Solution Overview

Problem

Current methods for coloring eggs with multiple colors are inefficient and unsafe, as they often require non-food-safe materials or result in the alteration of the original color, making it difficult to achieve clean, multicolored designs without distorting the lines or using hazardous products.

Innovation Solution

A food-safe coating is developed by mixing an edible salt compound with water and hydroxide, optionally adding an acid and sugar alcohol, and incorporating a food-grade emulsifier and wax, which is applied to the eggshell to prevent dye penetration, allowing for the creation of multiple colored designs using stickers and repeated dyeing processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wax or petroleum products are used to prevent dye penetration, then the effectiveness of preventing dye penetration is improved, but the safety for children and consumers deteriorates

Engineering Contradiction:
Improvedye penetration prevention effectivenessVSAvoidconsumer safety
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters of the barrier material from non-edible wax and petroleum products to edible ingredients including oils, sugars, and starches. This parameter change maintains the barrier function while improving consumer safety and edibility for Easter egg decorating.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses food-grade materials that are inherently safe for consumption, eliminating the need for separate non-toxic barrier materials. The coating is applied temporarily during the dyeing process and then removed or consumed along with the egg, providing a safe disposable barrier solution.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Adaptability or versatility

If stickers are used to mask areas before dyeing, then the ability to create multi-colored designs is improved, but the original color changes and lines become distorted

Engineering Contradiction:
Improvemulti-colored design capabilityVSAvoidline clarity and color stability
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies a removable coating to specific areas of the eggshell before the dyeing process. This preliminary action creates a protective barrier that prevents dye penetration in desired areas, allowing for precise multi-colored designs without the need for stickers that distort lines or change original colors.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a removable coating as an intermediary material between the eggshell and the dye. This coating acts as a temporary barrier that can be precisely applied and removed, enabling clean line work and accurate color placement without the drawbacks of sticker-based methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If wax crayons or melted wax are used for local dye prevention, then the ability to write on eggs is improved, but the efficiency and acceptability of results deteriorate

Engineering Contradiction:
Improvewriting capability on eggsVSAvoiddecorating efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent changes the physical state and application method of the barrier material from solid wax crayons to a liquid or semi-liquid removable coating that can be easily applied with brushes or other tools. This parameter change improves both the ease of operation and the efficiency of the decorating process while maintaining the ability to create precise designs.

Inventive Principle:

AI summary

The method is for making a coating for use in reducing penetration of food dyes on an egg shell surface. The method includes admixing an edible salt compound with water in combination with a hydroxide, optionally adding an acid to lower the pH of the mixture; optionally adding a sugar alcohol; optionally adding, and mixing in, one or more of water and a food grade acid, bacterial alpha amylase, a plasticizer, a sugar, starch, cellulose/cellulose esters, gelatin, agar, gluten, casein, and protein, adding a food grade emulsifier and a fatty acid to the mixture, optionally adding a food grade clay to the mixture, heating the mixture to a temperature between 135-200° F. and adding a food grade wax, and optionally adding a silicone, cooling the mixture to produce the coating for application onto the egg shell surface.
