Motorized Stroller Swing Seat With Overhead Pivot Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant strollers often require manual operation, are surface-dependent, and may not provide a suitable swinging motion for relaxation, with some designs being complex and costly to manufacture.
Innovation Solution
A stroller with a seat that swings about an axis of rotation above the infant's body, powered by motors, allowing for hands-free operation and a decoupled motion from the surface, featuring a simple and cost-effective design with adjustable components and battery-powered motors that can recharge through wheel motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stroller uses manual operation with surface-dependent movement, then it is simple to manufacture, but it cannot provide a suitable swinging motion for infant relaxation and requires constant manual operation
Solution Approach 1:
The patent replaces manual mechanical operation with an automated motorized system. A motor mounted on the chassis drives a pivot mechanism that rotates the seat about an axis above the infant's body, eliminating the need for manual pushing and providing automated swinging motion for infant relaxation.
Solution Approach 2:
The stroller system performs the swinging function automatically through the motorized mechanism. The motor continuously or periodically actuates the pivot to create rhythmic swinging motion without requiring external manual intervention, allowing the system to serve itself in providing the therapeutic swinging motion.
2Ease of manufacture
If a stroller produces a rocking motion with the axis of rotation at or below the infant's body, then it is simple to design, but it is less conducive to infant relaxation
Solution Approach 1:
The patent changes the critical parameter of axis of rotation positioning from at or below the infant's body to above the infant's body. This parameter change transforms the motion characteristics from simple rocking to a more effective swinging motion that better promotes infant relaxation, while the motorized system provides the necessary torque to achieve this higher pivot point rotation.
3Ease of operation
If a stroller uses a motorized swing mechanism with axis above the infant's body, then it provides better swinging motion for relaxation, but it increases device complexity and manufacturing cost
Solution Approach 1:
The motorized pivot assembly serves multiple functions: it provides the swinging motion for infant relaxation, enables hands-free operation, and can potentially accommodate different swing speeds and durations. By integrating the motor directly onto the chassis and using it to drive the pivot mechanism, the system achieves multi-functionality without proportionally increasing complexity.

AI summary
A stroller (201) is provided which includes a chassis (203, 205) having first (211) and second (213) opposing frame elements. The chassis is supported on a plurality of wheels (223, 224, 225, 226). A seat (231) is suspended from the chassis by way of a support element (241). The seat includes upper (233) and lower (235) portions and is adapted to accommodate a child such that the back of the child rests against the upper portion and such that the legs of the child rest against the lower portion. The support element has first and second ends which are rotatably attached to first (243) and second (245) pivots mounted, respectively, on the first and second frame elements. The first pivot rotates about a first axis, and the seat is disposed between the first axis and the plurality of wheels. A first motor (271) is provided which rotates the first pivot.
