Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single communication technology is used for digital access, then the system is simple to implement, but communication reliability deteriorates when that technology fails
Solution Approach 1:
The patent combines multiple communication technologies (cellular, Wi-Fi, Bluetooth, UWB) into a unified digital access system that can switch between them. The state assessment optimizer merges these different communication methods into a single managed system, allowing the vehicle to leverage multiple technologies while maintaining a unified interface for digital access functions.
Solution Approach 2:
The system dynamically selects and switches between different communication technologies based on real-time state assessment. The state assessment optimizer continuously monitors communication quality and dynamically adjusts which technology is active, transforming a static single-technology system into a dynamic multi-technology system that adapts to changing conditions.
2Reliability
If multiple communication technologies are implemented, then communication reliability improves through alternatives, but system complexity increases
Solution Approach 1:
The state assessment optimizer implements continuous feedback monitoring of communication events, latency, and packet error rates. This feedback mechanism automatically assesses the state of each communication technology and triggers switching decisions when failures or suboptimal performance are detected, managing system complexity through intelligent automation rather than manual configuration.
Solution Approach 2:
The digital access system performs self-diagnosis and self-correction through the state assessment optimizer, which automatically detects communication failures, evaluates alternative technologies, and executes switching decisions without user intervention. This self-service capability manages the complexity of multiple communication technologies by automating the selection and switching process.
3Reliability
If communication technology is selected without optimization, then system operation is simple, but latency and packet errors increase
Solution Approach 1:
The state assessment optimizer performs preliminary assessment of communication technologies before actual digital access operations. By pre-evaluating available technologies and their current states, the system prepares optimal communication paths in advance, reducing latency during actual access operations. This preliminary action allows the system to quickly switch to optimal technologies without extensive real-time decision-making delays.

AI summary
Examples described herein provide a method for optimization and management of a digital access system for a vehicle. The method includes monitoring a digital access function of the digital access system of the vehicle to detect an event. The method further includes determining, using a state assessment optimizer, whether the event indicates a failure of the digital access function of the digital access system. The method further includes, responsive to determining that the event indicates a failure of the digital access function of the digital access system, assessing, using the state assessment optimizer, sub-events of the event that failed, evaluating, using the state assessment optimizer and based at least in part on the sub-events of the event that failed, other communication technologies to identify an alternative communication technology and re-executing, using the alternative communication technology, the digital access function that failed.
