Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security systems are hardwired to individual vehicle devices, then reliable control is achieved, but wiring complexity and device compatibility issues increase
Solution Approach 1:
The patent introduces a controller as an intermediary device that connects to the data communications bus and communicates with vehicle devices wirelessly. This controller mediates between the remote control device and the vehicle's security systems, eliminating the need for direct hardwired connections while maintaining reliable control through standardized bus communication protocols
2Reliability
If hardwired connections are used for security systems, then stable communication is achieved, but adaptability to different vehicle models and manufacturers is reduced
Solution Approach 1:
The controller is designed with multi-functionality to interface with various vehicle data communications buses (CAN, LIN, FlexRay, MOST) and support multiple communication protocols. This universal design enables the same controller to adapt to different vehicle models and manufacturers while maintaining stable communication through protocol translation and standardized bus interfaces
3Device complexity
If wireless communication is implemented for remote control, then wiring complexity is reduced, but communication reliability in harsh vehicle environments may be compromised
Solution Approach 1:
The controller serves as a protected intermediary that receives wireless commands and translates them into reliable bus communications. It incorporates error handling, signal validation, and protocol conversion to ensure that wireless communications are reliably transmitted through the vehicle's existing robust bus infrastructure, maintaining communication reliability while eliminating complex wiring
4Device complexity
If multiplexing schemes are adopted to reduce wiring, then weight and routing problems are reduced, but implementation complexity and error-free communication requirements increase
Solution Approach 1:
The controller automatically performs configuration, protocol detection, and communication parameter negotiation when connected to the vehicle's data communications bus. It self-configures to work with the specific bus type and protocol being used, eliminating the need for complex manual configuration and reducing implementation complexity while maintaining error-free communication through automated error handling and validation
