Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If bodily fluid is directed tangentially into the cartridge body at high speed, then the adsorption process can proceed quickly, but turbulence and chaotic flow increase causing platelet activation and fibrinogen deposition

Engineering Contradiction:
Improveadsorption speedVSAvoidplatelet activation and fibrinogen deposition
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The conical end segment is positioned before the adsorptive material to preliminarily decelerate and condition the bodily fluid flow before it contacts the adsorptive material. This preliminary action reduces flow velocity and turbulence intensity, preventing platelet activation and fibrinogen deposition while maintaining efficient adsorption throughput

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The conical geometry of the end segment changes the flow parameters by progressively reducing flow velocity and transforming chaotic turbulent flow into more laminar flow patterns. This parameter change optimizes the flow conditions for adsorption while minimizing harmful effects on blood components

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a straight inlet directly into the cartridge body is used, then the device complexity is reduced, but chaotic flow patterns and turbulence increase

Engineering Contradiction:
Improveinlet structure simplicityVSAvoidflow pattern stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The conical end segment introduces a curved, tapered geometry that guides flow smoothly into the cartridge body. This curved transition replaces abrupt straight-line flow paths, reducing flow separation and turbulence while maintaining relatively simple device construction

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

Systems and methods for the treatment of a bodily fluid, for example, using a cartridge that may include a cartridge body configured to retain an adsorptive material and an end segment configured to cover a first end of the cartridge body. The end segment may include a circular face comprising an outwardly truncated conical shape and defining an internal conical space, a cylindrical wall joined to a periphery of the circular face, and an inlet configured to provide fluid connection to a source of the bodily fluid. The inlet may be disposed tangential to the circular face at the cylindrical wall so as to direct bodily fluid entering the cartridge into the internal conical space tangentially so as to decelerate the bodily fluid within the internal conical space prior to contact with the adsorptive material disposed within the cartridge body.
