Solution Overview

Problem

Current chewing gum products lack variability in texture and processing efficiency, with existing methods failing to consistently produce chewing gums with desired physical-chemical characteristics such as chewiness, stickiness, bubble-blowing capability, flavor release, and cooling sensation across different textures.

Innovation Solution

A chewing gum composition comprising 10-35% gum base and 50-80% bulk sweetener blend, with xylitol, sorbitol, and isomalt or maltitol, processed to achieve specific viscosity ratios and temperatures to create soft, intermediate, or crisp textures, involving a method that includes heating, mixing, and depositing a molten gum mixture to form the product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional chewing gum formulations and processing methods are used, then production is simple and cost-effective, but texture variability and consistency of physical-chemical characteristics are insufficient

Engineering Contradiction:
Improveconsistency of physical-chemical characteristicsVSAvoidprocessing method complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by precisely controlling the viscosity ratio between gum base and polyol at different processing stages. The viscosity ratio is adjusted from an initial range of 1:1 to 1:3 during mixing, then to 1:10 to 1:20 during deposition, enabling consistent texture and physical-chemical characteristics across different chewing gum products.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transitions by heating the gum base and polyol mixture to transition from solid to molten state, achieving a homogeneous molten mixture with controlled viscosity. This phase transition enables proper mixing and deposition while ensuring consistent product characteristics upon cooling and solidification.

Inventive Principle:
Principle #36Phase transitions

2Adaptability or versatility

If multiple texture types (soft, intermediate, crisp) are produced using different formulations, then texture variability is improved, but manufacturing complexity and process control difficulty increase

Engineering Contradiction:
Improvetexture varietyVSAvoidmanufacturing process simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent achieves universality by using a single core processing method that produces multiple texture types (soft, intermediate, crisp) through controlled parameter adjustments. The same basic process of mixing at viscosity ratio 1:1 to 1:3 and depositing at viscosity ratio 1:10 to 1:20 can produce different textures by varying gum base composition and polyol content, eliminating the need for separate manufacturing lines for each texture type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Different textures are achieved by changing the initial formulation parameters while maintaining the same processing methodology. Soft gum uses higher polyol content (viscosity ratio 1:3), intermediate gum uses balanced proportions, and crisp gum uses lower polyol content (viscosity ratio 1:1), all processed through the same controlled viscosity ratio method.

Inventive Principle:
Principle #35Parameter changes

3Strength

If high polyol content (50-80%) is used to improve chewiness and texture, then sensory properties are enhanced, but processing viscosity control and product consistency become more difficult

Engineering Contradiction:
ImprovechewinessVSAvoidviscosity control precision
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The patent manages viscosity control by dynamically adjusting the viscosity ratio parameter throughout processing. Despite high polyol content (50-80%), the viscosity ratio is controlled at 1:1 to 1:3 during mixing and 1:10 to 1:20 during deposition, ensuring proper flow and consistency. This parameter control enables enhanced chewiness from high polyol content while maintaining manufacturing precision.

Inventive Principle:
Principle #35Parameter changes
