Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current extraction positions are set along a straight line, then the device complexity is reduced, but the measurement precision deteriorates because the curved shape of actual neural pathways cannot be captured
Solution Approach 1:
The system performs preliminary actions by acquiring morphological images (X-ray, CT, MRI) and generating the neural pathway model before current component extraction. This pre-established curved pathway framework enables accurate current extraction that follows the actual neural pathway geometry, resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The patent introduces a morphological image and generated neural pathway as an intermediary between the magnetic field measuring device and the current component extraction process. This intermediary provides the curved pathway information needed for accurate current extraction without requiring direct complex measurement of the neural pathway itself
2Loss of information
If multiple types of biometric information are displayed simultaneously, then the information completeness is improved, but the ease of operation deteriorates due to difficulty in comprehending multiple parameters
Solution Approach 1:
The system segments biometric information display into multiple independent windows, each dedicated to displaying specific current components (intra-axonal current, volume current) or parameters. This segmentation allows complete multi-parameter information to be displayed while making each individual parameter easily comprehensible through dedicated display areas
Solution Approach 2:
The patent transitions from displaying multiple parameters in a single crowded space to distributing them across multiple spatial windows on the display device. This dimensional arrangement in space allows simultaneous presentation of complete biometric information while maintaining ease of operation through organized spatial separation
