Solution Overview
Problem
Cellulose products made using air-formed cellulose blank structures face challenges with water absorption and mechanical strength, limiting their durability and resistance to liquids, and often require plastic laminates for protection, which is not environmentally friendly.
Innovation Solution
A method involving the incorporation of a barrier chemistry composition (BCC) into the cellulose blank structure during the air-forming process, controlling its distribution to maintain mechanical strength while creating a barrier against water and other substances, eliminating the need for plastic laminates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air-formed cellulose blank structures are used to produce cellulose products, then the manufacturing process is simplified and productivity is improved, but the products have poor resistance to liquids and moisture, limiting their durability
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition parameters of the cellulose product through incorporation of barrier chemistry composition (BCC). This changes the material properties to achieve both liquid resistance and maintained productivity, resolving the contradiction between manufacturing efficiency and durability.
Solution Approach 2:
The patent creates a composite material system by combining cellulose fibres with barrier chemistry composition (BCC). This composite structure provides both the manufacturing advantages of air-formed cellulose and the liquid resistance properties needed for durability, eliminating the need for plastic laminates.
2Reliability
If plastic films are laminated to cellulose products to prevent liquid absorption, then resistance to liquids is improved, but environmental friendliness deteriorates due to use of plastic materials
Solution Approach 1:
The patent extracts and eliminates the harmful plastic laminate component from the traditional solution. Instead of adding plastic films to cellulose products, the invention incorporates barrier chemistry composition directly into the cellulose matrix, achieving liquid resistance without environmental harm.
Solution Approach 2:
The patent changes the chemical composition parameters of the cellulose product by incorporating BCC, transforming it from a naturally absorbent material to a liquid-resistant material. This parameter change provides the needed protection without requiring external plastic laminates, thus avoiding environmental harm.
3Reliability
If barrier chemistry composition is incorporated into cellulose blank structure, then resistance to liquids is improved, but mechanical strength may be compromised
Solution Approach 1:
The patent carefully controls the concentration and distribution parameters of the barrier chemistry composition within the cellulose structure. By optimizing these parameters, the invention achieves liquid resistance while maintaining adequate mechanical strength, resolving the contradiction between protection and structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method enhances the cellulose products' resistance to liquids and moisture without compromising mechanical properties, allowing them to maintain strength and functionality over longer periods without the use of plastic materials.
Implementation Method 1
the BCC forms a barrier structure that is preventing water from being absorbed in the cellulose fibre structure of the cellulose products
Implementation Method 2
the mechanical strength, flexibility, and chemical properties are limited. It is also difficult in wet-forming processes to control the mechanical properties of the cellulose products with high precision
