Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital vehicle key functions are integrated into mobile terminal devices using NFC, Bluetooth and UWB technologies, then vehicle access and control capabilities are improved, but the number of operations required by users increases significantly
Solution Approach 1:
The system enables the vehicle to automatically detect mobile terminals with digital vehicle keys in proximity and autonomously determine user identity and intent based on detection data, eliminating the need for users to manually operate the vehicle key application. The vehicle performs self-service authentication and control operations without requiring user initiation or confirmation.
Solution Approach 2:
The system pre-establishes digital vehicle keys in mobile terminals before the user reaches the vehicle. The vehicle continuously monitors for nearby mobile terminals and prepares authentication in advance, so that when a user approaches, the vehicle is already ready to authenticate and execute control operations without requiring the user to perform any preliminary actions.
2Reliability
If multiple specific operations are required in the vehicle key application, then security and control precision are improved, but user experience deteriorates due to complex操作流程
Solution Approach 1:
The vehicle autonomously determines user identity, location, and intent based on detection data from mobile terminals, and automatically executes appropriate control operations. This eliminates the need for users to navigate through multiple application menus and confirmation screens, while the system maintains security through automated authentication and authorization checks.
Solution Approach 2:
The system continuously receives detection data from mobile terminals, analyzes user intent based on this feedback, and dynamically adjusts control operations. The vehicle monitors user actions and environmental conditions, using this feedback to automatically determine the most appropriate operation without requiring explicit user commands for each action.
3Measurement precision
If the vehicle continuously monitors mobile terminals and processes detection data, then user intent recognition is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the vehicle performs detection and data processing at periodic intervals or triggered by specific events such as when a mobile terminal enters a predetermined distance range. This reduces energy consumption while maintaining accurate user intent recognition by checking at meaningful moments rather than continuously.
Solution Approach 2:
The monitoring intensity and processing frequency are dynamically adjusted based on current conditions such as vehicle state, number of nearby mobile terminals, and environmental factors. The system increases monitoring precision when needed (e.g., when users are approaching or interacting with the vehicle) and reduces it during normal operation to conserve energy.
