Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional key fobs or keyless entry systems are used, then vehicle access is provided, but security level remains low and vulnerability to attacks increases
Solution Approach 1:
The authentication system is divided into multiple independent components: approach vector determination module, biometric authentication module, and chain of trust verification module. Each component performs a specific security function, collectively providing multi-factor authentication that significantly enhances security without requiring a single complex security mechanism
Solution Approach 2:
The patent introduces a mobile computing device as an intermediary between the user and the vehicle. This intermediary carries out biometric scanning, approach vector calculation, and authentication communication, thereby protecting the vehicle's core security systems while adding multiple verification layers through the intermediary device
2Ease of operation
If traditional keys or key fobs are used, then vehicle access is enabled, but convenience decreases due to size and misplacement risk
Solution Approach 1:
The patent replaces traditional mechanical key systems and radio frequency key fobs with an optical and computational approach. The mobile device uses camera-based biometric scanning and computational geometry for approach vector determination, substituting mechanical authentication with optical-field and information-processing methods that are both more convenient and more secure
Solution Approach 2:
Instead of requiring a physical key object, the system creates a digital copy of the user's biometric characteristics (facial features, iris patterns, etc.) stored in the mobile device. This digital biometric copy serves as the authentication credential, eliminating the need for physical keys while providing enhanced security through unique biological identifiers
3Adaptability or versatility
If single factor security systems are used, then access control is provided, but personalization and identification capabilities are lost
Solution Approach 1:
The authentication system dynamically adapts its behavior based on the approach vector and authentication context. The system can adjust authentication requirements, provide personalized welcome messages, and modify vehicle settings based on the identified user, transforming a static security system into a dynamic, personalized experience
Solution Approach 2:
The mobile computing device serves multiple functions: it acts as a biometric scanner, a computational unit for approach vector determination, a communication interface with the vehicle, and a personalization engine. This multi-functional approach consolidates multiple capabilities into a single device, reducing overall system complexity while enhancing personalization
Data Source
AI summary
A system provides a personalized and secure user experience to access a secured asset, such as a vehicle. A first communication is transmitted, and a second communication is received in response to the first communication. An approach vector is determined based on the first communication and the second communication. The approach vector is compared with a known approach vector, a request for authentication is transmitted based on the comparison. A response to the request for authentication is received, and access to an asset is granted based on the approach vector and the response to the request for authentication.
