Engineering Contradiction Analysis
1Use of energy by moving object
If an electronic starter is used to reduce power consumption, then power consumption is reduced, but the connection between the compressor starter and the compressor becomes cumbersome
Solution Approach 1:
The connector is divided into two separate parts: a first connector integrated with the compressor starter and a second connector integrated with the compressor. This segmentation allows each connector to be optimized for its specific function and enables easy connection and disconnection by simply bringing the two parts together, eliminating the cumbersome wiring associated with electronic starters
Solution Approach 2:
The connector assembly acts as an intermediary component that bridges the compressor starter and the compressor. This intermediary structure provides a standardized interface with multiple connection points, simplifying the connection process while maintaining reliable electrical contacts for the electronic starter's low-power operation
2Ease of operation
If a simple plug structure is used to facilitate connection, then connection convenience is improved, but connection reliability may be compromised
Solution Approach 1:
The connector integrates multiple functions into a single unified structure: mechanical connection, electrical connection, and positioning are all combined in one component. This merging ensures that when the connector is assembled, all connection functions are simultaneously activated, providing both ease of operation and reliable connection without requiring separate mechanisms for each function
Solution Approach 2:
The connector is pre-configured with built-in electrical contacts and conductive structures during manufacturing. This preliminary preparation ensures that when the connector is installed, reliable electrical connections are immediately established without requiring additional assembly steps or separate wiring operations, thus maintaining both simplicity and reliability

AI summary
A plug assembly includes a plug body defining at least one mounting through hole and at least one a connecting post passing through the mounting through hole. Each connecting post has a first end located in the mounting through hole to be configured for plug-in connection with a terminal of a compressor, and a second end extending beyond the mounting through hole to be configured for connection with a control board. A compressor starter can include the plug assembly. A compressor assembly can include the compressor starter.
