Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle connectivity is increased to enable mobile control and Internet access, then ease of operation and functionality are improved, but vulnerability to hacking and security breaches worsens
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the vehicle's electronic systems. This intermediary provides a controlled interface that enables mobile control functionality while filtering and managing access to vehicle systems, thereby reducing direct exposure to security threats.
Solution Approach 2:
The system performs preliminary authentication and authorization actions before granting control access. The mobile device must be authenticated and the user must be authorized before any vehicle control functions can be accessed, preventing unauthorized access attempts before they can cause harm.
2Adaptability or versatility
If more electronic systems and sensors are added to enable connected vehicle features, then adaptability and functionality are improved, but reliability and risk of malfunction worsen
Solution Approach 1:
The patent implements feedback mechanisms where the mobile device receives status information from vehicle systems and provides controlled commands back to the vehicle. This closed-loop communication allows for monitoring and verification of system states, enabling the detection and correction of potential malfunctions before they compromise reliability.
Solution Approach 2:
The control system is segmented into distinct modules: the vehicle's electronic systems, the communication interface, and the mobile device application. This segmentation isolates potential failures to specific modules, preventing cascading failures across the entire system and improving overall reliability.
3Ease of operation
If control access is extended to mobile devices for passenger convenience, then ease of operation is improved, but security exposure and hacking risk worsen
Solution Approach 1:
The patent implements dynamic control where access permissions and control capabilities are not static but change based on authentication status, user role, and vehicle state. The system can dynamically adjust what functions are accessible to the mobile device, enabling convenient passenger control for approved users while maintaining security by restricting access to sensitive functions.
Data Source
AI summary
When a mobile device is securely connected to a vehicle, at least a portion of a control interface of the vehicle can be extended to the mobile device, allowing a user of the mobile device to operate certain functions of the vehicle from the mobile device. For example, a passenger of a vehicle can control some aspects of the vehicle, while the driver controls driving aspects. Optionally, the passenger can take the role of a co-driver or co-pilot of the vehicle in some embodiments.
