Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a connector is designed to be easily coupled and separated, then ease of operation is improved, but connection strength may be insufficient
Solution Approach 1:
The patent replaces the traditional mechanical coupling system with a magnetic field-based system. Magnets embedded in the connector housing generate magnetic attraction forces that automatically draw the battery pack and external device together during coupling, eliminating the need for strong manual pushing forces while maintaining reliable connection strength.
Solution Approach 2:
The patent utilizes the adjustable parameter of magnetic field strength through the use of magnets with specific magnetic properties. By carefully selecting magnets with appropriate magnetic moments, the system achieves optimal balance between easy coupling (sufficient magnetic attraction) and secure connection (maintained magnetic holding force), resolving the contradiction between ease of operation and connection strength.
2Strength
If strong force is applied to ensure secure connection, then connection strength is improved, but the connector is easily damaged
Solution Approach 1:
The patent substitutes mechanical fastening forces with magnetic field forces. The magnetic attraction provides sufficient connection strength to secure the battery pack while avoiding the concentrated mechanical stresses that would damage the connector housing, terminals, or surrounding components.
Solution Approach 2:
The magnetic field acts as a cushioning mechanism that distributes the connection force uniformly across the magnetic components rather than concentrating it at specific mechanical contact points. This prevents localized stress concentrations that could lead to connector damage while maintaining overall connection integrity.
3Ease of operation
If magnets are used to facilitate easy coupling, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the magnetic coupling function directly into the connector housing structure. The magnets are embedded within the housing, combining the structural support function of the housing with the magnetic attraction function, thereby adding minimal complexity while achieving easy coupling operation.

Function Achieved in This Case
Minimizes damage to connectors during coupling and separation operations by utilizing magnetic forces for easy attachment and detachment.
Implementation Method 1
the connector structure (e.g., the male connector) coupled to the female connector includes a magnet. In the coupling mode, the connector structure may be more easily coupled to the female connector by using the magnetic force of the internal magnet.
Implementation Method 2
In the separating mode, the connector structure uses the magnet of the removing tool to offset the magnetic force.

AI summary
The present invention provides a connector structure in which a male connector and a female connector are easily coupled to each other. The connector structure of the present invention includes a coupling part, a housing, and a first removing tool. The coupling part is coupled to the female connector in a coupling mode and separated from the female connector in a separating mode. The housing includes a first magnet on a first surface among surfaces surrounding the coupling part and is configured to attract the female connector by using magnetic force of the first magnet. The first removing tool is configured to rotate a second magnet in the separating mode so as to weaken the magnetic force.
