Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple discrete control modules are implemented to manage different data links and protocols, then system functionality and protocol support are improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The patent consolidates multiple discrete control modules into a single gateway device that handles multiple data links and protocols simultaneously. The gateway integrates functionality that would otherwise require separate modules, reducing system complexity while maintaining protocol support through a unified architecture with centralized message routing and proxy control capabilities.
Solution Approach 2:
The gateway is designed as a universal control module capable of interfacing with multiple different data link types and protocols through a single device. It provides multi-functional support for various communication standards including J1939, CAN, LIN, and proprietary protocols, eliminating the need for specialized modules for each protocol type.
2Adaptability or versatility
If interface devices are added to facilitate communication between different data links, then communication compatibility is improved, but hardware requirements and space consumption increase
Solution Approach 1:
The patent merges multiple interface device functions into a single gateway unit that can simultaneously support multiple data link interfaces. Instead of adding separate interface devices for each protocol, the gateway integrates all interface capabilities in one consolidated hardware platform, reducing the total quantity of hardware components required.
3Adaptability or versatility
If specialized components are implemented for each data link type, then communication capability is improved, but system integration and maintenance cost increase
Solution Approach 1:
The gateway is designed as a universal platform that supports multiple data link types through integrated software and hardware capabilities. It can accommodate J1939, CAN, LIN, and proprietary protocols within a single device architecture, simplifying system integration by providing a standardized interface layer that handles protocol-specific requirements centrally rather than requiring separate specialized components for each protocol.

AI summary
Methods and systems of the present invention are provided for performing proxy control functions in an environment including one or more work machines. Such methods and systems may leverage one or more gateways to serve as a proxy for one or more distinct modules. A gateway, located in a work machine, may be programmed with proxy logic that performs functions associated with certain modules used in a work machine environment. The gateway may monitor a data link and retrieve broadcasted messages. The broadcasted messages may include source and/or destination module address identifiers. The gateway may retrieve messages from the data link based on a determination that the message is destined for a module for which the gateway serves as a proxy. The gateway may route a retrieved message, using a mapping structure, to the appropriate proxy logic that performs functions associated with the destination module.
