color look up table data while corrective information restores accuracy to reduce memory consumption.

Rotating holder moves ink cartridge between laid and standing positions to mix sedimented pigment, preventing mouthpiece damage from repeated detachment cycles.

A printhead maintenance station uses air blasting and a microfiber dabbing device to clean ink from the ejection face.

An epoxy resin composition with a thixotropic agent and photobase generator enables rapid UV curing.

Segmented line head groups adjust print resolution and processing speed by varying nozzle counts per color group.

Amorphous alumina barrier prevents lead diffusion along grain boundaries while maintaining high crystal orientation and dielectric reliability.

Detecting light-emitting member position relative to a rod lens array using optical intensity distribution.

Segmenting the detection system separates the sensor from the liquid container, reducing contamination risk and cartridge cost.

A printer controller updates maintenance evaluation indices based on post-service ejection performance data.

Vertical electrode pins in a liquid chamber detect remaining fluid volume via conductivity, preventing erroneous readings during high-flow discharge operations.

A piezoelectric element uses a stepped first electrode to support uniform liquid phase deposition of an orientation control layer.

A maintenance cap encloses an inkjet print head nozzle in cleaning liquid to maintain a wet state.

A flow restrictor limits negative pressure in an ink delivery system to maintain fluid integrity.

A discharge line removes bubbles from the main line to maintain uniform flow rates across multiple ink jet heads.

Inclined spittoon surface guides print fluid into waste receptacle via gravity, preventing nozzle clogging and aerosol generation.

A waste liquid absorber with a density gradient resolves the trade-off between permeability and retention, preventing leakage while minimizing tank size.

A displacement mechanism adjusts contact depth on a flexible tube terminal end to control waste liquid flow cross-section.

Concave section on cartridge upper surface guides lever regulating section into mounting groove, preventing accidental removal without increasing device volume.

A controller adjusts feed rates from multiple ink tanks into a mixer, reducing density variations when switching between different manufacturing lots.
