Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual conversion methods are used to convert module configurations between different module definitions, then configuration accuracy can be maintained, but the conversion process becomes laborious and time-consuming
Solution Approach 1:
The system performs automatic self-conversion of module configuration files between different module definitions through automated comparison and conversion processes, eliminating the need for manual intervention while maintaining configuration accuracy through systematic parameter mapping and validation
Solution Approach 2:
The patent replaces manual mechanical conversion processes with automated computer-based systems that use algorithms to compare, analyze, and convert module configuration files, substituting human labor with automated computational methods that are both faster and more precise
2Adaptability or versatility
If all parameters are manually converted during module definition updates, then complete configuration transfer is achieved, but the process becomes excessively complex and time-consuming
Solution Approach 1:
The patent segments the conversion process into distinct phases: automated comparison of module definitions, identification of convertible parameters, automatic conversion of compatible parameters, and separate handling of non-convertible parameters. This segmentation reduces overall process complexity while maintaining complete configuration transfer
Solution Approach 2:
The system performs partial automatic conversion for parameters that can be automatically transferred, while applying different processing logic to non-convertible parameters. This selective approach avoids the complexity of manually processing every single parameter while ensuring complete configuration transfer through appropriate handling of all parameter types
3Productivity
If configuration parameters are reused across different software versions, then development efficiency is improved, but data compatibility issues may arise between different module definitions
Solution Approach 1:
The system implements feedback mechanisms that automatically compare source and target module definitions, identify compatibility issues, and adjust the conversion process accordingly. This feedback loop ensures that reused configuration parameters maintain data compatibility across different software versions while preserving development efficiency
Solution Approach 2:
The patent dynamically adjusts conversion parameters based on the specific characteristics of the source and target module definitions. By changing conversion parameters adaptively, the system enables efficient parameter reuse across software versions while maintaining data compatibility through version-specific conversion settings
Data Source
AI summary
A method for configuring a real or virtual electronic control unit, wherein a control unit software is executed on the control unit, and the control unit software comprises a basic software layer, the basic software layer is configured by a module configuration file by setting values of parameters, the scope of the configurable parameters being defined in a first module definition file which contains the identifiers of the configurable parameters. The first module definition file is replaced by a second module definition file, and a conversion of the first module configuration file into a second module configuration file takes place.
