Plastic drawer

Solution Overview

Problem

Existing plastic drawers are prone to deformation during use and cannot be easily disassembled, leading to wasteful scrapping when one side deforms.

Innovation Solution

A plastic drawer design featuring a base plate with clamping slots and uniformly distributed clamping columns, combined with a protective component comprising side plates, metal reinforcing ribs, and connecting components with T-shaped clamping blocks and disassembling plates, allowing for enhanced strength and easy disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the plastic drawer is made as an integral structure, then the manufacturing process is simple, but the drawer deforms during use and cannot be disassembled for repair

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoiddisassembly capability

Core Design Contradiction:

Ease of manufactureVSEase of repair

Solution Approach 1:

The drawer is divided into multiple independent components including the drawer body, side plates, back plate, bottom plate, and reinforcing ribs. These segments can be manufactured separately and assembled together, enabling both simplified manufacturing of individual parts and easy disassembly for repair by separating the components through the connecting components with T-shaped clamping blocks.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the plastic drawer is made as an integral structure, then the manufacturing process is simple, but the drawer structure has low strength and is prone to deformation

Engineering Contradiction:

Improvemanufacturing process simplicityVSAvoidstructural strength

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The drawer combines plastic materials for the drawer body with metal materials for the reinforcing ribs and connecting components. This composite structure leverages the corrosion resistance and formability of plastics along with the high strength and rigidity of metals, creating a drawer that is both easy to manufacture and resistant to deformation during use.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The drawer is divided into multiple independent components including the drawer body, side plates, back plate, bottom plate, and reinforcing ribs. These segments can be manufactured separately and assembled together, enabling both simplified manufacturing of individual parts and easy disassembly for repair by separating the components through the connecting components with T-shaped clamping blocks.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the drawer deforms during use, then the structural integrity is compromised, but the integral structure cannot be disassembled leading to wasteful scrapping

Engineering Contradiction:

Improvestructural integrityVSAvoidmaterial waste

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The drawer is divided into multiple independent components including the drawer body, side plates, back plate, bottom plate, and reinforcing ribs. These segments can be manufactured separately and assembled together, enabling both simplified manufacturing of individual parts and easy disassembly for repair by separating the components through the connecting components with T-shaped clamping blocks.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular design with detachable connecting components allows damaged parts to be identified and replaced individually while retaining functional components. This enables recovery and continued use of undamaged parts, reducing material waste compared to discarding the entire integral drawer when one component deforms.

Inventive Principle:

Principle #34Discarding and recovering
