Solution Overview

Problem

Existing ostomy appliances lack effective monitoring systems to determine the operating state, leading to premature or late changes, which can cause skin damage, leakage, and increased material waste.

Innovation Solution

An ostomy system with a base plate equipped with electrodes and sensors, connected to a monitor device, allows for real-time monitoring of adhesive properties and operating state, enabling timely adjustments to prevent skin damage and leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single monitoring protocol is used for all users, then device complexity is reduced, but measurement precision and reliability deteriorate due to inability to account for individual anatomical variations

Engineering Contradiction:
Improvemonitoring system complexityVSAvoidwaist circumference measurement precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system dynamically adjusts monitoring parameters and protocols based on user-specific anatomical characteristics. Different user types (e.g., different body shapes, ostomy locations) receive customized monitoring thresholds, frequency, and methods, allowing the system to adapt its complexity to individual needs rather than using a fixed protocol for all users.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The monitoring system applies different measurement criteria and parameters to different user types based on their specific anatomical features. Each user type has customized monitoring protocols tailored to their local characteristics, such as different waist measurement techniques for different body types, thereby improving measurement precision without requiring complete system redesign.

Inventive Principle:
Principle #3Local quality

2Reliability

If monitoring parameters are customized for different user types, then measurement precision and reliability improve, but device complexity and data processing requirements increase

Engineering Contradiction:
Improvemonitoring data reliabilityVSAvoidsystem configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

User-specific monitoring parameters and protocols are pre-configured and stored in the system database before actual monitoring begins. When a user is registered, their anatomical characteristics are captured and the appropriate pre-defined protocol is automatically selected, eliminating the need for complex real-time configuration and reducing system complexity during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors user responses and measurement data quality, automatically adjusting and optimizing monitoring parameters based on feedback from actual usage. This feedback mechanism allows the system to refine its customized protocols over time, improving reliability while maintaining manageable complexity through data-driven optimization.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If frequent monitoring is performed to improve detection accuracy, then measurement precision improves, but loss of time and user burden increase

Engineering Contradiction:
Improvecondition detection accuracyVSAvoiduser time commitment
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements periodic monitoring with variable intervals based on user type, risk factors, and detected trends. Instead of uniform frequent monitoring, the system schedules measurements at optimized intervals tailored to each user's needs, achieving adequate detection accuracy while minimizing time burden. High-risk periods trigger more frequent monitoring, while stable periods use reduced frequency.

Inventive Principle:
Principle #19Periodic action
