Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocking devices for pushchairs require continuous manual operation, limiting user activity and hindering independent sleep learning in children, as they lack reliability and control in rocking movements.
Innovation Solution
A collapsible rocking device with a frame, adjustable arms, collapsing mechanisms, and a controller-driven system that allows for controlled oscillating movement of pushchair wheels, enabling automatic and adjustable rocking with ease of transport and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rocking device is provided with a drive engaging on a wheel of the pushchair, then automatic rocking is achieved, but reliability and control of the rocking movement deteriorates
Solution Approach 1:
The patent introduces wheel holders as intermediary components that receive the pushchair wheels and guide them along fixed guides. This intermediary mechanism ensures controlled motion paths and prevents uncontrolled turning or rolling, thereby improving reliability and control while maintaining automatic rocking functionality.
Solution Approach 2:
The patent employs resilient or damping effects to dynamically adjust the rocking movement. The resilient element stores and releases energy to provide smooth oscillating motion, while damping effects control the motion to prevent excessive movement, enhancing both reliability and control of the automatic rocking system.
2Ease of operation
If the rocking device is made collapsible, then ease of transport is improved, but device complexity increases
Solution Approach 1:
The patent divides the rocking device into collapsible segments, specifically the guides can be folded or collapsed into each other. This segmentation allows the device to be compacted for easy transport while maintaining the complete functional structure when deployed, balancing portability with operational integrity.
3Reliability
If wheel holders make translating movement over guides, then controlled rocking motion is achieved, but device complexity increases
Solution Approach 1:
The patent uses resilient or damping effects within the wheel holder mechanism to achieve controlled oscillating translating movement. These dynamic elements provide automatic control of the rocking motion without requiring complex external control systems, thereby achieving reliable controlled motion while minimizing added complexity.
