Sebum-Dissolving Electrode Assembly for Accurate PSG Signal Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PSG test devices face challenges in capturing weak electrical signals due to sebum or makeup on the user's scalp, requiring time-consuming preparation and potentially inaccurate results, especially in obese individuals, and there is a need for a device that can induce parasympathetic nerve dominance for easier sleep onset.
Innovation Solution
An electrode member with an adhesion part, electrode, and retention part that dissolves sebum using a solution through a flow channel, allowing for reliable signal capture and application of current to promote sleep, integrated into a head and body orthosis for PSG testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sebum or makeup is present on the user's scalp, then the electrode cannot capture weak electrical signals accurately, but removing sebum or makeup requires time-consuming preparation
Solution Approach 1:
The patent applies preliminary action by incorporating a sebum-dissolving solution that automatically removes sebum and makeup from the scalp before electrode placement. The solution is applied in advance through a built-in delivery mechanism, eliminating the need for manual cleaning preparation and ensuring the electrode surface is ready for accurate signal capture without time-consuming manual intervention.
Solution Approach 2:
The device performs self-service by automatically delivering and applying the sebum-dissolving solution through an integrated dispensing system. The electrode assembly itself carries and applies the cleaning solution, eliminating the need for external preparation steps or additional devices, thereby reducing preparation time while maintaining measurement precision.
2Measurement precision
If sebum or makeup is present on the user's scalp, then the electrode cannot capture weak electrical signals accurately, but manual removal of sebum increases labor cost
Solution Approach 1:
The patent merges the sebum-removal function with the electrode assembly by integrating a sebum-dissolving solution reservoir and delivery mechanism directly into the electrode structure. This combination eliminates the need for separate manual cleaning procedures, reducing labor requirements and simplifying the overall preparation process while ensuring accurate signal capture.
Solution Approach 2:
The electrode assembly performs self-service by automatically delivering and applying the sebum-dissolving solution to the scalp surface. This self-contained system eliminates the need for external manual intervention or complex preparation procedures, thereby reducing labor costs and simplifying the device operation while maintaining measurement precision.
3Measurement precision
If a PSG test is performed with sebum on the scalp, then the test results may be inaccurate, but repeated testing increases cost
Solution Approach 1:
The patent applies preliminary action by automatically removing sebum and makeup from the scalp using an integrated sebum-dissolving solution before electrode attachment. This preliminary cleaning step ensures that the first PSG test yields accurate results, eliminating the need for repeated tests and thereby reducing the energy and financial costs associated with multiple testing sessions.
Solution Approach 2:
The device performs self-service by automatically delivering and applying the sebum-dissolving solution through its integrated dispensing system. This ensures reliable signal capture from the first test, preventing the need for costly repeated testing and reducing overall energy consumption and financial expenditure while maintaining high measurement precision.
