Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional ostomy appliances are used without monitoring mechanisms, then the device structure remains simple, but leakage cannot be detected timely leading to skin damage and user discomfort

Engineering Contradiction:

Improveleakage detection capabilityVSAvoidappliance structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sensor assembly is integrated within the base plate structure, with electrodes and adhesive layers nested between functional layers of the base plate. The monitor device connects to the integrated sensor assembly, creating a compact nested configuration that adds monitoring capability without significantly increasing overall device complexity

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The base plate serves multiple functions: it adheres to the skin, provides structural support, and houses the sensor assembly for leakage detection. The adhesive layer simultaneously provides bonding and electrical contact functions, enabling the system to perform both structural and sensing roles with integrated components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If users replace appliances proactively based on real-time feedback, then skin damage is prevented, but users must monitor the system continuously requiring time and attention

Engineering Contradiction:

Improveskin damage riskVSAvoiduser monitoring time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The monitor device receives real-time data from the sensor assembly and provides immediate feedback to the user through visual or audible alerts when leakage is detected. This feedback mechanism enables users to respond promptly to leakage conditions, preventing skin damage while reducing the need for continuous manual monitoring

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs self-monitoring through the integrated sensor assembly that automatically detects moisture and leakage conditions. The monitor device autonomously processes sensor data and generates alerts without requiring user intervention, allowing the appliance to monitor itself and notify users only when action is needed

Inventive Principle:

Principle #25Self-service

AI summary

An ostomy system includes a base plate, an electrode assembly configured to sense ostomy data, and a monitor device attachable to and detachable from the electrode assembly. The base plate has a coupling part formed as a socket and the monitor device has a coupling part provided as a monitor protrusion. When the monitor protrusion is inserted into the socket, a monitor terminal of the monitor protrusion electrically connects with a terminal of the socket to allow the monitor device to receive and transmit the ostomy data to a user.
