Solution Overview
Problem
Existing EEG devices for personal use lack the spatial component, making it difficult to measure brain activity in regions other than the forehead, and are impractical for versatile use due to their design, limiting their application and accessibility.
Innovation Solution
A device with a support that can be removably attached to various accessories like audio headsets, allowing for autonomous operation and flexible placement over the head, enabling measurement and stimulation of brain activity while maintaining contact with the scalp without the need for adhesive electrodes, thus enhancing usability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If EEG devices use fixed support structures (headbands, helmets) with integrated sensors, then the spatial coverage of brain regions can be improved, but the device complexity and difficulty of handling increase
Solution Approach 1:
The device separates the sensor module from the support structure, allowing the sensors to be distributed across multiple removable components that can be attached to different areas of the head (forehead, temples, occipital region), thereby achieving comprehensive spatial coverage without requiring a complex integrated helmet structure
Solution Approach 2:
The support structures (headbands, clips) are designed as universal, reusable components that can be combined with different sensor modules and used across multiple measurement sessions, reducing overall device complexity while maintaining versatile spatial coverage
2Area of stationary object
If sensors are permanently integrated into the headset support, then the spatial coverage is improved, but the adaptability and ease of use decrease
Solution Approach 1:
The sensor module is segmented from the support structure, allowing users to attach and detach sensors from different support configurations (headbands, clips, headphones) depending on the measurement needs and comfort requirements, thereby enhancing adaptability while maintaining spatial coverage
Solution Approach 2:
The device transitions from a static, fixed configuration to a dynamic, reconfigurable system where sensor modules can be moved between different support structures and head positions, enabling adaptability across various usage scenarios while preserving comprehensive brain region coverage
3Measurement precision
If adhesive electrodes are used for direct contact with the scalp, then the measurement precision is improved, but the ease of operation and comfort deteriorate
Solution Approach 1:
The invention extracts the adhesive component from the electrode system, replacing it with non-adhesive contact elements that attach to the scalp through mechanical means (clips, springs, elastic bands) rather than adhesive, thereby eliminating the complexity of application and removal while maintaining measurement precision through secure contact
Solution Approach 2:
The device employs self-adhering or self-adjusting mechanisms (elastic bands, spring-loaded clips) that automatically maintain appropriate contact pressure with the scalp without requiring external adhesive materials or specialized application procedures, improving ease of operation while preserving measurement quality
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a practical and easy-to-use solution for measuring and stimulating brain activity, allowing for extended use periods and adaptability to different situations without disturbing others, while maintaining comfort and discretion.
Implementation Method 1
A device for measuring brain electrical activity (or electroencephalograph) makes it possible to monitor the global activity of large groups of neurons in the brain
Implementation Method 2
Cerebral photonic stimulation, or photo neuromodulation, is based on the fact that the absorption of photons causes photochemical reactions in an individual's neurons and alters their activity
Implementation Method 3
Non-invasive (or minimally invasive) brain magnetic stimulation is called TMS (Transcranial Magnetic Stimulation): this technique consists of generating a magnetic field through an antenna on the surface of the stimulated individual's brain. This will induce electrical micro-currents in the brain region under the antenna (electromagnetic induction principle)

AI summary
A device for measuring and/or stimulating a brain activity, preferably an EEG device, including a transmitter and/or detector for transmitting and/or detecting physiological signals produced by the brain of an individual, and a support for the transmitter and/or detector, wherein the support is configured to extend over the top of the individual's head, the support removably attachable to an accessory intended to be worn by the individual, on his or her head, such as an audio headset, the support being configured such that, when the device is worn by the individual, the transmitter and/or detector are held in substantially close contact with the individual's head by the accessory.
