Child Seat Track Assembly for Multi-Axis Soothing Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child motion devices typically offer limited seating positions and motion characteristics, often featuring a single pivot axis, which can be noisy and cumbersome, failing to provide the varied soothing motions that parents naturally offer.
Innovation Solution
A child motion device with a frame assembly and tracks that allow the seat to move in multiple motion paths, including side-to-side gliding, rocking, and bouncing, powered by an electric motor, enabling various seating orientations and motion characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single pivot axis is used in conventional child motion devices, then the device structure is simple, but the motion characteristics are limited and noisy
Solution Approach 1:
The motion device is divided into multiple independent pivot axes (first pivot axis for rocking motion, second pivot axis for gliding motion) that work together to create complex motion patterns. This segmentation allows each axis to provide a specific type of motion while collectively achieving versatile motion characteristics that would be impossible with a single pivot axis.
Solution Approach 2:
The invention transitions from single-axis (one-dimensional) motion to multi-axis (multi-dimensional) motion by introducing additional pivot axes. The first pivot axis provides rocking motion in one plane, while the second pivot axis adds gliding motion in a different plane, creating two-dimensional or three-dimensional motion trajectories that enhance adaptability.
2Extent of automation
If a motor is mounted above the child's head to provide automatic movement, then the device can provide continuous motion, but it creates noise and takes up space
Solution Approach 1:
The motor is extracted from its traditional position above the child's head and relocated to a different position in the device structure. This extraction removes the noise source from proximity to the child while maintaining the motor's function of providing automatic motion through the pivot axes.
Solution Approach 2:
The invention introduces mechanical linkages and pivot axes as intermediaries between the motor and the seat. The motor drives these intermediate components, which in turn produce the desired motion at the seat, allowing the motor to be positioned away from the child while still providing automatic motion.
3Adaptability or versatility
If a single seating orientation is provided, then the device structure is simple, but it lacks versatility for different child positions
Solution Approach 1:
The seat assembly is designed with dynamic, adjustable characteristics that allow it to assume multiple seating orientations. Instead of a fixed single-position seat, the seat can be adjusted to different angles and positions, accommodating various child seating preferences and parental needs while integrated with the multi-axis motion system.

AI summary
A child motion device has a frame assembly configured to rest on a support surface. The frame assembly includes at least one track configured to slidably receive a child seat assembly. The track can extend in any desired direction and include a geometric profile so that as the seat assembly travels along the track, a desired motion profile is imparted onto the seat assembly and to the child seated therein.
