Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple manufacturer-specific event/data recorder systems are deployed across a fleet, then each system can be optimized for its specific manufacturer's requirements, but the complexity of managing multiple incompatible data access, download, and analysis tools increases significantly
Solution Approach 1:
The patent introduces a universal data access interface that acts as an intermediary layer between diverse event/data recorder systems and the analysis tools. This interface standardizes data access protocols, allowing different manufacturer-specific systems to communicate through a common standard, thereby reducing the complexity of managing multiple incompatible tools while preserving the reliability of each manufacturer's optimized system
Solution Approach 2:
The patent creates a universal data access and analysis platform that can interface with multiple different event/data recorder manufacturers through standardized protocols. This universal system performs multiple functions: data access, data download, data analysis, and time synchronization, eliminating the need for separate manufacturer-specific tools for each function
2Ease of operation
If wireless data access tools are implemented for each manufacturer's system, then remote data access capability is improved, but the complexity of wireless hardware implementation increases due to each OEM requiring separate wireless solutions
Solution Approach 1:
The patent implements a universal wireless interface that can communicate with multiple different event/data recorder systems using standardized wireless protocols. This single universal wireless hardware solution replaces the need for multiple manufacturer-specific wireless implementations, maintaining remote data access capability while significantly reducing wireless hardware complexity
3Measurement precision
If manual time offset determination is performed for each device, then data synchronization accuracy can be achieved, but the time and effort required for data synchronization increases significantly
Solution Approach 1:
The patent implements an automated time synchronization system that performs time offset determination automatically without manual intervention. The system uses standardized time synchronization protocols to self-calibrate and align timestamps across multiple event/data recorder systems, maintaining synchronization accuracy while eliminating the time-consuming manual process
