Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the tissue industry, large cores with sensitive casing materials are often damaged during manual cleaning, making reuse impossible, and there is a need for a method to restore used cores without causing damage.
Innovation Solution
A device featuring a rubber or rubber-like wheel or hook is used to gently remove material residues from the core, avoiding direct contact with the sensitive casing surface, and combining this with a core cleaner or roll cutter to split and remove the tissue, ensuring the core is restored without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning with knives is used, then material residues can be removed from the core, but the sensitive casing material is damaged making reuse impossible
Solution Approach 1:
The patent replaces the manual mechanical knife cleaning system with an automated mechanical wheel system that uses controlled friction and abrasion to remove material residues. The wheel, driven by a motor, automatically traverses the core surface with adjustable pressure, substituting manual knife operations with a controlled mechanical process that removes residues without damaging the casing material.
Solution Approach 2:
The patent changes the parameters of the cleaning process by controlling the wheel's rotational speed, axial traversal speed, and applied pressure. These parameters are adjusted to optimize the removal of material residues while maintaining the integrity of the casing material, resolving the contradiction between effective cleaning and damage prevention.
2Extent of automation
If automatic cleaning is implemented, then cleaning speed and consistency improve, but risk of damaging sensitive casing material increases
Solution Approach 1:
The patent employs a dynamically controllable wheel system where the rotational speed and axial movement can be adjusted during operation. The wheel's contact pressure with the core is dynamically regulated to remove material residues effectively while preventing damage to the casing material, allowing automatic cleaning without increasing damage risk.
Solution Approach 2:
The system incorporates feedback control mechanisms that monitor the cleaning process and adjust wheel parameters in real-time. This feedback ensures that the automated cleaning process maintains optimal pressure and speed, removing residues thoroughly while preventing excessive force that could damage the sensitive casing material.
3Productivity
If aggressive cleaning methods are used, then material residues are removed more effectively, but the core cannot be reused due to casing damage
Solution Approach 1:
The patent uses controlled parameter changes in the wheel's rotational speed, axial traversal rate, and contact pressure to achieve effective residue removal. By optimizing these parameters, the system removes material residues thoroughly while maintaining the casing material's integrity, ensuring the core remains reusable.
Solution Approach 2:
The patent replaces aggressive manual knife cleaning with a controlled automated wheel system that uses distributed friction and abrasion. This substitution achieves effective residue removal through controlled mechanical action rather than aggressive cutting, preserving the casing material and enabling core reuse.
