Solution Overview

Problem

Existing medical fluid receiving devices face challenges in managing fluid flow, leading to turbulence, gas inclusions, and foam formation, which can result in inefficient fluid exchange and inaccurate measurements during filling and emptying processes.

Innovation Solution

A receiving device equipped with a fluid surge deflection element, such as a flow-around body, that redirects and divides the incoming fluid surge into separate partial flows, minimizing turbulence and gas inclusion, and optimizing fluid exchange by arranging the flow-around body symmetrically within the inflow area to ensure complete fluid entry and exit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional receiving devices are used for fluid intake, then fluid can be received, but turbulence and gas inclusions occur leading to inaccurate measurements

Engineering Contradiction:
Improvefluid measurement accuracyVSAvoidturbulence and gas inclusions
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The incoming fluid surge is divided into multiple partial flows by the flow-around body, which segments the single large flow into several smaller flows that can be managed more effectively, reducing turbulence and gas inclusion formation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow-around body acts as an intermediary element between the incoming fluid and the receiving device interior, modifying the fluid flow characteristics before it enters the main chamber to prevent harmful flow patterns

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If rapid fluid filling is performed, then productivity increases, but foam formation and turbulence increase reducing measurement precision

Engineering Contradiction:
Improvefluid filling speedVSAvoidfluid measurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

By segmenting the high-speed fluid surge into multiple partial flows using the flow-around body, the system can maintain high filling speeds while preventing the formation of foam and turbulence that would compromise measurement accuracy

Inventive Principle:
Principle #1Segmentation

3Device complexity

If fluid surge is directly introduced into the receiving device, then device complexity is minimized, but foreign surface contact increases reducing hemocompatibility

Engineering Contradiction:
Improvereceiving device structureVSAvoidforeign surface contact
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The flow-around body extends into the fluid path from the side walls, utilizing the lateral dimension to create flow division without adding significant vertical height or complex internal structures to the receiving device

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