Solution Overview

Problem

Existing devices for warming breast milk in bottles often denature proteins and break down essential nutrients due to aggressive shaking or heating, which can render the milk ineffective for infant nutrition.

Innovation Solution

A device that simultaneously rotates and warms the breast milk within a container using a heating mechanism and motor, ensuring gentle mixing and preservation of nutrients by using a basket with perforations and a steam heating system, allowing for uniform heating without physical agitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If aggressive shaking is used to mix fat back into breast milk, then mixing efficiency is improved, but protein denaturation and nutrient breakdown occur

Engineering Contradiction:
Improvemixing efficiencyVSAvoidprotein denaturation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the traditional mechanical shaking method with a thermal field-based approach. A heating element gently warms the breast milk container while it rotates on a turntable, allowing fat to naturally mix back into the milk through thermal convection and gentle rotation, avoiding the mechanical violence that causes protein denaturation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the mixing mechanism from mechanical agitation to thermal convection. By controlling the temperature parameter (heating to body temperature around 37°C) and rotation speed parameter (gentle rotation), the system achieves effective mixing without the harmful mechanical forces that cause nutrient breakdown.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If rapid heating is applied to warm breast milk, then warming speed is improved, but nutrient degradation increases

Engineering Contradiction:
Improvewarming timeVSAvoidnutrient degradation
Core Design Contradiction:
Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The patent replaces direct contact heating with indirect thermal field heating. The heating element warms the air and water vapor in the chamber, which then gently heats the breast milk container through thermal radiation and convection, providing uniform and controlled heating that prevents nutrient degradation while maintaining reasonable warming speed.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces water vapor as an intermediary heating medium. Water is heated to produce steam that fills the chamber, and this steam gently heats the breast milk container through condensation and convection, providing a buffer that prevents direct high-temperature contact and ensures gentle, uniform heating.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If high-speed rotation is used to mix contents, then mixing speed is improved, but gentle mixing requirement is violated

Engineering Contradiction:
Improverotation speedVSAvoidprotein denaturation
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the rotation speed parameter to a low range that provides gentle mixing. The turntable rotates slowly enough to allow natural convection currents to form as the milk heats, creating effective mixing without generating centrifugal forces strong enough to denature proteins or create harmful turbulence.

Inventive Principle:
Principle #35Parameter changes

AI summary

A warming device that heats and agitates a container. The warming device has a housing having an enclosed chamber and a concentric warming chamber adapted to receive a first fluid. A concentric basket is provided that is adapted to fit within the warming chamber. The concentric basket secures the container partially submerged within the first fluid. At least one heating element is provided to heat the first fluid in the warming chamber to warm an exterior surface of the container. A motor is provided to agitate and warm a second fluid in the container by rotating the concentric basket at a predetermined rate. A control panel provides various signal instructions to the heating element and the motor.
