Adjustable drawer

Solution Overview

Problem

Cabinets with drawers require customized widths and lengths due to varying space availability, leading to inconsistent drawer sizes and limited adaptability.

Innovation Solution

An adjustable drawer with movable connecting elements that allow for expansion or contraction in both width and length directions, utilizing sliding rails and fasteners to adjust the drawer body's dimensions to fit various cabinet sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If drawers are customized to match different cabinet sizes, then the fit and adaptability are improved, but the manufacturing complexity and cost increase

Engineering Contradiction:

Improvedrawer adaptabilityVSAvoidcustomization complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The drawer body is divided into multiple connecting elements that can be independently adjusted. These elements include side walls with adjusting mechanisms, allowing the drawer to be segmented and reconfigured to match different cabinet dimensions without requiring complete customization of the entire drawer structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drawer incorporates movable connecting elements with adjusting mechanisms that allow dynamic modification of drawer dimensions. The side walls can be moved along guide rails or tracks, enabling the drawer to adapt to different spaces while maintaining a relatively simple base structure that doesn't require full customization for each application

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If fixed-size drawers are used, then the manufacturing process is simplified, but the adaptability to different cabinet spaces is reduced

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoiddrawer adaptability

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The drawer incorporates movable connecting elements with adjusting mechanisms that allow dynamic modification of drawer dimensions. The side walls can be moved along guide rails or tracks, enabling the drawer to adapt to different spaces while maintaining a relatively simple base structure that doesn't require full customization for each application

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The drawer design uses standardized connecting elements and adjusting mechanisms that can be universally applied across different drawer configurations. This allows a single base design to serve multiple cabinet sizes and types, eliminating the need for completely different drawer structures for each application

Inventive Principle:

Principle #6Universality (Multi-functionality)
