Plastic Bag Dispenser Pipe With Distal Openings for Selective Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic bag dispensers are not designed to store and support individually folded plastic bags with a front opening spanning the length of a pipe member, allowing for easy retrieval through distal openings, which is a feature lacking in prior art.
Innovation Solution
A wall bracket with a laterally oriented pipe member featuring a front opening that spans its length, includes distal openings for extending folded plastic bags, and is secured to a planar surface for independent removal of each bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional dispenser design is used, then the structure is simple, but it cannot store and support individually folded plastic bags with easy retrieval
Solution Approach 1:
The dispenser is segmented into distinct functional components: a support structure with multiple pipes, each pipe acting as an independent storage unit for folded bags. The pipes are arranged vertically with distal openings at different heights, allowing selective access to individual bags without disturbing others.
Solution Approach 2:
The invention transitions from horizontal roll-based dispensing to vertical pipe-based storage. Bags are folded and inserted vertically into pipes, utilizing the vertical dimension for storage capacity while maintaining easy horizontal retrieval through the front opening.
2Ease of operation
If a roll-based dispenser is used, then the structure is simple, but individual bag retrieval is not possible
Solution Approach 1:
The single roll structure is replaced with multiple separate pipes, each capable of holding individual folded bags. This segmentation allows users to retrieve any bag from any pipe independently, eliminating the need to unwind through entire rolls.
Solution Approach 2:
The pipes serve as intermediary structures between the wall mounting and the plastic bags. Each pipe provides a dedicated channel that guides and supports individual folded bags, facilitating easy insertion and retrieval while maintaining organizational structure.
3Ease of operation
If the front opening is wide, then bag insertion is easy, but unintentional disengagement occurs
Solution Approach 1:
The front opening has non-uniform dimensions: it is sufficiently wide at the entry point to accommodate folded bags easily, but tapers or narrows toward the distal end to provide mechanical retention. This local variation in opening size allows both easy insertion and secure holding.
Solution Approach 2:
The pipes feature curved or rounded contours rather than sharp angular transitions. The curved geometry of the front opening and internal pipe structure guides bags smoothly during insertion while the curvature at the distal end creates a natural retention point that prevents accidental disengagement.
4Ease of operation
If distal openings are not provided, then the structure is simpler, but bag ends cannot extend freely
Solution Approach 1:
The pipe structure is segmented with distinct openings: a front opening for bag insertion and distal openings at the ends for bag extension. This segmentation of opening functions allows bags to be inserted through the front while their ends extend freely through the distal openings, facilitating easy access and dispensing.

AI summary
The plastic bag dispenser pipe is constructed of a wall bracket from which a pipe member is rigidly affixed. The pipe member extends laterally an undefined length, and is further characterized with a front opening that spans along the length. The pipe member includes distal openings, which enable a plurality of individually folded plastic bags to extend at both distal openings. Each individually folded plastic bag is individually removed from the plastic bag dispenser pipe as needed. The wall bracket includes mounting surfaces that enable the plastic bag dispenser pipe to be secured to a generally planar surface.
