Article Advancer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for articles like disposable gloves often result in unnecessary waste, especially when containers are partially full, due to reduced friction between contents and the container walls, leading to accidental dispensing of extra items that may become contaminated.
Innovation Solution
An article advancer assembly with an arcuate body and side legs that biases contents towards the dispensing opening, providing increased friction and reducing waste by moving from a compressed to a fully dispensed configuration, utilizing materials like acrylonitrile butadiene styrene or polyoxymethylene, and optionally including a platform to support the contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If articles are stacked or compressed together to maximize container space, then space utilization is improved, but friction between contents and container walls decreases leading to accidental dispensing of extra items
Solution Approach 1:
An article advancer mechanism is introduced as an intermediary component between the stacked articles and the dispensing opening. This advancer includes a biasing structure that applies force to push articles toward the dispensing opening, compensating for the reduced friction caused by compacted stacking. The advancer acts as a mediator that ensures controlled dispensing while maintaining high space utilization.
Solution Approach 2:
The friction parameter is actively modified by introducing the article advancer mechanism. Instead of relying on passive friction from compacted articles, the system changes the friction parameter by adding an active force through the biasing structure of the advancer, which compensates for the reduced natural friction and prevents accidental dispensing.
2Ease of operation
If container becomes less full during dispensing, then accessibility to articles is improved, but friction between contents and container walls decreases causing extra articles to be dispensed
Solution Approach 1:
The article advancer serves as a mediator that becomes increasingly important as the container empties. The biasing structure continuously applies force to maintain friction compensation, ensuring that even when the container is partially full and articles are more accessible, accidental dispensing is prevented through the advancer's active force application.
Solution Approach 2:
The article advancer provides continuous useful action throughout the dispensing process. The biasing structure maintains constant force application from the initial full container state through to the empty state, ensuring continuous friction compensation and preventing accidental dispensing at any stage of container depletion.
3Productivity
If multiple gloves are accidentally dispensed, then dispensing speed is improved, but contamination risk increases requiring disposal of extra items
Solution Approach 1:
The article advancer acts as a mediator between the bulk storage and the dispensing opening, providing controlled release of articles. This intermediary mechanism ensures that only the required number of articles are dispensed at any time, preventing the simultaneous dispensing of multiple items that could lead to contamination and waste.
4Volume of stationary object
If clumps of gloves become stuck together near the end of the container, then space utilization is improved, but dispensing accuracy decreases causing significantly more gloves to be dispensed
Solution Approach 1:
The article advancer mechanism serves as an intermediary that breaks up and separates clumped articles near the dispensing opening. The biasing structure applies force that distributes articles evenly, preventing clumps from being dispensed together and maintaining high dispensing accuracy even when space utilization is maximized through compact stacking.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The article advancer assembly significantly reduces waste by ensuring only the needed number of items are dispensed, maintaining the integrity and reducing contamination risks, with potential waste reduction of up to 40% compared to conventional systems.
Implementation Method 1
The article advancer is movable between a compressed configuration and a fully dispensed configuration. At least one of the arcuate body, the at least one first side leg, and the at least one second side leg providing a biasing force from the compressed configuration to the fully dispensed configuration.
Implementation Method 2
This can, in some forms, provide extra friction within the container and/or at the dispensing opening to decrease extra contents from being dispensed and thus decrease waste.
