Partial slipcover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nursing pillows often suffer from staining issues due to spills and milk residue, which are difficult to clean and can lead to permanent damage, necessitating a protective barrier that is removable and washable.
Innovation Solution
A partial slipcover made of composite textile with a hydrophobic wicking layer and an absorbent layer, attached using a fastener such as a hook and loop system, which acts as a protective barrier against stains and allows for easy removal and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a nursing pillow is used without a protective cover, then it provides comfort and support for feeding, but it is susceptible to staining and permanent damage from spills and milk residue
Solution Approach 1:
The protective system is segmented into a removable slipcover and the permanent nursing pillow. The slipcover comprises a front portion and a back portion that can be detached from the pillow, allowing the protective function to be separated from the structural support function. This resolves the contradiction by adding protective capability without permanently complicating the pillow's core structure.
Solution Approach 2:
The slipcover acts as an intermediary barrier between the nursing pillow and harmful substances (spills, milk residue). It provides the staining resistance function while allowing the pillow itself to remain simple and unchanged. The fastening system serves as an intermediary mechanism to attach and detach the protective layer without modifying the pillow's fundamental structure.
2Object-affected harmful factors
If a full protective cover is used on the nursing pillow, then it provides complete protection from stains, but it reduces breathability and comfort during feeding
Solution Approach 1:
The protective function is applied locally only where needed - the front portion of the slipcover protects the area most susceptible to spills during feeding, while the back portion provides minimal coverage. This localized approach maintains breathability and comfort in areas not requiring protection, resolving the contradiction between comprehensive protection and comfort.
Solution Approach 2:
Instead of providing complete full-coverage protection, the invention uses partial coverage with the front portion extending only to the necessary level for spill protection. This partial action approach achieves sufficient staining resistance while maintaining the breathability and comfort characteristics of the uncovered portions of the pillow.
3Object-affected harmful factors
If the protective cover is made completely waterproof, then it provides maximum stain protection, but it prevents the absorbent layer from functioning properly
Solution Approach 1:
The slipcover uses parameter changes in material properties - the front portion has water-resistant characteristics for stain protection, while the back portion uses an absorbent material with different parameters that allows moisture wicking. This variation in material parameters across different portions resolves the contradiction between maximum protection and absorbent functionality.
Solution Approach 2:
The slipcover is constructed as a composite structure with different materials serving different functions - a water-resistant front portion for stain protection and an absorbent back portion for moisture management. This composite approach allows each material to optimize its specific function without compromising the other, resolving the contradiction between protection and absorbency.
4Object-affected harmful factors
If the slipcover is tightly fitted to the nursing pillow, then it provides secure protection, but it is difficult to remove and replace for cleaning
Solution Approach 1:
The fastening system provides dynamic attachment - secure when fastened for protection during feeding, but easily releaseable when needed for cleaning. The adjustable nature of the fastening allows the slipcover to transition between a tightly fitted protective state and a removable state, resolving the contradiction between security and ease of removal.
Solution Approach 2:
The fastening system is designed to be easily operated by the user without requiring tools or complex mechanisms. The user can independently secure the slipcover tightly for protection and independently remove it for cleaning, making the system self-servicing and resolving the contradiction between secure fitting and easy removability.
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 slipcover effectively prevents staining by drawing liquids away from the surface, making it easy to clean and maintain the nursing pillow, ensuring longevity and hygiene.
Implementation Method 1
The first sheeting (111) is a wicking layer that forms the exterior surface (141) of the invention (100). The first sheeting (111) is an engineered textile formed from hydrophobic yarns. The purpose of the first sheeting (111) is to draw liquid away from the exterior surface (141) towards the second sheeting (112)
Implementation Method 2
The second sheeting (112) is an absorbent layer that is attached to the first sheeting (111) such that, as shown most clearly in FIG. 4, the first sheeting (111) and the second sheeting (112) from layers within the composite textile (101). The purpose of the second sheeting (112) is to act as a reservoir that draws moisture away from the exterior surface (141)
