Protective Towel Roll Wrapper for Clean Outdoor Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent towel containers are prone to contamination and degradation when exposed to inclement weather or dirty environments, leading to ineffective towel usage and inconvenience in maintaining a clean storage supply for replacement rolls.
Innovation Solution
A portable, water-resistant cylindrical towel roll product wrapped in a flexible, protective wrapper with a removable cover and a rigid disc for axial support, allowing easy access to individual towels without requiring the roll to be placed in a container, and providing axial stiffness to prevent distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If towels are stored in a cardboard box dispenser, then towels can be easily accessed through an opening, but the box becomes water or oil soaked when exposed to the elements, resulting in towel contamination
Solution Approach 1:
The patent applies a flexible waterproof membrane (such as vinyl or plastic) to line the interior of the cardboard box dispenser. This thin film barrier prevents water and oil from penetrating the cardboard structure while maintaining the box's shape and functionality. The membrane allows towels to be accessed through the opening while protecting them from contamination by external liquids.
Solution Approach 2:
The patent introduces a waterproof membrane as an intermediary layer between the cardboard box and the towels. This intermediate barrier protects the towels from direct contact with water or oil that may contact the box exterior, while still allowing the dispensing function to operate normally through the top opening.
2Reliability
If replacement towel rolls are stored in containers to protect them, then towels are protected from the elements, but it requires maintaining a clean storage space and inventory management
Solution Approach 1:
The patent enables the towel dispenser to be self-servicing by allowing users to simply insert new towel rolls into the protected box structure without requiring a separate clean storage space. The waterproof box itself serves as both protection and storage, eliminating the need for additional inventory management infrastructure.
Solution Approach 2:
The waterproof box dispenser serves multiple functions simultaneously: it protects towels from environmental contaminants, provides a storage space for replacement rolls, and enables easy dispensing. This multi-functionality eliminates the need for separate clean storage spaces and simplifies the overall system.
3Reliability
If a rigid container is used to protect towel rolls, then towels are protected from contamination, but the container becomes heavy and less portable
Solution Approach 1:
The patent employs a composite structure combining cardboard (for structural shape and rigidity) with a waterproof membrane (for contamination protection). This composite approach provides adequate protection against water and oil while maintaining low weight and portability, avoiding the need for heavy rigid plastic or metal containers.
Solution Approach 2:
The patent uses a flexible waterproof membrane instead of rigid protective materials. This thin film provides effective contamination protection while adding minimal weight, maintaining the portability and mobility of the dispenser system.

AI summary
A generally cylindrical towel roll product comprises an absorbent towel roll having an upright axis, and a flexible, water resistant, protective wrapper engaging the circumferential surface of the towel roll and of sufficient strength to restrain significant diametric expansion of the towel roll when the roll is subjected to an axial load and to increase axial stiffness of the product. The wrapper includes top and bottom portions that encase the top and bottom surfaces of the roll, respectively, the top wrapper portion having an opening providing axial access to the towel roll and through which individual towels can be drawn axially from the interior of the towel roll. A removable and replaceable soil and water-resistant cover protectively covers the wrapper opening, and a rigid disc may be provided between the top surface of the towel roll and the top portion of the wrapper, the disc extending radially to the periphery of the upper surface of the roll.
