Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual button or DTC-triggered recording is used, then recording can be initiated, but control and quality of recording are reduced
Solution Approach 1:
The patent applies parameter changes by allowing users to define multiple recording trigger conditions with different parameters (DTC settings, operational parameters, environmental conditions). This enables the system to adapt recording initiation to specific diagnostic needs, improving both ease of operation and recording quality through customized parameter selection.
Solution Approach 2:
The system implements dynamics by transitioning from static, fixed trigger methods to dynamic, multi-condition trigger mechanisms. The recording system can now respond to various changing conditions including operational states, environmental factors, and combinations thereof, making the recording initiation both easier and more reliable.
2Loss of information
If comprehensive data recording is performed, then more diagnostic information is captured, but data analysis complexity increases
Solution Approach 1:
The patent applies the extraction principle by selectively capturing only the diagnostic information relevant to specific trigger conditions. Instead of recording all possible data continuously, the system extracts and records only data associated with defined triggers, reducing information loss while simultaneously simplifying analysis by eliminating irrelevant data.
Solution Approach 2:
The system implements local quality by applying different recording characteristics to different trigger conditions. Each trigger can have its own customized data set and recording parameters, ensuring high-quality capture of specific diagnostic information while avoiding the complexity of uniform comprehensive recording across all conditions.
3Measurement precision
If multiple trigger conditions are defined, then recording accuracy improves, but system configuration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the trigger condition configuration into modular, independent elements. Users can define multiple discrete trigger conditions that can be selectively activated, allowing precise recording control without requiring complex interconnected configurations. Each trigger condition stands alone as a configurable unit.
Solution Approach 2:
The system implements universality by creating a standardized trigger condition framework that handles multiple types of conditions (DTC, operational, environmental) through a common configuration interface. This multi-functional approach allows diverse trigger types to be managed uniformly, improving recording accuracy while minimizing configuration complexity.
