Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strollers lack easy disassembly and assembly features, making it difficult for parents to simultaneously care for a child and carry items, especially in scenarios requiring additional load management.
Innovation Solution
A children's stroller with a frame design that includes detachable support rods, auxiliary item-carrying frames, and quick-connect wheel assemblies, allowing for easy disassembly and assembly to accommodate both children and items, and featuring a folding mechanism for adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the stroller frame is made as a single integrated structure, then the structural strength and stability are improved, but the ease of disassembly and assembly deteriorates
Solution Approach 1:
The stroller frame is divided into multiple detachable components including front support rod, rear support rod, side frames, and wheel modules. These segments are connected through quick-connect mechanisms with locating pins and elastic buttons, allowing easy separation while maintaining structural integrity when assembled.
Solution Approach 2:
The detachable support rods and auxiliary item-carrying frames are designed to nest within or attach to the main frame structure. The auxiliary frames can be stored within the accommodating space when not in use, and quickly deployed when needed, maximizing space utilization and ease of operation.
2Ease of manufacture
If the stroller frame is made as a fixed non-detachable structure, then the manufacturing complexity is reduced, but the adaptability to different usage scenarios deteriorates
Solution Approach 1:
The stroller frame transitions from a static fixed structure to a dynamic reconfigurable system. The front and rear support rods can be detached and reattached at different positions, and auxiliary item-carrying frames can be added or removed based on whether items or children need to be transported, providing adaptability while maintaining relatively simple manufacturing processes.
Solution Approach 2:
The detachable support rods and auxiliary item-carrying frames serve multiple functions: they provide structural support when assembled, enable easy disassembly for storage or transport, and can be reconfigured for different usage scenarios such as carrying children alone, carrying items alone, or both simultaneously.
3Ease of operation
If the support rods are made detachable, then the ease of operation for disassembly is improved, but the reliability of the connection deteriorates
Solution Approach 1:
Locating pins and elastic buttons serve as intermediary elements between the support rods and frame components. The locating pins guide precise alignment during assembly, while the elastic buttons provide automatic locking and audible feedback, ensuring reliable connections without requiring complex fastening mechanisms.

AI summary
A children's stroller with easy disassembly and assembly features are provided. The stroller includes a frame, a wheel module disposed below the frame, and a stroller module disposed above the frame. The frame cooperates with the wheel module via the stroller module to move. By disposing connecting buckle at the front and rear ends of the first and second side frames, and providing connection slots on the front and rear support rods, the front and rear support rods are detachably disposed at the front and rear ends of the first and second side frames by fitting the connection slots and connection locking blocks. When it is necessary to carry items, the front or rear support rod can be detached to forming an opening at the front or rear side of the side frame that connects to the storage space.
