Cell Lids/Covers TRIZ Cases

A pivoting frame-tube cover with sliding lock elements enables easy battery removal while keeping the bicycle frame seamless and secure.

A current collector with a resistance-increasing weak region cuts overcurrent quickly, limiting heat rise in high-output battery packs.

Edge and corner adhesive buffers capture overflow in stacked cell modules, improving bond uniformity and structural rigidity.

Separated inner and outer cover layers block flame spread between cells while guiding vented gas through divided channels.

Inclined guide portions align multiple electrode leads with bus bar slits, easing battery module assembly and improving heat dissipation.

A preset reference point offsets crystallization at the liquid injection hole, enabling precise sealing nail placement and safer battery sealing.

A partition wall and aligned opening steer discharged cell gas to a pressure relief valve, protecting electronics and maintaining case pressure.

A modular terminal with top and bottom joint portions fits one cap plate hole design, cutting bonding complexity, cost, and production time.

A sliding cover, button, and elastic sheet make camera battery access easier while keeping the cover attached, waterproof, and dustproof.

Protrusions and insertion holes align and secure the bus bar frame, preventing bending and improving battery module assembly stability.

Frame cut-outs with double injection-molded resin prevent bat-ear interference, improve insulation, and reduce resin thickness and manual tape work.

Plastic-to-plastic welding between terminal and cap insulators avoids metal weld defects, improves bonding strength, and lowers battery terminal cost.

Conductive frames on both pouch-cell surfaces create stackable terminal connections, cutting pack parts, assembly steps, and sealing risk.

A liquid absorbing member captures free electrolyte between the electrode assembly and insulator to reduce corrosion, leakage, and battery failure.

Inter-plastic welding between terminal and cap insulators removes uncertain metal adhesion, reducing battery terminal welding failures and cost.

A stepped bottom plate and recessed end plate improve battery module case welding, boosting bonding force, yield, and structural stability.

Pressed duct sections and seal members form an airtight vent path along battery cells, limiting gas leakage while preserving rigidity.

Honeycomb through-hole side plates restrain battery module swelling during charge and discharge, helping prevent deformation and leakage.

A one-piece stamped tub removes bottom-to-wall sealing joints, cutting enclosure weight, assembly complexity, and leak or fracture risk.

A jig-released lock pin secures the battery cover against child removal while capillary paths guide liquid away from the battery compartment.

A threaded hole in the battery cover secures the fuse box on top of the battery, saving space, lowering cost, and reducing stress on the pole.

A buffer portion with a defined separation start point lets a vehicle battery pack resist top loads while still allowing easier maintenance disassembly.

Segmented cell covers and a bottom vent route thermal gases downward while reinforcing pouch cells and limiting heat propagation.

A vent plenum, escape duct, and skip-module wiring improve gas release, lifting strength, and energy density in stacked battery storage modules.

Compressed elastic seals and shoulder screws keep the battery pack waterproof while venting failure gas quickly without outside air ingress.

A tilted fuel cell stack case uses opposing surface slopes and ribs to drain water away from the lid seal and maintain airtightness.

A pressed case edge and laser-welded cover improve battery sealability after liquid injection while minimizing dead space and raising capacity.

A deformable weld plate keeps battery tab stacks planar during welding, avoiding pre-welding and reducing bending that weakens the connection.

A depressible detent cover secures a coin-cell battery yet flexes for easy release, avoiding jamming during installation and removal.

An integrated elastic terminal cover insulates battery module terminals, prevents short circuits, reduces part loss, and simplifies assembly.

An insulated fixing structure bonds battery module components to suppress cell shaking, wiring damage, friction, and short-circuit risk.

Staggered upper and lower cover notches maintain battery cell vent pressure while reducing notch formation, mold damage, and production loss.

A protrusion-guided terminal post with plastic lug and sealing rings blocks electrolyte leakage, corrosion, and insulation loss.

Exhaust holes between adhesive injection tracks release foaming bubbles in a battery pack cover, preventing vacuoles and improving bond strength.

A pressed vent duct bottom and seal members keep battery-cell discharge gas contained and flowing reliably under vehicle vibration.

A double shear screw-boss layout secures the battery cell carrier against disconnection while maintaining reliable power transmission.

Overlapping welded side plates and a band member raise battery module rigidity, simplify manufacturing, and improve cell swelling control.
