Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double child strollers face issues with large folded sizes, inconvenient storage, minimal seating for occupants, and lack of a raised seat for younger children, while compactly foldable strollers compromise on seat size and basket storage.
Innovation Solution
A child stroller design featuring a stroller frame with foldable sections, a detachable first seat, and a bench seat that can rotate and fold, allowing for compact storage and adjustable seating configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional double child stroller structure is used, then seating capacity is provided, but folded size becomes large and storage becomes inconvenient
Solution Approach 1:
The stroller is divided into two main sections: a first section with a first seat for an older child and a second section with a second seat for a younger child. The sections can be independently folded and stored, allowing the stroller to be compacted to a smaller size while maintaining seating capacity for two children.
Solution Approach 2:
The second seat is positioned within the first seat structure, with the second seat back disposed at the rear of the first seat. This nested arrangement allows both seats to occupy overlapping space, significantly reducing the overall folded volume while maintaining dual seating capability.
2Volume of moving object
If compact folding is achieved, then storage convenience improves, but seat space and basket storage are reduced
Solution Approach 1:
The seat backs are designed to be movable relative to the seat frames. The first seat back can be rotated between a first position for compact storage and a second position for expanded seating. Similarly, the second seat back can be rotated between a third position for compact folding and a fourth position for expanded seating space.
Solution Approach 2:
The stroller frame is divided into two independently foldable sections, each with its own seat assembly. This allows one section to be folded compactly for storage while the other section remains unfolded to maintain adequate seat space for a child.
3Adaptability or versatility
If conventional stroller design is used, then basic seating is provided, but raised seat for younger child near parent is not available
Solution Approach 1:
The second seat is designed with multi-position capability through rotatable seat backs. The second seat back can be rotated to a fourth position that raises the younger child's seating position, allowing the child to be near the parent's shoulder level. This same mechanism also provides compact folding when the seat back is in the third position.

AI summary
A child stroller includes a stroller frame and a first seat. The stroller frame has two sections capable of being folded and unfolded relative to each other. The first seat is disposed on one of the two sections in a detachable manner. The first seat includes a supporting unit and a first seat frame. The first seat frame is adapted to hold the supporting unit. The first seat frame includes a seat hub, an upper seat tube and a lower seat tube. The seat hub is disposed on the stroller frame. The upper seat tube is disposed on the seat hub, and the supporting unit is slidably disposed on the upper seat tube. The lower seat tube is disposed on the seat hub and detachably connected to the supporting unit.
