Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for keeping infants warm in their sleep environment, such as wearable blankets and sleep sacks, pose risks of limb restriction, loose objects, and potential hazards, and do not meet safety guidelines set by the American Academy of Pediatrics.

Innovation Solution

A fitted bed sheet with an attached blanket featuring a left flap and right pocket, secured with hook and loop fasteners, where the blanket is made of elastane material to adjust snugness and is permanently attached to the sheet, ensuring the blanket remains in place and free of loose objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a wearable blanket or sleep sack is used to keep the infant warm, then the infant's warmth is improved, but the risk of limb restriction and loose objects causing SIDS increases

Engineering Contradiction:

Improveinfant warmthVSAvoidlimb restriction and loose object hazards

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The patent combines the fitted sheet and blanket into a single integrated unit where the blanket is permanently attached to the sheet through stitching. This merging eliminates the loose blanket hazard while maintaining warmth, and the fitted sheet portion secures the blanket to the mattress preventing detachment that could cause limb restriction or SIDS risks.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fitted sheet portion acts as a flexible securing mechanism that wraps around and attaches to the mattress, holding the blanket in place. This flexible attachment system prevents the blanket from becoming loose or detaching while allowing natural infant movement without restriction.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of manufacture

If a detachable fitted sheet and blanket are used, then ease of washing is improved, but the risk of blanket detachment and loose objects increases

Engineering Contradiction:

Improveease of washingVSAvoidblanket detachment hazard

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The blanket and fitted sheet are permanently stitched together to form a single non-detachable unit. This ensures the blanket cannot become loose or detach from the sheet, eliminating the hazard while still allowing the entire combined unit to be removed and washed as one piece.

Inventive Principle:

Principle #5Merging (Combining)

3Temperature

If traditional swaddling is used to keep the infant warm, then warmth is improved, but limb movement is restricted

Engineering Contradiction:

Improveinfant warmthVSAvoidlimb movement freedom

Core Design Contradiction:

TemperatureVSEase of operation

Solution Approach 1:

The invention divides the infant's body into different zones: the fitted sheet portion secures the blanket to the mattress, the blanket provides warmth, and the left flap specifically covers only the infant's tummy area. This segmentation allows natural limb movement while maintaining warmth and security where needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The left flap is positioned specifically to cover the infant's tummy area rather than wrapping around the entire body. This localized coverage provides warmth to the core area while leaving limbs free to move naturally, avoiding the restriction problems of traditional full-body swaddling.

Inventive Principle:

Principle #3Local quality
