Gown Dispenser System with Pull Tab Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical settings, there is a need for a quick and practical solution to allow medical staff to don hospital gowns efficiently and hygienically, as existing methods often require manual retrieval from a stack, which can be time-consuming and may lead to contamination.
Innovation Solution
A gown dispenser system comprising a stack of folded gowns with a pull tab on each, where the back region of each gown faces up, allowing for easy removal and exposure of the next gown, and an enclosure with a perforated opening for user access, enabling quick and sanitary gown distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gowns are stored in a stack without a dispenser system, then storage is simple, but retrieval is time-consuming and may lead to contamination
Solution Approach 1:
The gown stack is segmented into individual units with pull tabs, allowing one-at-a-time retrieval. Each gown is separated by its pull tab that engages with the dispenser mechanism, enabling quick extraction of single gowns without handling the entire stack, thus improving retrieval speed while maintaining organized storage
Solution Approach 2:
The dispenser system acts as an intermediary between the gown stack and the user. It provides a controlled interface where gowns are dispensed one at a time through a mechanism that engages with pull tabs, preventing direct contact with the entire stack and reducing contamination risk while simplifying the retrieval process
2Reliability
If manual retrieval from a stack is used, then device complexity is low, but hygiene and contamination control are compromised
Solution Approach 1:
The pull tab is extracted as a separate functional element attached to each gown. This tab extends beyond the gown body and engages with the dispenser mechanism, allowing the gown to be pulled out individually from the stack without exposing or contaminating other gowns in the stack, thus improving hygiene control
Solution Approach 2:
The dispenser mechanism serves as a hygienic intermediary that interfaces with the gown stack through pull tabs. It provides a barrier between the user's hands and the gown stack, with the mechanism controlling access and minimizing direct contact, thereby maintaining contamination control while enabling easy retrieval
3Ease of operation
If gowns are folded with back region facing up in a stack, then easy access to back region is achieved, but gown orientation and stacking complexity increases
Solution Approach 1:
Gowns are pre-folded with the back region facing up and pull tabs positioned to extend outward before being placed in the dispenser stack. This preliminary folding action ensures that when gowns are stacked, the pull tabs are automatically positioned for easy engagement with the dispenser mechanism, making retrieval intuitive without requiring additional manipulation
Solution Approach 2:
The folding process creates different orientations for different parts of the gown: the back region faces up for access, while the front region and sleeves are folded inward. This localized differentiation optimizes the exposed back region for easy grasping and pulling, while keeping the rest of the gown compact for efficient stacking

AI summary
A gown dispenser system has a plurality of gowns, each having a back region, the gowns folded and stacked back region facing up, such that, pulling on the back region of a gown on top of the stack removes that gown from the stack and exposes the back region of the next gown in the stack, an enclosure containing the stack of gowns, the enclosure having an opening exposing the back region of the gown at the top of the stack, enabling a user to grasp the exposed back region and pull the topmost gown from the enclosure, exposing the next gown in the stack. Gowns are drawn from the enclosure one-at-a-time, at need.
