Paper Towel Cabinet Support Bar for Controlled Single-Towel Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paper towel dispensers suffer from bloating issues, leading to wastage and tearing of paper towels, especially when the stack is high or low, and aesthetics are compromised due to improper opening sizes and friction, which is exacerbated with recycled towels or wet hands.
Innovation Solution
A paper towel cabinet with a dispenser module featuring a bar extending between the edges of the opening, which supports the stack and reduces friction, preventing bloating and tearing by dividing the opening into smaller sections for controlled dispensing, and optionally using a weight to maintain orientation when the stack is depleted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large opening is provided in the cabinet to accommodate various fold configurations and sizes of paper towels, then the dispenser can accommodate various paper towel sizes and fold configurations, but the opening causes bloating of paper towels and allows multiple towels to be pulled out at once leading to wastage
Solution Approach 1:
The opening is divided into multiple smaller openings by providing partitions that extend from the bottom of the cabinet towards the front surface. Each partition creates a separate compartment for individual paper towels, preventing them from bunching together and being pulled out in clusters. This segmentation maintains the ability to accommodate various paper towel sizes while preventing wastage.
2Quantity of substance
If the stack of paper towels is high in the cabinet, then the dispenser can hold sufficient supply, but the weight of the stack causes bloating at the opening and friction that leads to tearing when pulling towels
Solution Approach 1:
By dividing the large opening into multiple smaller openings using partitions, each paper towel in the high stack has its own dedicated exit path. This reduces the friction and pressure concentration on individual towels, preventing tearing even when the stack is high and heavy.
Solution Approach 2:
The partitions create localized channels that guide each paper towel individually through the opening. This localizes the interaction between paper towels and the opening structure, reducing the cumulative friction effect that causes tearing in high stacks.
3Ease of operation
If the opening is large to allow manual pulling of paper towels, then ease of operation is improved, but the bottom opening does not correspond with the size of paper towels causing bloating and tearing
Solution Approach 1:
The opening is segmented into multiple smaller openings that better match the dimensions of individual paper towels. Each smaller opening corresponds more precisely to the size of a single towel, preventing bloating while still allowing easy manual pulling through the divided openings.

AI summary
A paper towel cabinet includes an enclosure and an opening that includes first edge a second edge. The cabinet further includes a dispenser module configured to be housed in the enclosure. The dispenser module includes a pair of generally parallel side walls defining a channel having a dispensing end, and a bar extending between the side walls proximate to the dispensing end. When the dispenser module is disposed in the enclosure with the dispensing end disposed at the opening, the bar extends along the opening between the first edge and the second edge of the opening. When a stack of paper towels is placed in the channel, the bar is disposed between a stack of paper towels and the opening. The paper towel cabinet may also include a bar extending along the opening between the first edge and the second edge without having a dispenser module. The bar may be formed at any one of the first edge or second edge of the opening by an inwardly curved surface formed by any one of the first edge and the second edge.
