Assembling Battery Machines TRIZ Cases

Lower and upper air blowing units bend separator sheet ends to prevent hyphen-shaped folds that cause low voltage defects in lithium ion polymer batteries.

Segmented position-limiting member with threaded rod and clearance-fit second portion prevents loosening during repeated battery welding presses.

A shaping channel bends adhesive tape ends to match concave battery tab geometry, resolving sticking reliability issues.

A pouch battery production method applies tensile force to laminate film edges during sealing in a reduced pressure chamber.

Composite metal and polyacetal plates fold via a locking mechanism to reduce weight while restricting cell thickness expansion during activation.

Single pouch encloses multiple jelly rolls to increase capacity without expanding device width.

Synchronized drum rotation adheres and welds separators to moving electrode plates, resolving production speed bottlenecks.

A pattern member with pressing protrusions creates nonbonding spaces at the electrode-separator interface to enable electrolyte permeation.

A semi-elliptical pressing jig applies uniform pressure to discharge air bubbles from battery cells.

A segmented laser welding sequence reduces thermal stress and prevents battery cell damage during bus bar attachment.

Inclined support block guides internal gas through a dedicated passage during secondary battery manufacturing.

Adhesive seals battery cells to a middle housing divider, preventing coolant crossflow between chambers that degrades temperature regulation.

Cammed lifters reorient planar cells and fins vertically, bypassing high-precision pick-and-place tooling to boost throughput.
