Solution Overview

Problem

Existing drawer assemblies suffer from inefficient use of storage space during transport due to non-optimal folding methods that increase the risk of damage and require additional components, leading to inconsistent dimensions and increased thickness, which complicates transport and assembly.

Innovation Solution

A drawer assembly with hinge-connected drawer base segments that allow for additional folding, ensuring a compact and stable transport position while protecting sensitive surfaces, and can be assembled without tools, using flexible layers like film hinges or adhesive layers for connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If the drawer back panel is folded towards the drawer base using a hinge, then storage space is reduced, but the hinge extension causes the drawer back panel to bend in the folding region, increasing damage risk

Engineering Contradiction:

Improvestorage spaceVSAvoiddamage risk

Core Design Contradiction:

Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The drawer base is divided into multiple segments (first drawer base segment and second drawer base segment) that can fold relative to each other. This segmentation allows the assembly to achieve compact storage volume while distributing the folding action across multiple joints, reducing stress concentration and bending damage risk in any single region.

Inventive Principle:

Principle #1Segmentation

2Volume of stationary object

If traditional folding methods are used, then storage space is reduced, but the thickness of the folded furniture part increases significantly, impairing stacking

Engineering Contradiction:

Improvestorage spaceVSAvoidthickness

Core Design Contradiction:

Volume of stationary objectVSLength of stationary object

Solution Approach 1:

The drawer base segments and drawer back panel are arranged in a nested configuration during folding, where components are positioned within the footprint of larger components. This nesting approach minimizes the overall thickness of the folded assembly, enabling efficient stacking while achieving compact storage volume.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Stability of the object's composition

If fixing means are used to prevent sub-segments from spreading apart, then transport stability is improved, but the material of sub-segments is bent or stressed even more in the bending region

Engineering Contradiction:

Improvetransport stabilityVSAvoidstress on material

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The drawer base segments and drawer back panel are pre-configured with hinge connections that maintain structural integrity during transport. The segments are arranged to naturally resist spreading apart through their geometric configuration and connection points, eliminating the need for additional fixing means that would increase stress on the material.

Inventive Principle:

Principle #10Preliminary action

4Volume of stationary object

If multiple folds are used to achieve compact transport position, then storage space is reduced, but the number of components increases and assembly becomes more complex

Engineering Contradiction:

Improvestorage spaceVSAvoidnumber of components

Core Design Contradiction:

Volume of stationary objectVSDevice complexity

Solution Approach 1:

The hinge connections are integrated directly into the drawer base segments and drawer back panel as integral parts, rather than being separate components. This merging of functions reduces the total number of components while maintaining the multiple-fold capability needed for compact storage, simplifying both the assembly and disassembly processes.

Inventive Principle:

Principle #5Merging (Combining)
