Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If periodic calibration is performed in the patient space, then the imaging system can be maintained, but workflow is interrupted and efficiency is reduced

Engineering Contradiction:
Improveimaging system operationVSAvoidworkflow efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent divides the imaging system into a fixed imaging room and a mobile imaging system that can be moved to a separate calibration room. This segmentation allows calibration to occur in a dedicated space without disrupting patient care in the imaging room, resolving the contradiction between maintaining system reliability and preserving workflow efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The calibration function is extracted from the patient space by moving the imaging system to a dedicated calibration room. This extraction allows calibration activities to be performed separately from patient care activities, eliminating workflow interruptions while maintaining imaging system reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a mobile imaging system is used, then calibration can be performed outside patient space, but the system requires automated calibration processes

Engineering Contradiction:
Improvecalibration location flexibilityVSAvoidcalibration process automation
Core Design Contradiction:
Adaptability or versatilityVSExtent of automation

Solution Approach 1:

The mobile imaging system is equipped with automated calibration capabilities that allow it to self-calibrate using a calibration source in the calibration room.
