Basket Drawer Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional basket drawers with two rollers on each rail face pulling resistance issues, occupy storage space, and have an unattractive appearance, making it difficult to load and pull the drawer smoothly.
Innovation Solution
A basket drawer structure featuring a peripheral rib with recessed portions and rotatably riveted first rollers on the basket, paired with second rollers on rail elements, allowing for smooth pulling without extending beyond the recessed portions, thus reducing space occupation and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two rollers are arranged on two rails respectively in a conventional cabinet, then the drawer can be pulled easily, but storage space is occupied and manufacture cost increases
Solution Approach 1:
The patent combines the functions of the drawer body and rollers into an integrated structure. The U-shaped rail is formed directly as part of the drawer body, eliminating the need for separate roller components and external rails. This merging reduces the number of parts, decreases storage space occupation, and lowers manufacturing costs while maintaining smooth drawer operation through the integrated rail design
2Ease of operation
If two rollers are arranged on two rails respectively in a conventional cabinet, then the drawer can be pulled easily, but manufacture cost increases
Solution Approach 1:
The patent merges the drawer body and rail structure into a single integrated component. The U-shaped rail is formed directly from the drawer body material, eliminating the need for separate roller components and external rail assemblies. This reduction in part count simplifies manufacturing processes, reduces assembly steps, and lowers overall production costs while maintaining smooth drawer operation
Solution Approach 2:
The drawer body serves multiple functions simultaneously: it provides structural support, forms the U-shaped rail for movement guidance, and integrates the roller function within its own structure. This multi-functionality eliminates the need for separate dedicated roller components and external rails, reducing manufacturing complexity and cost
3Reliability
If two rollers are arranged on two rails of the conventional cabinet, then the basket drawer can be supported, but the appearance becomes unattractive and the basket cannot be pulled easily when loaded
Solution Approach 1:
The patent integrates the support function into the drawer body itself through the U-shaped rail structure. This eliminates the need for externally visible separate rollers and rails, creating a clean, attractive appearance. The integrated design maintains reliable support and smooth pulling even when loaded, as the U-shaped rail provides continuous guidance and support along the drawer's movement path
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy pulling of the basket drawer with reduced effort while maintaining an attractive appearance and efficient use of space by integrating rollers within the recessed portions, enhancing the overall usability and aesthetics.
Implementation Method 1
two first rollers are rotatably riveted on the two recessed portions respectively... two second rollers are riveted on two front ends of the two support rails individually... the basket is supported and rolls by way of the two first rollers and the two second rollers

AI summary
A basket drawer structure contains: a basket and two rail elements. The basket includes a mesh, a holding space, an opening, and a peripheral rib. The peripheral rib has two recessed portions, two orifices, and two first rollers. The two recessed portions have two shaft holes, and two rivets insert through the two shaft holes to rivet with the two first rollers individually. The two rail elements are symmetrically fixed on a shelf or a cabinet. A distance between the two rail elements is equal to a width of the basket, and the two rail elements respectively include two support rails. Two second rollers are riveted on two front ends of the two support rails individually. The basket is retained in the two support rails by way of the peripheral rib, and the two second rollers of the two rail elements are mounted in the peripheral rib.
