Domestic Seals TRIZ Cases

A resin blend of cycloolefin polymer, copolymer, and polyethylene improves heat sealing performance.

Dual-weight polysiloxanes in a TPE matrix reduce friction and wear on window weatherseals during wet cycling.

Segmented comonomer distribution in propylene copolymers lowers seal initiation temperature while maintaining low hexane solubles content.

Acrylamide copolymer seals geotextile barriers against high conductivity salt water by expanding volume to fill fissures.

A multilayer sealant structure uses a cohesive failure layer to facilitate separation.

A stamping method forms S-shaped bent edges on heat-isolating metal components using specialized molds.

A vacuum mold tool draws sealant into sub-volumes via pressure differentials.

A pull-tab sealing member uses a foamed polymer layer to provide effective heat sealing integrity for container closures.

A monomaterial polyethylene laminate structure combines high-density and linear low-density layers to achieve suitable print registration.

A sheet-like sealing material with specific colorimetric properties and high light transmittance at 420 nm protects electronic components.

A bitumen sealing membrane uses exposed longitudinal edges to connect adjacent conductive layers automatically during installation.

Coating liquid polyol and crosslinker eliminates extrusion defects like gel and fisheyes in swelling tape.

An absorbing printed layer covering 50-95% of the surface area prevents delamination and forgery in secure documents.

Grooved epoxy resin sheets adapt to various pipe sizes, eliminating heavy metal collars and complex inventory requirements.

NIR laser transmission welding joins foam layers to functional bands without compromising porosity.

Silane coupling agent forms a durable film on rubber-metal laminated gaskets, eliminating chromium and fluorine waste.

A gas-barrier laminate uses a specific coating layer to enhance interlaminar bonding between the base plastic film and inorganic thin film.
