Cell Lids/Covers TRIZ Cases

Segmented sub-modules and nested cell arrangements resolve the contradiction between high power output and increased volume in compact battery modules.

Blocking members partition battery cells and vent high-temperature gas externally to prevent thermal runaway propagation.

Moving the adapter compartment from the cover to the device body reduces cover weight, easing operation and preventing component damage.

Perpendicular airflow contacting the case bottom face reduces thermal resistance, resolving low efficiency from parallel lid cooling.

Integrated elastomeric frame components mitigate axial shock damage and vibration transmission, reducing assembly complexity while enhancing device durability.

Relocate auxiliary power unit and battery box to vertical space between frame rails, eliminating driveline interference and reducing noise.

An outer case rib and holder projection use asymmetric positioning to prevent wrong assembly errors while maintaining common mold costs.

Planar cell cover design with interlocking recesses avoids three-dimensional deformation to reduce installation space.

Centered welded unit reduces cap plate deformation by half, ensuring stable coupling and lower production costs.

Bus bar shielding portions prevent case cover removal without disconnecting electrical connections, simplifying battery pack designs.

Supporting projections on connecting flanges create tension legs that concentrate force, eliminating extra sealing elements and reducing assembly complexity.

Superimposed positioning of service plugs prevents premature cover removal, resolving the safety-complexity trade-off in high voltage battery packs.

A battery module housing uses cooling ribs and compensation mechanisms for spatial fixation.

Segmented cover extensions engage battery holder projections to define a gas flow path, preventing leakage caused by thermal or vibrational deformation.

Relocating protection components to the external top cover reduces internal space occupation, enhancing energy density while maintaining overcharging safety.
