Association With Control/Drive Circuits TRIZ Cases

A connecting device uses a linear bus bar with a bowed interface to crimp drive current lines and clamp switchgear units.

Segmenting the slot into introduction, scrape, and fix parts widens conductor pieces to prevent separation and falling during connection.

Sealing structures protect the display panel from environmental deterioration, ensuring reliable operation of the electric work machine.

A motor drive device uses a duct to channel outside air for cooling heat sinks.

Separating smoothing capacitor and coil from the control board via an electrical connection member reduces temperature rise in the motor drive module.

Radial windows in the connector housing allow welding of electrical contacts, eliminating printed circuit boards to withstand high temperatures and vibrations.

Polygonal insulator flat portions engage case detents to prevent idling between the stator and resin motor housing.

Integrated electronics merge sensing, control, and power distribution to resolve automation complexity trade-offs while enhancing system reliability.

A card edge connector joins motor and controller printed circuit boards through direct contact.

Long bolts absorb collision impacts to prevent casing breakage without adding separate protective components or increasing weight.

Replacing mechanical brushes with electronic commutation via a contactless position sensor eliminates wear and arcing in aircraft actuators.

Coupling valves connect dual coolant pumps to independent circuits, maintaining full cooling capacity when one pump fails.

A connector system couples power lines to a hermetically sealed inverter housing cover, integrating electrical and mechanical functions.

A device cooling passage with a high inlet and low outlet directs coolant downward through a power converter housing.

A detachable guide pin structure aligns electric motor and inverter units during assembly without permanent weight addition.
