Paper-Making TRIZ Cases

Retractable walls fold inward to flatten the packing box, reducing storage space while maintaining structural stability during stacking.

Foldable extension flaps adjust package depth from compact shipping to retail display configuration.

Leading and trailing lugs with opposing recesses capture and fold octagonal carton blanks, resolving shape accuracy issues in high-speed packaging lines.

Suction cups guide major flaps against a plow to eliminate gaps, ensuring square sealing without overlaps.

Controlling the transverse to longitudinal crease stiffness ratio prevents carton distortion and paper jams during high-speed packaging operations.

A carton blank uses exterior stacking tabs and partial through-handles to maintain structural integrity while preserving smooth interior surfaces.

A polygonal container blank uses exterior reinforcing panels to boost stacking strength while keeping the interior surface flat.

Composite cardboard construction with deformed seams provides structural integrity for lightweight burial containers without heavy materials.

Nested handle mechanism eliminates separate component assembly, resolving stacking inefficiency and recycling labor in multi-layered basket designs.

Notched bottom flaps with adhesive portions enable automatic folding without external hooks, reducing machine stoppages during high-speed processing.

An opaque extensor inserted within a web loop provides a consistent optical target, eliminating false detections from transparent materials.
