Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle functionality is enabled for normal operation, then ease of operation is improved, but security control is weakened
Solution Approach 1:
The system dynamically switches between normal mode and service mode based on operational context. In normal mode, full functionality is accessible for ease of operation. In service mode, accessibility is restricted to protect security controls. This dynamic switching resolves the contradiction by adapting the system state to current operational needs.
Solution Approach 2:
Different security levels are applied to different functional areas based on the current mode. In normal mode, user-facing functions have high accessibility. In service mode, only authorized service functions are accessible while personal information remains protected. This localized quality approach allows simultaneous optimization of ease of operation and security control in different system areas.
2Ease of operation
If personal information is made accessible for user convenience, then ease of operation is improved, but privacy security is worsened
Solution Approach 1:
The accessibility of personal information dynamically changes based on the vehicle mode. In normal mode, personal information is accessible to users for convenient operation. In service mode, personal information becomes inaccessible to prevent privacy breaches. This temporal dynamic control resolves the contradiction between accessibility and privacy protection.
3Reliability
If security controls are strengthened to protect personal information, then reliability is improved, but ease of operation is worsened
Solution Approach 1:
The system segments functionality into two distinct modes: normal mode for user operations and service mode for authorized access. This segmentation allows strong security controls to be applied specifically to personal information access without affecting general vehicle operation in normal mode, thus maintaining ease of operation while ensuring security when needed.
4Reliability
If vehicle functionality is restricted for security purposes, then reliability is improved, but adaptability is worsened
Solution Approach 1:
The system adapts its functionality based on the current mode dynamically. In normal mode, full adaptability is available for user convenience. In service mode, restricted functionality provides enhanced security while still allowing necessary service operations. This temporal adaptability resolves the contradiction by providing different functionality levels at different times based on operational context.

AI summary
An example operation includes setting a mode of a vehicle based on an operation of the vehicle, a characteristic of the vehicle, a time, and/or a location of the vehicle. The mode is any of a service mode wherein personal information of a user of the vehicle is inaccessible; a development mode wherein a functionality of the vehicle is able to be modified, tested and/or validated, and wherein a security control of the vehicle is limited; and a normal mode wherein the functionality of the vehicle is enabled and the personal information of the user of the vehicle is accessible and modifiable.
