Solution Overview

Problem

Conventional three-dimensional ultrasonic probes can only capture images in one direction due to restricted movement, limiting their ability to obtain images in multiple directions without changing the probing direction.

Innovation Solution

A three-dimensional probe apparatus featuring a drive unit, power transmission unit, and location detector, allowing the transducer to move in multiple directions via a wire member guided by first and second guide members, enabling the probe to operate in various directions without altering its initial direction, and incorporating a location detection system to define the transducer's position for precise control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the transducer moves only along a restricted locus in the probing direction, then the device structure is simple, but the probe can obtain only an image in one direction and cannot capture images in multiple directions

Engineering Contradiction:
Improveprobing direction flexibilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention introduces a new degree of freedom by enabling the transducer to move not only along the probing direction (first direction) but also in a direction perpendicular to it (second direction). This dimensional expansion allows the probe to capture images in multiple directions without changing the probing direction itself, resolving the contradiction between versatility and structural simplicity.

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

Solution Approach 2:

The invention employs dynamic control of the transducer position through a location detector that identifies specific locations along the first direction. The transducer can be selectively positioned at different locations and moved in the second direction, providing dynamic adaptability in probing directions while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the transducer is moved to multiple locations and operated in different directions, then images in multiple directions can be obtained, but the apparatus size increases

Engineering Contradiction:
Improveprobing direction capabilityVSAvoidapparatus size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The invention segments the probing function by dividing it into two independent movement components: movement in the first direction (controlled by location detection) and movement in the second direction (perpendicular movement). This segmentation allows the transducer to achieve multi-directional imaging capability while keeping each movement mechanism compact, thus avoiding a significant increase in overall apparatus size.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is a three-dimensional probe apparatus. The probe apparatus includes a drive unit (120) generating power in a forward or rearward direction, a power transmission unit (130) transmitting the power in association with the drive unit (120), a transducer (140) receiving the power from the power transmission unit (130) to move towards a plurality of locations for operation, and a location detector (150) detecting a moving location of the transducer (140) to allow the transducer (140) to move towards the plurality of locations for operation. The transducer (140) may move towards a plurality of locations for operation and the location detector (150) may detect a moving location of the transducer (140) to define the location of the transducer (140) so as to differently control the operation of the transducer (140) in accordance with the moving location of the transducer (140), so that the probe apparatus can perform the probing operation in a plurality of directions at one position without changing the probing direction.
