Solution Overview

Problem

The confectionery industry faces challenges in producing chocolate eggs with adequate mechanical resistance using a reduced quantity of chocolate and/or pastry cream, while minimizing calorie content and preventing chocolate from sticking to packaging, and ensuring clean consumption.

Innovation Solution

The solution involves creating chocolate and/or pastry cream eggs with two half-shells, where the internal shells have a uniform thickness increase along the perimeter edge and are externally covered by wafer biscuit half-shells with a uniform thickness decrease, optimized by a discontinuity in the radius of curvature, allowing for mechanical resistance without excessive chocolate usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the thickness of chocolate is increased to provide mechanical resistance, then the strength of the egg shell is improved, but the quantity of chocolate used increases leading to higher cost and calorie content

Engineering Contradiction:
Improvemechanical resistanceVSAvoidquantity of chocolate
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The egg shell is divided into two distinct layers: an internal chocolate/pastry cream half-shell and an external wafer biscuit half-shell. This segmentation allows each material to perform its optimal function - the chocolate provides structural integrity while the wafer provides protective coverage, reducing the total quantity of chocolate needed while maintaining mechanical resistance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses a composite structure combining chocolate/pastry cream with wafer biscuit. This composite material approach allows the weaker chocolate layer to be thinner since the wafer layer compensates for mechanical strength, thereby reducing the quantity of chocolate used while maintaining adequate mechanical resistance.

Inventive Principle:
Principle #40Composite materials

2Quantity of substance

If the thickness of chocolate is reduced to lower cost and calorie content, then the quantity of chocolate used decreases, but the mechanical resistance of the egg shell deteriorates

Engineering Contradiction:
Improvequantity of chocolateVSAvoidmechanical resistance
Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

By segmenting the shell into internal chocolate layer and external wafer layer, the chocolate can be used in reduced quantities while the wafer layer compensates for mechanical strength requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The composite structure of chocolate/pastry cream combined with wafer biscuit allows reduction of chocolate thickness since the wafer provides additional structural support, maintaining mechanical resistance with lower chocolate quantity.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If chocolate is used as the outer packaging material, then the egg can be formed and joined easily, but the chocolate sticks to the packaging wrapper and gets on hands and lips during consumption

Engineering Contradiction:
Improveforming and joiningVSAvoidsticking to packaging and hands
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The wafer biscuit layer is extracted as an external covering that separates the consumer's hands/lips from the chocolate, eliminating the harmful sticking effect while preserving chocolate's ease of manufacture properties for the internal structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The wafer biscuit acts as an intermediary layer between the chocolate and the external environment (packaging and consumer contact), preventing direct contact and sticking while allowing the chocolate to maintain its manufacturing advantages.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If the thickness of chocolate is increased to prevent sticking to packaging at elevated temperatures, then the mechanical resistance is improved, but the quantity of chocolate and calorie content increase

Engineering Contradiction:
Improveprevention of stickingVSAvoidquantity of chocolate
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The wafer layer is extracted as an external protective barrier that prevents chocolate from contacting packaging surfaces, eliminating the sticking problem without requiring increased chocolate thickness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The wafer biscuit serves as an intermediary barrier between the chocolate and packaging wrapper, preventing direct contact and sticking at elevated temperatures while allowing the chocolate layer to remain thin.

Inventive Principle:
Principle #24Intermediary (Mediator)
