Metal shelf with a connection structure of two opposite slide rails for drawer basket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal shelves face issues with objects easily dropping from holding plates due to lack of stop ribs, limited accommodation space, and cumbersome screw-based connections that restrict the use of drawer baskets to a single size.
Innovation Solution
A connection structure featuring two opposite slide rails with fixers and fixing sheets that allow drawer baskets to be hung securely on holding plates, with adjustable distances between fixers to accommodate baskets of varying sizes, and a coupling column for secure movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw bolts are used to connect holding plates to the metal shelf, then the connection is secure, but the connection process becomes troublesome and time-consuming
Solution Approach 1:
The connection structure is divided into separate modular components: fixing sheets attached to holding plates, and fixers mounted on the metal shelf. This segmentation allows independent installation and adjustment of each component, eliminating the need for time-consuming screw assembly while maintaining secure connection through the interlocking design of fixing sheets and fixers.
Solution Approach 2:
The fixing sheets and fixers are designed to self-align and self-lock into position without requiring external fastening tools. The fixing sheets have engagement features that automatically mate with corresponding features on the fixers, enabling quick installation and adjustment while ensuring reliable connection security.
2Ease of manufacture
If fixers are designed for a sole size of drawer baskets, then the connection is simple, but the adaptability to different basket sizes is limited
Solution Approach 1:
The fixers are designed with adjustable positioning capabilities, allowing their location and orientation to be modified according to different drawer basket sizes. The fixing sheets can be repositioned on the holding plates, and the fixers can be adjusted on the metal shelf, enabling the same connection structure to accommodate various basket dimensions while maintaining simple installation procedures.
Solution Approach 2:
The connection structure using fixing sheets and fixers serves multiple functions: it can accommodate different drawer basket sizes, allow easy installation and removal, and provide adjustable positioning. This universal design enables a single connection system to handle various storage needs without requiring multiple specialized components.
3Device complexity
If objects are placed only on holding plates, then the structure is simple, but the accommodation space is limited
Solution Approach 1:
The storage system is segmented into multiple functional layers: holding plates for stationary items and drawer baskets for movable items. This segmentation allows the system to utilize vertical space more effectively, providing additional accommodation volume without complicating the overall structure, as each layer serves a specific storage purpose.
Solution Approach 2:
The system transitions from two-dimensional placement on holding plates to three-dimensional utilization by adding drawer baskets that can be pulled out. This dimensional change significantly increases the accessible storage volume while maintaining structural simplicity through the use of standard drawer basket components that integrate with the existing shelf framework.
