Solution Overview

Problem

Conventional ultrasonic diagnostic apparatuses face difficulties in allowing users to easily select and obtain desired images due to the manual adjustment required for rotating the ultrasound probe's array angle, which is inconvenient and time-consuming.

Innovation Solution

An ultrasonic diagnostic apparatus equipped with a controller that captures and displays multiple images based on the rotation angle of the array, allowing users to select and display the desired image, with options for real-time or sequential display, and the ability to distinguish and enlarge the selected image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of array angle is used to acquire desired ultrasound images, then the user can obtain images at specific angles, but the operation becomes inconvenient and time-consuming

Engineering Contradiction:
Improveease of image selectionVSAvoidtime for manual adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically capturing multiple ultrasound images at different array rotation angles in advance. The controller rotates the array to predetermined angles and stores the captured images, so when the user wants to view images at specific angles, they are already available for immediate selection and display without requiring manual rotation adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates copies of ultrasound images at different rotation angles and stores them in memory. Instead of requiring the user to manually rotate the probe to obtain each desired angle, the controller has already captured and stored multiple copies of images at various angles, allowing the user to simply select from the available copies for display.

Inventive Principle:
Principle #26Copying

2Ease of operation

If multiple images are captured and displayed for user selection, then the user can easily find desired images, but the device complexity increases

Engineering Contradiction:
Improveease of image selectionVSAvoidcomplexity of control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The controller performs multiple functions: it automatically rotates the array to predetermined angles, captures ultrasound images at each angle, stores the images in memory, and displays them for user selection. By consolidating these functions into a single controller, the system achieves multi-functionality without proportionally increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system provides self-service by automatically performing the image capture and display functions without requiring manual operation for each angle adjustment. The controller autonomously rotates the array, captures images at multiple angles, and presents them for selection, reducing the operational burden on the user while maintaining manageable system complexity through automation.

Inventive Principle:
Principle #25Self-service
