Vent Arrangements TRIZ Cases

Fixing an insulating packing strap to end plates avoids hot-melt burrs, simplifying battery assembly while protecting separators from shorts.

Directional venting and manifold ignition treat Li-Ion thermal runaway fumes with simpler fire and pollution control.

Reverse-tapered venting ports redirect heat, gas, and flames out of dense battery modules to suppress propagation and continuous ignition.

A built-in grating breaks up particles ejected during battery cell failure, relieving pressure while reducing short-circuit risk in adjacent cells.

A layered heat sink creates separate heat-dissipation and gas-discharge paths between stacked cylindrical cells to help prevent chain ignition.

A sealed phase-change insulator cools battery cells through liquid-gas cycling, improving heat dissipation while limiting thermal runaway risk.

A protruding tube links each battery cell to a degassing channel, redirecting runaway gases away from connectors without melt-prone seals.

A sensor module tracks battery gas leakage in real time and adjusts charging to prevent heat- or overcharge-driven safety incidents.

A three-layer resin vent member releases thermal gases in a controlled direction while preserving battery sealing and delaying early venting.

Gas flow channels in porous elastic spacers help battery packs maintain stable restriction load and cell compression during discharge.

Separated cell assemblies, cooling flow paths, and a venting cover improve heat dissipation and gas discharge in large battery modules.

Gas discharge holes and tape moving holes disperse high-temperature battery gas pressure to prevent insulating plate rupture.

Localized laser or embossing-weakened membrane zones enable fast low-pressure gas release while keeping thicker films easy to seal and handle.

A deformable valve sleeve in the top cover opens a gas exhaust path under slow pressure rise, then reseals to protect battery integrity.

A thin sealing member matched to electrode assembly thickness removes shark-fin protrusions, improving pouch battery packing density and cooling.

A longitudinal beam and load-bearing cells enable tighter battery spacing with less insulation, improving heat transfer and pack rigidity.

Cabin humidity is regulated by feeding fuel cell cathode off-gas based on sensor readings, balancing heating use with passenger comfort.

An integrated rupture disc in the cell tab enables targeted pouch-cell degassing through an internal channel, reducing pressure buildup and thermal runaway risk.

A cross frame, upper cover, and shielding member vent thermal runaway gas outside while blocking flame spread between battery modules.

Integrated venting passages, flange shielding, and vent holes discharge runaway gas outward while blocking flame spread between battery modules.

An adjustable spring-biased valve controls battery pack pressure and gas ejection velocity to prevent case damage and ignition risk.

A movable valve core bypasses the breathable membrane under high gas pressure, balancing normal venting with rapid battery pack pressure release.

Stepped cell end portions create shared cooling and gas discharge paths, improving battery pack venting without extra ducts or lost energy density.
