Reversible Shelf Beam Layout for Configurable Edge Lips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shelving systems require multiple, often unused, shelves to achieve various configurations, increasing costs and complexity due to the need for different shelf structures to accommodate different applications, whereas a solution is needed to provide adjustable shelf configurations using common components without additional shelves.
Innovation Solution
A shelving apparatus with identical shelves and reversible beams that can be oriented in different ways to create various configurations, defining upstanding lips along shelf edges without requiring extra shelves, by using common but reversible beams and columns to support the shelves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different shelf structures are provided to achieve various configurations, then the versatility of shelf configurations is improved, but the device complexity and quantity of components increase
Solution Approach 1:
The beam is designed with a universal structure that can perform multiple functions: it can be oriented in different directions to create lips at different edges, and it can support shelves in various configurations. This single multi-functional beam replaces what would traditionally require multiple specialized beams or shelves for different configurations.
Solution Approach 2:
Instead of modifying the shelf structure to create lips, the invention inverts the approach by using the beam orientation to define the lip configuration. The beam can be installed in different orientations (e.g., with the flange facing different directions) to create lips at different edges, thereby achieving configuration variety without changing the shelf itself.
2Adaptability or versatility
If multiple different shelf structures are provided to achieve various configurations, then the versatility of shelf configurations is improved, but the cost increases
Solution Approach 1:
The beam serves multiple purposes: it provides structural support, defines shelf edges, creates lips when needed, and enables various configurations. This multi-functionality reduces the total number of components needed, as the same beam type can be used in all configurations rather than requiring specialized components for each scenario.
Solution Approach 2:
The invention combines the functions of multiple potential components (different beam types, different shelf types with and without lips) into a single universal beam design that achieves all configurations through orientation variations, thereby reducing the quantity of parts required.
3Adaptability or versatility
If multiple different shelf structures are provided to achieve various configurations, then the versatility of shelf configurations is improved, but the ease of manufacture decreases
Solution Approach 1:
The beam is manufactured as a single universal component with standardized dimensions and features that can serve all configuration needs. This universality simplifies the manufacturing process compared to producing multiple specialized beam or shelf variants, as it requires only one tooling set and production line configuration.
Solution Approach 2:
The beam incorporates localized features (such as a flange at a specific position) that enable lip formation when needed, while the rest of the beam maintains a simple, easy-to-manufacture structure. This allows the beam to provide configuration variety through orientation rather than requiring complex features throughout the entire component.
