Solution Overview

Problem

Current wound closure methods, such as sutures and staples, are time-consuming, traumatic, and can lead to scarring and infection if not properly managed, and existing magnetic devices are complex or not adaptable to various wound shapes and sizes.

Innovation Solution

A magnetic wound closure device with elongated magnets and a removable sheet that separates the magnets initially, allowing precise placement before magnetic attraction to reapproximate wound edges, eliminating the need for anesthesia and reducing trauma, with adaptable sizes and shapes for different wounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional sutures or staples are used for wound closure, then wound edges can be reapproximated effectively, but the procedure becomes time-consuming and traumatic requiring anesthesia

Engineering Contradiction:
Improvewound closure effectivenessVSAvoidclosure procedure time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical suturing/stapling system with a magnetic attraction system. Magnets embedded in adhesive patches create magnetic forces that draw wound edges together, eliminating the need for needles, threads, or metal staples and their associated trauma and time-consuming procedures

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic fields as an intermediary force to achieve wound closure. Instead of direct mechanical contact between surgeon and wound tissue, magnetic forces serve as the mediating mechanism to attract and approximate wound edges from a distance

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If magnets are placed directly on wound edges without separation, then magnetic attraction occurs immediately, but precise placement becomes difficult and magnets cannot be positioned accurately on opposite sides

Engineering Contradiction:
Improvemagnet placement easeVSAvoidmagnet placement precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent divides the magnetic closure system into separate components: individual magnets are embedded in separate adhesive patches that can be independently positioned on opposite sides of the wound. This segmentation allows precise placement of each magnet before activation, solving the placement precision problem

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary placement of magnets in their final positions using adhesive patches before activating magnetic attraction. The magnets are pre-positioned accurately on opposite sides of the wound while separated, then the separation barrier is removed to initiate closure

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If flexible magnetic devices are used for non-linear or curved wounds, then adaptability improves, but device complexity increases

Engineering Contradiction:
Improvewound shape adaptabilityVSAvoidmagnetic device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses flexible adhesive patches as the carrier for magnets. These thin, flexible films can be conformally applied to various wound shapes including non-linear and curved surfaces, providing adaptability without requiring complex rigid magnetic structures

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent employs disposable adhesive patches with embedded magnets that are single-use. Each patch is simple in structure but effective for its intended use, eliminating the need for complex reusable devices while maintaining versatility for different wound configurations

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

A wound closure device using magnets to draw skin together. When two skin adhering magnets are placed on opposite sides of a wound in a polar opposite configuration, the magnets attract each other, thus drawing the skin underneath the magnets together and reapproximating wound edges. The device includes a removable sheet having an elongated partition member that separates the first magnet from the second magnet. When the removable sheet and elongated partition member are removed from the magnets, the removal allows the magnets to draw in close together to reapproximate wound edges. To prevent slippage of the magnets, the inner edges of each magnet may have complementary notches and protrusions that align with each other, thereby preventing longitudinal movement of the magnets along their inner edges.
