Solution Overview

Problem

Conventional ultrasonic imaging apparatuses for capturing wide cross-sections of the human body are complex, large in scale, and require significant time and labor to attach and maneuver, making it difficult to maintain the probe at a suitable angle without deforming the body tissues, especially when imaging curved surfaces.

Innovation Solution

An ultrasonic imaging apparatus with a probe adapter that maintains the probe at a constant angle, allowing for a larger contact area and preventing strong pressure on the body surface, enabling accurate imaging of internal tissues by switching between linear and sector scan modes and using an angle sensor for precise image composition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a conventional ultrasonic imaging apparatus is used to capture wide cross-sections of the human body, then the imaging coverage is improved, but the device complexity and time required for imaging increase significantly

Engineering Contradiction:
Improveimaging coverageVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The imaging process is segmented into multiple linear scan lines that are sequentially acquired and then synthesized to form a complete sector scan image. This allows the use of a simple linear probe instead of a complex sector scan probe, reducing device complexity while maintaining wide imaging coverage

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-dimension linear scan to a two-dimension sector scan by moving the probe along an arc path. This dimensional change enables wide-area imaging coverage while using simple linear scan hardware, resolving the contradiction between coverage and complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the probe is moved along the body surface to image wide areas, then the imaging range is improved, but the probe angle becomes difficult to maintain without deforming body tissues

Engineering Contradiction:
Improveimaging rangeVSAvoidease of operation
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The probe is moved along a curved arc path rather than a straight line, with the curvature radius matching the body surface geometry. This curved motion path maintains a constant optimal probe angle relative to the skin surface throughout the scan, eliminating the need for complex angle adjustments and preventing tissue deformation while achieving wide imaging coverage

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Area of stationary object

If the probe is pressed strongly against the body surface to maintain contact, then the contact area is improved, but the body tissues are deformed

Engineering Contradiction:
Improvecontact areaVSAvoidtissue deformation
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

By moving the probe along a curved arc path that matches the body surface geometry, the probe maintains a constant optimal contact angle throughout the scan. This geometric approach ensures adequate ultrasonic coupling and contact area without requiring excessive pressing force, thereby preventing tissue deformation while maintaining imaging quality

Inventive Principle:
Principle #14Spheroidality (Curvature)
