Packaging TRIZ Cases

A baling guide system channels ties through a chamber wall to enable single-position tying.

A package bag uses a self-supporting stable portion and a pouring path to guide liquid packing material through an easy-peelable seal.

A carousel conveyor transfers opening devices along an arc-shaped path to a rotating drum, reducing inertial stress and shock forces during aseptic application.

Segmented forming heads coordinate suction and slurry flow to eliminate batch idle time, ensuring uniform wall thickness across the product.

Perimetric welding of the straw prevents leakage along the outer surface, resolving complexity and spill risks in existing designs.

A hopper extending portion engages a guide surface on the supporting body to enable precise mechanical alignment during assembly.

A fifth encoder wheel and laser rangefinder compensate for urethane wheel deformation and steel wheel slip, ensuring accurate positioning.

Folded transparent plastic bags secured by stickers reduce shelf space while maintaining product visibility.

Perforating common edges on sealable films enables easy separation while maintaining structural integrity during manufacturing.

A film packing device uses a quick-release unit to mount different film application units for rapid roll replacement.

Segmented augers with a flexible joint elevate granular material while minimizing leakage and belt wear.

Outward folding prevents deformation and jamming while ensuring adequate sealing integrity.

Applicator assembly feeds polymer string through magazine and separator to form plug, eliminating complex alignment mechanisms.

An elastomer retainer cooperates with support indents to hold items securely while reducing material waste and simplifying consumer opening.

Asymmetric transverse incisions in a semi-rigid sheet enable vertical opening, solving unpredictable product flow from horizontal V-folds.

A feeding unit uses a feed screw device to advance sealed semi-finished packs containing pourable products.

A suction transfer part holds articles in an inclined state to enable stable high-speed movement.

A transport device uses curved guides to connect linear paths, enabling smooth 180-degree deflection of container carriers.

Cam-driven load arms slide within guide slots to accommodate diverse tote dimensions, resolving adaptability versus complexity trade-offs.

Segmented carriers and dedicated braking rails eliminate forward bouncing, ensuring precise synchronization with folding units.

A resilient plunger skirt transforms between unexpanded and expanded states to position container elements accurately.

Force amplification via a gear and knee lever reduces actuator stress while maintaining holding force.
