Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EEG headsets are often bulky, uncomfortable, and lack adjustability, leading to discomfort due to excessive pressure and inadequate fit for varying head sizes and shapes, which compromises the accuracy and reliability of neuro-response data collection.
Innovation Solution
A portable EEG headset with independently adjustable and removable strips attached to a headband, featuring magnetic fasteners for secure electrode placement and easy adjustment, ensuring comfortable fit and effective noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing EEG headsets use fixed and bulky structures, then electrode placement is simplified, but comfort and adaptability to varying head sizes and shapes deteriorate
Solution Approach 1:
The headset is divided into multiple independent strips, each with its own electrodes and fastening mechanism. These strips can be independently adjusted and positioned to accommodate different head sizes and shapes while maintaining simple electrode placement procedures.
Solution Approach 2:
The headset incorporates adjustable and removable strips that can be dynamically configured to fit different head geometries. The magnetic fasteners allow for easy adjustment and repositioning, enabling the device to adapt to varying head sizes and shapes without compromising electrode placement simplicity.
2Stability of the object's composition
If existing EEG headsets use fixed and bulky structures, then structural stability is improved, but comfort and user wearability deteriorate
Solution Approach 1:
The headset is segmented into multiple independent strips rather than a single bulky structure. This segmentation reduces overall bulk while maintaining structural stability through distributed support points and magnetic fastening mechanisms that secure each strip independently.
Solution Approach 2:
Traditional mechanical fastening systems are replaced with magnetic fasteners that provide secure attachment without requiring complex mechanical structures. This substitution reduces the bulk of the headset while maintaining structural stability and improving comfort through easier adjustment and removal.
3Reliability
If existing EEG headsets apply excessive pressure for secure fit, then electrode contact reliability is improved, but user comfort and safety deteriorate
Solution Approach 1:
Mechanical pressure-based fastening is replaced with magnetic attraction forces. The magnetic fasteners provide secure electrode contact and reliable attachment without requiring excessive pressure, thereby maintaining electrode contact reliability while significantly improving user comfort and safety.
