Paper product dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing consumable product dispensers often require cumbersome core or center axis support for rolled paper products, limiting their versatility and ease of use, especially when dealing with varied core configurations and sizes.
Innovation Solution
A paper product dispenser featuring two parallel spindle arms that support and rotate rolled paper products along their periphery, allowing for easy loading and unwinding without core or tube support, combined with a cutting drum that rotates multiple times before cutting, driven by a drive belt and actuated by user action or motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If core or center axis support is used for rolled paper products, then the roll is securely supported, but the device complexity increases and versatility decreases when dealing with varied core configurations
Solution Approach 1:
The invention removes the traditional core or center axis support structure from the dispenser and replaces it with spindle arms that contact the roll periphery. This extraction of the core support mechanism eliminates the problem of incompatibility with varied core configurations while maintaining reliable roll support through peripheral contact points.
Solution Approach 2:
The spindle arms are designed to universally accommodate different roll configurations by contacting the periphery of the roll rather than requiring specific core features. This universal peripheral contact approach allows the same dispenser mechanism to reliably support rolls with various core sizes, shapes, and materials without modification.
2Manufacturing precision
If manual winding through multiple feed points is required, then cutting precision can be maintained, but user effort and operation complexity increase
Solution Approach 1:
The dispenser incorporates an auto-feed mechanism that automatically winds the paper roll through the cutting mechanism without requiring manual intervention. The system self-regulates the feeding process, maintaining consistent tension and alignment while eliminating the need for users to manually wind paper through multiple feed points, thus preserving cutting precision while dramatically improving ease of operation.
Solution Approach 2:
The auto-feed mechanism performs preliminary winding and positioning actions automatically before the cutting operation occurs. This preliminary automated preparation ensures the paper is properly aligned and tensioned in advance, maintaining cutting precision without requiring the user to perform manual winding operations.
3Productivity
If the cutting drum rotates only once before cutting, then the cutting speed is faster, but the paper feed control and cut quality may be compromised
Solution Approach 1:
The cutting drum is designed to rotate multiple times (e.g., twice) before performing the cut. This periodic rotation allows the paper to be fed through the cutting mechanism in controlled increments, ensuring proper alignment and tension maintenance. The multi-rotation approach balances cutting speed with feed control precision, preventing paper jams and ensuring clean cuts by allowing the system to complete full rotation cycles that maintain consistent paper flow.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy loading and consistent dispensing of paper products with varying core and tube configurations, reducing user effort and improving reliability by auto-feeding rolls and preventing simultaneous feeding of new and depleted rolls.
Implementation Method 1
A rotation of the cutting drum and rotation of at least one of the first and second spindles are driven by a drive belt
