Electric Connector Introduction TRIZ Cases

A recessed battery bottom plastic with flow guide holes improves injection molding, cuts thickness, and buffers electrolyte pressure to protect cells.

A clamped metal-layer pole with press riveting and laser welding boosts bonding strength and reduces composite battery terminal separation.

A wrapped and embedded metal layer increases composite battery pole bonding area, reducing detachment risk and improving current durability.

By riveting the post from the inner terminal side, this case removes weld protrusions, improves busbar fit, and stabilizes battery current.

Differential tab-sheet compaction places the weld edge in a denser zone to cut cracking, raise conductive yield, and strengthen battery terminals.

Insulating the lead-out member surface while leaving a tab opening helps prevent short circuits from fallen active material inside battery cells.

Differential tab-sheet compaction places the weld edge in a denser area to reduce cracks, lower pulling stress, and strengthen terminal-post joints.

A second bending portion locally binds battery tab layers, resisting separation and reducing short-circuit risk in bent cells.

A built-in rotatable connector keeps battery cells disconnected until user activation, reducing self-discharge and avoiding loose connector parts.

Alternating cell orientation and intercell cooling members block flames and heat spread, helping battery modules prevent thermal runaway.
