Solution Overview

Problem

Current incubator systems for premature infants before implantation lack effective thermoregulation and ventilation, leading to inadequate care, and practitioners rely on creating multiple embryos due to poor incubation techniques, resulting in high mortality rates and unethical practices like genifection.

Innovation Solution

A side-vented microcradle with a clear bottom and open top, utilizing microfabricated cradle technology for precise thermoregulation and gentle fluidic ventilation, integrated with a fluidic circuit assembly and temperature bath for maintaining ambient temperature, ensuring proper care and reducing the need for multiple embryo creation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional incubator systems are used for premature infants before implantation, then the infrastructure for infant care is available, but thermoregulation and ventilation are inadequate leading to high mortality rates

Engineering Contradiction:

Improvemortality rateVSAvoidinfant survival

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The patent modifies the physical parameters of the incubator environment by introducing a fluidic medium that enables precise thermoregulation through controlled temperature and flow parameters. The system changes the state of the incubation environment from stagnant air to a dynamic fluid medium that can be precisely controlled for temperature, pressure, and flow rate, directly addressing the inadequate thermoregulation and ventilation that caused high mortality rates

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies hydraulic principles by introducing a fluidic ventilation system that circulates liquid medium through the incubator chamber. This fluidic system provides gentle ventilation and thermoregulation through controlled fluid flow, replacing the inadequate air-based traditional incubator systems with a hydraulic medium that enables precise environmental control for improved infant survival

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Productivity

If multiple embryos are created to compensate for poor incubation techniques, then the number of embryos increases, but this leads to unethical practices like genifection and high mortality rates

Engineering Contradiction:

Improveembryo creation quantityVSAvoidunethical practices and mortality

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements feedback control mechanisms that monitor the incubation environment parameters (temperature, fluid flow, ventilation) and automatically adjust them to maintain optimal conditions. This closed-loop feedback system ensures consistent high-quality incubation, eliminating the need to create multiple embryos as a compensatory measure and preventing the unethical practices associated with mass embryo creation

Inventive Principle:

Principle #23Feedback

3Reliability

If a vented microcradle with fluidic ventilation is implemented, then gentle fluidic ventilation and thermoregulation are achieved, but the device complexity increases

Engineering Contradiction:

Improvethermoregulation and ventilation effectivenessVSAvoidmicrocradle structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the incubator system into segmented functional modules: the microcradle structure, fluidic circulation system, temperature control modules, and ventilation channels. Each segment performs a specific function (thermoregulation, ventilation, structural support), allowing the complex system to be managed through modular components that can be independently optimized and maintained
