Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine learning is used to detect false cells in a wireless communication network, then detection capability is improved, but memory and processing resources are excessively consumed
Solution Approach 1:
The patent segments the original high-dimensional feature space into multiple lower-dimensional subspaces by identifying and removing redundant features. This segmentation approach maintains the essential detection capability while dividing the computational burden into manageable parts, directly reducing memory and processing resource requirements.
Solution Approach 2:
The patent extracts and removes redundant features from the dataset that do not contribute significantly to false cell detection. By taking out these unnecessary features, the system reduces the dimensionality of the data, thereby decreasing the memory and processing resources needed while preserving the core detection functionality.
2Adaptability or versatility
If the number of valid cell identities in the network increases, then network capacity is improved, but machine learning resource requirements increase
Solution Approach 1:
The patent implements a dynamic feature selection mechanism that adapts to the network's scale. As the number of valid cell identities increases, the system dynamically identifies and removes redundant features, ensuring that resource consumption does not linearly increase with network capacity. This dynamic adaptation maintains efficiency regardless of network size.
Solution Approach 2:
The patent changes the parameter of feature dimensionality by transforming the original high-dimensional feature set into a reduced-dimensional representation. This parameter change allows the system to handle larger numbers of valid cell identities without proportionally increasing memory and processing resource requirements.
3Quantity of substance
If feature dimensionality is reduced, then resource requirements are decreased, but discriminatory power may be compromised
Solution Approach 1:
The patent applies partial action by selectively removing only the redundant features while retaining all essential features needed for accurate false cell detection. This selective approach ensures that discriminatory power is maintained by keeping the necessary features, while still achieving resource reduction through the removal of unnecessary dimensions.
Solution Approach 2:
The patent replaces the mechanical approach of using all original features with a sophisticated feature selection mechanism that identifies and removes redundancies. This substitution uses analytical methods to determine which features contribute to discriminatory power and which can be safely removed, thereby maintaining precision while reducing resource consumption.
