Solution Overview

Problem

Existing methods for creating marbled chocolate coatings for confectionery fail to produce coatings that are both visually appealing and thin enough for a pleasant taste experience, while also maintaining an attractive shine and quality indication.

Innovation Solution

An automated method using an air flow device to distribute and blend different colored chocolates in a mold, creating a marbled effect with controlled pressure and temperature, resulting in a thin, glossy coating with a nice transition between colors, and incorporating a recycling system for optimal chocolate use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional methods are used to create marbled chocolate coating, then the coating has sufficient thickness for structural integrity, but the coating becomes too thick to bite through easily and loses taste appeal

Engineering Contradiction:
Improvecoating thickness controlVSAvoidbite-through ease
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The coating process is divided into multiple sequential layers: a first layer of first-colored chocolate is applied, then a second layer of second-colored chocolate is applied on top. This segmentation allows each layer to be thin individually while creating a visually appealing marbled effect when combined, solving the contradiction between sufficient coating thickness for integrity and thinness for easy biting.

Inventive Principle:
Principle #1Segmentation

2Illumination intensity

If more chocolate is used to create vibrant marbled colors, then the visual appeal improves, but the coating thickness increases making it difficult to bite through

Engineering Contradiction:
Improvecolor vibrancyVSAvoidcoating thickness
Core Design Contradiction:
Illumination intensityVSLength of moving object

Solution Approach 1:

Different colored chocolate layers are applied to different regions or sequences, creating local color variations that produce the marbled effect. The first-colored chocolate forms a base layer in certain areas, while the second-colored chocolate forms layers in other areas or on top, allowing vibrant color display without requiring excessive overall thickness.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the coating is made thinner for better taste experience, then the ease of biting improves, but the coating loses structural integrity and shine

Engineering Contradiction:
Improvebite-through easeVSAvoidcoating integrity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The first layer of first-colored chocolate is applied and allowed to partially set or form a stable base before applying the second layer of second-colored chocolate. This preliminary action ensures that each thin layer maintains its structural integrity individually, while the combined multi-layer structure provides both the thinness needed for easy biting and the structural strength required for coating reliability.

Inventive Principle:
Principle #10Preliminary action
