Pivoting Support Arms for Compact Wall-Mounted Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted storage rack assemblies for bicycles and similar articles are limited by their fixed V-shaped configuration, which restricts their compactness during shipment, storage, and display, making them inefficient for consumer purchase and retail display.
Innovation Solution
A storage rack assembly with independently pivotal support arms arranged in an angular relationship, allowing for a compact configuration by folding and collapsing the arms for efficient storage, shipment, and display, while maintaining stable support for articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the support arms are configured in a fixed V-shaped unitary member, then the structural simplicity and ease of manufacture are improved, but the compactness during shipment and display deteriorates
Solution Approach 1:
The support arms are divided into separate, independently pivotal components rather than a fixed unitary member. Each support arm can pivot independently about its own pivot axis, allowing the assembly to be collapsed into a compact configuration for shipment and display while maintaining structural integrity during use.
Solution Approach 2:
The support arms are designed with pivotal movement capability, transitioning from a static fixed configuration to a dynamic adjustable configuration. This allows the rack assembly to change between an expanded functional state for supporting articles and a collapsed compact state for storage and shipment.
2Volume of moving object
If the support arms are made independently pivotal with respective pivot axes, then the compactness for shipment and display is improved, but the device complexity increases
Solution Approach 1:
The support arms are divided into separate, independently pivotal components rather than a fixed unitary member. Each support arm can pivot independently about its own pivot axis, allowing the assembly to be collapsed into a compact configuration for shipment and display while maintaining structural integrity during use.
Solution Approach 2:
The support arms can be positioned in nested or overlapping configurations when collapsed, with one arm fitting within or adjacent to the other, maximizing compactness while minimizing the increase in device complexity through efficient spatial arrangement.

AI summary
A wall-mounted storage rack assembly facilitates storage of articles such as bicycles, lawn care implements, tools, and the like by providing a pair of independently pivotally movable support arms, which are pivotally supported on an associated mounting bracket. The support arms are independently movable about respective pivot axes arranged in intersecting, angular relationship to each other, whereby in a lowered position of the support arms, they are arranged in a generally V-shaped, diverging orientation, while in a raised position of the support arms, they are positioned more closely together in a relatively compact configuration. By this compact configuration, efficient storage, shipment, and display for retail sales of the storage rack assembly is promoted.
