Mattress cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mattress covers fail to snugly fit mattresses of varying thicknesses, lengths, and widths due to the lack of standardization in mattress sizes, leading to issues like bunching, slipping, and difficulty in securing the cover, making it impractical for manufacturers to maintain inventory for all size variations.
Innovation Solution
A mattress cover design featuring a rectangular piece of material with a top center portion, peripheral skirt, and corner panels, including elastic bands around the bottom periphery, allowing it to fit mattresses from 6 to 21 inches thick and 37 to 78 inches wide, with corner panels that can be triangular or isosceles right triangles, made from various fabrics, and manufactured from a single piece of material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mattress covers are configured for specific mattress thicknesses, then they fit snugly on mattresses of that thickness, but they cannot accommodate mattresses of varying thicknesses and slip off or bunch excessively
Solution Approach 1:
The mattress cover employs an elastic band at the bottom periphery that can dynamically adjust and conform to mattresses of varying thicknesses. This elastic component allows the cover to adapt its shape and tension based on the specific mattress dimensions, providing a secure fit across different thickness ranges without requiring multiple fixed designs.
Solution Approach 2:
The invention changes the physical parameter of the bottom edge by incorporating an elastic band that can stretch and compress. This allows the cover to accommodate a range of mattress thicknesses (6-21 inches) by adjusting the tension and position of the elastic band, transforming a static fit into a dynamically adjustable one.
2Adaptability or versatility
If deeper pockets are added to accommodate thicker mattresses, then the cover can fit thicker mattresses, but it becomes difficult to secure on thinner mattresses and harder to manufacture
Solution Approach 1:
The mattress cover is segmented into distinct functional zones: a top center portion for the mattress surface, a peripheral skirt portion with end and side panels, and corner panels. This segmentation allows each part to be optimized independently - the skirt provides depth accommodation while the corner panels and elastic band provide securing mechanisms, simplifying manufacturing compared to a fully deep-pocket design.
Solution Approach 2:
Different parts of the mattress cover have different qualities and functions. The top center portion is designed for coverage, the peripheral skirt for depth accommodation, and the corner panels with elastic bands for securing. This local differentiation allows the cover to handle varying mattress depths without requiring the entire structure to be overly complex or difficult to manufacture.
3Reliability
If elastic bands are added to secure the cover, then the cover stays in place better, but it becomes difficult to care for and expensive to manufacture
Solution Approach 1:
The elastic band functions as a flexible element that can be integrated into the fabric construction. By using a flexible elastic band rather than rigid fastening mechanisms, the design achieves secure attachment while maintaining ease of manufacture and care. The elastic band can be sewn into the fabric perimeter, creating a simple yet effective securing mechanism that does not complicate manufacturing or maintenance.
4Reliability
If corner panels are added to prevent slipping, then the cover secures better on thick mattresses, but the design becomes more complex and difficult to install
Solution Approach 1:
The corner panels are merged with the elastic band system rather than being separate components. The elastic band runs continuously around the bottom periphery and integrates with the corner panels, combining the securing function and the corner reinforcement into a single integrated system. This reduces the number of separate parts and simplifies installation while maintaining the anti-slip functionality.
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 mattress cover provides a snug, secure fit for both thin and thick mattresses of varying sizes, is easy to use and care for, and economical to manufacture, accommodating a wide range of mattress classifications without slipping or bunching.
Implementation Method 1
one or more elastic bands attached around a bottom periphery of an inside edge of the skirt portion and corner panels

AI summary
A mattress cover including a substantially rectangular piece of material including a top center portion for fitting upon a top surface of a mattress, and a peripheral skirt portion including two end panels and two side panels, wherein the respective end panels and side panels may be attached together at each corner for fitting over corresponding sides and ends of the mattress, corner panels attached to a bottom portion of each corner formed from the respective attached end panels and side panels, wherein the corner panels may be substantially parallel to the top center portion, and one or more elastic bands attached around a bottom periphery of an inside edge of the skirt portion and corner panels.
