Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inductive power supply systems are implemented in motorized vehicles, then electrical power can be transferred wirelessly without contact problems or sparking effects, but the systems become vulnerable to unauthorized use and illegal access by non-registered users
Solution Approach 1:
The system performs a handshaking procedure and authentication exchange between the inductive power transfer system and the electrical device before initiating power transfer. This preliminary action verifies that the device is registered and authorized, preventing unauthorized access while maintaining reliable power transfer for legitimate users.
Solution Approach 2:
A communications security system acts as an intermediary between the inductive power transfer system and electrical devices. This security layer mediates authentication and authorization, allowing the system to maintain open wireless power transfer capability while blocking unauthorized access through cryptographic verification.
2Adaptability or versatility
If inductive power transfer is enabled for multiple electrical devices, then convenience and versatility are improved, but security risks and data access vulnerabilities increase
Solution Approach 1:
The system applies different security levels and authentication mechanisms to different electrical devices based on their specific requirements and risk profiles. Each device undergoes individual authentication and receives appropriate access permissions, allowing versatile support for multiple device types while maintaining tailored security measures for each.
Solution Approach 2:
The communications security system serves as an intermediary that manages authentication and data access for multiple electrical devices. It verifies each device's credentials and enforces appropriate access controls, enabling the system to support diverse devices while preventing unauthorized data access through centralized security management.
3Object-affected harmful factors
If a secure communications channel is established using handshaking procedures and authentication protocols, then protection against unauthorized access is improved, but system complexity and initialization time increase
Solution Approach 1:
The communications security system implements universal authentication protocols and standardized handshaking procedures that work across different electrical devices and platforms. By using widely adopted security frameworks, the system achieves comprehensive protection against unauthorized access while avoiding the need for device-specific complex security implementations.
Solution Approach 2:
The authentication and security verification processes are automated through self-service handshaking procedures between the inductive power transfer system and electrical devices. The system independently verifies credentials and establishes secure connections without requiring manual intervention, reducing operational complexity while maintaining robust security protections.
4Object-affected harmful factors
If authentication and handshaking procedures are implemented before power transfer, then security against illegal users is improved, but power transfer speed and efficiency are reduced
Solution Approach 1:
The system performs authentication and handshaking procedures as preliminary actions before initiating power transfer. While this adds initialization time, it ensures that only authorized devices receive power, preventing illegal access and potential damage. The security verification is completed once during connection establishment, minimizing ongoing time loss.
Solution Approach 2:
The authentication process is automated through self-service handshaking where the electrical device and inductive power system independently verify credentials without manual intervention. This automation reduces the perceived time loss by eliminating waiting periods for user input, making the security process feel more efficient despite the necessary verification steps.
