Solution Overview

Problem

Existing support assemblies for wire shelving units often interfere with the shelving unit's use, require additional tools for installation and removal, and are costly to produce, with plastic elements prone to warping during molding.

Innovation Solution

A spring-actuated telescoping column with a receiving collar that engages upper and lower shelf wire members, allowing for secure attachment without tools and reduced material usage through rib elements for improved tolerance and cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing support assemblies are mounted on wire shelving units, then additional storage options are provided, but the accessories interfere with shelving unit use and impede access to the front of the shelving area

Engineering Contradiction:
Improvestorage optionsVSAvoidaccess to shelving unit
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support assembly is nested within the front wire members of the shelving unit, with the telescoping column fitting inside the receiving collar. This nesting arrangement allows the support to be mounted on the shelving unit without extending into the top shelving area, thus providing additional storage options while maintaining easy access to the front of the shelving unit.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If existing accessories with multiple-element structures are used, then additional storage functionality is achieved, but separate fasteners and tools are required for installation and removal

Engineering Contradiction:
Improvestorage functionalityVSAvoidinstallation process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support assembly merges the support function and attachment function into a single integrated structure. The telescoping column with receiving collar combines the support element and fastening mechanism, eliminating the need for separate fasteners and tools. The spring mechanism is integrated within the telescoping column, allowing the entire assembly to be installed and removed by hand without additional tools.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If plastic elements are formed with reduced amounts of material, then production costs are reduced, but the elements may warp during cooling steps after molding

Engineering Contradiction:
Improveproduction costVSAvoidelement warping
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The receiving collar is designed with non-uniform wall thickness, having a first wall thickness at the top portion and a second wall thickness at the bottom portion. This local variation in quality allows different sections of the plastic element to cool at different rates during molding, compensating for warping tendencies while using reduced amounts of material to lower production costs.

Inventive Principle:
Principle #3Local quality

4Quantity of substance

If given solid plastic elements are made uniformly thin, then material usage is reduced, but warping risk increases during cooling

Engineering Contradiction:
Improvematerial usageVSAvoidwarping risk
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

Instead of making the plastic element uniformly thin throughout, the receiving collar features localized thickness variations with a first wall thickness at the top and a second wall thickness at the bottom. This allows material reduction in certain areas while maintaining sufficient thickness in other areas to prevent warping during cooling, optimizing both material usage and structural stability.

Inventive Principle:
Principle #3Local quality

5Strength

If close fit tolerance is used between sliding elements, then structural integrity is improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing tolerance
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The telescoping column is designed to slide within the receiving collar with a dynamic fit that provides sufficient structural integrity without requiring extremely tight tolerances. The spring mechanism and telescoping action allow for controlled movement and adjustment, maintaining strength while facilitating easier manufacturing with reasonable tolerances.

Inventive Principle:
Principle #15Dynamics

AI summary

A support adapted for mounting to wire shelving units, particularly a support adapted to be securely coupled and repositioned on upper and lower horizontally-extending wire members located at the front of wire shelving units. The support does not interfere with use of a shelving unit including the storage of items on the shelving unit or handing items under the shelving unit.
