Infant Leg Trainer Partition Resilient Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for strengthening infant leg and foot muscles, such as swaddling, are inadequate in providing reflex stimuli for limb extension and flexion recoil, limiting effective muscle development in infants, especially those in neonatal care.
Innovation Solution
A leg and foot strength training device comprising a support bed with a partition that forms a cavity, providing resilient resistance to infant kicks and pushes, using various resistance components like elongated flexure members, planar flexure members, elastic members, and adjustable electromechanical components to customize resistance levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If swaddling is used to confine an infant, then containment is provided to simulate being in the womb, but reflex stimulus for limb extension and flexion recoil is not provided
Solution Approach 1:
The device divides the containment space into segments: a general support bed and a specific cavity partition. The partition segments the space to create a focused interaction zone that provides both containment and reflex stimulus, resolving the contradiction by separating the containment function from the stimulus function into distinct structural elements.
Solution Approach 2:
The resilient partition acts as an intermediary between the infant's limbs and the support bed. It mediates the interaction by providing both containment (through the cavity structure) and reflex stimulus (through resilient resistance), thus resolving the contradiction where swaddling provided containment but lacked reflex stimulus.
2Strength
If a partition provides resilient resistance to infant kicks, then muscle strength training is achieved, but the device structure becomes more complex
Solution Approach 1:
The partition is constructed using flexible, resilient materials that can be integrated into the support bed structure. This approach provides the necessary muscle strength training through resilient resistance while minimizing device complexity by using flexible components rather than rigid mechanical systems.
Solution Approach 2:
The resilient properties of the partition can be adjusted by changing material parameters or structural configuration. This allows the device to provide appropriate muscle strength training while maintaining a simple overall structure, as the resistance characteristics can be modified through material selection rather than complex mechanical adjustments.
3Ease of operation
If the partition is made resilient to provide resistance, then reflex stimulus is enhanced, but the comfort and support for the infant may be reduced
Solution Approach 1:
The resilient partition provides localized resistance only in the cavity area where infant limbs interact with it, while the rest of the support bed maintains soft, comfortable support. This local differentiation of material properties enhances reflex stimulus where needed without compromising overall infant comfort.
Solution Approach 2:
The partition provides resilient resistance only partially - when and where the infant's limbs contact it during movement. The resistance is not continuous or excessive, but rather occurs in controlled portions during natural limb extension and flexion, providing reflex stimulus while maintaining comfort during periods of non-interaction.
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 device effectively stimulates muscle strength in infants by providing controlled resistance, mimicking the womb environment and allowing for adjustable resistance levels based on the infant's strength, thereby enhancing muscle development and reflex stimulation.
Implementation Method 1
The partition is configured to provide resilient resistance to force applied from within the cavity

AI summary
A leg and foot strength training device for infants. The device includes a support bed and a partition at one end of the support bed. The partition cooperates with the support bed to form a cavity. An infant lying on the support bed maybe positioned such that their legs and feet maybe located substantially within cavity. When the infant pushes or kicks his or her legs or feet toward and/or against the partition from within cavity, the partition may provide an amount of resilient resistance against the legs or feet kicks or pushes.
