Function Indicators TRIZ Cases

See how a reciprocating sheet-discharge member uses a holder-integrated sensor to detect retraction while avoiding contact-related breakage.

A biasing member pre-positions the stopper so gravity closes the cover fully, preventing half-open discharge and improving conveying reliability.

An acute-angle keeping unit, auxiliary rollers, and a damper stabilize linerless-label conveyance across varying sheet widths.

A two-stage reasoner selects influential paper measurements to predict color misregistration quickly and correct ink ejection timing.

A buckle-plate entry monitor detects defective sheets early and triggers downstream removal before later folding stages are disrupted.

When overlapping sheets threaten jams, timed switching routes both sheets to a third path and restores normal conveyance after the second trailing edge passes.

A single feeder unit moves between trays to retrieve media sheets, reducing feeder count, assembly complexity, maintenance, and paper jams.

Sheet-end detection lets the controller calculate media length and set each cutting position, enabling accurate equal-part cuts in a compact printer.

The control unit moves the swingable alignment paddle away from the tray as sheet count grows, preserving contact for consistent stapling.

Sheet sensors adjust the first roller’s speed during conveyance delays while the second holds its pace, stabilizing spacing and alignment.

An adjustable handle bracket and ratcheting spools roll ground-laid tarps around rods for portable, single-person storage.

Separate tray compartments and detection units verify roll and stacked-sheet placement before feeding, preventing printing errors.

A sheet sensor and speed controller adjust roller speed to restore sheet spacing, reduce jams, and protect sheets.

A sheet detector adjusts conveyor feed to match discharge timing, spacing variable-length sheets for higher stacking capacity.

Measured sheet speed sets the skew-detection threshold, reducing false stops when conveyance slows and protecting documents.

A detachable pressing member stays with the device, switching between contact and retracted states to align media and reduce jamming.

A movable roll support and height-aligned cart help position heavy, varied-width rolls for stable recording-device attachment.

During traverse cutting, the new winding core switches from speed to torque control to keep paper tension within its target range.

This case uses microphones along a transport path to locate medium jams while reducing computational load through sound-value analysis.

A sheet stacking controller lowers the stack limit for perforated sheets, reducing burr buildup and preserving alignment.

A segmented rotating cover closes the sheet-tray opening for dust control while accommodating large sheets without added footprint.

This case uses an elastically displaceable tray guide to adapt discharge angles and keep varied media stacked orderly.

This case combines a switching guide, link members, and one sensor to control paper paths and detect presence with less hardware complexity.

Downstream rollers run faster while motor-state control switches speed and torque modes to reduce vibration, power use, and media bending.

This case shows how opposed edge guides and a nested detector support sheet-width handling without enlarging the feeding tray vertically.

Guide members shift with product edge positions to prevent interference and preserve stack alignment and stability.

A determining unit extends media retention in the conveying path when sorting requires stronger curl suppression.
