Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Housekeeping employees in hotels, motels, and healthcare facilities face significant back problems due to repetitive lifting of heavy mattresses during bed-making, which is exacerbated by the use of flat sheets, and fitted sheets do not fully address the issue while being more costly and prone to wear out quickly.

Innovation Solution

A modular, easily removable mattress cover with a fabric substrate and resilient members that allows for tucking between the mattress and box spring without lifting, reducing the need for mattress lifting during bed-making.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If flat sheets are used for bed-making, then inventory costs are reduced and fewer items need to be maintained, but the number of mattress lifting operations increases significantly

Engineering Contradiction:

Improvenumber of sheet items in inventoryVSAvoidease of bed-making operation

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The invention divides the bed-making process into two independent parts: the flat sheet that remains on the mattress surface, and the mattress cover that is tucked underneath. This segmentation allows the flat sheet to stay in place without requiring mattress lifting, while the mattress cover handles the tucking function separately.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mattress cover acts as an intermediary component between the flat sheet and the box spring. It provides the necessary grip and structure for tucking underneath the mattress without requiring the flat sheet to be lifted, thus mediating the bed-making process to eliminate heavy lifting operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If fitted sheets are used for the bottom sheet, then the number of mattress lifting operations is reduced by 40%, but the cost increases and the elastic wears out quickly requiring frequent replacement

Engineering Contradiction:

Improveease of bed-making operationVSAvoiddurability of sheet

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The invention separates the functions of the bottom sheet into two components: a durable flat sheet for the visible surface, and a separate mattress cover with resilient members for the tucking function. This segmentation allows each component to be optimized independently - the flat sheet for durability and aesthetics, the mattress cover for functional performance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mattress cover is designed as a replaceable component that can be washed and maintained separately from the expensive flat sheet. When the resilient members wear out, only the mattress cover needs replacement, not the entire sheet set, reducing overall costs and extending the lifecycle of the primary bedding items.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If fitted sheets are used, then mattress lifting is reduced, but the elastic in fitted sheets wears out quickly due to frequent washing in commercial facilities

Engineering Contradiction:

Improveease of bed-making operationVSAvoidservice life of sheet

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The invention divides the bedding system into a permanent flat sheet and a washable mattress cover with resilient members. The flat sheet remains in service indefinitely without elastic degradation, while the mattress cover is designed for periodic replacement after extended use in commercial washing environments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mattress cover is designed as a consumable component that can be removed, washed, and eventually replaced. The flat sheet is recovered and retained for long-term use, separating the disposable elastic components from the durable fabric components to maximize overall service life.

Inventive Principle:

Principle #34Discarding and recovering

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 enhances bed-making efficiency, reduces employee strain, and maintains aesthetic neatness, while being cost-effective and durable.

Implementation Method 1

a resilient member, such as an elastic, configured to be received within a pocket of the mattress cover. The resilient member is configured to grip the mattress and resist outward forces applied to the mattress cover

Methodology Applied

AI summary

A cover includes a fabric substrate including a top surface, foot portion, first side portion, and second side portion. At least a portion of a first edge of the foot portion is stitched or sewn together with at least a portion of the first side portion. At least a portion of a second edge of the foot portion is stitched or sewn together with at least a portion of the second side portion. At least a portion of a head portion of the cover is disposed along a bottom surface of the fabric substrate. At least a portion of a first edge of the head portion of the cover is stitched or sewn together with an outer edge of the first side portion and at least a portion of a second edge of the head portion is stitched or sewn together with an outer edge of the second side portion.
