Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cotton candy's fragile texture and hygroscopic nature make it difficult to coat with chocolate without ruining its structure or causing the chocolate to melt, resulting in an unappealing mess when attempting to create chocolate truffles with a cotton candy filling.

Innovation Solution

Forming cotton candy into a desired shape, allowing it to age and develop a thin crust of hydrated sugar, which acts as a barrier against chocolate infiltration and melting, enabling reliable coating with chocolate or encasing within pre-formed shells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If freshly-made cotton candy is coated with chocolate, then chocolate truffles can be created, but the chocolate infiltrates the strands and melts them, ruining the texture

Engineering Contradiction:

Improvecoating processVSAvoidcotton candy texture

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The cotton candy is aged in ambient or semi-humid conditions before coating to allow a thin crust of hydrated sugar to form naturally. This preliminary action creates a protective barrier that prevents chocolate infiltration during the subsequent coating process, resolving the contradiction between ease of manufacture and texture stability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A thin crust of hydrated sugar acts as an intermediary layer between the cotton candy strands and the chocolate coating. This intermediary prevents direct contact between the chocolate and the delicate cotton candy strands, eliminating infiltration and melting issues while allowing the coating process to proceed smoothly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If cotton candy is aged to form a protective crust, then chocolate infiltration is prevented, but additional time is required in the manufacturing process

Engineering Contradiction:

Improvecotton candy structureVSAvoidaging period

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The cotton candy ages itself in ambient or semi-humid conditions without requiring external intervention or controlled environment equipment. The hygroscopic nature of sugar causes moisture absorption and crust formation automatically, eliminating the need for specialized aging chambers or additional processing time while still achieving the protective effect.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If cotton candy strands are compressed to form a mass, then coating becomes feasible, but the fluffy texture may be compromised

Engineering Contradiction:

Improvecoating feasibilityVSAvoidfluffy texture

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The cotton candy is formed into a mass that maintains its internal fluffy structure while developing an external crust. The crust acts as a flexible protective shell that allows the mass to be handled and coated without compromising the delicate internal strands, resolving the contradiction between coating feasibility and texture preservation.

Inventive Principle:

Principle #30Flexible shells and thin films

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Preserves the fluffy texture of cotton candy while allowing it to be coated with chocolate, preventing infiltration and melting, and enabling the creation of stable chocolate truffles with a cotton candy filling.

Implementation Method 1

The sugar of the cotton candy is hygroscopic and absorbs moisture from the ambient environment both during forming and aging steps, forming a very thin crust of hydrated sugar that creates a barrier to infiltration of the liquid chocolate and also at least some protection against melting.

Methodology Applied

Scientific EffectHygroscopy: Absorption (physical)

AI summary

Truffles and other confections including cotton candy as a filling or as the outer shell of a filled confection are disclosed, as are methods of making such confections. In methods of making such confections, fresh cotton candy is shaped as needed, and then the shaped cotton candy is caused or allowed to form a thin crust of sugar that protects the inner mass of cotton candy from infiltration by chocolate or other coatings. The thin crust may be formed by a simple process, such as aging the formed cotton candy at appropriate conditions of temperature and humidity, or it may be formed by actively moistening the formed cotton candy. The resulting formed mass of cotton candy can be coated and finished. In some cases, shaped cotton candy may be formed around a filling and caused or allowed to form an outer crust, such that the cotton candy forms the outer layer of a truffle.
