Quick Release Medical Gown With Pull Cord Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical gowns require time-consuming and potentially straining manipulations for removal, especially for individuals with back, neck, or shoulder injuries, and pose a risk of contamination during the process.
Innovation Solution
A medical gown design featuring an open back with a secured belt tie that prevents contamination and allows easy closure, a quick-release strap through the collar for neck closure, and a pull cord mechanism that enables easy removal without reaching behind the neck, along with belt loops to keep the belt off the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional back-tie gown closure is used, then the gown can be securely closed, but the wearer must reach behind their neck and back which is time-consuming and difficult for persons with back, neck, or shoulder injuries
Solution Approach 1:
The gown closure system is segmented into multiple independent fastening points: snap closures at the neck, snap closures at the back, and belt loops at the waist. This segmentation allows the wearer to close the gown in stages from front to back, eliminating the need to reach behind the neck while maintaining secure closure.
Solution Approach 2:
The traditional sequence of closing a gown (starting from the back) is inverted. The gown is designed to be closed starting from the front neck area and progressing backward, with the final back closure being the easiest to reach. This reversal of the closing sequence eliminates the need to reach behind the neck during the closing process.
2Ease of operation
If traditional back-tie gown removal is used, then the gown can be removed, but the wearer must reach behind their neck and back which causes strain and potential contamination
Solution Approach 1:
The gown removal process is segmented into discrete steps corresponding to each fastening point. The wearer systematically unfastens snaps and unties belts in a predetermined sequence from front to back, eliminating the need to reach behind the neck. This segmented approach reduces strain on the back and neck while minimizing contamination risk by keeping hands away from the neck area.
Solution Approach 2:
The gown is designed with all fastening elements positioned and configured in advance to facilitate easy access during removal. Belt loops are positioned at the front and sides, and snap closures are arranged to be accessible from the front, allowing the wearer to prepare for removal without reaching behind the neck.
3Ease of operation
If an open back design is used, then the wearer can easily don the gown, but the belt may touch the ground causing contamination
Solution Approach 1:
The belt system is elevated from a single horizontal plane to a three-dimensional configuration using vertical and diagonal belt loops. The loops are positioned at different heights and angles, creating a suspended configuration that keeps the belt away from the ground while maintaining secure closure. This dimensional arrangement prevents ground contact while preserving easy donning.
4Strength
If the belt is tied at the back, then the gown is securely closed, but the wearer must reach behind their back which is difficult for persons with back, neck, or shoulder injuries
Solution Approach 1:
The belt closure function is segmented and redistributed to multiple locations: belt loops are positioned at the front waist, sides, and back. This segmentation allows the belt to be tied at accessible locations (front or sides) rather than requiring the wearer to reach behind the back, while maintaining secure closure through the distributed loop system.

AI summary
A quick release medical gown, which is formed with a pull cord on the front shoulder of gown, attached at one end to the outside of the gown, and run through the collar, where it is attached at the neckline closure on the gown. the gown closure is a quick release fastener, such as snaps or a hook-and-loop closure. The device is designed so that the cord on the front of the gown may be pulled, unfastening the neckline closure, and allowing the wearer to remove the gown with little to no need for assistance, or reaching behind themselves. This design allows for decreased risk of contamination for the wearer, and allows them increased independence in donning and doffing their gown.
