Disposable Over-the-Head Gown With Overlapped Side Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable over-the-head (OTH) full back isolation gowns with perforations pose a risk of contamination and are costly to manufacture due to their design, as they allow exposure to germs and infectious agents and complicate the donning and doffing process.
Innovation Solution
A disposable OTH full-back isolation gown with integral or attached side panels that overlap and are secured using various attaching means such as welding, adhesives, or fasteners, creating a seamless back coverage while allowing easy donning and doffing by minimizing attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If perforations are included to aid in gown removal, then ease of doffing is improved, but contamination risk increases and manufacturing complexity increases
Solution Approach 1:
The gown is divided into two separate panels (front panel and back panel) that are attached at the sides. This segmentation allows the panels to be easily separated during doffing by simply pulling them apart at the attachment points, eliminating the need for perforations while maintaining ease of removal.
Solution Approach 2:
The harmful feature (perforations) is completely removed from the design. Instead of including perforations that create contamination risk, the patent uses side panel attachments that can be easily detached without creating openings or exposure points for contaminants.
2Ease of operation
If perforations are included to aid in gown removal, then ease of doffing is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The gown structure is segmented into separate front and back panels attached at the sides, which simplifies the manufacturing process. Each panel can be manufactured independently and then attached using simple methods such as adhesive tapes or bonds, eliminating the need for complex perforation processes.
Solution Approach 2:
Instead of creating openings (perforations) in the gown material to facilitate removal, the patent inverts the approach by using attachable side panels that are connected along the edges. This inversion simplifies manufacturing as it eliminates the need for perforation machinery and processes.
3Object-affected harmful factors
If side panels are overlapped and attached, then full back coverage and contamination protection are improved, but device complexity increases
Solution Approach 1:
The front panel and back panel are merged into a single garment structure that provides full back coverage when worn. The panels overlap at the sides and are attached together, creating a unified gown structure that protects the wearer's back while maintaining simple donning and doffing procedures.
