Paper Roll Dispenser Threading Openings for Easier Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for roll-based absorbent paper materials face difficulties in easy refilling due to the restricted dispensing opening, which makes threading a new roll's web material challenging and time-consuming, especially when the opening is designed to be small for protection and automatic sheet-by-sheet dispensing.
Innovation Solution
The dispenser features a dual-threading opening system where the first and second threading openings are partly overlapping to form the dispensing opening, allowing a two-step threading process with larger opening sizes for easier access, facilitating the protrusion of a tail for user handling and enabling easy refilling without manual manipulation through a small dispensing opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dispensing opening is made small to protect the roll and enable automatic sheet-by-sheet dispensing, then the roll protection and automatic dispensing functionality are improved, but the threading process becomes difficult and time-consuming
Solution Approach 1:
The dispensing opening is divided into two separate threading openings: a first threading opening in the inner lid and a second threading opening in the outer lid. This segmentation allows the threading process to be split into two easier steps, where each opening can be larger and more accessible, while the final assembled dispensing opening remains small for protection and automatic dispensing functionality.
2Object-affected harmful factors
If the dispensing opening is made small to protect the roll, then the roll protection is improved, but the threading process becomes time-consuming
Solution Approach 1:
The threading process is segmented into two separate operations through two distinct threading openings. The first threading opening allows initial threading of the web material tail through the inner lid, and the second threading opening allows final threading through the outer lid. This segmentation reduces the complexity and time required for threading while maintaining the small final dispensing opening for roll protection.
3Adaptability or versatility
If the dispensing opening is restricted to hinder access to web material, then the automatic dispensing functionality is improved, but the refilling process becomes difficult
Solution Approach 1:
The restricted dispensing opening is segmented into two larger threading openings located in separate lids. This allows the refilling process to be simplified as users can thread the web material through the larger first threading opening in the inner lid, then complete the threading through the second threading opening in the outer lid, making refilling easier while maintaining the restricted final dispensing opening for automatic dispensing functionality.
Solution Approach 2:
The two threading openings act as intermediaries that facilitate the refilling process. Instead of directly threading through the small restricted dispensing opening, the system provides two larger intermediate threading openings that make the refilling process easier, while still achieving the same functional outcome of having the web material properly threaded through the restricted dispensing opening.

AI summary
A dispenser for a roll of rolled up absorbent paper web material, the dispenser, in a closed state, including an outer casing enclosing a roll compartment for housing a roll, and a dispensing opening extending from the roll compartment to the outside of the outer casing along a dispensing axis of the dispenser, the outer casing including an outer lid assuming a closed position when the dispenser is in the closed state. The dispenser further including an inner lid, which, in the closed state of the dispenser, is arranged between the roll compartment and the outer lid, wherein the inner lid defines a first threading opening through the inner lid along the dispensing axis, the first threading opening including a first dispensing opening portion; and the outer lid defines a second threading opening through the outer lid along the dispensing axis.
