Basket Assembly with Twist-Lock Connecting Posts for Adjustable Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basket assemblies with snap connections face difficulties in releasing and replacing connecting posts, making it complicated to adjust the distance between the main basket and extension part, limiting adaptability to different object sizes.
Innovation Solution
The use of twist locks in socket recesses of both the main basket and extension part allows for easy locking and unlocking of connecting posts by simple twisting, enabling easier replacement and adjustment of the assembly's height without the need for tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If snap connections are used to anchor connecting posts in socket recesses, then the connecting posts can be fastened securely, but they can be released only with difficulty and replacing them is relatively complicated
Solution Approach 1:
The connecting post is designed with a twistable portion that can rotate between a locked position (where the protrusion engages the socket recess) and an unlocked position (where the protrusion disengages). This dynamic twisting motion allows easy release and replacement while maintaining secure fastening during the locked state.
Solution Approach 2:
The connecting post is divided into functionally distinct portions: a fastening portion with a protrusion for engagement, a twistable portion for operation, and a support portion for structural integrity. This segmentation allows the twistable portion to be optimized for easy manipulation while other portions maintain securing functionality.
2Stability of the object's composition
If the basket assembly uses fixed connecting posts, then the structure is stable, but the total height cannot be adapted to different object sizes
Solution Approach 1:
The connecting posts are designed to be replaceable with different lengths. The twistable mechanism allows easy removal and replacement of connecting posts, enabling the basket assembly's total height to be adjusted by selecting appropriate connecting post lengths for different storage needs while maintaining structural stability when locked.
Solution Approach 2:
The socket recesses and twistable mechanism serve as a universal interface that accommodates connecting posts of various lengths. This allows the same basket assembly structure to be adapted for different object sizes by simply changing the connecting post length, providing multi-functionality without redesigning the entire assembly.

AI summary
A basket assembly having a main basket (1) and an extension part (2) and connecting posts (3). The main basket (1) has a basket base (4) and side walls (5) and socket recesses (6, 7) for the connecting posts (3) are formed in each case in the side walls (5) and in the extension part (2). The extension part (2) is fastened or is fastenable on the main basket (1), at a distance from the main basket (1), by the connecting posts (3) locked releasably in the socket recesses (6, 7), and the connecting posts (3) are each releasably locked or lockable in one of the socket recesses (6) of the side walls (5) of the main basket (1) by a twist lock (8), and are each releasably locked or lockable in one of the socket recesses (7) of the extension part (2) by a twist lock (8).
