Solution Overview

Problem

Chocolate is difficult to maintain in a fresh, homogenous state for extended periods due to oxidation and separation issues when in a molten form, leading to the need for tempering and cold chain distribution, which increases costs and complexity.

Innovation Solution

A content dispensing apparatus that includes a housing with a deformable pouch containing chocolate, a heater, and an agitator, allowing for warming and agitation to maintain a homogeneous, lower viscosity state, and a fluidic conduit with a valve for controlled dispensing, which prevents oxidation and separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If chocolate is maintained in a molten state for extended periods, then it remains ready for dispensing, but it undergoes oxidation and separation leading to degradation

Engineering Contradiction:
Improveduration chocolate remains ready for dispensingVSAvoidoxidation and separation
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent applies an inert atmosphere by filling the dispensing container with nitrogen gas to displace oxygen, preventing oxidation of the molten chocolate during extended storage. The nitrogen atmosphere maintains the chocolate in a fresh state without the harmful oxidative effects that would normally occur over time.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The patent extracts the harmful oxygen from the environment by replacing it with inert nitrogen gas. This removal of the oxidizing agent prevents both oxidation and separation issues, allowing the chocolate to remain stable in molten form for extended periods without degradation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If chocolate is tempered and stored in solid form, then oxidation is prevented, but it requires cold chain distribution and loses flavor immediacy

Engineering Contradiction:
Improveoxidation preventionVSAvoidcold chain distribution requirement
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent uses an inert nitrogen atmosphere in the dispensing container to prevent oxidation of molten chocolate, eliminating the need for tempering and cold chain distribution. This allows the chocolate to be stored and dispensed in a convenient molten state without the complexity of temperature-controlled logistics.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Stability of the object's composition

If chocolate is continuously mixed and heated to maintain homogeneity, then separation is prevented, but oxidation and flavor loss increase

Engineering Contradiction:
Improvehomogeneity of chocolateVSAvoidoxidation and flavor loss
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the open air environment with an inert nitrogen atmosphere in the dispensing container, preventing oxidation while maintaining homogeneity. This eliminates the need for continuous mixing and heating to prevent separation, as the inert atmosphere stabilizes the chocolate composition without requiring active intervention.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

4Shape

If rapid cooling is used to temper chocolate, then solid bar formation is achieved, but large expensive cooling tunnels are required

Engineering Contradiction:
Improvesolid bar formationVSAvoidcooling tunnel size and cost
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent inverts the traditional approach by maintaining chocolate in a molten state for dispensing rather than cooling it to form solid bars. This eliminates the need for expensive rapid cooling tunnels while still achieving the desired product form through controlled dispensing and setting in molds.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Systems and methods for preparing and dispensing food contents, typically molten chocolate. In one aspect, a system includes a deformable fluid-tight container shell defining an internal volume and separating the internal volume from an external environment; a semi-solid content contained within the internal volume; a valve stem operationally connected to and disposed at least partially through the deformable container shell; and a valve disposed in the external environment and operationally connected to the valve stem. The semi-solid content may be a hydrophobic matrix with at least partially emulsified hydrophilic components suspended therein; the container shell may be substantially fluid-tight; the valve may be self-cleaning; the internal volume may be in fluidic communication with the external environment where the valve is open but not when the valve is closed.
