Solution Overview

Problem

The production of high-quality chocolate couverture objects requires precise temperature control and specialized equipment, making it difficult for non-professionals to create chocolate objects at home without soiling and with lengthy processes.

Innovation Solution

A flexible, impermeable chocolate packaging with a closed contour and free space allows for heating and mixing of chocolate pieces to a pasty state, facilitating easy handling and tempering without specialized tools, and includes a method for stabilizing the chocolate through temperature treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If chocolate is heated in a saucepan and worked with a spatula or spoon, then the chocolate can be melted and mixed, but the work surface and hands get soiled and it requires strict hygiene conditions

Engineering Contradiction:
Improveease of chocolate handlingVSAvoidsoiling of work surface and hands
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a flexible pouch as an intermediary container to hold and manipulate chocolate pieces during heating and mixing. The pouch acts as a barrier between the chocolate and the user's hands/work surface, preventing soiling while allowing tactile manipulation and mixing through the pouch walls. This resolves the contradiction by enabling easy handling without direct contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent uses a flexible pouch made of thin, pliable material that can be easily manipulated by hand. The flexible nature of the pouch allows users to knead, press, and mix the chocolate pieces inside without direct contact, maintaining hygiene while preserving the tactile feedback needed for proper chocolate working. This directly addresses the soiling problem while maintaining ease of manufacture.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If traditional tempering equipment and procedures are used, then chocolate quality is maintained, but the process becomes complex and requires specialized knowledge

Engineering Contradiction:
Improvechocolate qualityVSAvoidspecialized equipment and procedures
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of tempering equipment (heating and mixing chocolate) from complex specialized machines and simplifies it to basic household items like a saucepan and the flexible pouch. By removing the need for professional tempering equipment while maintaining the core thermal processing steps, the invention makes quality chocolate working accessible without specialized knowledge.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flexible pouch enables the user to directly manipulate and mix the chocolate pieces through tactile feedback, providing self-service capability without requiring professional training. The pouch transmits the user's kneading and pressing actions to the chocolate inside, allowing intuitive control of the tempering process without complex equipment or specialized procedures.

Inventive Principle:
Principle #25Self-service

3Volume of stationary object

If chocolate pieces are tightly packed in a container, then storage space is optimized, but mixing becomes difficult when heated

Engineering Contradiction:
Improvestorage space efficiencyVSAvoidmixing ease
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The patent employs a dynamically flexible pouch that can adapt its volume and shape during different stages of use. During storage, the pouch can be compacted to optimize space. During heating and mixing, the pouch expands and becomes more pliable, allowing easy manipulation and kneading of the chocolate pieces. This dynamic adaptability resolves the contradiction between compact storage and easy mixing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The flexible pouch material allows the container to be easily deformed, stretched, and manipulated during the mixing phase. Users can knead, press, and work the chocolate pieces inside the pouch without difficulty, even after storage. The flexibility of the pouch walls transmits user forces effectively to the chocolate while allowing sufficient movement for thorough mixing, resolving the contradiction between compact storage and mixing ease.

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

Enables simple, clean, and quick production of homogeneous chocolate paste, allowing anyone to create chocolate objects at home with minimal equipment and hygiene concerns, while maintaining the quality of the chocolate.

Implementation Method 1

under the effect of the expansion of the volume of the gas (air) contained in the pocket in addition to the chocolate under the effect of the increase in temperature bringing the chocolate to the pasty state, the internal volume necessary for mixing is created

Methodology Applied
Scientific EffectThermal expansion: Thermal Expansion

Implementation Method 2

when the pieces of chocolate are heated until it reaches a pasty state

Methodology Applied
Scientific EffectHeating: Heating

Implementation Method 3

The chocolate coating is poured in a very fluid state on a support giving its final shape to the object when the chocolate is cooled to room temperature

Methodology Applied
Scientific EffectCooling: Cooling

AI summary

The chocolate package comprises a bag containing dissociated chocolate pieces. The bag is a flat pocket made from a flexible, waterproof material in which a continuous contour defines an interior seal container. The chocolate pieces occupy only a portion of the interior space so as to provide a space in the container allowing free mixing of chocolate pieces throughout the pocket, when the chocolate pieces are heated. Independent claims are included for: (1) a process for obtaining chocolate package; and (2) a process for manufacturing an object of chocolate cover.
