Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle diagnostic systems are passive, costly, and closed, limiting their adaptability and functionality, especially for specialized vehicles and after-market accessories, and fail to integrate and actively communicate data across different components for coordinated actions.
Innovation Solution
A system and method for active control of external vehicle components, integrating sensors, controllers, and user interfaces to collect, process, and communicate data across components like brake controllers, cameras, and cargo systems, enabling coordinated actions through a master control unit and wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If integrated diagnostic systems are implemented in vehicles, then vehicle diagnostic capability is improved, but system cost increases significantly
Solution Approach 1:
The patent creates a universal communication interface that allows a single OBD port to serve multiple functions: communicating with integrated vehicle diagnostics, after-market accessories, and external devices simultaneously. This multi-functional approach eliminates the need for separate dedicated systems for each function, thereby reducing overall system cost while maintaining comprehensive diagnostic capability.
Solution Approach 2:
The patent segments the diagnostic system into modular components: the existing integrated vehicle diagnostic system, after-market accessories, and external devices, each communicating through a standardized protocol. This segmentation allows independent development and optimization of each component while reducing overall system complexity and cost through standardized interfaces.
2Reliability
If integrated diagnostic systems are implemented in vehicles, then vehicle diagnostic capability is improved, but system adaptability to after-market accessories deteriorates
Solution Approach 1:
The patent implements a universal communication protocol at the OBD port that can simultaneously support integrated vehicle diagnostics and a wide variety of after-market accessories. The system automatically detects and adapts to different device types, enabling the same hardware interface to serve multiple functions including engine diagnostics, trailer braking, cargo management, and more, thereby dramatically improving adaptability without sacrificing diagnostic capability.
3Reliability
If integrated diagnostic systems are implemented in vehicles, then vehicle diagnostic capability is improved, but user accessibility and ease of modification deteriorates
Solution Approach 1:
The patent enables end-users to directly access and modify diagnostic parameters, communication protocols, and system configurations through the OBD interface without requiring manufacturer authorization or specialized tools. Users can programmatically control vehicle functions, integrate custom accessories, and modify system behavior, transforming the system from a closed manufacturer-controlled environment to an open user-accessible platform.
4Device complexity
If passive feedback systems are used for vehicle components, then system simplicity is maintained, but coordinated control and automated response capability deteriorates
Solution Approach 1:
The patent implements active feedback loops where the controller continuously monitors data from multiple sensors and accessories, processes this information, and automatically adjusts system parameters and component operations. For example, the system can monitor tire pressure, trailer brake status, and cargo sensor data, then automatically coordinate responses across all these systems rather than merely displaying separate warning lights, thereby enabling coordinated control while maintaining manageable complexity through centralized intelligence.

AI summary
The present disclosure includes a system, method, and device related to data collection and communication related to after-market and external vehicle systems, such as towing systems, cargo carrying systems, trailer breakaway systems, brake systems, braking control systems, and the like. Data is sensed, processed, shared, and further leveraged throughout the discrete components of the system, and possibly via internet and other communications' links, to effect various beneficial actions with minimal driver/user interaction or intervention. In the same manner, data from the system may be used for diagnostic reasons, safety controls, and other purposes.
