TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a high-voltage cable with large diameter is used to meet high-power motor requirements, then the current transmission capability is improved, but the assembly process requires manual mounting which increases labor cost and time cost
Why choose this principle:
The high-voltage cable is segmented into multiple parallel sub-cables, each with smaller diameter. This allows the cable bundle to be automatically assembled while maintaining the required current transmission capability through parallel conduction paths
Principle concept:
If a high-voltage cable with large diameter is used to meet high-power motor requirements, then the current transmission capability is improved, but the assembly process requires manual mounting which increases labor cost and time cost
Why choose this principle:
The cable assembly uses composite structure combining multiple conductive materials or layered configurations, enabling both high current capacity and reduced individual cable diameter for automated handling

Abstract
A connector assembly having a liquid cooling function and a vehicle. The connector assembly includes at least one electrical connection framework and a connector that includes a connection terminal. Two ends of the electrical connection framework are electrically connected to the connection terminal respectively, and the electrical connection framework is provided with at least one hollow inner cavity, through which a cooling liquid flows. The connector assembly adopts the liquid cooling technology to reduce the heat generation amount of the electrical connection framework, so that the electrical connection framework can conduct a large current with a small wire diameter to ensure the normal use of the high-voltage device.
