Function Indicators TRIZ Cases

A conveying unit detects paper status by comparing driving torque to a reference value without extra sensors.

Common transport motor drives switching member via friction clutch to eliminate dedicated drive sources and reduce manufacturing costs.

Counter tracks discharged sheets and controller lowers productivity when threshold reached, preventing adhesion without permanent efficiency loss.

A judging unit assesses sheet dimensions before entry into a fixed conveyance opening.

Region-specific sheet detection identifies image deviations early, preventing toner fouling and maintaining high productivity.

A scanner adjusts downstream roller pressure to maintain steady transport speed.

Mechanical grippers replace suction belts to prevent substrate deformation and printhead ink depriming during high-speed printing.

Automated paddle diversion removes defective sheets from the production stream without manual intervention.

Independent rotary drives control pushing and removal devices to optimize acceleration profiles, preventing surface markings on printed products.

A laminated paddle blade with an elastic sheet and reinforcing layer draws sheets to a precise position on the processing tray.

A sheet conveyer controller measures sensor presence duration to distinguish manual sheet insertion from withdrawal events.

A sheet cassette uses a rack and pinion mechanism to automatically position the limiting member during extraction.

A reversible pressure roller drives top sheets backward to separate multi-feeds from single sheets.

A roll printer holder uses a movable holding part and displacement indicator to verify secure roll loading.

Centralized parameter management resolves setup complexity by analyzing jamming rates and automatically optimizing settings for diverse paper types.

A blowing unit creates an air layer between sheets, preventing static cohering and misalignment during stacking.

Optimizing the wrap angle ratio between 1 and 1.25 eliminates sliding and tension differences in fiber web winding without adding complex interruption devices.

A rotatable document mounting board adjusts its angle to manage pressing force on the separation member.

A circulating holding member grips recording media by reducing transport velocity before the leading end enters the holding position.

Mark points on a paperweight enable image sensors to detect paper size through optical analysis, eliminating dedicated hardware costs.
