Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital vehicle key solutions rely on specific public protocols with native system components, then communication reliability is improved, but device compatibility deteriorates and configuration costs increase
Solution Approach 1:
The patent introduces a communication device as an intermediary layer between the terminal device and the digital vehicle key system. This communication device translates and adapts communications between different protocols, allowing terminal devices without native protocol support to interact with the digital vehicle key system. The intermediary handles protocol conversion, enabling both reliable communication and broad compatibility simultaneously.
Solution Approach 2:
The communication device is designed with multi-functional capabilities to support multiple communication protocols and adapt to different terminal devices. It can detect the capabilities of connected devices and dynamically adjust its communication method, making the system universally applicable across different device types while maintaining reliable digital vehicle key functionality.
2Reliability
If digital vehicle key solutions are customized for specific manufacturers, then communication reliability is improved, but device complexity and configuration costs increase
Solution Approach 1:
The communication device serves as a universal intermediary that handles manufacturer-specific protocol variations. Instead of customizing each terminal device for different manufacturers, the communication device adapts to different manufacturers' protocols, simplifying the terminal device design while maintaining reliable communication with various digital vehicle key systems.
Solution Approach 2:
The communication device includes automatic detection and adaptation capabilities that allow it to self-configure when connecting to different terminal devices or digital vehicle key systems. This self-service functionality reduces configuration complexity by automatically identifying the connected device type and adjusting communication parameters without manual intervention.
3Reliability
If native system components for public protocols are integrated into terminal devices, then digital vehicle key functionality is ensured, but resource consumption and development costs increase
Solution Approach 1:
The communication device acts as an on-demand intermediary that is only activated when digital vehicle key functionality is needed. Instead of permanently integrating protocol components into the terminal device, the communication device provides protocol translation services only when required, reducing overall resource consumption while ensuring functionality when needed.
Solution Approach 2:
The system uses a lightweight communication device that can be temporarily activated or deactivated based on need, rather than permanently burdening the terminal device with heavy protocol components. This approach reduces the terminal device's resource requirements while maintaining the ability to perform digital vehicle key operations when necessary.

AI summary
A terminal device (10) includes a communication device (100), configured to detect whether a native system of the terminal device (10) includes components for adapting a public protocol of a digital vehicle key, and communicating with a target communication party based on the public protocol in case of an absence of at least one of the components in the native system, in which the target communication party is a participant of the public protocol.
