Vertical Core Slot Bag Dispenser for Secure Roll Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag dispensing systems for roll-mounted bags fail to securely retain the bag roll, are not adaptable to various mounting systems, do not provide a visual indication for refilling, and are not durable, inexpensive, or easy to clean.
Innovation Solution
A vertical core slot dispenser system with angled platforms, a core pin, guide slots, and optional features like notches, guide rails, front and rear constraints, bag stream guides, and a security link to prevent roll loss, allowing for secure bag retention and adaptable mounting on different surfaces, with a design that facilitates easy cleaning and visual refilling indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing bag dispensing systems use simple mounting structures, then device complexity is reduced, but the bag roll cannot be securely retained and may accidentally leave the dispenser
Solution Approach 1:
The mounting structure is divided into separate functional components: a core pin for supporting the bag roll, guide slots for constraining roll movement, and a mounting bracket for attachment. This segmentation allows each component to perform its specific function while keeping the overall structure relatively simple.
Solution Approach 2:
The core pin is inserted through the hollow central core of the bag roll, creating a nested configuration where the pin is contained within the roll's core. This nesting provides secure retention without requiring complex external clamping mechanisms.
2Adaptability or versatility
If the dispenser is designed for specific mounting surfaces only, then manufacturing is simplified, but adaptability to various mounting systems is reduced
Solution Approach 1:
The mounting bracket is designed with multiple mounting options, allowing it to be attached to horizontal surfaces, vertical surfaces, or angled surfaces. This universal design enables the same dispenser to be mounted in various orientations and locations without requiring different dispenser models.
Solution Approach 2:
The mounting system allows for adjustable positioning and orientation of the dispenser. The bracket can be mounted at different angles and positions, providing dynamic adaptability to various installation environments while using the same basic dispenser structure.
3Difficulty of detecting and measuring
If the dispenser lacks visual refilling indication, then device complexity is reduced, but the ability to detect when refilling is needed is impaired
Solution Approach 1:
The dispenser incorporates visual indicators that change appearance based on the bag roll status. When the bag roll is full or properly installed, the indicator shows one state; when the roll is depleted or needs refilling, the indicator changes color or appearance to alert the user.
4Reliability
If the dispenser structure is complex, then bag roll retention is improved, but ease of cleaning is reduced
Solution Approach 1:
The core pin and guide slots are designed as separate, removable components that can be easily taken out for cleaning. This extraction of key retention components allows users to access and clean areas that would otherwise be difficult to reach in a fully integrated structure.
Solution Approach 2:
The dispenser utilizes smooth, continuous surfaces and thin-walled structures that are easy to wipe down and clean. The mounting bracket and dispenser housing are designed with minimal crevices and smooth transitions, allowing for easy cleaning while maintaining structural integrity for secure roll retention.

AI summary
A vertical core slot dispenser supports a roll of film bags wound on a hollow central core. An adapter for a bin provides mounting for at least one of the dispensers. An optional bracket has fixtures to connect lower portions of the platforms to a mounting system. A core pin has first and second ends, fits slidably within the central core and has at least one notch that extends across one of the ends. First and second guide slots are sized, shaped and located to fit slidably about the first and second ends of the core pin. At least one guide rail is located between outer edges of the guide slots. The rail is sized and shaped to slidably engage and retain the at least one notch in the core pin. At least one bag stream guide, pair of side constraints and snagging hook are attached to the bag dispenser.
