Drawer Guide Clip Retention for Pull-Out Storage Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage systems, particularly those with metal wire or mesh baskets, lack versatility and ease of use, as they do not effectively prevent containers from being pulled out or deformed under heavy loads, leading to potential falls and structural issues.
Innovation Solution
A modular storage system incorporating a C-shaped clip that slideably attaches to a drawer frame guide, engaging with a container flange to prevent full withdrawal and deformation, enhancing user convenience and structural integrity by using injection molded plastic for both the container and clip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a container is made of metal wire or mesh basket, then it provides basic storage functionality, but it lacks versatility and ease of use, and does not prevent container falls or deformation under heavy loads
Solution Approach 1:
The storage system is divided into separate functional components: the container body, the flange, the clip, and the drawer frame guide. This segmentation allows each component to be optimized independently - the container for storage capacity, the flange for connection, and the clip for securing - thereby achieving both versatility and reliability simultaneously.
Solution Approach 2:
The flange acts as an intermediary element between the container and the clip connection system. It provides a dedicated attachment point that enables the clip to secure the container to the drawer frame guide, preventing falls and deformation while maintaining the container's structural integrity and versatility.
2Ease of operation
If a container is fully pullable out of the drawer frame, then ease of access is improved, but the container may fall out of the frame
Solution Approach 1:
The clip connection device enables dynamic interaction between the container and drawer frame. The container can be easily pulled out for access, but the clip maintains a secure connection that prevents complete removal or falling out, achieving both ease of operation and reliability through controlled mobility.
3Quantity of substance
If a container is provided with heavy load, then storage capacity is improved, but the container may deform
Solution Approach 1:
The clip is pre-attached to the drawer frame guide before the container is loaded. This preliminary securing action provides structural support and prevents deformation even when heavy loads are placed in the container, maintaining shape stability while preserving full storage capacity.
4Reliability
If a clip connection device is added to engage with container flange, then container retention and deformation prevention are improved, but device complexity increases
Solution Approach 1:
The clip connection device serves multiple functions simultaneously: it secures the container to prevent falling out, prevents deformation under heavy loads, and maintains ease of access. This multi-functionality achieves improved reliability without proportionally increasing system complexity, as a single component addresses multiple problems.

AI summary
A storage system comprising a drawer frame and one or more boxes. The drawer frame comprises first and second guides with a U-shaped cross section, which is open towards the interior of the drawer frame such that flanges of a box can be inserted into the guides to thereby support the box slideably in the drawer frame. Clips are attached slideably to the guides and engage with the box through a clip connection device interacting with a box connection device of the box, which prevents the box from falling out of the frame.
