Solution Overview
Problem
Conventional blankets are often too short, leading to inadequate coverage and constant adjustments during sleep, and may not accommodate two people or secure properly on a bed, resulting in discomfort and frustration.
Innovation Solution
A pocket blanket device with an elastic pocket positioned along the bottom edge, which expands to fit over a mattress, securing the blanket in place with elastic elements and gathers, and features split sides for extra coverage, available in various sizes and materials to suit different needs and décor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional blankets are made larger to accommodate two people and prevent slipping, then coverage area is improved, but the blanket becomes too large to tuck in properly and difficult to secure on the bed
Solution Approach 1:
The blanket is segmented into a main body portion and a separate elastic pocket portion. The elastic pocket is attached to one end of the blanket body, allowing the blanket to be secured to the bed through the pocket while the rest of the blanket remains untucked and accessible. This segmentation resolves the contradiction by enabling secure attachment without requiring the entire blanket to be tucked in.
Solution Approach 2:
The elastic pocket acts as an intermediary element between the blanket and the bed. Instead of directly tucking the blanket under the mattress, the elastic pocket serves as a mediator that secures the blanket to the bed through elastic tension, making it easier to secure large blankets without manual tucking.
2Reliability
If conventional blankets are tucked in to prevent slipping, then security on bed is improved, but the blanket becomes too short to provide adequate coverage and may leave feet uncovered
Solution Approach 1:
The blanket design separates the security function (elastic pocket at one end) from the coverage function (main body extending beyond bed). This allows the tucked-in portion to be minimal while the uncovered portion provides adequate coverage, resolving the contradiction between security and coverage area.
Solution Approach 2:
The solution moves from a two-dimensional tucking problem to a three-dimensional solution by using the vertical dimension of the elastic pocket that can be stretched over the mattress. This allows the blanket to be secured without reducing the horizontal coverage area.
3Adaptability or versatility
If conventional blankets are made oversized to accommodate two people, then adaptability to different users is improved, but the blanket becomes difficult to secure and may be pulled off the bed
Solution Approach 1:
The elastic pocket introduces dynamic properties to the blanket system. The elastic material can stretch and contract, allowing the pocket to adapt to different mattress sizes and tensions while maintaining secure attachment. This dynamic characteristic enables the blanket to remain secure regardless of user size or bed configuration.
Solution Approach 2:
The elastic pocket changes the physical parameters of the blanket system by introducing elastic tension. This parameter change allows the blanket to be secured with minimal tucking while maintaining reliability, as the elastic tension compensates for the lack of extensive tucking required for oversized blankets.
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 pocket blanket device provides secure, oversized coverage for one or two people, preventing the blanket from shifting and ensuring comfortable sleep, while accommodating different mattress sizes and styles, and can be customized in design and material to fit individual preferences.

AI summary
The present invention relates to a novel pocket blanket device. The device is an improved blanket having an elastic pocket that can be placed over the bottom of a mattress to secure a blanket directly to the mattress. The device comprises a body component comprising a single body of material with an elastic pocket positioned along a bottom edge to be placed over the bottom of a mattress. The elastic pocket maintains the blanket in a secure position without worry of it being pulled too far to one side or pulled off the bed entirely. The blanket device also comprises multiple split sides which flare out or extend past the pocket which allows the blanket to lay flat and square on a bed in addition to providing extra blanket coverage for the users.
