Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle network systems are limited by the restriction of using a single network protocol, preventing data exchange between networks with different protocols, which hinders efficient configuration and maintenance, and requires redesigning one network to match another protocol for data interchange.
Innovation Solution
A gateway device with multiple communication controllers connected to devices via different network protocols (LIN, CAN, FlexRay) and a control unit that interconverts data between these protocols, enabling seamless data exchange among devices using various protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data interchange is required between two network systems using network protocols different from each other, then data exchange capability is improved, but one network system must be redesigned to match the other network protocol
Solution Approach 1:
The patent introduces a gateway device as an intermediary between network systems using different protocols. The gateway includes a control unit that receives data from a first network system using a first protocol, converts the data format to match a second protocol, and transmits it to a second network system. This mediator approach enables data exchange without requiring redesign of the original network systems, as the protocol conversion is handled centrally by the gateway's control unit.
Solution Approach 2:
The control unit performs parameter changes by transforming data according to different network protocols. When receiving data in a first protocol format, the control unit modifies the data parameters (format, structure, encoding) to conform to a second protocol, enabling compatibility between networks using different protocols without physical redesign of the network infrastructure.
2Adaptability or versatility
If multiple network systems with different protocols are applied in a vehicle, then network versatility is improved, but data interchange between networks is restricted
Solution Approach 1:
The gateway device serves as a reliable intermediary that ensures data interchange between multiple network systems using different protocols. The control unit systematically converts data between protocols, providing reliable data exchange while maintaining the diversity of network protocols in the vehicle system.
Solution Approach 2:
The gateway device provides universal data interchange capability across multiple network systems with different protocols. The control unit is designed to handle various protocol conversions, making the gateway a multi-functional component that enables reliable communication between LIN, CAN, FlexRay, and other network systems in the vehicle.
3Adaptability or versatility
If one network system is redesigned to match another network protocol for data interchange, then data exchange is enabled, but maintenance complexity increases
Solution Approach 1:
By using a gateway as an intermediary for protocol conversion, the original network systems maintain their original design and configuration. This eliminates the need to redesign network systems to match different protocols, thereby reducing maintenance complexity as each network system can be maintained independently according to its original specifications.
4Device complexity
If a single network protocol is used for all electronic components, then system simplicity is improved, but the ability to exchange data between diverse networks is limited
Solution Approach 1:
The gateway device acts as a mediator that enables data interchange between diverse networks using different protocols while allowing each network to maintain its own protocol standards. This approach preserves the simplicity of using dedicated protocols for specific electronic components while adding the versatility to exchange data across protocol boundaries through the gateway's protocol conversion capability.
