Stretch-Corner Bed Sheets for Variable Mattress Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed clothing systems fail to accommodate a wide range of mattress thicknesses and sizes, leading to issues such as tightness, tangling, and difficulty in fitting mattresses with unique designs or contours, including pillow tops and dynamic mattresses.
Innovation Solution
A bed clothing system featuring stretchable materials at strategic corners of both the bottom and top sheets, allowing for vertical alignment and expansion to adapt to various mattress thicknesses and sizes, ensuring a secure, comfortable fit and ample foot space, while preventing the top sheet from slipping or becoming tangled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bed clothing systems are used, then the structure is simple, but the system cannot accommodate a wide range of mattress thicknesses and sizes
Solution Approach 1:
The patent applies local quality by placing stretchable materials specifically at the corners of the bed sheets rather than making the entire sheet stretchable. This localized application of elastic properties allows the corners to adapt to mattress thickness variations while keeping the rest of the sheet structure simple and non-stretchable, thus achieving adaptability without excessive complexity.
Solution Approach 2:
The patent incorporates dynamic elements by using stretchable materials that can elastically deform to accommodate different mattress thicknesses. The stretchable corners can dynamically adjust their configuration based on the mattress depth, allowing the bed clothing system to adapt to various mattress sizes while maintaining a relatively simple overall structure.
2Adaptability or versatility
If stretchable materials are added to accommodate different mattress thicknesses, then adaptability improves, but the risk of tangling and slipping increases
Solution Approach 1:
The patent confines the stretchable material to specific corner regions rather than distributing it across the entire sheet. This localized placement allows the corners to provide adaptive fit while the larger portions of the sheets remain stable and non-stretchable, reducing the overall risk of tangling and slipping.
Solution Approach 2:
The bed sheet is segmented into stretchable corner portions and non-stretchable main body portions. This segmentation allows different regions to perform different functions: the stretchable corners adapt to mattress thickness while the non-stretchable portions maintain stability and prevent tangling.
3Adaptability or versatility
If stretchable materials are used at corners, then the system can adapt to various mattress thicknesses, but the appearance may be compromised due to visible elastic
Solution Approach 1:
The stretchable material is localized to the corner regions where it is less visually prominent. This allows the elastic components to be concealed within the corner constructions, maintaining a clean appearance from the main viewing areas of the bed sheets while still providing the necessary adaptability.

Function Achieved in This Case
The system provides a secure, comfortable, and adaptable fit for mattresses of different sizes and thicknesses, reducing the risk of tangling, maintaining a clean appearance by hiding elastic, and simplifying bed-making processes, even for dynamic mattresses.

AI summary
Disclosed is a bed clothing system that has a bottom sheet and top sheet attached together at the corners of the foot end of the bed clothing system. At the foot end of the bed clothing system on the corners, where the top and bottom sheets are attached, a stretchable piece of material is disposed in a vertical direction so that the bed sheet system is able to accommodate to any size and thickness of a mattress, while also remaining securely fixed on a mattress.
