Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data is transmitted unchanged from motor vehicle control device to data processing device, then device complexity is reduced, but real-time processing capability and data reliability deteriorate
Solution Approach 1:
The influencing device performs preliminary actions by checking and manipulating data values before they reach the data processing device. This includes validating data formats, checking plausibility, and preparing data in the required format in advance, thereby improving real-time processing capability without significantly increasing overall system complexity.
Solution Approach 2:
The influencing device acts as an intermediary between the motor vehicle control device and the data processing device. It mediates data transmission by performing validity checks, format conversions, and manipulations, thereby enhancing data reliability and real-time processing while maintaining manageable system complexity through a dedicated intermediate component.
2Ease of operation
If data is transmitted without preprocessing, then ease of operation is improved, but data reliability and accuracy deteriorate
Solution Approach 1:
The system implements self-service by automatically performing validity checks, format validations, and data manipulations in the influencing device without requiring manual intervention. This maintains ease of operation while significantly improving data reliability through automated quality assurance mechanisms.
Solution Approach 2:
The influencing device implements feedback mechanisms by checking data validity and providing information about data quality to the data processing device. This feedback loop ensures that only valid and accurate data is processed further, thereby improving data reliability while maintaining operational simplicity through automated validation.
3Reliability
If comprehensive data checks and manipulations are performed in influencing device, then data reliability is improved, but device complexity increases
Solution Approach 1:
The data processing functionality is segmented into distinct modules within the influencing device, including separate units for format checking, validity verification, data manipulation, and transmission control. This segmentation improves data reliability through comprehensive checks while managing device complexity by organizing functions into manageable, independent modules.
4Productivity
If data is processed and manipulated in real-time, then productivity is improved, but device complexity and computational requirements worsen
Solution Approach 1:
The influencing device performs partial processing actions by focusing on essential checks and manipulations required for real-time operation. It performs format validation, basic validity checks, and necessary data transformations, while more complex analyses are deferred to the data processing device, thereby improving real-time productivity without excessive computational complexity.

AI summary
The method involves obtaining a value from a memory of influencing apparatus (10) and from a memory (13) of motor vehicle control apparatus (11), based on specific address. The association of the addresses or selected value with the subfunctions is checked. The specific subfunction is called on presence of valid association. The selected value is checked or manipulated based on the called subfunction. The value is transferred to the motor vehicle control apparatus or data processing apparatus (12) based on the checked result.
