Solution Overview

Problem

Traditional gum processing methods are time-consuming and require significant machinery, often resulting in non-uniform outputs and high energy consumption, particularly due to the need for multiple size reduction rollers and high shear extruders which can damage shear-sensitive ingredients.

Innovation Solution

A method using a pair of rollers with a horizontally and vertically offset arrangement to size gum into a uniform sheet, eliminating the need for multiple rollers and high shear extruders, allowing for wider gum production with reduced energy consumption and preserving sensitive ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional multiple size reduction rollers are used to reduce gum thickness, then the gum can be reduced to desired thickness, but the process becomes time-consuming and energy-intensive

Engineering Contradiction:
Improvegum thickness uniformityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent combines multiple size reduction rollers into a single pair of rollers that perform the entire thickness reduction process in one operation. The first and second rollers are positioned to receive gum material and reduce its thickness simultaneously, eliminating the need for sequential rolling operations through multiple rollers, thereby reducing processing time while maintaining thickness uniformity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent divides the gum processing into distinct functional zones: a first region where gum material is received and a second region where thickness reduction occurs. This spatial segmentation allows the single pair of rollers to perform multiple functions (receiving, reducing, and uniformizing thickness) that traditionally required multiple sequential operations, reducing overall processing time.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If high shear extruders are used to force gum through small orifices, then the gum can be formed into desired shapes, but shear-sensitive ingredients are damaged

Engineering Contradiction:
Improvegum shape and size controlVSAvoiddamage to shear-sensitive ingredients
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the high-shear mechanical action of traditional extruders with a gentle rolling mechanism. Instead of forcing gum through small orifices using high shear forces, the gum material is passed between the first and second rollers which gradually reduce thickness through contact pressure, preserving shear-sensitive ingredients while achieving the desired shape and size control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the mechanical parameters from high shear force to low shear contact pressure. The rollers are designed to apply gradual, distributed pressure across the gum material surface, reducing thickness through compression rather than shear, thereby protecting shear-sensitive ingredients while maintaining precise control over final gum dimensions.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If a series of sizing rollers are used to progressively reduce gum thickness, then the gum can be reduced from thick to thin, but the equipment complexity increases

Engineering Contradiction:
Improvegum thickness controlVSAvoidnumber of rollers required
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple sizing rollers into a single pair of rollers. The first and second rollers are positioned and configured to perform the entire thickness reduction sequence that would traditionally require multiple rollers, simplifying the equipment while maintaining precise thickness control through their specific geometric arrangement and gap settings.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single pair of rollers is designed to perform multiple functions simultaneously: receiving thick gum material, progressively reducing thickness, and producing uniformly thin gum sheets. This multi-functionality eliminates the need for separate receiving rollers, intermediate sizing rollers, and finishing rollers, thereby reducing device complexity while maintaining manufacturing precision.

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

4Productivity

If traditional rolling and scoring lines with multiple rollers are used, then gum can be processed into final product, but energy consumption is high

Engineering Contradiction:
Improvegum production outputVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple energy-intensive rolling operations into a single pair of rollers that complete the entire thickness reduction process in one pass. By eliminating the need for multiple sequential rolling operations through additional rollers, the system maintains high productivity while significantly reducing total energy consumption associated with driving multiple motorized rolling components.

Inventive Principle:
Principle #5Merging (Combining)
