Solution Overview

Problem

Existing methods for manufacturing water-containing heat-resistant chocolate face challenges in maintaining a suitable viscosity level of the chocolate mix in a molten state during molding, leading to difficulties in handling and quality deterioration.

Innovation Solution

The method involves adding a seeding agent containing β-form XOX crystals to the chocolate mix at a temperature range of 32 to 40°C, along with water, to suppress viscosity increase and form a saccharide skeleton, thereby maintaining the chocolate's heat resistance and shape retention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water is added to chocolate mix in a molten state before molding, then heat resistance and shape retention are improved by forming a saccharide skeleton, but the viscosity of the chocolate mix significantly increases causing drastic deterioration of handleability

Engineering Contradiction:
Improveheat resistanceVSAvoidhandleability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by adding a seeding agent containing β-form XOX crystals to the chocolate mix before adding water. This pre-seeding establishes a crystal framework that controls subsequent water addition, allowing the saccharide skeleton to form without causing excessive viscosity increase. The seeding agent prepares the system in advance to handle water addition properly.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the physical-chemical parameters of the chocolate mix by introducing a specific seeding agent with defined crystal structure (β-form XOX). This parameter change modifies how the mix responds to water addition, enabling heat resistance improvement while maintaining manageable viscosity levels through controlled crystallization.

2Shape

If water is added to chocolate mix to form a saccharide skeleton, then shape retention is improved, but the viscosity increase makes molding difficult

Engineering Contradiction:
Improveshape retentionVSAvoidmolding process complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The seeding agent is added in advance to establish a crystal framework before water addition. This preliminary crystallization structure enables the saccharide skeleton to form with proper shape retention while avoiding the viscosity spikes that would complicate the molding process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The seeding agent acts as an intermediary between water addition and saccharide skeleton formation. It mediates the interaction by providing a template that guides water integration, achieving shape retention without the harmful viscosity increases that would complicate molding operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If emulsifiers are used to delay viscosity increase, then handleability is improved, but the viscosity control cannot be maintained for a long time

Engineering Contradiction:
ImprovehandleabilityVSAvoidviscosity stability duration
Core Design Contradiction:
Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The patent changes the fundamental parameter of crystallization by introducing a specific seeding agent with β-form XOX crystals. This parameter change creates a stable, long-lasting viscosity control mechanism that works through controlled crystallization rather than emulsification, maintaining handleability for extended periods.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The seeding agent enables the chocolate mix to self-regulate its viscosity through controlled crystallization. The β-form XOX crystals provide a self-sustaining framework that maintains handleability over time without requiring continuous external intervention or additional additives.

Inventive Principle:
Principle #25Self-service
