Hang standard and storage system including the hang standard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hang standards are not compatible with brackets having parallel attachment hooks, and they lack sufficient bending stiffness to support high loads while maintaining a visually appealing appearance.
Innovation Solution
The design incorporates protruding portions on either side of slots to create a recess, increasing bending stiffness through a double-layer sheet metal structure and optional features like longitudinal flanges and slanted inner walls, allowing for improved compatibility with various brackets and enhanced load-carrying capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If slots are recessed and obscured by protruding portions to achieve visual appeal, then appearance is improved, but compatibility with brackets having parallel attachment hooks deteriorates
Solution Approach 1:
The front face is segmented into multiple columns of slots, allowing different slot configurations in different columns. This enables compatibility with various bracket types (including those with parallel hooks) while maintaining the recessed design for visual appeal, as each column can be independently optimized for specific bracket configurations.
Solution Approach 2:
The hang standard is designed with universal compatibility features, including multiple slot columns and various connection point arrangements, enabling it to work with different bracket types (single-hook, parallel-hook, and other configurations) while preserving the aesthetically pleasing recessed appearance through strategic slot placement.
2Strength
If material thickness is increased to improve bending stiffness and load-carrying capacity, then strength is improved, but device complexity and material usage increase
Solution Approach 1:
Instead of increasing material thickness, the invention enhances bending stiffness by optimizing the geometric configuration in the lateral dimension. The protruding portions and recessed slots create a more efficient structural layout that resists bending forces without requiring additional material thickness, thus avoiding increased device complexity.
Solution Approach 2:
The hang standard features localized reinforcement through protruding portions positioned strategically at critical stress points. These protruding portions increase the second moment of area specifically where needed for bending resistance, rather than uniformly increasing the entire structure's thickness, thereby improving strength without proportionally increasing material usage.
3Strength
If protruding portions are added to increase bending stiffness, then load-carrying capacity is improved, but device complexity increases
Solution Approach 1:
The protruding portions serve multiple functions simultaneously: they increase the second moment of area for bending stiffness, provide structural support for the recessed slots, and create the aesthetic recessed appearance. By merging these functions into a single structural feature, the invention improves load-carrying capacity without proportionally increasing device complexity.

AI summary
A hang standard, for mounting vertically and connecting with cantilevered brackets, is elongated and has an approximately U-shaped cross-section with a front portion and two rearwards extending leg portions. The front portion comprises a plurality of slots located in a recess between first and second protruding portions, which are located on first and second side of the slots. The recess is laterally continuous from the first to the second protruding portion and over two columns of slots.
