Solution Overview

Problem

The challenge lies in simultaneously achieving miniaturization of the main body and enlargement of the display device in transportable ultrasonic diagnostic apparatuses, as the small-sized main body struggles to stably carry a large-sized display device, requiring either a larger main body or a smaller display device, which compromises mobility and space-effectiveness.

Innovation Solution

A caster assembly featuring crossed support bars with a joint shaft and thrust bearings, allowing the support bars to pivot and interlock, enabling stable support of both small-sized and large-sized ultrasonic diagnostic apparatuses by maintaining consistent caster spacing, thus enhancing mobility and space-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the main body is miniaturized to improve mobility and space-effectiveness, then the main body size is reduced, but the main body cannot stably carry a large-sized display device

Engineering Contradiction:
Improvemain body sizeVSAvoidstability of display device support
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The support structure is segmented into multiple support bars (first support bar and second support bar) that can be independently positioned and adjusted. This segmentation allows the display device to be distributed across multiple support points, enhancing stability even when the main body is miniaturized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support bars are configured to extend in different directions (first support bar in first direction, second support bar in second direction perpendicular to the first), creating a three-dimensional support structure. This dimensional arrangement provides stable support for the display device without requiring a larger main body volume.

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

2Stability of the object's composition

If the main body size is increased to stably carry a large-sized display device, then the stability is improved, but mobility and space-effectiveness are compromised

Engineering Contradiction:
Improvestability of display device supportVSAvoidmain body size
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The support bars are designed to be movable and adjustable rather than fixed. The first support bar can be moved along the first direction and the second support bar along the second direction, allowing dynamic adaptation to different display device sizes and configurations without increasing the main body volume.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support structure serves multiple functions: it supports the display device, allows adjustment for different configurations, and maintains stability without requiring a larger main body. The universal design accommodates various display device sizes through the adjustable support bars.

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

3Volume of moving object

If the display device size is reduced to match the miniaturized main body, then space-effectiveness is improved, but the display quality and information provision are compromised

Engineering Contradiction:
Improvedisplay device sizeVSAvoiddisplay quality and information provision
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The support structure segments the load-bearing function across multiple support bars, allowing a larger display device to be supported by distributing its weight across multiple points. This enables the display device to maintain a larger size for better quality while the main body remains miniaturized.

Inventive Principle:
Principle #1Segmentation

4Device complexity

If fixed-position casters are used, then the structure is simple, but the apparatus cannot be flexibly positioned or oriented during transport and installation

Engineering Contradiction:
Improvecaster structure complexityVSAvoidpositioning flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The caster assembly incorporates movable support bars that can be adjusted along their respective directions. This dynamic capability allows the apparatus to be flexibly positioned and oriented during transport and installation, while the caster structure itself remains relatively simple in design.

Inventive Principle:
Principle #15Dynamics
