Bags Opening TRIZ Cases

Automated bag movement and blade cutting open bulk bags over a hopper to speed discharge, reduce operator exposure, and limit contamination.

A rolling disk knife and counter element cut bags cleanly for sterile container discharge while reducing blade wear and worker handling.

Patients with limited dexterity can use a front finger groove and rear funnel to capture urine and route it by gravity.

Clamping isolates bag contents during end-flap cutting, while overpressure limits particle ingress during pharmaceutical container transfer.

Preliminary gas inflation stabilizes vacuum-packed outer packaging before cutting, limiting deformation and adhesion for precise sterile-object removal.

Linear feeding and a textured roller cut, pull, and squeeze pouches to extract liquid while reducing direct blade handling and safety risks.

Perpendicular cutting and paired grippers automate article-array debagging, reducing manual handling, labor, and article damage.

This case uses automated cutters, rollers, and sieves to open defective pouches and recover nicotine powder for reuse.

Replacing mechanical tearing elements, the device uses pressurized fluid jets to open sacks of varying sizes while eliminating wear and safety risks.

Rotating draining means stretch and circulate flexible bags through traction mechanisms, extracting trapped fluids while avoiding complex hydraulic systems.

Serpentine-shaped agitating elements enable simultaneous linear and circular movements to empty bags completely while reducing energy consumption.

Radial blades cut lifted outer bags while pneumatic positioning prevents inner bag damage during automated removal.

Segmenting the foil into a cut-off access area and an attached residual bag prevents interference with suction elements during object extraction.

Modular spike star wheels assembly eliminates contamination risks by removing mechanical components from the bag slitting chamber.

A driven feed chain frame synchronizes with a transport chain to move sliced products, preventing sagging or wrinkling across varying thicknesses.

A clamping device with movable jaws grips the zipper slider to automate closure.

Angled circular blades slice sacks into a sinusoidal pattern to open containers for powder discharge.

A vacuum chamber expands internal gas to unfold packaging flaps, preventing collapse during pressure equalization.
