Solution Overview

Problem

Current wound treatment systems lack efficient methods for monitoring and managing wound conditions, particularly in terms of fluid properties like pH, humidity, and pressure, which are crucial for effective negative-pressure therapy and wound healing.

Innovation Solution

A system comprising a dressing interface with integrated sensors (pH, humidity, and pressure sensors) and a wireless communication module that allows for real-time data transmission to a therapy device, enabling precise monitoring and adjustment of wound conditions during negative-pressure therapy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors are integrated into the dressing interface for real-time monitoring, then measurement precision and reliability are improved, but device complexity increases

Engineering Contradiction:

Improvefluid property monitoring accuracyVSAvoiddressing interface structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent integrates multiple sensors (pH, humidity, temperature, pressure) directly into the dressing interface, combining monitoring functions that were previously separate into a unified system. This merging approach enables comprehensive fluid property monitoring while managing complexity through integrated design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The dressing interface is designed to perform multiple functions simultaneously: it serves as both the therapeutic dressing and the monitoring platform. The same interface that delivers negative-pressure therapy also houses sensors for pH, humidity, temperature, and pressure monitoring, eliminating the need for separate monitoring devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If wireless communication modules are added to enable data transmission, then information availability is improved, but device complexity and energy consumption increase

Engineering Contradiction:

Improvewound condition data transmissionVSAvoidbattery power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication technology. Instead of requiring physical cables to transmit sensor data from the dressing interface to the external system, the invention uses wireless modules (such as Bluetooth or Wi-Fi) to transmit information electronically through electromagnetic fields, eliminating the need for physical connectors.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If multiple sensors are integrated for comprehensive monitoring, then measurement precision is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvemulti-parameter fluid analysisVSAvoidsensor integration process

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent divides the monitoring system into modular sensor components, each responsible for detecting specific fluid properties (pH, humidity, temperature, pressure). This segmentation allows for standardized manufacturing of individual sensor modules that can be independently tested and assembled, reducing overall manufacturing complexity compared to creating a single integrated multi-functional sensor.

Inventive Principle:

Principle #1Segmentation
