Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrode holder structures in EEG caps are cumbersome, difficult to mount and dismount, and require separate adjustments for wire positioning, with single-layer snapping and complex wiring configurations.
Innovation Solution
An electrode holder structure featuring a base with multiple clamping jaws forming an accommodation area, allowing for the secure clamping of stimulating and collecting electrodes, enabling flexible angle adjustment and stacking of electrode holders, and improved wire arrangement through concentric through holes for enhanced conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer snapping structure with one snap is used for the electrode holder, then the structure is simple, but angle switching becomes inconvenient and flexibility is reduced
Solution Approach 1:
The electrode holder structure is divided into multiple layers with multiple snaps (first snap, second snap, third snap) distributed at different positions and heights. This segmentation allows independent adjustment of each snap to achieve different mounting angles, resolving the contradiction between structural simplicity and angle switching flexibility.
Solution Approach 2:
The patent introduces a vertical dimension by positioning snaps at different heights (first snap at first height, second snap at second height, third snap at third height). This multi-dimensional arrangement enables angle switching without increasing horizontal complexity, allowing the electrode holder to achieve versatile positioning while maintaining a compact structure.
2Reliability
If a wet electrode EEG cap with detachable electrode and protruding fixing bolt is used, then the electrode can be securely mounted, but the structure becomes complex and difficult to mount and dismount
Solution Approach 1:
The patent combines multiple fixing functions into an integrated structure where the electrode holder body incorporates multiple snaps that engage with corresponding structures on the electrode cap. This merging eliminates the need for separate protruding fixing bolts and simplifies the mounting process while maintaining secure attachment through multiple engagement points.
Solution Approach 2:
The electrode holder structure is designed with multi-functional snaps that simultaneously provide mounting security, angle adjustment, and easy release capabilities. Each snap serves multiple purposes: securing the electrode, enabling angle switching, and facilitating quick dismounting when activated, thus improving ease of operation without compromising reliability.
3Device complexity
If wiring position is single and requires separate adjustment each time, then the wiring structure is simple, but the process becomes time-consuming and productivity is reduced
Solution Approach 1:
The patent pre-positions multiple wiring positions and snaps during the manufacturing process, with each snap corresponding to predetermined wiring locations. This preliminary arrangement eliminates the need for separate adjustment of wiring positions during mounting, allowing operators to quickly connect wires to pre-designated positions without time-consuming alignment, thus improving productivity while maintaining simple wiring structure.

AI summary
The present disclosure relates to electrode holders and discloses an electrode holder structure and an electroencephalogram (EEG) cap, comprising a base, where multiple clamping jaws are disposed circumferentially, thereby enclosing an accommodation area; an electrode holder, disposed in the accommodation area and fixedly clamped by multiple clamping jaws to form the electrode holder structure. Multiple clamping jaws are disposed circumferentially around the base, and at least one electrode holder is disposed in the multiple layers of accommodation areas formed by multiple clamping jaws, so as to realize stacking disposal of the electrode holder and the seat and improve the entire generality.
