Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If manual disposal and cleaning procedures are used, then the cleaning process can be completed, but the user or caregiver is exposed to contaminants from the collected fluid

Engineering Contradiction:

Improveexposure to contaminantsVSAvoidmanual cleaning procedure

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system enables self-service cleaning where the collected fluid is automatically expelled and the device is flushed using its own stored fluid resources, eliminating the need for manual intervention and caregiver exposure to contaminants

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A pump system acts as an intermediary mechanism between the collection container and disposal system, automatically transferring and expelling collected fluid without requiring direct manual handling by caregivers

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If manual cleaning procedures are used, then the device can be cleaned, but extensive cleaning procedures are required which consume time and resources

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidcleaning time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary flushing action by storing cleaning fluid in advance within the device, enabling rapid cleanup without requiring extensive post-collection cleaning procedures

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous functionality by automatically expelling collected fluid and flushing the device in sequence, eliminating downtime and ensuring the device is ready for next use without manual intervention

Inventive Principle:

Principle #20Continuity of useful action
