Paper/Cardboard Articles TRIZ Cases

A paper crumpling machine uses curved tines and an electromagnetic brake to guide sheeting and control roll speed without heavy mechanical components.

Expanded layered cores create lightweight panels that maintain structural integrity when cut.

An adjustable wind guard shields sheet stock material from wind while a guide element maintains alignment during machine rotation to prevent jamming.

A nozzle probe locates apertures while pulsating air opens check valves in flexible structures.

Independent electronic control of transport and pressing mechanisms eliminates mechanical coupling constraints, enabling higher throughput rates.

Crowned belts and resilient backing maintain film flatness during longitudinal sealing, eliminating wrinkles and burning to increase production speed.

A heating element with varied cross-sections creates localized high temperatures to seal film plies.

A dunnage conversion system uses a converging chute to crumple sheet stock material before pinch rollers expand it into volumetric void-fill product.

Pivoted bracket maintains constant paper web tension to prevent tearing at high conveying speeds and ensure reliable machine operation.

A compact tabletop inflation system uses a silent compressor and solenoid-driven duckbill clamp to deliver rapid airbag filling.

A dunnage accumulator uses flexible holding portions to vary the accumulation space and retain crumpled material.

An inflatable web features multiple panels in fluid communication through a common inflation zone for flexible post-inflation configuration.

Nested wrap plies around cores create an L-shaped edge protector that resolves structural integrity issues in laminated paperboard designs.

Square paper napkins feature pre-printed color patterns that form 3D images upon folding.

Preliminary edge contraction prevents fluid escape during inflation, reducing required pressure and operational noise for cost-effective manufacturing.
