Bag Dispenser with Universal Roll Mounting and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag dispensers are limited in accommodating different types of rolls and pose safety hazards due to the potential unintentional release of the entire roll, risking customer injury.
Innovation Solution
A universal bag dispenser design featuring a support structure, arms, and a pin system that allows secure mounting and dispensing of various roll sizes, with a locking mechanism to prevent accidental roll removal, ensuring safety and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bag dispensers are designed to hold rolls of bags, then they can dispense bags, but they are limited in accommodating different types of rolls and can allow unintentional removal of the entire roll
Solution Approach 1:
The bag dispenser is designed with a universal mounting structure that can accommodate different types and sizes of bag rolls. The arm can be positioned at multiple angles and the pin can be adjusted to fit various roll configurations, allowing the same dispenser to handle multiple roll types from different manufacturers while maintaining secure attachment through the locking mechanism
Solution Approach 2:
The locking mechanism includes a pin that extends through the arm and engages with the roll mounting structure to prevent unintentional removal of the roll. This preliminary anti-action counteracts the potential harmful effect of accidental roll detachment before it can occur, ensuring safety while allowing controlled dispensing operation
2Reliability
If a secure locking mechanism is added to prevent roll removal, then safety is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into simple, discrete components: a pin that extends through the arm, a mounting structure on the roll, and a locking engagement point. This segmentation allows the safety function to be achieved through basic mechanical elements rather than a complex integrated system, maintaining simplicity while ensuring reliability
Solution Approach 2:
The pin acts as an intermediary element between the arm and the roll mounting structure. It provides the locking function by physically connecting these two components, preventing roll removal without requiring complex mechanisms. The pin serves as a simple mediator that achieves safety through basic mechanical engagement

AI summary
Exemplary embodiments are related to a bag dispenser. The bag dispenser can include a support structure, a first arm, a second arm, and a pin. The support structure can have an elongated body. The first arm can be operatively coupled to, and can extending from, a first end of the support structure. The second arm can be operatively coupled to, and can extend from, a second end of the support structure. The pin can have a proximal end and a distal end. The proximal end of the pin can be secured to the first arm and can be configured to translate within a first bounded channel between a first opposing channel ends. The distal end of the pin is configured to be received by a second bounded channel and can be configured to translate within a second bounded channel between a second opposing channel ends.
