Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic measurement systems for biological tissue elasticity are limited in measuring lateral elasticity due to their inability to generate shear waves in lateral directions and require position shifts for sequential longitudinal section measurements, leading to inaccuracies.
Innovation Solution
An ultrasonic device with a base assembly, vibrator, and ultrasonic probe that includes annular and installation bases, allowing for rotation between testing positions to emit fan-shaped arcing beams parallel to abutment protrusions, enabling simultaneous measurement of longitudinal and lateral tissue elasticity through mechanical waves and ultrasonic signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the combined vibrator and ultrasonic probe is rotated to change orientation of the fan-shaped arcing beam for measuring different longitudinal sections, then the measurement coverage is improved, but the position of the combined vibrator and ultrasonic probe shifts relative to the site, causing shift between center parts of the two longitudinal sections
Solution Approach 1:
The device is divided into separate functional components: the ultrasonic probe for imaging and the vibrator for mechanical wave generation. The vibrator is mounted on a rotatable installation base that can be independently positioned, allowing the ultrasonic probe to remain stationary while the vibrator rotates to different testing positions. This segmentation eliminates position shift between the probe and the measurement site.
Solution Approach 2:
The installation base is designed to be rotatable about the Z-axis between at least two testing positions, allowing dynamic repositioning of the vibrator while keeping the ultrasonic probe stationary. This dynamic adjustment enables measurement of different longitudinal sections without moving the probe, maintaining measurement precision.
2Adaptability or versatility
If conventional ultrasonic measurement system is used to measure longitudinal elasticity, then the measurement function is complete for longitudinal direction, but the system cannot measure elasticity of the biological tissue in lateral directions due to inability to generate shear waves that travel in lateral directions
Solution Approach 1:
The vibrator generates mechanical waves with frequency in a range of from 100 Hz to 400 Hz that travel through the biological tissue. By controlling the vibration frequency and direction, the system can generate shear waves that propagate in both longitudinal and lateral directions, enabling measurement of elasticity in multiple directions.
Solution Approach 2:
The system changes the frequency parameter of the mechanical waves from conventional ultrasonic frequencies to lower frequencies (100-400 Hz), which enables the generation of shear waves capable of traveling in lateral directions. This parameter change allows the system to measure both longitudinal and lateral elasticity.
3Productivity
If the vibrator is driven to apply mechanical wave to the biological tissue while the ultrasonic probe performs ultrasonic sensing, then the elasticity data can be obtained through analysis of ultrasound images, but the system complexity increases due to coordination requirements between vibrator and probe
Solution Approach 1:
The ultrasonic probe and vibrator are merged into a single integrated assembly where the vibrator is mounted on the installation base that also holds the ultrasonic probe. This merging allows simultaneous operation of both components with coordinated control, improving measurement efficiency while managing complexity through integration.
Solution Approach 2:
The installation base serves as a common mounting structure that automatically positions both the ultrasonic probe and the vibrator at the correct locations and orientations. The rotatable design of the installation base provides self-adjusting capability, reducing the need for complex external coordination mechanisms.
