Multi-View Vessel Measurement Tape for Length and Lumen Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices and methods for measuring body parts, such as vessels and lesions, are limited to single-distance measurements and do not accommodate anterior, posterior, or oblique views, which are necessary for certain surgical procedures.
Innovation Solution
A measuring device comprising measurement tapes with measurement marks and circular indicators that allow for precise placement and accurate measurement of distances, lengths, and diameters of vessels, including multiple views, using parallel tapes, straps, and varying circular indicator sizes for different diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single measurement tape is used, then the device complexity is low, but the measurement capability is limited to single distance only
Solution Approach 1:
The measurement device is divided into multiple measurement tapes (e.g., first measurement tape, second measurement tape) that can be positioned independently. Each tape contains measurement marks and circular indicators, allowing simultaneous measurement of multiple parameters (distance, length, diameter) from different views (anterior, posterior, oblique) without requiring a single complex tape
2Adaptability or versatility
If multiple measurement tapes are added to enable multiple views, then the measurement capability improves, but the device complexity increases
Solution Approach 1:
Each measurement tape is designed as a universal measuring tool that can measure multiple parameters (distance between reference points, length of vessels, diameter of lumens) and can be used from multiple viewing angles. The tapes contain both linear measurement marks and circular diameter indicators, making each tape multi-functional and reducing the need for separate specialized tools
3Measurement precision
If measurement marks are spaced far apart (e.g., 5 cm), then the measurement range is larger, but the measurement precision decreases
Solution Approach 1:
The measurement tape uses segmented marking intervals with different precision levels. Major measurement marks are spaced at larger intervals (e.g., 5 cm) for quick reference and orientation, while sub-markers are positioned at smaller intervals (e.g., 1 cm) between the major marks to provide precise measurements when needed, combining both wide coverage and high precision
