Vent Arrangements TRIZ Cases

Integrated tray ribs create a pressure relief cavity that vents battery gas while simplifying box installation and reducing weight.

A segmented vent path narrows then expands gas flow to prevent choking and shock waves while protecting the venting disk in battery packs.

A metal filter in the battery vent path captures fine particles from discharged gas, lowering external ignition risk without complicating the duct.

An insulating boss with first and second through holes separates the electrode assembly from the vent while maintaining a pressure relief path.

A protecting component channels battery cell vent emissions to both ends and away from high-voltage parts, lowering secondary ignition risk.

A corrugated lid forms cell enclosures and vent channels to release runaway gas quickly while limiting spread and reverse airflow.

A heat-triggered extinguisher sheet and insulation spacers suppress ignition, cool cells, and limit fire spread in dense battery modules.

A semipermeable membrane and elevated passageway equalize cavity pressure during submersion while blocking water ingress.

Heat pipes and conductive cell frames cut battery pack weight while improving cooling and vent-safe cell orientation in eVTOL aircraft.

Directional venting holes and pressure-openable protrusions redirect runaway gas and flame to limit adjacent-cell ignition and external damage.

Two overlapping separation screens vent battery housing gas quickly while retaining particles and limiting pressure loss during cell defects.

A modular frame and cover-integrated cooling member let battery packs vary cell assembly count while improving coolant flow and heat dissipation.

Distributed heat absorbers between and beside cells vaporize liquid to cool overheated batteries and limit thermal propagation.

A hollow metal housing stores coolant that releases through a meltable stopper to absorb heat, limit propagation, and reduce battery fire risk.

Partitioned air passages and exhaust vents channel flame, smoke, and gas from each battery cell to limit spread and secondary pack damage.

A thicker first shell wall strengthens pressure relief mechanism support, improving battery cell venting safety and service life.

Venting holes, barrier members, and fire-resistant sheets discharge failure gases and limit heat and flame transfer between stacked battery cells.

A pressure-responsive venting panel widens the gas path during cell failure to discharge gas quickly while limiting oxygen ingress and chain ignition.

Separate can sections joined by laser welding overcome deep-drawing length and wall-thickness limits in p-type prismatic cells.

Segmented venting channels and a collection area separate particles from vent gas, reducing arc and fire risk in battery modules.

Dual venting pathways and balance valves discharge thermal runaway emissions quickly to limit pressure buildup, thermal diffusion, and damage.

Gas-tight venting channels direct battery vent gas toward a collection area that traps particles, reducing arc and short-circuit risk.

A spring-backed contact element sets low, precise emergency degassing pressure while protecting the membrane from normal pressure fluctuations.

An integrated I-shaped housing support stiffens pouch battery modules, prevents cell deformation, simplifies assembly, and improves explosion resistance.

An impermeable rupture membrane enables valid accumulator EOL pressure testing while preserving normal gas equalization and vent integrity.

An upside-down cell layout places the end cap, terminals, and pressure relief at the case bottom to improve collision stress distribution and rigidity.

A membrane vent with monitored emergency opening balances battery housing pressure while blocking moisture, dirt, and liquid ingress.

Segmented support plates and suspension beams let inverted battery cells raise energy density without sacrificing rigidity or pressure relief safety.

An impermeable rupture membrane enables sealed accumulator EOL pressure testing while the breathing membrane preserves long-term pressure equalization.

A sealed battery containment uses cooling fluid and exhaust venting to suppress thermal runaway and discharge toxic gases safely.

Frame-mounted battery cell assemblies use insertion holes and a cover cooling member to vary pack capacity while improving coolant flow and heat removal.

A dual sensing probe monitors both cell terminals and vent gas, cutting thermal runaway detection delay without adding sensors to every battery cell.
