Adjustable Roll Support Dispenser for Varying Sheet Product Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for rolled sheet materials are limited in accommodating products with varying widths and core diameters, requiring multiple dispensers to handle different sizes, which increases costs and manufacturing time.
Innovation Solution
A dispenser design featuring a back frame assembly with adjustable mounting tracks and roll support members, including connection hubs with multiple diameters and spring-loaded hinges, allowing for flexible positioning and support of rolls with varying widths and core diameters within the same dispenser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dispenser is designed to accommodate a single product width or limited width range, then the dispenser structure is simple and manufacturing cost is low, but multiple dispensers are required to accommodate various product widths
Solution Approach 1:
The roll support member is designed to be adjustable along the mounting track, allowing dynamic repositioning to accommodate different roll widths. The support member can be moved to different positions on the track and secured at appropriate locations, enabling the same dispenser to handle various product widths without structural changes
Solution Approach 2:
The mounting track is divided into multiple positioning locations or zones along its length, allowing the roll support member to be segmented and positioned at different intervals. This segmentation enables flexible accommodation of different roll widths while maintaining a simple overall track structure
2Adaptability or versatility
If connection hubs with multiple diameters are used to support rolls with varying core diameters, then adaptability to different core diameters is improved, but manufacturing complexity increases
Solution Approach 1:
The connection hub incorporates multiple diameters at different local positions or sections, with each diameter optimized for specific core diameter ranges. This local differentiation allows the hub to accommodate various roll sizes while maintaining a relatively simple overall manufacturing process through modular or staged production techniques
3Adaptability or versatility
If adjustable mounting tracks and roll support members are implemented, then the dispenser can handle varying product dimensions, but the device complexity and manufacturing cost increase
Solution Approach 1:
The mounting track and roll support member combination serves multiple functions: it provides structural support, enables width adjustment, and accommodates different core diameters through the connection hub. This multi-functionality reduces the need for separate adjustment mechanisms, thereby maintaining manufacturing efficiency while achieving versatility
