Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine-learning based recognition systems are trained for all potential errors and anomalies, then detection reliability is improved, but resource consumption and training time increase significantly
Solution Approach 1:
The system performs preliminary actions by defining expected recognition results for normal operational contexts before actual inspection occurs. The context information (time, location, operational parameters) is pre-established with expected outcomes, allowing the recognition system to compare actual results against these pre-defined expectations without requiring comprehensive training on all possible error modes.
Solution Approach 2:
The system changes the approach from training on error parameters to training on context parameters. Instead of training the recognition module to identify all possible errors, it trains the system to understand normal operational contexts and their expected recognition results, then detects anomalies by comparing actual results against these contextual expectations.
2Measurement precision
If comprehensive error training is performed for all possible anomalies, then detection precision is improved, but training time becomes excessively long
Solution Approach 1:
The system establishes expected recognition results for various contexts in advance, creating a reference framework before actual inspection. This preliminary setup allows the system to achieve high detection precision by comparing actual recognition results against pre-defined contextual expectations, eliminating the need for lengthy comprehensive error training.
Solution Approach 2:
The context-based expected results serve multiple functions: they act as training data, as reference standards for comparison, and as adaptive thresholds for anomaly detection. This multi-functional approach allows the system to achieve comprehensive error detection capability without requiring separate training processes for each error type.
3Measurement precision
If extensive training data for every erroneous situation is collected, then recognition accuracy is improved, but data requirements and storage needs increase
Solution Approach 1:
The system fundamentally changes the nature of training data from extensive error examples to compact context definitions with expected results. Instead of collecting vast amounts of data for each error type, the system stores contextual parameters and their corresponding expected recognition outcomes, dramatically reducing data quantity while maintaining recognition accuracy through contextual comparison.
Solution Approach 2:
The system creates simplified copies of error detection capability through context-based expected results rather than using full comprehensive training datasets. These contextual expectations serve as lightweight proxies that capture the essential detection logic without requiring the full complexity of extensive training data for every possible error scenario.
4Reliability
If the recognition module is trained for complex error scenarios, then detection capability is improved, but device complexity increases making edge deployment impossible
Solution Approach 1:
The system changes the complexity distribution by moving from complex error classification logic to simple contextual parameter matching. The recognition module only needs to compare actual recognition results against pre-defined contextual expectations, which are stored as simple parameter sets rather than complex decision trees or neural network weights, enabling deployment on resource-constrained edge devices.
Solution Approach 2:
The system extracts the essential detection logic from complex trained models and represents it as standalone context information with expected results. This extraction separates the detection knowledge from the computational complexity, allowing the core detection capability to be deployed on edge devices while the complex contextual definitions can be updated without retraining the recognition module.

AI summary
A system (1) for examining an object (2) for errors comprises a monitoring device (3), a processing module (5), a capturing device (4) and a recognition module (6). The monitoring device (3) is designed to monitor at least one parameter. A specified range of the parameter defines a context within which a result of a recognition of at least parts of the object (2) is expected. The processing module (5) is designed to prove whether the monitored parameter is within the specified range and in this case to trigger the capturing device (4) which is designed to capture input data associated with the object (2). The recognition module (6) is pre-trained for recognizing the object (2) and to perform the recognition based on the input data. The recognition module (6) is designed to detect an error if a result of the recognition is not corresponding to the expected result.
