Solution Overview

Problem

Existing wearable bio-electrical monitoring devices cause skin irritation due to the need for direct attachment and frequent detachment for charging, which is exacerbated by the small size and energy efficiency requirements of these devices.

Innovation Solution

A retaining device with a baseplate and adhesive layer that minimizes skin contact area through ventilation, allowing for reversible attachment and detachment without removing the adhesive, featuring a holding frame with apertures and a snap-on hook or magnet for secure retention, enabling simultaneous use and charging of multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the monitoring device is attached adhesively to the skin for long term monitoring, then the monitoring can be continuous and discreet, but the attachment and detachment causes irritated skin

Engineering Contradiction:

Improvemonitoring durationVSAvoidskin irritation

Core Design Contradiction:

Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The device is segmented into a monitoring unit and a separate adhesive patch. The adhesive patch remains attached to the skin while the monitoring unit can be detached for charging, eliminating the need to repeatedly remove and reapply adhesive to the skin.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An adhesive patch serves as an intermediary between the skin and the monitoring unit. The patch stays on the skin while the monitoring unit attaches to and detaches from the patch, protecting the skin from direct repeated adhesive application.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Area of moving object

If the monitoring device is made as small as possible to be discreet, then the device is more comfortable to wear, but the energy storage capacity is limited requiring frequent charging

Engineering Contradiction:

Improvedevice sizeVSAvoidenergy storage capacity

Core Design Contradiction:

Area of moving objectVSUse of energy by moving object

Solution Approach 1:

The system is divided into a small wearable monitoring unit and a separate larger battery/charging unit. This allows the monitoring device to remain small and discreet while the energy storage capacity is distributed to a separate component that can be charged independently.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the baseplate covers the same area as the monitoring device, then the retention is maximized, but the skin ventilation is reduced causing increased irritation

Engineering Contradiction:

Improveretention stabilityVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The baseplate is designed with non-uniform structure featuring apertures that create different local qualities - solid areas for retention and open areas for ventilation. This allows different regions of the baseplate to serve different functions: retention stability and skin breathability.

Inventive Principle:

Principle #3Local quality

4Use of energy by moving object

If the monitoring device requires direct attachment to the skin for charging, then the energy transmission is efficient, but the frequent attachment and detachment increases skin irritation

Engineering Contradiction:

Improveenergy transmission efficiencyVSAvoidskin irritation

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The adhesive patch acts as an intermediary layer between the skin and monitoring device. The patch remains continuously attached to the skin while the monitoring device attaches to and detaches from the patch for charging, eliminating direct repeated adhesive contact with the skin.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A retaining device for retaining a wearable monitoring device for gathering a bio-electrical signal from a body region of a person. The retaining device has a holding frame having a baseplate and retaining mechanism for reversibly retaining the monitoring device onto the baseplate, and preferably an adhesive layer attached at least to a part of the baseplate for fixation of the holding frame onto the skin of the person. An area covered by the baseplate is reduced with respect to an area covered by the monitoring device for ventilation of the skin during wearing the monitoring device.
