Solution Overview

Problem

Existing garment-based ECG monitoring solutions face issues such as non-compliance, incorrect application, skin sensitivity to adhesives, and non-traditional ECG waveforms due to electrode movement during patient activity, which affect signal quality and require clinician re-training or AI interpretation.

Innovation Solution

A garment with electrodes that can move linearly and rotationally relative to the body, connected by wires in channels or elastic straps, ensuring contact with the skin without adhesives, and featuring adjustable fit and easy application mechanisms to maintain diagnostic-quality signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If electrodes are inflexibly attached to the garment, then the garment structure is simple and manufacturing is easy, but the electrodes slide across the skin surface during patient movement causing non-traditional ECG waveforms

Engineering Contradiction:

Improveease of electrode attachmentVSAvoidECG waveform quality

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent makes the electrode attachment dynamic by allowing the electrodes to move independently relative to the garment through holes in the lining. This dynamic configuration enables the electrodes to adapt to skin movement while maintaining proper contact, resolving the contradiction between simple attachment and waveform quality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the electrode system from the garment structure by creating holes in the lining that allow electrodes to be suspended independently. This segmentation allows the electrodes to move with the skin while the garment moves independently, maintaining both manufacturing simplicity and ECG signal quality.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If electrodes are placed in areas of the body where the skin will move less during movement, then electrode sliding is minimized, but the ECG waveforms are affected and require clinician re-training or AI interpretation

Engineering Contradiction:

Improveelectrode position stabilityVSAvoidECG waveform interpretability

Core Design Contradiction:

Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The patent allows electrodes to move dynamically with the skin through holes in the garment lining, maintaining traditional ECG placement on movable body surfaces. This dynamic adaptation preserves both position stability relative to the skin and waveform interpretability, avoiding the need for clinician re-training.

Inventive Principle:

Principle #15Dynamics

3Reliability

If adhesive is used to attach electrodes to skin, then electrode contact is secure, but skin irritation and sensitivity issues occur

Engineering Contradiction:

Improveelectrode contact reliabilityVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the adhesive component from the electrode attachment system entirely. By suspending electrodes through holes in the garment lining and using compression force from the fitted garment, the system achieves reliable contact without adhesives, eliminating skin irritation while maintaining electrical contact.

Inventive Principle:

Principle #2Taking out (Extraction)

4Reliability

If garment fits snugly to maintain electrode contact, then electrode-skin contact is maintained, but movement and blood flow are restricted causing patient discomfort

Engineering Contradiction:

Improveelectrode contact maintenanceVSAvoidpatient comfort and movement freedom

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent creates a dynamic system where the garment fits snugly to maintain electrode contact through compression, while the electrodes themselves can move independently through holes in the lining. This allows the garment to provide necessary compression without restricting patient movement or blood flow, maintaining both contact reliability and comfort.

Inventive Principle:

Principle #15Dynamics

5Adaptability or versatility

If traditional sticky electrodes with wires are used, then electrode placement is flexible, but patients feel tethered and cannot move freely

Engineering Contradiction:

Improveelectrode placement flexibilityVSAvoidpatient mobility freedom

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the electrode support function into the garment structure itself, with electrodes suspended through holes in the lining and wires contained in channels or pockets. This integration eliminates the tethered feel of external wires while maintaining placement flexibility, allowing patients to move freely.

Inventive Principle:

Principle #5Merging (Combining)
