Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary tissue product rolls face challenges in achieving diameters greater than 6.5 inches due to stability issues and rotational momentum problems, with existing solutions failing to maintain stability and control rotation effectively.
Innovation Solution
Development of sanitary tissue product rolls with diameters greater than 8.25 inches, featuring Moment of Inertia values over 1.50 g*m2 and Roll Density values less than 2.50 g/cm3, along with a Core Kinetic Coefficient of Friction between 0.10 and 0.50, to enhance stability and control rotational momentum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the diameter of sanitary tissue product rolls is increased to exceed 6.5 inches, then the roll capacity and utility are improved, but the roll stability and rotational control deteriorate
Solution Approach 1:
The patent applies parameter changes by optimizing the Moment of Inertia to greater than 1.50 g*m2 and Roll Density to less than 2.50 g/cm3. These parameter adjustments allow larger diameter rolls to maintain stability by distributing mass appropriately, resolving the contradiction between increased roll capacity and maintained stability.
2Volume of moving object
If the diameter of sanitary tissue product rolls is increased beyond 6.5 inches, then the storage efficiency is improved, but the rotational momentum control becomes problematic
Solution Approach 1:
The patent utilizes parameter changes by specifying Moment of Inertia values greater than 1.50 g*m2, which directly influence rotational momentum characteristics. This allows larger rolls with better storage efficiency to maintain manageable rotational control during dispensing operations.
3Adaptability or versatility
If existing toilet tissue holders are used with rolls greater than 6.5 inches in diameter, then the adapter mechanism provides temporary compatibility, but the holder becomes problematic or worthless
Solution Approach 1:
The patent inverts the traditional approach by designing rolls that naturally fit standard holders without requiring adapters. By optimizing roll dimensions and physical properties, the invention makes the roll itself adaptable to existing holders, eliminating the need for unreliable adapter mechanisms and improving overall system reliability.
