Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for treating vascular dementia, such as pharmacological treatments and invasive vagus nerve stimulus, are either ineffective or invasive, making them unsuitable for non-invasive and detachable cognitive function recovery.
Innovation Solution
A stimulus applying apparatus comprising stimulus applying units and a housing that can be easily coupled and removed from a target area, utilizing magnetic attractive forces to secure the apparatus and incorporating a control unit, battery, and stimulating electrodes to apply electrical stimuli.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a band-shaped electrode assembly is used to apply stimulus, then the stimulus can be applied to body parts, but it is difficult to apply to body parts where it is difficult to wear
Solution Approach 1:
The electrode assembly is divided into multiple detachable electrodes rather than a single band-shaped structure. Each electrode can be independently attached to different body parts, enabling application to areas that cannot accommodate traditional bands while maintaining stimulus delivery capability
Solution Approach 2:
The invention transitions from a two-dimensional band structure to a three-dimensional detachable electrode system with housings that can be positioned in various orientations and configurations, allowing adaptation to complex body surface geometries that bands cannot accommodate
2Reliability
If invasive vagus nerve stimulus technology is used, then cognitive dysfunction can be treated, but it is invasive and difficult to apply in most cases
Solution Approach 1:
The invention uses surface electrodes as an intermediary to deliver neural stimulation without direct nerve invasion. The electrodes apply electrical fields through the skin to stimulate the vagus nerve indirectly, achieving therapeutic effects while avoiding surgical implantation and its associated risks
Solution Approach 2:
The invention replaces the mechanical invasive approach of surgical nerve stimulation with a non-invasive electrical field-based stimulation method. Electrical fields are applied through surface electrodes to achieve neural modulation without physical penetration or surgical intervention
3Object-affected harmful factors
If a detachable stimulus applying apparatus is used, then risks associated with invasive procedures are reduced, but the apparatus must be easily attachable and removable
Solution Approach 1:
The electrode housings incorporate magnetic members that enable dynamic attachment and detachment through magnetic attraction and repulsion. The magnetic mechanism allows the housings to be easily attached to corresponding magnetic bases without tools and removed when needed, providing operational flexibility while maintaining secure positioning during use
