Coreless Paper Roll Dispenser With Conical Self-Centering Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coreless roll dispensing systems require additional plastic end pieces and grooved rollers, leading to increased manufacturing costs and waste, as well as complex processing facilities, to ensure compatibility and quality.
Innovation Solution
A dispensing system that uses a conical or frustoconical guiding and positioning element with a pivotally mounted cover, allowing the roller to be self-centered and captive without additional elements, facilitating easy installation and use while maintaining product quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional plastic end pieces and grooved rollers are used to ensure compatibility and quality, then the reliability of the dispensing system is improved, but the manufacturing cost and waste increase
Solution Approach 1:
The invention extracts and eliminates the additional plastic end pieces from the system by integrating the guiding and positioning functions directly into the cover structure through housings and conical elements, thereby reducing waste while maintaining compatibility
Solution Approach 2:
The invention merges the functions of the cover, guiding elements, and positioning mechanisms into a single integrated structure, eliminating the need for separate plastic end pieces and reducing manufacturing waste
2Reliability
If additional plastic end pieces and grooved rollers are used to ensure compatibility and quality, then the reliability of the dispensing system is improved, but the manufacturing cost increases
Solution Approach 1:
The invention removes the need for additional plastic end pieces and separate guiding components, reducing the number of parts to manufacture and thereby lowering manufacturing costs while maintaining system reliability
Solution Approach 2:
By combining multiple functions into the cover structure itself, the invention reduces the total number of components that need to be manufactured, assembled, and inventoried, thereby reducing manufacturing costs
3Reliability
If grooved rollers are used to ensure compatibility, then the reliability of the dispensing system is improved, but the device complexity increases
Solution Approach 1:
The invention extracts the guiding and positioning functions from complex grooved rollers and transfers them to simpler housing structures with conical elements, thereby reducing device complexity and processing requirements while maintaining compatibility
Solution Approach 2:
Instead of modifying the roller with grooves to achieve compatibility, the invention inverts the approach by providing guiding and positioning structures in the cover that work with the roller as-is, thereby simplifying the overall system
