Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cantilever racks are prone to arm dislodgement and bending moments, leading to reduced holding capacity and requiring substantial floor space for stability, making them cumbersome and limited in use.
Innovation Solution
A wall-mountable storage system featuring S-shaped uprights with mounting and bracket flanges, angled brackets for enhanced load retention, and couplers for secure fastening to the wall, reducing bending moments and eliminating the need for extensive floor space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cantilever racks use arms that extend outward from a support, then objects can be stored on the arms, but the arms are easily dislodged when objects are removed
Solution Approach 1:
The rack is divided into separate modular components: uprights, arms, and base units that can be independently assembled and disassembled. Each arm is a separate component that attaches to uprights through standardized connection points, allowing easy removal while maintaining stability through proper attachment mechanisms.
Solution Approach 2:
The rack transitions from traditional floor-standing cantilever design to a wall-mounted configuration, utilizing the vertical wall surface rather than floor space. This dimensional change repositions the support structure from the floor to the wall, fundamentally altering how loads are distributed and stabilized.
2Strength
If cantilever racks are designed with substantial bases to resist bending moments, then holding capacity increases, but the racks require significant open floor space
Solution Approach 1:
The rack system relocates the primary support structure from the floor to the wall, utilizing vertical wall space instead of horizontal floor space. This transfers the load-bearing function to the wall mounting, eliminating the need for substantial floor-based bases while maintaining structural integrity through wall anchoring.
Solution Approach 2:
The substantial base component is extracted and removed from the design. Instead of using large floor-based bases for stability, the system relies on wall-mounted uprights that provide structural support and resistance to bending moments through their wall anchoring, eliminating the need for extensive floor space occupation.
3Stability of the object's composition
If cantilever racks use traditional floor-standing construction, then stability against bending moments is achieved, but the racks are cumbersome and limited in use
Solution Approach 1:
The rack system moves from horizontal floor-based support to vertical wall-based support, fundamentally changing the structural configuration. This allows the rack to be installed in locations where floor space is limited or unavailable, significantly increasing installation flexibility and adaptability to different environments while maintaining stability through wall anchoring.
Solution Approach 2:
The rack is constructed from modular segmented components (uprights, arms, base units) that can be independently positioned and configured. This modularity allows flexible installation in various locations and configurations, adapting to different space constraints and usage requirements while maintaining structural stability through standardized connection mechanisms.

AI summary
A wall-mountable storage system, comprising a plurality of uprights having a mounting flange, an extending surface and a bracket interfacing flange, each upright having a plurality of openings spaced each of the mounting flange, the bracket interfacing flange and the extending surface for mounting the system to a wall, accepting passage of the brackets through the uprights, and mounting the brackets to the uprights, respectively. The configuration and load application of the system may increase the sheer component of loading on the system and decrease the bending moment component, thereby increasing the maximum load capacity of the system.
