Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw or elastic terminals are used for electrical connections, then reliable electrical contact is achieved, but connection time increases significantly
Solution Approach 1:
The patent replaces the manual mechanical screwing operation with a magnetic field-based attachment system. The permanent magnet in the connector automatically attracts to the terminal, eliminating the need for manual screwing while maintaining secure mechanical and electrical connection. This substitution of mechanical fastening with magnetic attachment directly resolves the contradiction between reliable contact and connection time.
Solution Approach 2:
The connector performs self-alignment and self-attachment through magnetic attraction between the permanent magnet and the terminal. The operator simply needs to bring the connector near the terminal, and the magnetic force automatically guides and secures the connection without requiring manual positioning or fastening operations, thus dramatically reducing connection time while ensuring reliable contact.
2Reliability
If individual conductor connection to each terminal is performed manually, then proper electrical connection is established, but productivity decreases
Solution Approach 1:
The invention divides the connection task into independent modular connectors, each handling one terminal individually. Each connector is a self-contained unit with its own permanent magnet and conductive elements, allowing multiple connectors to work simultaneously on different terminals without interfering with each other. This segmentation enables parallel connection operations, significantly improving productivity while maintaining connection quality.
Solution Approach 2:
The connectors are pre-assembled with permanent magnets and conductive elements before use. This preliminary preparation allows the connectors to be immediately deployed for testing without requiring assembly during the testing process, enabling rapid sequential or parallel connection to multiple terminals and thus improving overall testing productivity.
3Speed
If permanent magnets are used for quick connection, then connection speed increases, but electrical conductivity path must be ensured
Solution Approach 1:
The patent combines multiple functions into a single integrated connector structure: the permanent magnet provides both the attachment force and serves as part of the electrical conduction path. The conductive elements are merged with the magnetic assembly, creating a unified component that simultaneously achieves quick magnetic attachment and reliable electrical connection, thereby increasing connection speed without proportionally increasing device complexity.
Solution Approach 2:
The conductive elements act as intermediaries between the permanent magnet and the terminal. These elements ensure proper electrical contact while allowing the permanent magnet to remain positioned optimally for magnetic attraction. This intermediary structure enables the connector to achieve both quick magnetic attachment and reliable electrical conduction with minimal added complexity.
