Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the head-worn device encircles a large portion of the head to improve signal capture, then the signal quality improves, but the comfort and wearability deteriorate
Solution Approach 1:
The head-worn device is divided into multiple independent electrode holders positioned at different locations (forehead, temples, back of head) that can function independently or in combination. This segmentation allows the device to capture brain signals from multiple regions without requiring a continuous encirclement, thereby improving signal quality while maintaining comfort and reducing the burden on the wearer's head.
2Adaptability or versatility
If the device structure is made complex to accommodate various undulating shapes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Each electrode holder is designed with specific local characteristics including undulating surfaces, flexible materials, and adjustable positioning mechanisms tailored to its specific location on the head (forehead, temple, occipital region). This local optimization allows each component to adapt to the specific geometry of its placement area, providing overall adaptability to various head shapes without requiring the entire device to be uniformly complex.

AI summary
This invention is a head-worn device (e.g. headband, halo, or headset) with sensors (e.g. electrodes) which record brain activity. In an example, the device can be undulating with concave undulations which rest on the tops of a person's ears. In an example, the device can further comprise right side and left side ear prongs (e.g. arms, segments, or portions) which curve around the posterior and upper surfaces of a person's right and left ears.
