TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the motor and motor controller are integrated to reduce footprint, then space utilization is improved, but the connection structures and cooling systems become more complex
Why choose this principle:
The patent integrates the motor controller directly into the motor housing, merging two previously separate components into a single unified assembly. This reduces the overall footprint while the housing itself serves as the connection structure, simplifying the integration complexity.
Principle concept:
If the motor and motor controller are integrated to reduce footprint, then space utilization is improved, but the connection structures and cooling systems become more complex
Why choose this principle:
The housing serves multiple functions: it contains the motor components, houses the controller, provides cooling channels, and acts as a structural connection element. This multi-functionality reduces the need for separate connection structures and cooling systems.

Abstract
The present disclosure relates to the field of new energy, and provides a three-phase terminal block, a drive assembly, and a vehicle. The three-phase terminal block includes a cylindrical terminal block body and three single-phase terminals each arranged along an axial direction of the terminal block body, wherein the single-phase terminals each are provided with a first terminal portion and a second terminal portion on two ends. The three single-phase terminals are arranged at an outer circumference of the terminal block body to connect terminals of a stator correspondingly, thereby optimizing the wiring layout. In addition, the space formed by the three single-phase terminals can accommodate components, thereby improving the compactness of the structure layout.
