Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If magnetic field sensing is used to determine position of remote objects, then position information can be obtained, but measurement precision deteriorates due to interference from external magnetic fields
Solution Approach 1:
The patent extracts only the essential geometric characteristics of the magnetic field (spatial geometry) rather than attempting to measure the complete magnetic field vector. By focusing solely on positional information derived from field geometry and ignoring interfering magnetic field components, the system obtains accurate position data while filtering out external interference automatically.
Solution Approach 2:
The patent introduces an intermediate computational step that processes raw magnetic field measurements through geometric characterization algorithms. This intermediary processing layer transforms noisy magnetic field data into clean positional information, effectively filtering out interference from external magnetic fields while preserving the essential position data.
2Measurement precision
If complex computational methods are used to determine position from magnetic field data, then position accuracy can be improved, but device complexity increases
Solution Approach 1:
The patent extracts only the necessary geometric features from magnetic field measurements - specifically the spatial relationships that define position - rather than performing complete magnetic field modeling. This selective extraction of essential geometric information maintains position accuracy while dramatically reducing computational requirements.
Solution Approach 2:
The patent changes the computational approach from solving complex nonlinear magnetic field equations to analyzing simple geometric characteristics of the field. By transforming the problem from one requiring heavy mathematical computation to one based on geometric reasoning, the system achieves high precision with minimal computational complexity.
3Loss of information
If traditional magnetic field modeling is used to locate remote objects, then position can be determined, but loss of time occurs due to computational requirements
Solution Approach 1:
The patent extracts only the critical geometric information needed for position determination from magnetic field measurements, bypassing time-consuming complete field modeling. By focusing exclusively on spatial geometry characteristics that directly indicate position, the system rapidly processes magnetic data with minimal computation time.
Solution Approach 2:
The patent skips the lengthy process of complete magnetic field modeling and solution of nonlinear equations. Instead, it rushes directly to the essential task of geometric characterization, which provides position information much more quickly by eliminating unnecessary computational steps.
