Toilet Paper Roll Width Reduction to Lower Consumption and Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The overconsumption of toilet paper leads to increased use of natural resources, energy consumption, and strain on municipal and septic systems, with consumers showing resistance to changing their consumption habits despite educational efforts.
Innovation Solution
A toilet paper roll with a reduced width, within a specific range, encourages consumers to use less paper by altering their usage patterns, either by reducing the length used or compensating with fewer sheets, while maintaining the length of the sheet, and can be supported by a cylindrical structure made of cardboard or recycled plastic, with optional scoring or perforations for easier tearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If toilet paper width is reduced to a specific range (2-3.6 inches), then toilet paper consumption is reduced, but consumer satisfaction may deteriorate due to altered usage patterns
Solution Approach 1:
The patent applies parameter changes by modifying the width of toilet paper sheets to a specific range (2-3.6 inches). This dimensional parameter change directly reduces the amount of paper consumed per use while maintaining functional effectiveness. The controlled width parameter ensures that consumers use less paper without completely altering their usage behavior, thus resolving the contradiction between reduced consumption and maintained ease of operation.
2Strength
If premium brands with increased fiber content are used, then product quality is improved, but resource consumption and waste generation increase
Solution Approach 1:
The patent resolves this contradiction by changing the width parameter rather than reducing fiber content. By controlling the dimensional parameter (width within 2-3.6 inches), the invention maintains product quality and strength while reducing the total quantity of fibers required per use. This approach allows premium brands to retain their quality characteristics while inherently reducing resource consumption through optimized dimensions.
3Ease of operation
If toilet paper is overused, then consumer satisfaction is maintained, but strain on municipal and septic systems increases
Solution Approach 1:
The patent addresses this contradiction by implementing parameter changes in sheet width (2-3.6 inches) that automatically reduce the volume of paper entering waste systems. This parameter optimization allows consumers to maintain their satisfaction with paper quality and performance while the reduced dimensional parameters inherently decrease the burden on municipal and septic infrastructure, eliminating the need for behavioral change education.

AI summary
A toilet paper roll includes toilet paper wrapped to define a central opening having an interior diameter. The toilet paper is scored to form sheets. Each sheet has a width in a range of 2 inches to 3.6 inches. A toilet paper roll adapter includes a first portion to engage an interior diameter of a roll of toilet paper roll and a second portion concentric with the first portion. The second portion has a radius greater than the interior diameter of the toilet paper roll and adapts the width of the toilet paper.
