Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical lever is used to control connection/disconnection, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent replaces the mechanical lever system with an electromagnetic control system. A magnetic component interacts with a magnetic field generated by an electromagnetic actuator to control the connection state. This substitution eliminates the direct mechanical linkage that allowed unauthorized card changes, while maintaining ease of operation through electromagnetic actuation controlled by authentication logic.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the control system and the mechanical connection component. The electromagnetic actuator generates a magnetic field that actuates the magnetic component, which in turn controls the connection state. This intermediary layer allows for controlled authentication-based operation while preventing direct mechanical manipulation.
2Device complexity
If a mechanical connection structure is used, then device complexity is reduced, but security deteriorates
Solution Approach 1:
The patent replaces the simple mechanical lever structure with an electromagnetic control system consisting of an electromagnetic actuator, magnetic component, and control circuitry. While this increases device complexity, it enables authentication-based security control that prevents unauthorized access, thereby improving reliability.
Solution Approach 2:
The patent changes the control parameter from direct mechanical movement to electromagnetic field interaction. The electromagnetic actuator controls the magnetic field strength, which in turn controls the actuation of the magnetic component. This parameter change enables fine-grained control over the connection state based on authentication results.
