Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional ultrasonic diagnostic apparatus methods are used for puncture guidance, then basic ultrasonic imaging is provided, but user stress and operational difficulty increase due to insufficient support

Engineering Contradiction:

Improveease of puncture operationVSAvoidpuncture accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A general-purpose terminal apparatus serves as an intermediary between the operator and the ultrasonic probe apparatus. This terminal acquires position and angle information, communicates with the probe apparatus via wireless communication, and displays integrated puncture guidance information including ultrasonic images and guide lines, thereby facilitating easier and more accurate puncture operations

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The general-purpose terminal apparatus performs multiple functions: it displays ultrasonic images received from the probe apparatus, shows puncture guide lines based on acquired position and angle information, provides real-time feedback during puncture procedures, and integrates various information sources into a unified display interface

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If detailed puncture guidance information is provided through additional apparatuses, then puncture accuracy improves, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system utilizes the general-purpose terminal apparatus's existing display and processing capabilities to provide puncture guidance, rather than requiring a completely separate dedicated guidance device. The terminal serves itself by integrating multiple functions into a single platform

Inventive Principle:

Principle #25Self-service

AI summary

A processor of a general-purpose terminal acquires position information indicating whether a biological body is punctured from a first side of an ultrasonic probe apparatus or a second side opposite to the first side and angle information indicating a puncture angle, where these items of information are entered on a touch panel of a display, transmits these items of information to the probe apparatus via a wireless communication circuit, acquires, via the communication circuit, image information generated and transmitted by the probe apparatus based on reflected waves obtained by transmitting ultrasonic waves into the biological body from the probe apparatus at a first angle based on the above information, superimposes a puncture guide indicating a puncture path based on the above information on an ultrasonic image of the biological body or a puncture needle based on the image information, and displays a result of the superimposing on the display.
