Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smokeless tobacco products face challenges in achieving reduced density without compromising sensory characteristics, leading to increased manufacturing and transportation costs, as well as environmental impact.
Innovation Solution
Incorporating a combination of high-density and low-density non-tobacco cellulosic materials, such as microcrystalline cellulose and bamboo fibers, along with active ingredients and flavorants, to create oral products with a filler content of at least 20% by weight, enhancing texture and mouthfeel while reducing overall weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional smokeless tobacco products use high-density tobacco material, then sensory characteristics are maintained, but manufacturing and transportation costs increase and environmental impact worsens
Solution Approach 1:
The patent applies composite materials by combining tobacco material with non-tobacco cellulosic materials (such as microcrystalline cellulose, bamboo fiber, wheat straw fiber) to create a filler blend. This composite approach allows the product to reduce density and associated costs while maintaining sensory characteristics through the synergistic properties of the mixed materials. The cellulosic fillers provide bulk and texture similar to tobacco, enabling cost reduction without significant sensory compromise.
Solution Approach 2:
The patent implements parameter changes by modifying the density parameter of the product composition. By incorporating low-density cellulosic materials (density ranging from 0.1 to 1.5 g/cm³, preferably 0.3 to 0.8 g/cm³) into the tobacco blend, the overall product density is reduced. This parameter change directly addresses the contradiction by lowering manufacturing and transportation costs while the careful selection of cellulosic materials ensures sensory characteristics are preserved.
2Ease of manufacture
If filler content is increased to reduce density, then manufacturing costs decrease, but product composition stability deteriorates
Solution Approach 1:
The patent applies parameter changes by optimizing the filler content within a specific range (20% to 80% by weight, preferably 30% to 60%). This controlled parameter adjustment allows sufficient density reduction for cost savings while maintaining composition stability. The specified ranges ensure that the product retains adequate tobacco content for sensory quality while incorporating enough cellulosic filler for cost reduction, balancing both requirements.
Solution Approach 2:
The use of composite materials with carefully selected proportions helps maintain composition stability. The combination of tobacco material and non-tobacco cellulosic materials creates a synergistic blend where each component compensates for the other's limitations. The cellulosic fillers provide structural stability and bulk, while the tobacco material maintains sensory properties, resulting in a stable composite composition that is easier and cheaper to manufacture.
3Weight of moving object
If low-density cellulosic materials are used, then product weight is reduced, but sensory characteristics may be compromised
Solution Approach 1:
The patent uses composite materials to balance weight reduction with sensory quality maintenance. By blending low-density cellulosic materials (such as bamboo fiber, microcrystalline cellulose) with tobacco material in optimized proportions, the product achieves reduced weight while the tobacco component preserves essential sensory characteristics. The cellulosic fillers contribute texture and bulk without significantly compromising taste or mouthfeel when used within the specified ranges.
Solution Approach 2:
The patent applies local quality by assigning different functional roles to different components in the composite. The tobacco material primarily provides sensory characteristics, while the cellulosic fillers primarily provide bulk and weight reduction. This functional differentiation allows each component to excel at its designated role, achieving weight reduction without sacrificing sensory quality where it matters most.
