Shelf for shoes and other articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable storage racks fail to securely retain shoes and other items, leading to falling issues due to movement and varying dimensions, especially when different-sized items are stored together.
Innovation Solution
A lightweight, compact, and portable storage rack design featuring a frame portion with vertically-oriented U-shaped supports and a liner portion with angled shelving components that attach to the frame, preventing items from falling by creating stable, angled shelves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable storage racks are designed to be lightweight and easy to move, then portability is improved, but the ability to securely retain shoes and items deteriorates
Solution Approach 1:
The storage rack is divided into a frame portion and a liner portion that can be separately assembled. The liner portion includes multiple shelving components that can be independently attached to the frame, allowing the structure to remain lightweight while providing secure retention through the combined system of frame and liner working together
Solution Approach 2:
The shelving components are configured with asymmetric features including front and back surfaces at different heights relative to the frame, creating angled shelves that naturally prevent items from falling forward. The front edge of each shelf is positioned lower than the back edge, forming a downward slope toward the front that secures items in place
2Ease of manufacture
If the storage rack uses simple horizontal shelves, then ease of manufacture is improved, but the ability to prevent items from falling deteriorates
Solution Approach 1:
Each shelving component is designed with an asymmetric profile where the front surface is positioned at a lower height than the back surface when attached to the frame. This creates a built-in angle that slopes downward toward the front, preventing shoes and items from falling off the front edge while maintaining a simple single-piece construction that is easy to manufacture
Solution Approach 2:
The shelving components utilize curved or angled surfaces rather than flat horizontal planes. The bottom surface of each shelving component is configured at an angle relative to the frame, creating a sloped configuration that naturally directs items toward the front while preventing them from falling off the back or sides
3Adaptability or versatility
If the storage rack accommodates shoes of different dimensions, then adaptability is improved, but the stability of items on shelves deteriorates
Solution Approach 1:
The liner portion is designed as a universal component that can accommodate various sizes and types of shoes through its multiple shelving components. The angled configuration of each shelf provides stable retention for different dimensional items, while the entire liner assembly can be attached to standard frame structures, making the system adaptable to different storage needs
Solution Approach 2:
The liner portion acts as an intermediary element between the frame structure and the shoes being stored. It provides the actual shelving surfaces that contact the items, while the angled configuration of the liner components creates stable positioning for shoes of different dimensions without requiring modifications to the frame structure
