Fitted Blanket Zipper Structure for Stable Mattress Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blankets fail to stay in place on a mattress, often moving off during sleep and requiring frequent adjustment, and lack easy access mechanisms for entry and exit.
Innovation Solution
A fitted blanket with an elastic band along its underside and a zipper or other connection mechanism that runs from the pillow cut-out to the foot end, allowing secure attachment to the mattress and easy opening and closing for user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional blanket is laid over or tucked under a mattress, then the blanket can cover the user, but the blanket cannot stay in place and moves off during sleep
Solution Approach 1:
The blanket is divided into a top sheet portion and a fitted sheet portion with separate functions. The fitted sheet portion with elastic bands secures the blanket to the mattress, while the top sheet provides coverage. This segmentation allows the blanket to stay in place without requiring frequent adjustments.
Solution Approach 2:
The invention extends the blanket functionality into a third dimension by adding a fitted sheet portion that goes underneath the mattress. This dimensional change from a simple top layer to a multi-layer structure with vertical extension enables secure attachment and prevents slippage.
2Ease of operation
If a conventional blanket is tucked under the mattress, then the blanket can stay on the bed, but there is no easy access mechanism for entry and exit
Solution Approach 1:
The blanket incorporates a dynamic opening and closing mechanism via a zipper that runs along the side. This allows the blanket to transition between open and closed states, enabling easy entry and exit while maintaining security when zipped closed. The dynamic nature of the zipper resolves the contradiction between accessibility and stability.
3Reliability
If a fitted blanket includes secure attachment mechanisms, then the blanket stays in place, but the blanket lacks easy access for getting in or out of bed
Solution Approach 1:
The zipper mechanism serves multiple functions: it provides easy access for entry and exit, allows the blanket to be quickly adjusted, and can be used to secure or release the blanket as needed. This multi-functionality reduces the perceived complexity by making a single mechanism perform several useful tasks.
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 fitted blanket securely stays on the mattress, preventing slippage and movement, while allowing easy entry and exit, maintaining warmth and convenience for users throughout the night.
Implementation Method 1
an elastic band region running along at least a portion of an outer periphery of the fitted bedding material

AI summary
A fitted blanket fits over a mattress and secures underneath to prevent the blanket from moving off the user while sleeping in bed. The blanket can include an elastic material on at least the underside corner edges thereof. Children and adults alike can stay warm at night as their blankets cannot fall away or off of them while sleeping. The fitted blanket may further include an opening and closing mechanism to allow for easy entry and exit, rather than having to untuck the blanket, as is the case with conventional blankets. The opening and closing mechanism may also provide an easy way to make the bed. The fitted nature of the blanket prevents blanket slippage or movement. The blanket may further include a cut-out region for pillow placement. The blanket can also include glow-in-the-dark elements or illuminated elements to light up the blanket at night.
