Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If coil adaptation is performed manually inside the MRI bore, then operator control is maintained, but productivity is reduced and operator workload increases

Engineering Contradiction:

Solution Approach 1:

The coil adaptation system performs self-adjustment using automated actuators that modify coil position and shape based on patient geometry data and imaging feedback, eliminating the need for manual operator intervention during the adaptation process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-adapts the coil to the patient's body geometry before imaging begins by calculating optimal coil configuration from patient shape data and automatically positioning the coil, so that the coil is ready for imaging without requiring manual adjustment inside the bore

Inventive Principle:
Principle #10Preliminary action

2Productivity

If coil pre-forming is performed outside the MRI bore, then productivity increases and patient training time is reduced, but additional positioning steps are required

Engineering Contradiction:
ImproveMRI system productivityVSAvoidadaptation process complexity
Core Design Contradiction:
