Solution Overview

Problem

Existing smokeless oral products, such as snuff and snus, often cause irritation at the back of the throat and have a dense, compact structure that affects user experience and mouthfeel.

Innovation Solution

Incorporating a particulate material with specific properties, including a mass median particle size of 0.3 mm to 3 mm, bulk density less than 0.6 g/cm³, and a combined starch and sugar content of less than 7%, into smokeless oral products to improve mouthfeel and reduce throat irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a dense, compact structure is used in smokeless oral products, then the product maintains its shape and stability, but it causes irritation at the back of the throat and poor mouthfeel

Engineering Contradiction:
Improvethroat irritationVSAvoidproduct structure stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The product is divided into discrete particles with specific size ranges (0.3-3mm mass median particle size). This segmentation creates a less dense overall structure that reduces throat irritation while maintaining individual particle stability. The particulate material forms a heterogeneous mixture that prevents the dense compact structure associated with throat irritation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the product have different properties - the particulate material provides localized softness and springiness at the particle level, while the overall product maintains structural stability through the specific particle size distribution and density characteristics. This local quality differentiation allows simultaneous improvement of mouthfeel and structural stability.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If particulate material with specific properties is added to improve mouthfeel, then user experience is enhanced, but the product composition becomes more complex

Engineering Contradiction:
Improvemouthfeel qualityVSAvoidproduct composition complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention specifies particular parameter ranges for the particulate material (particle size 0.3-3mm, bulk density <0.6 g/cm³, starch+sugar content <7%) to achieve improved mouthfeel. By controlling these physical and chemical parameters within defined ranges, the product achieves desirable sensory properties while maintaining compositional simplicity through natural particulate materials.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The product combines tobacco or tobacco analogue material with particulate material to create a composite formulation. This composite approach integrates the functional properties of tobacco with the textural benefits of particulate material, achieving enhanced mouthfeel through material composition rather than complex processing or multiple additives.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If the particle size is reduced to improve texture, then the mouthfeel becomes softer, but the bulk density increases and throat irritation worsens

Engineering Contradiction:
Improvetexture softnessVSAvoidbulk density
Core Design Contradiction:
Ease of operationVSWeight of stationary object

Solution Approach 1:

The invention employs a dynamic particle size distribution rather than a single fixed size. The mass median particle size range of 0.3-3mm allows flexibility in achieving both soft texture and acceptable bulk density. This dynamic range enables optimization of both texture softness and bulk density depending on specific product requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention addresses the density-texture tradeoff by introducing particle shape and size distribution as additional dimensions of control. Rather than simply reducing particle size (one dimension), the patent utilizes the three-dimensional characteristics of particulate material including size distribution, shape, and packing arrangement to achieve soft texture while maintaining lower bulk density through optimized particle morphology.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
