Stretchable bedding components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bedding components, such as fitted bed sheets, are not easily adaptable to mattresses of varying sizes and depths, leading to inefficiencies in fabric consumption and fit issues.
Innovation Solution
Development of stretchable bedding components, particularly fitted bed sheets, using a blend of cotton and spandex or other elastic materials, with elastic bands and biocomponent yarns, allowing for reconfiguration between a retracted and expanded state to accommodate different mattress sizes and depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fitted sheets are sized to match specific mattress dimensions, then they provide a proper fit for that mattress size, but they cannot accommodate mattresses of varying sizes and depths
Solution Approach 1:
The fitted sheet incorporates elastic materials (spandex blend 5-30%) in the fabric construction, allowing the sheet to dynamically stretch and conform to different mattress sizes and depths. This dynamic property enables a single sheet design to adapt to various mattress dimensions while maintaining snug fit precision through the elastic recovery of the material.
Solution Approach 2:
The invention changes the physical parameter of the fabric by using stretchable materials with elastic properties. The spandex blend allows the sheet to change its dimensional parameters (length, width, depth accommodation) while maintaining fit quality, resolving the contradiction between adaptability and fit precision.
2Adaptability or versatility
If fitted sheets are made with extra fabric to accommodate larger mattresses, then they can fit bigger mattresses, but fabric consumption increases
Solution Approach 1:
By using elastic stretchable fabric, the sheet can expand to cover larger mattresses without requiring proportionally more fabric. The dynamic stretching capability allows one sheet to serve multiple mattress sizes, significantly reducing fabric consumption while maintaining adaptability across different bed sizes.
Solution Approach 2:
The stretchable fitted sheet is designed as a universal product that can fit multiple mattress sizes (twin, full, queen, king, California king) with a single design. This multi-functionality eliminates the need to produce separate sheets for each size, reducing overall fabric consumption while maintaining versatility.
3Adaptability or versatility
If fitted sheets use elastic materials to stretch and fit different mattress depths, then they accommodate varying depths, but the fabric becomes more complex
Solution Approach 1:
The invention uses composite fabric materials combining cotton (or other natural fibers) with spandex elastic fibers. This composite structure provides both the comfort properties of natural fibers and the stretch/elastic properties needed for depth accommodation. The complexity is managed through standard textile manufacturing processes for blended fabrics.
Solution Approach 2:
The fabric's elastic parameters are optimized to provide sufficient stretch for depth accommodation (5-30% elongation) while maintaining manageable complexity through controlled material composition and standard textile construction methods.

AI summary
Stretchable bedding components reconfigurable between a neutral or retracted configuration and an expanded configuration. In example embodiments, fabric is cut and sewn to form one or more bedding components with at least some dimensions being about 5%-30% less than those of conventional or traditional bedding components. In example embodiments, the length and/or width of the bedding component is expandable between about 5%-30%. In example embodiments, the stretchable bedding components include a biocomponent yarn having a helical structure that imparts elasticity therein so as to permit stretching of the one or more bedding components.
