Changing table cover
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 solutions like changing pads are not large enough to cover the table and do not effectively isolate germs from other items.
Innovation Solution
A changing table cover comprising a sheet with elastic corners, a pillow, and a bag made from sanitary materials, with a mechanism to prevent the exchange of liquids and gases, ensuring full coverage and portability, and designed to fit standard changing table platforms with non-slip features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a changing table cover is used to protect against germs, then sanitation is improved, but the device complexity increases due to multiple components (sheet, pillow, bag, fastening mechanisms)
Solution Approach 1:
The changing table cover is divided into distinct functional components: a sheet for covering the table surface, a pillow for infant comfort, and a bag for storing soiled items. Each component can be independently cleaned, replaced, or laundered, simplifying maintenance while maintaining comprehensive germ protection.
Solution Approach 2:
The pillow is positioned within the confines of the sheet, and the bag is attached to or nested within the sheet assembly. This nested arrangement consolidates multiple protective functions into a compact integrated unit that covers the changing table surface while containing storage and comfort elements.
2Area of stationary object
If the sheet is made large enough to fully cover the changing table, then coverage is improved, but the ease of operation deteriorates due to difficulty in folding and storing
Solution Approach 1:
The sheet incorporates elastic material at its corners, transforming it from a rigid static covering into a dynamic, adaptable component that can stretch and conform to the changing table surface. This elasticity enables the large sheet to be easily folded, compressed, and stored in the attached bag when not in use.
Solution Approach 2:
The sheet is constructed as a flexible thin film material that can be draped over the changing table surface to provide full coverage. Its flexibility allows it to be easily manipulated, folded, and stored in the compact bag configuration when removal is needed.
3Stability of the object's composition
If elastic material is added to the corners of the sheet, then the stability of the cover is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The elastic material is incorporated as discrete corner portions rather than throughout the entire sheet. This segmentation concentrates the stabilization function at the critical corner points where the sheet contacts the changing table, providing maximum stability with minimal additional manufacturing complexity.
4Object-affected harmful factors
If a bag with closure mechanism is attached to the sheet, then germ containment is improved, but the device complexity increases
Solution Approach 1:
The bag is attached to or integrated with the sheet, merging the storage function with the protective covering. This combination creates a unified assembly where the sheet provides germ barrier protection while the attached bag contains soiled items, eliminating the need for separate storage containers.
Solution Approach 2:
The sheet assembly serves multiple functions: it covers the changing table surface for germ protection, provides a surface for placing items, and includes an attached bag for storing soiled diapers and clothing. This multi-functionality consolidates several protective and storage operations into a single integrated device.
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 sanitary environment for changing children by fully covering the table, containing germs within the cover, and preventing their transfer to 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.
