Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional non-portable EEG collection methods are used, then measurement precision can be maintained, but portability and ease of operation deteriorate
Solution Approach 1:
The patent replaces traditional wired, mechanically-connected EEG systems with a wireless, battery-powered portable device that uses electromagnetic fields for data transmission, eliminating physical constraints and enabling ambulatory use while maintaining measurement capabilities
Solution Approach 2:
The portable EEG device integrates multiple functions including EEG signal acquisition, wireless communication, battery power supply, and data processing into a single unit, making it suitable for both clinical and ambulatory applications
2Reliability
If traditional EEG collection methods are used, then stable sensor contact can be achieved, but device intrusiveness and comfort deteriorate
Solution Approach 1:
The patent employs flexible, thin-film electrode materials that can conform to the contours of the head, providing stable electrical contact while being comfortable and non-intrusive for extended wear during daily activities
Solution Approach 2:
The device uses adjustable contact pressure parameters and flexible material properties to optimize both the stability of sensor contact and the comfort level, allowing the system to adapt to different users and wearing conditions
3Measurement precision
If traditional EEG collection methods are used, then data accuracy can be maintained, but stability during body motion deteriorates
Solution Approach 1:
The patent incorporates dynamic stabilization mechanisms including flexible mounting structures and motion compensation algorithms that adapt to body movements, maintaining stable sensor contact and accurate EEG measurements during ambulatory activities
Solution Approach 2:
The device uses counterbalancing design elements and flexible mounting systems that compensate for motion-induced displacements, maintaining consistent sensor positioning relative to the head despite external movements
