Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If fluorescence imaging is used to visualize cauterization state, then visualization of treatment status is improved, but ability to detect discharge status of resected pieces is insufficient

Engineering Contradiction:

Improvevisualization precision of cauterization stateVSAvoiddetection difficulty of resected piece discharge status

Core Design Contradiction:

Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary imaging of the target region before treatment to establish a baseline fluorescence image. This allows subsequent comparison with post-treatment images to detect changes in fluorescence intensity that indicate resected piece discharge status, thereby solving the detection difficulty problem.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously acquires fluorescence images during and after treatment, processes them to detect changes in fluorescence intensity, and provides real-time feedback about the discharge status of resected pieces. This feedback mechanism enables operators to monitor treatment progress and confirm successful removal.

Inventive Principle:

Principle #23Feedback

2Speed

If single-timepoint imaging is used, then imaging speed is maintained, but ability to detect changes in tissue state is insufficient

Engineering Contradiction:

Improveimaging speedVSAvoiddetection precision of tissue state changes

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The system acquires a baseline fluorescence image before treatment begins, establishing a reference state. This preliminary imaging enables subsequent detection of temporal changes in tissue state during and after treatment without significantly impacting overall imaging speed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs imaging at multiple timepoints (before treatment, during treatment, and after treatment) to detect temporal changes in fluorescence intensity. This periodic imaging approach enables detection of tissue state changes while maintaining acceptable imaging speed through efficient acquisition and processing.

Inventive Principle:

Principle #19Periodic action

3Reliability

If fluorescence imaging is applied to visualize thermal treatment effects, then treatment monitoring is improved, but visualization of post-treatment discharge status is insufficient

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system captures a baseline fluorescence image before treatment to establish the initial tissue state. This preliminary image serves as a reference for detecting subsequent changes, including the discharge of resected pieces, thereby preventing information loss about post-treatment status.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system processes fluorescence images acquired at multiple timepoints to detect changes in fluorescence intensity that correspond to resected piece discharge. This feedback mechanism provides continuous information about treatment progress and post-treatment discharge status, eliminating information loss.
