Stroller Wheel Rocker With Removable Drive for Portable Soothing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocker products for soothing children and babies are not portable and often require tedious manual effort, with existing solutions being bulky and prone to mechanical failures.
Innovation Solution
A rocker system for wheeled carriages that includes a first attachment device for the frame, a second attachment device for the wheel, and a movement mechanism connecting the two, featuring a single-unit arm and removable components for ease of use and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If motorized rocking systems are used in cradles and baby swings, then the rocking function is automated and effective, but the devices become bulky and unwieldy to transport
Solution Approach 1:
The rocker system is divided into separate components: a movement mechanism with motor that can be detached from the stroller frame. This allows the automated rocking function to be separated from the main stroller structure, enabling portability when the mechanism is not in use while maintaining automation when attached
Solution Approach 2:
The system transitions from a static bulky device to a dynamic, reconfigurable system where the movement mechanism can be attached or detached from the stroller frame based on whether rocking function is needed, optimizing both portability and automation at different times
2Ease of operation
If extendable arm assembly with joint is used to rotate the wheel, then the rocking motion can be achieved, but the joint becomes a failure point and installation becomes difficult
Solution Approach 1:
The problematic joint is completely removed from the design. Instead of using an extendable arm assembly with a joint, the patent employs a solid arm assembly that directly connects the movement mechanism to the wheel, eliminating the joint and its associated reliability issues while maintaining the rocking motion capability
3Ease of operation
If extendable arm assembly with joint is used, then the wheel can be rotated back and forth, but the mechanism becomes difficult to install and remove
Solution Approach 1:
The system is segmented into modular components that can be easily attached and detached. The movement mechanism with solid arm assembly connects to the stroller frame through simple attachment points, making installation and removal straightforward compared to complex jointed arm assemblies

AI summary
A rocker system for a wheeled carriage (such as a stroller for a child or infant) may include a first attachment device for attaching the rocker system to an object (such as a frame of a stroller or a fixed object such as a wall), a second attachment device for attaching the rocker system to a wheel, and a movement mechanism operatively connecting the first attachment device to the second attachment device. The movement mechanism causes the second attachment device to move the wheel back and forth. The movement mechanism may be removable from, and replaceable on, the first attachment device. The movement mechanism may include an actuator that moves an arm and the second attachment device. The arm may be neither extendable nor retractable.
