Folding Stroller Bracket Mechanism for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding strollers have complex folding mechanisms, are cumbersome to fold, prone to finger pinching, and have a large volume when folded, making them inconvenient for storage and transportation.
Innovation Solution
A folding stroller with a simple structure featuring a framework with a first and second bracket assembly, a connecting bracket assembly, and a supporting assembly that allows for easy switching between folded and unfolded states, along with a locking assembly for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional folding mechanism with many rods is used, then the stroller can be folded, but the folding component becomes complex and the folding operation becomes cumbersome
Solution Approach 1:
The folding mechanism is divided into independent functional modules: the supporting assembly with sliding end and connecting end, the connecting bracket assembly, and the locking assembly. Each module performs a specific function, simplifying the overall structure while maintaining folding capability. The supporting assembly handles the folding motion, the connecting bracket assembly manages the geometric transformation, and the locking assembly ensures stability, eliminating the need for complex multi-rod mechanisms.
2Object-affected harmful factors
If a traditional folding mechanism is used, then the stroller can be folded, but it is easy to pinch the fingers of a user during folding
Solution Approach 1:
The supporting assembly acts as an intermediary between the user's folding action and the bracket assembly. The sliding end moves along predefined guide rails or slots, controlling the folding motion path to avoid direct pinching points. The connecting end rotates relative to the connecting bracket assembly in a controlled manner, creating safety distances that prevent finger pinching while maintaining ease of operation.
3Volume of moving object
If a traditional folding mechanism is used, then the stroller can be folded, but the folded product has a large volume making it inconvenient to carry
Solution Approach 1:
The supporting assembly is designed to nest within the bracket assembly structure when folded. The sliding end retracts along the guide rails into the space between the first and second bracket assemblies, while the connecting end folds against the connecting bracket assembly. This nesting arrangement minimizes the overall folded volume, making the stroller compact and portable while maintaining simple operation.
4Stability of the object's composition
If a traditional folding mechanism is used, then the stroller can be folded, but the stroller is not stable in a folded state and easily deforms
Solution Approach 1:
The locking assembly is designed to automatically engage in advance before the folding mechanism completes its motion. The locking block moves along the guide rail and engages with the locking hole预先, securing the bracket assembly in its folded position before any potential deformation can occur. This preliminary locking action ensures stability without requiring complex additional support structures.
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 stroller achieves a compact, stable folded state for easy storage and transportation, while providing a spacious and stable unfolded state for use, with improved safety and convenience.
Implementation Method 1
the elastic member drives the locking block to move towards the locked position
Implementation Method 2
a connecting end of the supporting assembly is rotatably connected to the connecting bracket assembly
Implementation Method 3
a sliding end of the supporting assembly is slidably connected to the first bracket assembly and the second bracket assembly
