Solution Overview

Problem

Existing storage assemblies lack adjustable and versatile solutions for accommodating uneven floor surfaces and ensuring proper fitting and accessibility of slide-out storage components, which can lead to instability and usability issues.

Innovation Solution

The storage assembly incorporates an adjustable faceplate and caster assemblies that can be vertically adjusted, allowing the slide-out storage assembly to be securely positioned on uneven floors and ensuring proper alignment with the storage cabinet, with features like adjustable mounting brackets and pivoting connections for enhanced stability and accessibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed storage assembly is used, then the structure is simple and stable, but it cannot accommodate uneven floor surfaces and lacks adjustability

Engineering Contradiction:
Improveadaptability to uneven floor surfacesVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage assembly incorporates adjustable caster assemblies that enable dynamic positioning and height adjustment of the slide-out storage component. The casters can be individually adjusted to accommodate uneven floor surfaces, transforming a static structure into a dynamically adaptable system that maintains stability across varying conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention utilizes vertically adjustable casters that change the height parameter of the storage assembly to adapt to uneven floors. The adjustable faceplate also changes angular parameters to ensure proper alignment, allowing the system to maintain functionality across different floor conditions without requiring complete structural redesign.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a slide-out storage assembly is added to a storage cabinet, then accessibility is improved, but stability on uneven floors deteriorates without adjustment mechanisms

Engineering Contradiction:
Improveaccessibility of storage contentsVSAvoidstability on uneven floors
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjustable caster assemblies allow the slide-out storage component to dynamically adapt its position and orientation based on floor conditions. This dynamic adjustment capability ensures that the slide-out mechanism remains stable and accessible even when the storage cabinet is placed on uneven surfaces.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustable casters are designed to be individually adjusted to level the storage assembly on uneven floors. This self-adjustment capability allows the system to automatically compensate for floor irregularities, maintaining stability and accessibility without requiring external intervention or complex stabilization systems.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If adjustable caster assemblies are integrated into the base assembly, then adaptability to floor conditions is improved, but device complexity increases

Engineering Contradiction:
Improveadjustability to floor conditionsVSAvoidbase assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base assembly is segmented into multiple independently adjustable caster units rather than a single fixed support structure. Each caster can be individually adjusted, allowing the system to adapt to uneven floors through distributed adjustment points. This segmentation provides adaptability while keeping each individual caster component relatively simple in design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustable caster assemblies serve multiple functions: they provide mobility, height adjustment, and leveling capability for the storage assembly. By integrating these multiple functions into a single component, the invention reduces overall device complexity compared to using separate mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A storage assembly includes a storage cabinet having an interior space and a slide-out storage assembly operable between open and closed positions relative to the storage cabinet. The slide-out storage assembly includes a base assembly having one or more integrally formed mounting brackets formed thereon. One or more caster assemblies are mounted to the one or more integrally formed mounting brackets of the base assembly of the slide-out storage assembly. The one or more caster assemblies are vertically adjustable along the one or more integrally formed mounting brackets of the base assembly. The slide-out storage assembly further includes a faceplate coupled to the base assembly and adjustably associated with the storage cabinet.
