Pivotable Basket for Foldable Stroller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable strollers with slidable or demountable basket structures complicate the folding process and increase the number of components, making them inefficient and complex.
Innovation Solution
A basket device with a pivotable structure for a foldable stroller, featuring front and rear support units interconnected pivotally, rotatable clamping members, a curved frame, and a basket body made of soft material, allowing the curved frame to maintain a horizontal position due to tension, facilitating easy folding and reducing component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slidable or demountable basket structure is used, then the basket can be removed or adjusted, but the folding process becomes complicated and the number of components increases
Solution Approach 1:
The basket device is merged with the rear support unit through the curved frame that extends through passages in the clamping members, creating an integrated structure that eliminates the need for separate removal mechanisms while maintaining adjustability
Solution Approach 2:
The clamping members are designed to be rotatable relative to the pivot members, allowing dynamic adjustment of the basket position and enabling the structure to adapt between different states (folded/unfolded) without requiring demountable connections
2Adaptability or versatility
If a slidable or demountable basket structure is used, then the basket can be removed or adjusted, but the number of components increases
Solution Approach 1:
Multiple functions are merged into fewer components: the curved frame serves as both the basket support structure and the connection element to the rear support unit, while the clamping members provide both adjustment capability and structural support, reducing the total component count
Solution Approach 2:
The curved frame performs multiple functions simultaneously: it supports the basket body, connects to the rear support unit through the clamping members, and maintains structural integrity during folding operations, eliminating the need for separate components for each function
3Productivity
If a pivotable structure is used, then the folding efficiency is improved and component number is reduced, but the basket stability may be compromised
Solution Approach 1:
The clamping members are designed to be rotatable relative to the pivot members, allowing dynamic adjustment of the basket position and enabling the structure to adapt between different states (folded/unfolded) without requiring demountable connections
Solution Approach 2:
The curved frame is pre-configured to extend through the passages in the clamping members, establishing a stable geometric relationship that maintains basket stability while allowing the pivotable folding action to occur

AI summary
A basket device is used for a foldable stroller including front and rear support units. The rear support unit includes two rear support frames. The basket device includes two pivot members secured respectively to the rear support frames, two clamping members disposed respectively and rotatably on the pivot members, a curved frame, and a basket body made of a soft material. Each of the clamping members defines a passage. The curved frame has two opposite end portions extending respectively through the passages in the clamping members. The basket body has a front end fastened to the front support unit, and a rear end portion sleeved fixedly on the curved frame, such that the curved frame is generally horizontal.
