Devices and methods for supporting and containing premature babies and small-for-age infants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant support devices are inadequate for premature and small-for-age infants, particularly those under two kilograms, as they fail to provide proper support and can cause deformational plagiocephaly due to their hard surfaces and inability to adjust to the infant's size, leading to permanent head deformities if pressure is continuously applied.
Innovation Solution
A support device with a shape-adjustable fabric surface and discrete compressible materials, including a layer of foam with a concave head cavity, that can be molded to fit the infant's head and torso, providing a customizable boundary to prevent and correct deformational plagiocephaly, and a containment device with moveable arms to secure the infant, ensuring proper positioning and reducing the risk of head flattening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hard support surface is used, then structural stability is improved, but head deformation risk increases
Solution Approach 1:
The patent applies parameter changes by transitioning from a hard, rigid support surface to a soft, compliant surface that can dynamically adjust its physical properties. The soft support device changes its firmness and contour parameters to match the infant's head shape, providing both stability and deformation prevention through material compliance rather than rigidity.
Solution Approach 2:
The patent employs composite materials by combining soft fabrics with internal structural elements (such as foam layers or adjustable filling materials) to create a multi-layered support device. This composite structure provides both the soft external surface that prevents head deformation and the internal framework that maintains structural stability and support.
2Ease of manufacture
If a fixed-size support device is used, then manufacturing simplicity is improved, but adaptability to different infant sizes deteriorates
Solution Approach 1:
The patent applies dynamics by incorporating adjustable and reconfigurable elements into the support device. The device includes movable components, adjustable filling levels, and flexible structures that can be dynamically modified to accommodate different infant sizes and growth stages, transforming a static device into an adaptive system.
Solution Approach 2:
The patent employs segmentation by dividing the support device into modular components that can be independently adjusted or reconfigured. This includes separable layers, adjustable sections, and modular elements that allow the device to be customized for different infant sizes without requiring complete redesign or remanufacturing.
3Adaptability or versatility
If discrete compressible materials are added, then shape adjustability is improved, but device complexity increases
Solution Approach 1:
The patent applies self-service by designing the support device to automatically adapt to the infant's head shape without requiring complex external control systems. The discrete compressible materials self-adjust and redistribute under the infant's weight, providing shape customization through passive physical mechanisms rather than active control, thereby maintaining simplicity.
4Object-affected harmful factors
If the support device is made soft, then comfort is improved, but support firmness deteriorates
Solution Approach 1:
The patent employs composite materials by combining soft fabrics with internal structural elements (such as foam layers or adjustable filling materials) to create a multi-layered support device. This composite structure provides both the soft external surface that prevents head deformation and the internal framework that maintains structural stability and support.

Function Achieved in This Case
The solution effectively reduces the incidence of head flattening and elongation, provides anatomical correction, and accommodates the infant's growth by allowing adjustments to the support device's shape and insert size, ensuring a comfortable and safe environment for premature and small-for-age infants.

AI summary
Infant support devices and containment devices are described for use with premature and small-for-age infants, and in particular premature babies two kilograms or less, and even babies of one kilograms or less. The devices can be used separately or in combination (whereupon both support and containment are achieved together).
