Foldable Basket With Movable Upper Frame and Access Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable plastic baskets are cumbersome to fold and access items due to complex folding sequences and the need to remove stacked baskets to access contents, leading to inefficiency in storage and retrieval.
Innovation Solution
A foldable basket design featuring a moving upper frame and integrated door that allows for easy expansion and collapse, with all walls made as single pieces for increased rigidity, and a door mechanism that opens to access items without removing stacked baskets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the upper ends of the left and right walls are detached from the upper frame for folding, then the basket can be folded flat for storage, but the folding sequence becomes more complex and operation more difficult
Solution Approach 1:
The upper frame is designed to move dynamically along the left and right walls through guide grooves and sliders, enabling automatic alignment during folding without complex manual manipulation. The movable upper frame adapts its position automatically as the basket transitions between folded and unfolded states, simplifying the folding sequence while maintaining volume reduction capability.
2Volume of moving object
If baskets are stacked on one another for storage, then space is saved, but accessing items requires removing all baskets on top
Solution Approach 1:
The front wall is segmented into a removable door portion and a fixed frame portion. The door can be independently opened or removed, creating a segmented access mechanism that allows item retrieval without moving stacked baskets. This segmentation separates the access function from the containment function, enabling time-saving direct access while maintaining space-efficient stacking.
3Volume of moving object
If the front and rear walls are folded in half using a horizontal pivot, then the basket can be collapsed, but the folding sequence has inconsistent accuracy and increased complexity
Solution Approach 1:
The guide grooves in the left and right walls are merged with the upper frame structure, creating an integrated folding mechanism. This merging eliminates the need for separate pivot connections for the front and rear walls, as the upper frame's movement along the guide grooves automatically coordinates the folding of all walls simultaneously, reducing device complexity and improving folding accuracy.

AI summary
A foldable basket consisting of one bottom piece, one upper frame, one front wall, one rear wall, one left wall, and one right wall. The lower ends of the left and right walls are pivot-connected to the bottom piece. The upper ends of the front and rear walls are pivot-connected to the upper frame. The upper frame is located outside the left wall and the right wall, and can move up and down along the left wall and the right wall. The upper frame, the left wall and the right wall form as one body. The bottom piece, the front wall and the rear wall form as one body. There is a door installed on the front wall. The door downwards to reveal the interior of the foldable basket.
