Solution Overview

Problem

Confectionery products without a chocolate shell are more perishable and less attractive due to the absence of a protective barrier against temperature and contaminants, leading to structural integrity issues and reduced consumer appeal.

Innovation Solution

A wafer shell made from a batter containing cocoa powder with a higher weight percentage and a glossy surface, providing a denser and protective barrier similar to chocolate, is used to encase a filling, with a process involving specific batter composition and mould surface treatment to achieve a lustre value of at least 20 gloss.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a wafer shell without chocolate is used, then the product is less sensitive to temperature and avoids chocolate melting issues, but the product becomes more perishable and less attractive due to absence of protective barrier and visual appeal

Engineering Contradiction:
Improvetemperature sensitivityVSAvoidproduct perishability
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent changes the physical and chemical parameters of the wafer by incorporating cocoa powder (at least 3 wt%) and controlling the batter composition to achieve a glossy surface with lustre value of at least 20 gloss. This transforms the wafer from a matte, porous structure to a dense, shiny structure that visually resembles chocolate while maintaining temperature stability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite wafer material combining traditional wafer ingredients (flour, sugar, water) with cocoa powder to produce a shell that exhibits both the structural properties of wafer and the visual appearance of chocolate, achieving a hybrid material with dual functionality

Inventive Principle:
Principle #40Composite materials

2Temperature

If a wafer shell without chocolate is used, then the product avoids chocolate melting at high temperatures, but the outer surface lacks the protective barrier against contaminants and filling leakage

Engineering Contradiction:
Improveheat resistanceVSAvoidcontaminant infiltration
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

By modifying the wafer composition to include cocoa powder and adjusting the batter parameters, the patent creates a denser wafer structure with reduced porosity. This structural change provides the protective barrier function against contaminant infiltration while maintaining heat resistance

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The composite wafer material combines the barrier properties needed to prevent contaminant infiltration with the thermal stability of wafer, creating a shell that simultaneously protects against both heat and contaminants

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If a wafer shell without chocolate is used, then the product maintains structural integrity at various temperatures, but the consumer appeal and visual attraction are reduced

Engineering Contradiction:
Improvestructural integrityVSAvoidvisual appeal
Core Design Contradiction:
Stability of the object's compositionVSIllumination intensity

Solution Approach 1:

The patent changes the surface parameters of the wafer by controlling the batter composition and baking conditions to achieve a glossy surface with lustre value of at least 20 gloss. This visual transformation enhances consumer appeal while the underlying dense structure maintains structural integrity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

By incorporating cocoa powder into the wafer batter, the patent changes the color of the wafer shell to resemble chocolate, creating visual appeal and consumer attraction while maintaining the structural benefits of wafer

Inventive Principle:
Principle #32Color changes

4Reliability

If cocoa powder is added to the wafer batter, then the wafer shell gains protective barrier properties and visual appeal, but the manufacturing process requires precise control of batter composition and mould surface treatment

Engineering Contradiction:
Improveprotective barrier functionVSAvoidbatter composition control
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent specifies precise parameter ranges for the batter composition (cocoa powder at least 3 wt%, water at least 40 wt%) and mould surface roughness (Ra ≤ 1.2 μm) to achieve the desired glossy surface and protective barrier function, transforming the manufacturing process into a controlled parameter-based system

Inventive Principle:
Principle #35Parameter changes
