Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If arrows are used to indicate current vectors in an organ model, then the current flow information is visualized, but the surgeon's view is obstructed and lesion detection is hindered
Solution Approach 1:
The patent applies color mapping to represent current vector magnitude and direction in the organ model. Different colors indicate different current intensities and flow directions, allowing comprehensive visualization without using arrows that would obstruct the surgeon's view. This color-based encoding maintains information density while improving visual clarity.
2Loss of information
If arrows are used to indicate current vectors, then current direction is shown, but the detection time for lesions increases
Solution Approach 1:
The patent uses color encoding to represent current direction and magnitude simultaneously. By mapping directional information to color hue or orientation within the color scheme, the system conveys vector information without requiring discrete arrow indicators, thereby reducing visual clutter and accelerating lesion detection.
3Ease of operation
If color attributes are used to express current changes, then the visualization becomes more intuitive, but the device complexity increases
Solution Approach 1:
The patent transforms current vector data into visual parameters by mapping current magnitude and direction to color attributes such as hue, saturation, and brightness. This parameter transformation approach enables intuitive visualization through standard color perception while utilizing established image processing techniques to manage computational complexity.

Data Source
AI summary
A system provides for the visualization of an organ's electrical activity. Circuitry acquires image information to generate an anatomical organ model and also acquires biomagnetic field information from the organ. An electrocardiogramrent image is generated from the biomagnetic field information. This current image expresses over-time changes in the organ's electrical current by using a change in a color attribute to visually represent the temporal trend of the current rising or falling at various positions. A final composite image is generated by superposing the current image onto the anatomical organ model.
