High-Density Compressed Cellulose Towel Stack for Efficient Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transporting cellulose-containing absorbent towels result in high bulk due to air pockets between sheets, leading to inefficient use of space and increased logistics and environmental impacts, with a need to reduce stack volume without compromising dispensing performance or towel functionality.
Innovation Solution
A stack of cellulose-containing absorbent towels is compressed to achieve high densities (at least 0.25 g/cm3) using specific manufacturing processes and material choices, allowing for separable towels that maintain absorption and wet strength, enabling reduced dispenser size or increased capacity while optimizing logistics and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If towels are heavily compressed to reduce bulk, then transportation efficiency and storage density improve, but dispensing performance and towel separability may deteriorate
Solution Approach 1:
The patent applies parameter changes by controlling the moisture content of towels before compression (maintaining 3-15% moisture) and optimizing compression pressure (5-50 bar) to achieve high density while preserving towel separability and dispensing performance
Solution Approach 2:
The patent applies preliminary action by pre-moistening the towels to optimal moisture levels before compression, which prepares the material structure to maintain separability even after heavy compression during transportation
2Volume of stationary object
If towels are heavily compressed to reduce bulk, then transportation efficiency and storage density improve, but absorption capacity and wet strength may deteriorate
Solution Approach 1:
The patent applies parameter changes by optimizing moisture content (3-15%) and compression pressure (5-50 bar) to achieve high density while preserving the cellulose material's absorption capacity and wet strength properties
Solution Approach 2:
The patent applies composite materials by using cellulose-based towels with specific material composition that maintains functional properties even under high compression density (0.25-0.60 g/cm³)
3Ease of operation
If traditional low-density stacking is used, then towel separability and dispensing performance are maintained, but transportation efficiency and storage utilization deteriorate
Solution Approach 1:
The patent applies parameter changes by optimizing moisture content (3-15%) and compression pressure (5-50 bar) to achieve high density (0.25-0.60 g/cm³) while preserving towel separability and dispensing performance
Solution Approach 2:
The patent applies preliminary action by pre-moistening towels to optimal levels before compression, which enables the towels to be heavily compressed for efficient transportation while still maintaining ease of separation when needed
