Solution Overview

Problem

Conventional chocolate confections melt quickly at temperatures near 37°C, posing storage and handling challenges, especially in regions with high environmental temperatures, and require additional processing steps that increase costs and time.

Innovation Solution

A premix comprising unmilled dextrose monohydrate with an average particle size of greater than 50 microns and glycerin is used to create a heat-resistant chocolate confection, eliminating the need for milling and providing enhanced heat resistance without compromising texture or taste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cocoa butter is used to achieve quick and complete melting at 37°C, then the organoleptic eating experience is improved, but the heat resistance during storage and handling deteriorates

Engineering Contradiction:
Improvemelting profileVSAvoidheat resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses composite materials by combining cocoa butter with alternative fats having different melting points and properties. This creates a fat blend that maintains the desirable melting profile of cocoa butter while adding heat resistance from the alternative fats, resolving the contradiction between quick melting and heat stability during storage

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes the physical and chemical parameters of the fat component by incorporating fats with higher melting points and different crystalline structures. This modifies the overall melting behavior and thermal stability parameters of the confection, allowing it to resist heat during storage while still melting appropriately at consumption temperature

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If sweeteners and milk or cocoa solids are milled to small particle sizes to avoid gritty texture, then the mouthfeel is improved, but the manufacturing cost and process complexity increase

Engineering Contradiction:
ImprovemouthfeelVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent inverts the conventional approach by using large particle size sweeteners and solids instead of fine milled particles. This reversal challenges the traditional assumption that fine particles are necessary for good mouthfeel, and instead leverages the natural properties of coarser particles to achieve both acceptable texture and manufacturing simplicity

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

Solution Approach 2:

The patent applies local quality by allowing different particle sizes in different components of the confection. Rather than uniformly milling all solid components to fine particles, it permits larger particle sizes in sweeteners and milk or cocoa solids where they do not adversely affect mouthfeel, thereby reducing manufacturing complexity while maintaining overall product quality

Inventive Principle:
Principle #3Local quality

3Reliability

If refrigerated storage is used to maintain heat resistance, then the shape stability is improved, but the storage cost and infrastructure requirements increase

Engineering Contradiction:
Improveshape stabilityVSAvoidstorage cost
Core Design Contradiction:
ReliabilityVSUse of energy by stationary object

Solution Approach 1:

The patent makes the confection self-service regarding heat resistance by incorporating fats with high melting points and exceptional thermal stability directly into the formulation. This allows the product to maintain its shape and structural integrity at ambient temperatures without requiring external refrigeration infrastructure, eliminating the need for energy-intensive cold storage

Inventive Principle:
Principle #25Self-service
