Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If EEG monitoring devices are integrated into eyewear with fixed structural configuration, then the device structure is simplified and manufacturing is easier, but the device cannot be easily adapted to individual head sizes and causes discomfort
Solution Approach 1:
The EEG monitoring system is divided into separate components: a fixed eyewear frame and removable temple adapters. The adapters can be detached and reattached, allowing different configurations to be used with the same base frame. This segmentation enables the main frame to be manufactured with standardized dimensions while the adapters can be customized or adjusted to fit individual users' head sizes and preferences.
Solution Approach 2:
The temple adapters incorporate adjustable elements that allow dynamic modification of the device to suit different users. The adapters can be positioned at various locations on the temple and may include adjustable clamps or flexible components that adapt to individual head shapes and sizes, transforming a static fixed-structure device into a dynamically adaptable one.
2Device complexity
If EEG electrodes are fixed in position on eyewear, then device structure is simpler, but signal quality deteriorates due to poor fit and discomfort
Solution Approach 1:
The electrode positioning system is segmented into the fixed eyewear frame and the removable temple adapters that contain the electrodes. This allows the electrodes to be positioned on the adapters rather than being permanently fixed to the frame, enabling optimization of electrode placement for both signal quality and user comfort while keeping the overall device structure relatively simple.
Solution Approach 2:
The temple adapters serve as intermediary components between the fixed eyewear frame and the EEG electrodes. They provide a flexible interface that can be adjusted to achieve optimal contact between the electrodes and the user's head, thereby improving signal quality without requiring complex integrated electrode mounting structures.
3Adaptability or versatility
If EEG monitoring device is built into specific eyewear, then integration is achieved, but the eyewear cannot be easily replaced and user acceptance decreases
Solution Approach 1:
The system is segmented into a reusable base eyewear frame and interchangeable temple adapters containing the EEG monitoring components. Users can replace the entire adapter assembly if they wish to change eyewear styles, while the base frame can be retained. This segmentation provides flexibility in eyewear replacement without requiring complete redesign of the integrated EEG system.
Solution Approach 2:
The base eyewear frame is designed as a universal platform that can accommodate different temple adapters. This universality allows the same frame to be used with multiple adapter configurations, enabling users to replace or upgrade components without discarding the entire eyewear system, thereby reducing overall device complexity while maintaining flexibility.

AI summary
Presented is an EEG adapter device for eyewear which can be worn invisibly and continuously by the user. The eyewear adapter includes a main body configured in the form of a sleeve so that an intended temple of the eyewear can slidably fit therein, a ring configured to fit over the eyewear's temple and operable by a user to move a first EEG electrode of the eyewear adapter toward or away from the main body to ensure the first EEG electrode is adjustably positioned at FT9/FT10 of the 10-10 system. The eyewear adapter further includes a second EEG electrode and positioned in the vicinity of a bony region behind the user's ears, a third EEG electrode positioned at T9/T10 position of the 10-10 system when in use, and an electronics unit configured to receive and process EEG-related data from the first, the second, and the third EEG electrodes.
