Arcuate Folding Platform for Wrinkle-Reducing Fitted Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fitted bedding articles, such as fitted bed sheets with elastic bands, are difficult to fold due to the need for complex corner manipulation and flattening, often hindered by physical limitations and the size of the articles.
Innovation Solution
A folding apparatus with an arcuate surface and a holding member that allows corners of the bedding article to be positioned and secured, facilitating easier folding by guiding the corners along the surface and holding them in place for smoothing and final folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional folding techniques are used for fitted bedding articles, then the corners can be mated together, but the process requires difficult manipulation and additional smoothing to address wrinkles
Solution Approach 1:
The patent employs an arcuate surface on the folding platform that guides the corners of the fitted sheet through a curved path during folding. This curvature naturally facilitates the mating of corners together while maintaining tension on the elastic edges, reducing wrinkles and eliminating the need for additional smoothing operations.
Solution Approach 2:
The folding platform serves as an intermediary device between the operator and the fitted sheet. It provides a structured surface with arcuate guides that mediate the folding process, making corner manipulation easier and more consistent without requiring difficult manual dexterity.
2Adaptability or versatility
If fitted bedding articles are folded on a large flat surface, then corners can be manipulated, but the process is inhibited by physical limitations and size of the article
Solution Approach 1:
The folding platform is designed with arcuate surfaces and holding members that can accommodate fitted sheets of various sizes. The same structural features that work for smaller sheets also work for larger ones, providing universal applicability across different bedding article dimensions without requiring adjustment or modification.
Solution Approach 2:
The invention transitions from two-dimensional manipulation on a flat surface to three-dimensional folding guided by the arcuate surface. This dimensional approach allows corners to be brought together more easily by utilizing the vertical and radial dimensions of the curved platform, reducing the impact of article size and physical limitations.
3Manufacturing precision
If corners of fitted bedding articles are mated together, then folding can proceed, but additional smoothing and flattening is required to address wrinkles
Solution Approach 1:
The arcuate surface performs preliminary smoothing action during the corner-mating process itself. As corners are guided along the curved path and held by the holding members, the tension and guidance naturally flatten wrinkles before the final fold is completed, eliminating the need for separate smoothing operations.
Solution Approach 2:
The invention merges the corner-mating operation with the smoothing operation into a single integrated process. The same arcuate surface and holding members that facilitate corner alignment also simultaneously flatten wrinkles, combining multiple functions into one step and improving both precision and productivity.

AI summary
In one embodiment, an apparatus for folding a fitted bedding article includes a folding platform having an arcuate surface configured to receive a corner of the fitted bedding article. The apparatus also includes a holding member configured to releasably hold one or more portions of the fitted bedding article relative to the folding platform when at least one corner of the fitted bedding article is positioned about the arcuate surface. In another form, a method is directed to folding a fitted bedding article. However, other embodiments, forms and applications are also envisioned.
