Bed Sheet with Elastic Corner Strips to Prevent Slipping and Tearing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bed sheets often rip or tear due to stretching and wear, and they can slip off mattresses, especially with the use of plastic protectors, making the process of dressing a mattress time-consuming and labor-intensive, and prone to musculoskeletal disorders from prolonged leaning.

Innovation Solution

Incorporating elastic members into the top edge and corners of the bed sheet for flexibility and durability, along with parallel drawstrings for adjustable length and stitched corners for securement, which also includes side flaps and a slit for air escape to prevent slipping and tearing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional bed sheets are used, then they can cover the mattress, but they rip or tear due to stretching and wear from repeated tugging and pulling

Engineering Contradiction:

Improvedurability of bed sheetVSAvoidintegrity of bed sheet

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The bed sheet is divided into multiple panels (first panel, second panel, third panel, fourth panel) that can move independently relative to each other. This segmentation allows each panel to stretch and move without causing stress concentration that would lead to tearing, while the panels remain connected through their edges to maintain overall sheet integrity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If conventional bed sheets are used, then they can be placed on the mattress, but they slip off when users move on top of the bed sheet

Engineering Contradiction:

Improveease of bed makingVSAvoidstability of bed sheet position

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The bed sheet incorporates dynamic elements including elastic members in the corners that allow the sheet to stretch and adapt when users move on the bed. The multiple independent panels can shift and adjust dynamically to user movement while remaining secured to the mattress, preventing the sheet from slipping off during use.

Inventive Principle:

Principle #15Dynamics

3Productivity

If conventional bed sheets are used, then they can cover the mattress, but the process of dressing the mattress is time consuming and labor intensive

Engineering Contradiction:

Improveefficiency of bed makingVSAvoidtime required for bed making

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The bed sheet is pre-configured with multiple panels and elastic corner members in specific arrangements before use. This preliminary structuring allows the sheet to be quickly deployed onto the mattress without requiring complex manual adjustment during the bed-making process, significantly reducing the time and effort required.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If conventional bed sheets are used, then they can provide basic coverage, but they do not accommodate various mattress sizes effectively

Engineering Contradiction:

Improveadaptability to different mattress sizesVSAvoidcomplexity of bed sheet structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bed sheet uses dynamic corner elements with elastic members that can stretch and adapt to different mattress dimensions. The multiple independent panels can be arranged and adjusted to fit various mattress sizes while maintaining a relatively simple overall structure that does not require complex mechanisms for size adjustment.

Inventive Principle:

Principle #15Dynamics

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 solution allows for efficient and secure mattress covering, reducing the time and effort required for bed-making, preventing the sheet from coming undone during user movement, and maintaining integrity, thus enhancing user safety and aesthetic appeal.

Implementation Method 1

elastic members permit flexibility and stretching of the mattress covering. The elastic members may also prevent the mattress covering from ripping or tearing in the middle or along the edges and corners

AI summary

An adjustable bed sheet includes a sheet made of a first material. The sheet spans at least the length and the width of the mattress. A perimeter of the sheet is defined by edges thereof. The bed sheet also includes an elongated strip made of a second material that is more stretchable than the first material. The strip has a first elongated side opposite a second elongated side. The strip is attached, via the first elongated side, to an edge of the sheet such that, when the adjustable bed sheet is applied to the mattress, the strip is positioned, with respect to the mattress, to extend around at least one corner of the mattress from the length side of the mattress to the width side of the mattress. An end flap is attached to and hanging from the second elongated side of the strip.
