Telescopic basket with steplessly-adjustable width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic storage baskets have uneven bottoms and insufficient connection firmness due to their fixed structure, which limits their adaptability to different cabinet sizes and results in unstable placement of items.
Innovation Solution
A telescopic basket with a steplessly-adjustable width is designed, featuring two sets of basket frames and nets in a telescopic and staggered connection, with guiding iron wires and positioning frames that allow for even expansion and contraction, ensuring a stable and even bottom and reliable connection through a fixing and connecting part system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the left and right baskets are telescopically connected through plastic fixing part and plastic connecting part, then the basket can be adjusted to fit cabinets of different sizes, but the connection stability is insufficient
Solution Approach 1:
The patent combines multiple connection mechanisms (plastic fixing part, plastic connecting part, and wire clamping structure) into a unified telescopic connection system. The wire clamping structure integrates with the plastic components to create a composite connection system that provides both adjustability and stability, resolving the contradiction between adaptability and connection reliability.
Solution Approach 2:
The connection system uses composite construction combining plastic materials (fixing part and connecting part) with metal wire elements. This composite approach leverages the advantages of both materials: plastic provides flexibility and ease of adjustment, while wire clamping provides structural strength and connection stability, thereby improving both adaptability and reliability simultaneously.
2Device complexity
If the iron wires at the bottom of the left and right baskets are arranged longitudinally and just stacked, then the structure is simple, but the bottom becomes uneven during expansion and contraction
Solution Approach 1:
The patent implements a nested arrangement where the iron wires of one basket are positioned within or alongside the wires of the other basket in a staggered pattern. This nesting ensures that during telescopic expansion and contraction, the wires interlock and support each other, maintaining bottom evenness while adding minimal structural complexity.
Solution Approach 2:
Instead of simple longitudinal stacking in one dimension, the patent introduces a staggered arrangement that utilizes both longitudinal and transverse positioning dimensions. This two-dimensional wire arrangement ensures continuous contact and support between the baskets' bottoms, preventing unevenness during movement while keeping the structure relatively simple.
3Device complexity
If the left and right baskets are not connected at the bottom, then the structure is simpler, but the firmness of the bottom is insufficient
Solution Approach 1:
The patent introduces wire clamping structures as intermediary elements at the bottom connection points between the left and right baskets. These wire clamps act as mediators that provide localized reinforcement and connection where needed, enhancing bottom firmness without requiring a complete bottom connection system that would add significant structural complexity.
Solution Approach 2:
Instead of uniformly connecting the entire bottom structure, the patent applies localized wire clamping at specific critical points where the baskets meet. This local quality approach provides sufficient firmness and support at key locations while maintaining overall structural simplicity, avoiding the need for complex full-bottom connection systems.

AI summary
A telescopic basket with steplessly-adjustable width includes a basket main body, a fixing part, and a connecting part. The basket main body includes two sets of basket frames and a basket bottom. The two sets of basket frames are arranged opposite to each other. The basket bottom includes two sets of nets. The two sets of nets are telescopically and staggeredly with each other. The two sets of basket frames are telescopically connected to the two sets of nets through the fixing part and the connecting part, respectively.
