Baby Changing Pad Grip and Locator for Wet-Surface Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby changing pads slide on wet surfaces, leading to instability and potential accidents, as they lack effective engagement mechanisms for both wet and dry surfaces.
Innovation Solution
The baby changing pad apparatus incorporates a combination of a locator receiver and non-skid grip, featuring a quick connect system with hooks and loops, and a resilient base with a flexible cover, allowing for secure engagement on various surfaces, including wet and dry tables, using materials with high coefficients of friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional baby changing pad uses a smooth bottom surface, then it is easy to clean and simple in structure, but it slides on wet surfaces causing instability
Solution Approach 1:
The bottom surface is segmented into multiple functional zones: a non-skid grip portion made of high-friction material for wet surfaces, and a smooth portion for easy cleaning. This segmentation allows each zone to perform its specialized function without compromising the other.
Solution Approach 2:
Different regions of the bottom surface are assigned different material properties: the non-skid grip portion uses material with a high coefficient of friction (0.5 or higher) for enhanced grip on wet surfaces, while the smooth portion maintains low friction for easy cleaning. This local differentiation resolves the contradiction between stability and ease of cleaning.
2Reliability
If a baby changing pad uses a non-skid grip material with high friction, then it provides stable engagement on wet surfaces, but it may be difficult to clean
Solution Approach 1:
The bottom surface is divided into distinct cleaning zones: a smooth portion that is easy to clean and a non-skid grip portion that provides stable engagement. This segmentation allows the high-friction material to be applied only where needed for engagement, while maintaining large smooth areas for easy cleaning.
Solution Approach 2:
The patent applies different surface qualities to different locations: the non-skid grip portion has high friction (coefficient of 0.5 or higher) for reliable engagement on wet surfaces, while the smooth portion has low friction for easy cleaning. This local quality differentiation resolves the contradiction between engagement reliability and cleaning ease.
3Reliability
If a baby changing pad uses a quick connect system with locator and locator receiver, then it provides secure engagement to the surface, but it increases device complexity
Solution Approach 1:
The patent combines the quick connect system with the non-skid grip feature by integrating the locator receiver into the non-skid grip portion. This merging allows the connector mechanism and the non-skid grip to work together as a unified system, providing secure engagement without proportionally increasing complexity.
Solution Approach 2:
The locator receiver serves multiple functions: it provides the quick connect mechanism for secure engagement and simultaneously acts as part of the non-skid grip system. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while maintaining engagement security.
4Reliability
If a baby changing pad uses both locator receiver and non-skid grip combination, then it provides double surface engagement for enhanced stability, but it increases manufacturing complexity
Solution Approach 1:
The patent merges the locator receiver and non-skid grip into an integrated assembly where the locator receiver is positioned within or as part of the non-skid grip portion. This merging allows both features to be manufactured as a unified component or pre-assembled unit, reducing the complexity of final assembly while maintaining double surface engagement capability.
Solution Approach 2:
The non-skid grip portion serves dual functions: it provides friction-based stability on wet surfaces and simultaneously houses or works in conjunction with the locator receiver for mechanical engagement. This multi-functionality allows a single component to contribute to both engagement mechanisms, reducing the total number of parts and simplifying manufacturing.
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 solution provides double surface engagement, ensuring the baby changing pad remains stable during use, regardless of surface conditions, enhancing safety and usability while being simple to manufacture and use.
Implementation Method 1
A baby changing pad that sticks to a table that is wet, or moist, or has a wet spot, is desirable.
Implementation Method 2
A baby changing pad apparatus having a locator receiver, and specifically to a baby changing pad apparatus having both of a locator receiver and non-skid grip.

AI summary
A baby changing pad apparatus having a locator, locator receiver, and non-skid grip combination for engaging the baby changing pad apparatus to a first surface. The locator receiver includes a quick connect first portion engaged to the baby changing pad apparatus. The locator includes a quick connect second portion engagable between the quick connect first portion and first surface. The non-skid grip may engage the first surface with or without the locator engaged to the locator receiver.
