Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wall racks lack versatility in accommodating both wider and narrower items efficiently, as they often require separate configurations or adjustments, which can be cumbersome and inefficient.

Innovation Solution

A wall rack design featuring mountable brackets with pivotable extensions that can be deployed to support wider items and stored within the arm to accommodate narrower items, utilizing a yoke section with stop surfaces and channels for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional wall racks use fixed arm configurations, then the structure is simple and stable, but the rack cannot accommodate items of varying widths efficiently

Engineering Contradiction:

Improveaccommodation of varying item widthsVSAvoidrack structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the arm extensions pivotable rather than fixed. The extensions can rotate between a deployed position (supporting wider items) and a stored position (accommodating narrower items), transforming a static structure into a dynamic one that adapts to different storage needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the arm structure into multiple components: a fixed arm portion and a separate pivotable extension portion. This segmentation allows the extension to be independently positioned and stored, enabling the rack to adjust its effective width without requiring complete structural reconfiguration.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If separate rack configurations are used for wider and narrower items, then item support is optimized, but the device requires multiple configurations and adjustments

Engineering Contradiction:

Improvesupport for different item sizesVSAvoidconfiguration adjustment convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The pivotable extension provides a dynamic, single-configuration solution where the extension automatically adjusts between supporting wider and narrower items through simple rotation. This eliminates the need for multiple fixed configurations or complex adjustment mechanisms, improving ease of operation while maintaining adaptability.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the rack is designed for wider items, then larger items are supported, but space efficiency for narrower items is reduced

Engineering Contradiction:

Improvesupport for wider itemsVSAvoidspace efficiency

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

By segmenting the arm into fixed and pivotable extension portions, the rack can dynamically adjust its occupied space. When storing narrower items, the extension pivots to a stored position, reducing the effective width and improving space efficiency while maintaining the capability to support wider items when needed.

Inventive Principle:

Principle #1Segmentation
