Elastic Bed Covering Straps to Prevent Mattress Slippage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed coverings often become dislodged during sleep, requiring frequent re-making of the bed and leaving occupants uncomfortable and uncovered, as they lack effective and non-damaging securing mechanisms.
Innovation Solution
A bed covering with an integral stretchable, flexible member attached to its underside, near the bottom corners, which securely attaches to the mattress, preventing it from shifting and keeping sheets and blankets in place, using a wide elastic strip with a no-slip texture for stability and adjustable fastening for various mattress thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a loose bed covering is used, then the bed covering is comfortable and easy to place, but it becomes dislodged during sleep requiring frequent re-making
Solution Approach 1:
The patent combines the bed covering with an integrated securing strap system into a single unified product. The strap is permanently attached to the bed covering, eliminating the need for separate securing devices and simplifying the bed-making process while maintaining stability.
Solution Approach 2:
The strap acts as an intermediary element that connects the bed covering to the mattress. It mediates between the loose bed covering and the mattress surface, providing secure attachment without requiring modifications to either the bed covering or mattress.
2Reliability
If attaching means are added to secure the bed covering, then stability improves, but the bed covering may be damaged by clamps, devices or attachments
Solution Approach 1:
The patent uses a flexible fabric strap instead of rigid clamps or hard attachment devices. The soft, flexible material of the strap prevents damage to the bed covering while providing effective securing through friction and tension.
Solution Approach 2:
The strap is constructed from composite materials including elastic fibers and friction-enhancing surfaces, combining flexibility with securing capability. This allows the strap to be gentle on the bed covering while maintaining strong holding power.
3Reliability
If straps are used to secure the bed covering, then stability improves, but the straps may slip off the corner of the foot of the mattress
Solution Approach 1:
The patent gives the strap a curved or angled configuration that follows the contour of the mattress corner. This curved design allows the strap to wrap around and grip the corner more effectively, preventing slippage compared to straight straps.
Solution Approach 2:
The strap extends from the side of the bed covering toward the foot end, creating a diagonal or angular orientation rather than a straight horizontal or vertical alignment. This dimensional change allows the strap to engage the mattress corner more effectively and resist slipping.
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 ensures the bed covering remains in place during sleep, reducing the need for frequent re-making and maintaining occupant comfort by securely fastening the bed covering and underlying sheets to the mattress, while being easy to apply and durable.
Implementation Method 1
a stretchable, flexible member attached to the under-side of a covering piece, near the bottom corners of the covering piece
Implementation Method 2
using a wide elastic strip with a no-slip texture for stability

AI summary
An improved bed covering comprising a generally rectangular cover piece and an elastic member attached to the bottom side of the cover piece near the bottom of the bed. The member comprising an adjusting means and having sufficient length to extend under a mattress such that the member is not visible while the covering is positioned on the bed.
