Wrapper Twisting/Gathering TRIZ Cases

Reduced coil cross-sections concentrate magnetic flux at corners and overlaps, resolving uneven heating without increasing device complexity.

A forming guide shapes moving webs into pleats to maintain equal path length across the width.

A non-metal guide part constrains the ultrasonic cutting knife movement within a packaging machine to prevent mechanical interference.

Adjustable rollers align heavy cartons on a conveyor belt, eliminating manual handling errors during automated adhesive application.

A sealing station adjusts gassing pressure by discharging gas into a collection volume to maintain consistent packaging appearance.

A high-speed vertical film wrapping machine employs orbitally-reciprocating sealing heads to join shrink-wrap tubes around upright products.

Modulated vacuum and cooling air prevent low-softening films from melting or tearing during packaging.

A sealing body uses a ceramic carrier with vertical through-contacts to integrate heating conductors and sensors for precise thermal control.

A pre-impregnated felt substrate applies high smoke point oils to prevent food sticking and drying out during high-temperature cooking.

Pre-formed sheet lids eliminate on-site film cutting, reducing material waste and dust contamination while simplifying the sealing device configuration.

Grasping the bag during closure enables precise application of a folded element, resolving contradictions between productivity and device complexity.

A packing apparatus adjusts roller pressure via timing sensing to affix sealing tape on cardboard boxes.

A heat-sealing apparatus uses a planar motor conveyor plane to move magnetic shuttles carrying supporting elements.

Homogeneous sealing strips eliminate metal clips in tubular packages, resolving the trade-off between load-bearing capacity and recyclability.

A storage electric sealer uses a sliding plate and press bar to retract components into a compact cuboid form.

Mechanical plunger engagement with top flaps determines box height, eliminating expensive optical sensors and preventing jamming from protruding packaging.
