Solution Overview

Problem

Tobacco products are prone to microbial contamination and infestation, leading to flavor changes, quality degradation, and reduced shelf life, with existing sterilization methods like heat pasteurization being inefficient and potentially causing oxidative degradation.

Innovation Solution

The use of electron beam (E-Beam) treatment, which applies high-energy electrons to reduce microbial populations and pests in tobacco, thereby stabilizing the product without causing oxidative damage and preventing the formation of nitrosamines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If heat pasteurization is used to reduce microorganisms and pests in tobacco, then microbial contamination is reduced, but oxidative degradation occurs and product quality deteriorates

Engineering Contradiction:

Improvemicrobial contamination levelVSAvoidoxidative degradation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the thermal field (heat pasteurization) with an electron beam field to achieve sterilization. The electron beam treatment delivers high-energy electrons that directly damage microbial DNA and cellular structures, eliminating the need for high-temperature heating that causes oxidative degradation in tobacco products.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the sterilization parameter from temperature (heat pasteurization at 175-200°F) to energy dose (electron beam dosage). This parameter transformation allows effective microbial elimination without the thermal side effects of oxidative degradation, preserving tobacco quality while achieving the same sterilization objective.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If heat pasteurization is used to eliminate microorganisms, then microbial levels are reduced, but processing time increases and productivity decreases

Engineering Contradiction:

Improvemicroorganism eliminationVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent substitutes the slow thermal sterilization process with rapid electron beam irradiation. The electron beam delivers sterilization effects instantaneously through direct cellular damage, reducing processing time from minutes (heat pasteurization) to seconds, thereby significantly improving productivity while maintaining effective microorganism elimination.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If chemical treatments are used to control insect infestation, then pest damage is reduced, but resistance development occurs and reliability decreases

Engineering Contradiction:

Improveinsect infestationVSAvoidpest control effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent replaces chemical pest control with physical electron beam sterilization. The electron beam directly damages the genetic material and cellular structures of insects, larvae, and eggs, providing a non-chemical method that eliminates pests without the development of resistance that occurs with repeated chemical treatments.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If traditional sterilization methods are used to stabilize tobacco, then microbial populations are reduced, but nitrite formation increases and product quality deteriorates

Engineering Contradiction:

Improvemicrobial population reductionVSAvoidnitrite formation

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent substitutes thermal sterilization with electron beam treatment, which eliminates microbes through direct cellular damage without the chemical byproducts of heat treatment. This method reduces microbial populations while preventing nitrite formation, as the electron beam does not promote the chemical reactions that generate nitrites in tobacco products.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
