Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automated pairing process is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring authentication certificates in both the vehicle and smartphone, and pre-establishing the notification signal broadcast mechanism. When pairing is needed, the system only needs to execute the pre-planned sequence of actions (detect notification signal → establish BLE connection → verify identity → complete pairing) without requiring complex real-time decision-making or user intervention.
Solution Approach 2:
The pairing system performs self-service through automated identity verification using pre-stored certificates, automatic connection establishment based on detected notification signals, and self-completion of the pairing process without human intervention. The vehicle controller and smartphone work autonomously to complete the entire pairing sequence.
2Reliability
If multiple verification steps are implemented, then reliability is improved, but time consumption increases
Solution Approach 1:
Authentication certificates are pre-installed in both the vehicle controller and smartphone before pairing occurs. This preliminary configuration eliminates the need for real-time certificate distribution or complex verification algorithms during the actual pairing process, allowing rapid yet secure verification.
Solution Approach 2:
The system replaces manual verification processes (mechanical/user-based) with automated electronic verification using Bluetooth Low Energy communication and cryptographic certificate validation. This substitution enables multiple verification steps to execute rapidly without user interaction, maintaining security while minimizing time loss.
