Folding Handle Automatic Closure Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child strollers lack an efficient mechanism for automatically closing the folding handle after the stroller is folded, leading to a less neat and potentially hazardous storage condition.
Innovation Solution
A folding handle system comprising a handle body, a handle connecting member, and an elastic member, such as a torsion spring or contact bar, that automatically pivots the handle towards a closed position after the stroller is folded, ensuring the handle remains closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the folding handle is designed to be manually operable for folding the stroller, then the ease of operation is improved, but the automatic closure function is lost resulting in messy and potentially hazardous storage conditions
Solution Approach 1:
The folding handle incorporates an elastic member that automatically returns the handle body to its closed position after the stroller is folded, eliminating the need for manual adjustment and ensuring neat storage without compromising operational ease
Solution Approach 2:
The elastic member is pre-configured to exert a restoring force on the handle body, creating a preliminary counter-action that prevents the handle from remaining in an open or messy position, thereby addressing the storage safety issue before it can manifest
2Ease of manufacture
If the folding handle structure is simplified for easy manufacturing, then the ease of manufacture is improved, but the automatic closure mechanism becomes complex requiring additional components
Solution Approach 1:
The folding handle is divided into distinct functional segments: the handle body for user interaction, the shaft part for pivotal connection, and the elastic member for automatic closure. This segmentation allows each component to be manufactured independently using simple processes while collectively achieving the complex automatic closure function
Solution Approach 2:
The shaft part serves as an intermediary element that connects the handle body to the stroller frame and provides the pivotal axis. This intermediary component enables the automatic closure mechanism to function without requiring complex integration, as the shaft part naturally facilitates the rotational movement needed for handle closure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The automatic closure of the folding handle results in a neater and safer storage condition for the child stroller, preventing accidental opening and enhancing user convenience.
Implementation Method 1
an elastic member configured to force the handle body to pivot toward a closed position
Implementation Method 2
an elastic member, such as a torsion spring or contact bar

AI summary
The disclosure provides a folding handle, a folding device, a child stroller seat, and a child stroller. The folding handle includes: a handle body including a pulling part and a shaft part located at an end of the pulling part; a handle connecting member being fixable on the child stroller seat, and the handle body is pivotally connected to the handle connecting member via the shaft part; and an elastic member configured to force the handle body to pivot toward a closed position. The folding handle according to the disclosure can be automatically closed after the child stroller seat is folded, such that the folded child stroller is more neat and aesthetic, and potential dangers are avoided.
