Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant care devices, such as bouncy seats and baby swings, are limited in their ability to replicate the complex motion profiles of a caregiver, often providing only single-dimensional motorized motion, which restricts their ability to effectively soothe and entertain infants.
Innovation Solution
A motorized infant chair with a drive mechanism that allows simultaneous or independent movement in both horizontal and vertical directions, utilizing a combination of horizontal and vertical reciprocating assemblies controlled by a controller to generate a variety of motion profiles, including both horizontal and vertical movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-degree motorized motion is used, then the device complexity is reduced, but the adaptability of motion profiles is limited
Solution Approach 1:
The patent transitions from single-degree freedom (one-dimensional motion) to two-degree freedom (two-dimensional motion) by adding both horizontal and vertical reciprocating assemblies. This dimensional expansion enables multiple motion profiles (rocking, bouncing, swinging) without requiring complex multi-axis robotic systems, achieving versatility through geometric composition rather than computational complexity.
Solution Approach 2:
The drive mechanism is segmented into independent horizontal and vertical reciprocating assemblies, each controlled by separate motors. This modular segmentation allows each component to remain relatively simple while the combination produces complex motion profiles, resolving the contradiction between adaptability and complexity through functional decomposition.
2Adaptability or versatility
If only vertical motion is provided, then the device structure is simplified, but the ability to mimic caregiver motion is reduced
Solution Approach 1:
The patent adds horizontal motion capability to the traditional vertical-only baby swing by incorporating a horizontal reciprocating assembly. This enables the system to generate diverse motion profiles including side-to-side rocking, diagonal bouncing, and coordinated swinging patterns that better replicate natural caregiver motions, achieving enhanced adaptability through spatial expansion.
3Ease of operation
If a motorized mechanism is added to provide automated motion, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent employs dynamic motion profiles where the horizontal and vertical motors can operate independently or in coordination, with variable speeds and amplitudes controlled by a controller. This dynamic control system allows automated operation with minimal user intervention while maintaining manageable complexity through programmable motion sequences rather than mechanical complexity.

AI summary
An infant care apparatus includes a base; a drive mechanism disposed on the base; a controller electronically coupled to the drive mechanism; and a support device coupled to the drive mechanism. The support device is configured to be moved in both a horizontal and vertical direction relative to the base by the drive mechanism. The drive mechanism is controlled by the controller to move the support device in a plurality of motion profiles relative to the base.
