Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolled product dispensers with braking mechanisms are complex, costly, and difficult to operate, requiring multiple moving parts and additional effort to control rotation and prevent uncontrolled rotation and unraveling of paper products, while also lacking versatility in orientation.
Innovation Solution
A rolled product dispenser featuring a rigid linear core with fixedly attached elastomeric fins that radially extend from a spindle to frictionally inhibit rotation, allowing for minimal loading time and adaptability to both vertical and horizontal surfaces without complex moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex braking mechanisms and rotation control devices are used, then rotation control effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential friction control function from complex braking mechanisms and rotation control devices, retaining only the necessary frictional elements (fins) while removing unnecessary moving parts and complex control systems. This achieves rotation control effectiveness with minimal device complexity.
Solution Approach 2:
The friction elements (fins) are designed to automatically engage with the rolled product tube and provide friction-based rotation control without requiring external control mechanisms, adjustment means, or additional moving parts. The system self-regulates rotation through the inherent friction between the fins and the tube.
2Reliability
If multiple moving parts and friction adjustment means are introduced, then rotation control capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes multiple moving parts and friction adjustment means from the design, retaining only the essential friction elements (fins) that provide rotation control capability. This extraction reduces manufacturing complexity and cost while maintaining the necessary rotation control function.
Solution Approach 2:
The design uses simple, inexpensive friction elements (fins) that can be easily manufactured and replaced if needed, rather than investing in complex, expensive mechanisms with multiple moving parts. The fins provide adequate rotation control at minimal manufacturing cost.
3Reliability
If complex braking mechanisms are used, then rotation control is improved, but ease of operation deteriorates
Solution Approach 1:
The friction elements (fins) automatically engage with the rolled product tube and provide rotation control without requiring user intervention, adjustment, or complex operation. The system self-regulates through friction, making operation simple and intuitive.
Solution Approach 2:
The patent removes complex braking mechanisms and rotation control devices that would require user interaction and adjustment, retaining only the simple friction elements that provide automatic, effortless rotation control.
4Measurement precision
If friction adjustment means are added, then rotation control precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the friction control function from complex adjustment mechanisms, using simple friction elements (fins) that provide adequate rotation control precision without requiring adjustment means or complex control systems.
Solution Approach 2:
The friction elements self-regulate rotation control through inherent friction between the fins and the rolled product tube, eliminating the need for adjustment means while maintaining appropriate rotation control precision.

AI summary
The present invention broadly comprises an apparatus for holding and dispensing rolled products comprising a rigid linear core with a spindle attached to the exterior of the rigid linear core with at least one fin fixedly attached to the spindle. The fins are attached parallel to the spindle, are constructed of an elastomeric material, and extend outwardly and radially from the spindle. Removably attached to the rigid linear core is a head. Also, a base is fixedly attached to the rigid linear core distal to the head. Alternatively, the base can be replaced by a bracket that is capable of being attached to vertical and horizontal surfaces.
