Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image processing is used to visualize blood vessels, then blood vessel positions can be displayed, but blood vessels cannot be specified according to particular purposes such as needle puncture suitability
Solution Approach 1:
The patent applies parameter changes by introducing multiple evaluation parameters (straightness, direction, length, thickness, distance from puncture point) to transform the blood vessel specification process from simple visualization to purpose-specific selection. This allows the system to evaluate and rank blood vessels based on their suitability for particular procedures like needle puncture.
Solution Approach 2:
The patent adds a new dimension of evaluation by introducing point rating scores based on multiple parameters. This transforms the problem from two-dimensional spatial visualization to a three-dimensional evaluation space that includes suitability scoring, enabling purpose-specific blood vessel specification beyond mere position display.
2Measurement precision
If multiple parameters are evaluated to specify blood vessels for particular purposes, then specification accuracy improves, but system complexity increases
Solution Approach 1:
The patent segments the evaluation process into distinct components: image processing to extract blood vessel information, separate evaluation modules for each parameter (straightness, direction, length, thickness, distance), and a scoring integration mechanism. This modular segmentation manages complexity by breaking down the multifaceted evaluation into manageable, independent assessment stages.
Solution Approach 2:
The patent manages complexity through parameter standardization and normalization, converting diverse blood vessel characteristics into a unified point rating system. This allows multiple parameters to be evaluated and compared on a common scale, simplifying the integration of multiple evaluation dimensions into a single specification decision.
