Paper roll cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper roll dispensers lack protective covers, exposing toilet paper to soiling and airborne germs, and often fail to accommodate various configurations, making it difficult to tear paper with one hand and preventing excess paper from rolling off.
Innovation Solution
A universal paper roll cover with adjustable side walls and a unitary design that fits both wall-mounted and standalone dispensers, featuring apertures for pegs to secure the cover in place, a horizontal lip for easy paper cutting, and optional peg accessories for additional items like spare rolls or sanitizing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional paper roll dispenser without cover is used, then the dispenser structure is simple and easy to manufacture, but the paper is exposed to soiling and airborne germs
Solution Approach 1:
The cover is designed to fit over the existing paper roll and dispenser components, with the cover member enclosing the paper roll while allowing the spindle and basic dispenser structure to remain underneath. This nesting approach protects the paper without requiring complete redesign of the dispenser system.
Solution Approach 2:
The cover member is constructed as a thin-walled structure that provides protective enclosure while maintaining flexibility for installation and removal. The cover acts as a protective shell that can be easily fitted over the paper roll assembly.
2Adaptability or versatility
If a fixed paper roll cover design is used, then the manufacturing process is simple, but the cover fails to accommodate various dispenser configurations
Solution Approach 1:
The side walls are designed with adjustable positioning capabilities, allowing them to be moved or repositioned to accommodate different dispenser widths and configurations. This dynamic adjustment feature enables a single cover design to fit multiple dispenser types.
Solution Approach 2:
The cover is divided into separate components including the cover member and adjustable side walls that can be independently positioned or removed. This segmentation allows flexibility in adapting the cover to different dispenser configurations while maintaining manufacturing simplicity.
3Ease of operation
If no cover is used on the paper roll, then the dispenser structure remains simple, but excess paper rolls off and cannot be easily torn with one hand
Solution Approach 1:
The cover includes a pre-formed aperture or opening positioned to allow easy access and tearing of paper with one hand. This preliminary design feature anticipates the user's need for convenient paper retrieval without requiring additional tools or actions.
Solution Approach 2:
The cover acts as an intermediary structure that provides support and control over paper dispensing, preventing excess paper from rolling off while maintaining easy access through strategically positioned apertures and openings.

AI summary
A paper roll cover includes a cover member, a left side wall having a plurality of apertures peripherally around a central large aperture, a right side wall having a plurality of apertures peripherally around a central large aperture, and where the left side wall is arranged and configured to reside on a left side of the cover member and the right side wall is arranged and configured to reside a right side of the cover member. In some embodiments, the plurality of apertures in the right side wall or the left side wall are configured to fit pegs to adjust the paper cover roll to brackets mounted on a wall and alternatively to a stand alone paper roll stand.
