Portable Changing Table Cover With Germ-Containment Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public restroom changing tables are often unsanitary, posing a risk of infection and illness to young children, as existing changing solutions fail to provide adequate protection and hygiene.
Innovation Solution
A changing table cover comprising a sheet with elastic corners, a pillow, and a bag made from sanitary materials, designed to fit standard changing tables, with features like zippers or hook and loop fasteners for closure, non-slip materials, and a mechanism to contain germs within the bag, ensuring full coverage and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a changing table cover is used to protect against germs, then hygiene is improved, but the device complexity increases due to multiple components (sheet, pillow, bag, fasteners)
Solution Approach 1:
The changing table cover is divided into distinct functional segments: a sheet portion for covering the table surface, a pillow portion for infant comfort, and a bag portion for storing soiled items. This segmentation allows each component to be optimized for its specific function while maintaining overall hygiene protection.
Solution Approach 2:
The pillow portion is nested within or adjacent to the bag portion, with the bag configured to receive and contain the pillow. This nesting arrangement consolidates multiple components into a compact integrated structure that provides comprehensive protection without excessive complexity.
2Object-affected harmful factors
If the changing table cover includes a bag for containing soiled items, then hygiene is improved, but the volume of the device increases
Solution Approach 1:
The pillow is positioned to fit within or alongside the bag, maximizing space utilization. The bag is configured with dimensions that accommodate the pillow while maintaining a compact overall profile that minimizes volume increase.
Solution Approach 2:
The bag is formed from a flexible material that can conform to the contents and fold efficiently. This flexible construction allows the bag to provide adequate containment volume while maintaining a compact form factor when not in use.
3Object-affected harmful factors
If the sheet is made large enough to cover the entire changing table, then hygiene is improved, but the area of material required increases
Solution Approach 1:
The sheet is constructed from flexible material that can drape and conform to the changing table surface, providing complete coverage with minimal material waste. The flexibility allows the sheet to adapt to the table contours rather than requiring excessive material for a rigid fit.
Solution Approach 2:
The sheet dimensions and shape are optimized to match the specific geometry of standard changing tables. By adjusting the parameters of the sheet (size, shape, flexibility), complete coverage is achieved with the minimum necessary material area.
4Reliability
If the changing table cover includes multiple fastening mechanisms (zippers, hook and loop fasteners), then reliability of closure is improved, but the ease of operation decreases
Solution Approach 1:
The cover is designed as a disposable or easily replaceable item, allowing simple fastening mechanisms to be used without requiring high durability. This approach prioritizes ease of operation while maintaining adequate closure reliability for the intended use lifecycle.
Solution Approach 2:
Different fastening mechanisms are strategically positioned at specific locations on the cover based on functional requirements. Hook and loop fasteners may be used at locations requiring quick adjustment, while zippers are placed where secure closure is critical, optimizing both reliability and ease of operation locally.
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 changing table cover provides a safe and hygienic environment for changing children by covering the entire table surface, preventing germ transfer to the child and other items, while being compact and portable for use in various settings.
Implementation Method 1
The sheet includes a plurality of corner portions, at least two of which include elastic material. The two corner portions including elastic material are configured to fit around two corners, respectively, of the changing table platform.
Implementation Method 2
The changing table cover further includes a non-slip material affixed to a bottom portion of the sheet.
