Solution Overview

Problem

Existing snus products face issues with initial mouth feel discomfort, fleece discoloration, flavor identification, inefficient tobacco feeding in pouching machines, and inconvenient disposal of used pouches, leading to reduced consumer satisfaction and increased production costs.

Innovation Solution

The development of a smokeless tobacco product with a granular tobacco composition enclosed in a water-permeable pouch treated with miraculin, along with improved packaging features such as a container with an onsert for used pouch storage and a modified pouching machine design to enhance tobacco flow, addresses these issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional fleece material is used for snus pouches, then the pouch structure is simple and inexpensive, but the fleece exhibits discoloration after storage and provides uncomfortable initial mouth feel

Engineering Contradiction:
Improvepouch manufacturing simplicityVSAvoidfleece color stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The fleece material is pre-treated with discoloration inhibitors and coatings during manufacturing before the snus tobacco is added. This preliminary treatment prevents yellowing from occurring during storage, addressing the color stability issue while maintaining manufacturing efficiency through a single-step process integration.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If conventional fleece material is used for snus pouches, then the pouch structure is simple and inexpensive, but the initial mouth feel is uncomfortable

Engineering Contradiction:
Improvepouch manufacturing simplicityVSAvoidinitial mouth feel discomfort
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The fleece is pre-coated with substances that modify the initial mouth feel before the product is assembled. This preliminary treatment ensures comfortable sensation upon first use while maintaining the simplicity of the overall manufacturing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The surface properties of the fleece are modified through chemical or physical treatment to change parameters such as softness, texture, or moisture interaction, thereby improving mouth feel comfort without fundamentally altering the pouch structure or manufacturing approach.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If all snus flavors are packaged in white pouches, then the packaging is uniform and simple, but different flavors cannot be easily distinguished

Engineering Contradiction:
Improvepackaging uniformityVSAvoidflavor identification
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

Different flavor variants are assigned distinct color codes or color accents on the pouch packaging. This allows consumers to easily identify flavors at a glance while maintaining the overall simplicity and uniformity of the white pouch base design, preventing information loss about flavor differentiation.

Inventive Principle:
Principle #32Color changes

4Productivity

If high-speed pouching equipment with standard hopper design is used, then production speed is high, but dead zones and rat holes cause product flow loss and require regular cleaning

Engineering Contradiction:
Improvepouching production speedVSAvoidtobacco material flow loss
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The hopper is equipped with vibratory elements or vibration mechanisms that periodically agitate the tobacco material, preventing it from settling into dead zones or forming rat holes. This maintains continuous flow at high production speeds while minimizing material loss and reducing the frequency of manual cleaning interventions.

Inventive Principle:
Principle #18Mechanical vibration

5Productivity

If high-speed pouching equipment with standard hopper design is used, then production speed is high, but dead zones and rat holes require regular cleaning which lowers production efficiency

Engineering Contradiction:
Improvepouching production speedVSAvoidcleaning maintenance time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Vibration mechanisms continuously or periodically agitate the tobacco in the hopper, preventing material stagnation and eliminating dead zones. This reduces or eliminates the need for manual cleaning interruptions, thereby maintaining high production speeds without sacrificing time to maintenance activities.

Inventive Principle:
Principle #18Mechanical vibration

Solution Approach 2:

The vibration system operates continuously or in periodic cycles during production to maintain optimal material flow conditions throughout the hopper. This ensures uninterrupted tobacco feeding to the pouching mechanism, eliminating downtime for cleaning and maintaining continuous productive operation.

Inventive Principle:
Principle #20Continuity of useful action
