Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If analog communication protocols are used for special equipment vehicle functions, then vehicle control capabilities are achieved, but production costs increase significantly
Solution Approach 1:
The patent implements a universal signal conversion device that can convert multiple different vehicle control signals (CAN, LIN, Ethernet protocols) into a unified protocol that special equipment controllers can process. This multi-functional conversion capability allows a single controller design to work across different vehicle models and protocols, achieving economies of scale that reduce production costs while maintaining full vehicle control capabilities.
2Adaptability or versatility
If diverse special equipment vehicle functions are integrated, then vehicle functionality increases, but system complexity increases
Solution Approach 1:
The patent introduces a signal conversion device as an intermediary component between the vehicle's diverse communication networks (CAN, LIN, Ethernet) and the special equipment controllers. This mediator translates and standardizes signals from multiple protocols into a unified format, allowing complex diverse functionalities to be integrated without increasing overall system complexity, as the conversion device handles protocol variations centrally.
3Adaptability or versatility
If protocol conversion is implemented, then compatibility with special equipment controllers is improved, but signal processing time increases
Solution Approach 1:
The patent implements pre-configured conversion rules and protocols stored in the signal conversion device's memory. The device is pre-programmed with knowledge of multiple vehicle protocols and their corresponding target protocols, allowing it to perform rapid look-up and conversion without real-time analysis. This preliminary preparation of conversion mappings significantly reduces signal processing time while maintaining comprehensive protocol compatibility.

AI summary
A signal conversion device includes a communication circuit and a processor. The processor may convert a first signal into a second signal using at least one of a first protocol, a second protocol different from the first protocol, or any combination thereof, by receiving the first signal using the first protocol from a vehicle through the communication circuit. The processor may also transmit the second signal to an electronic device connected to the vehicle.
