Solution Overview

Problem

Existing plastic storage boxes are not easily disassembled, have poor load-bearing capacity, are prone to water penetration, and lack flexible opening options, making them inconvenient and inefficient for storage and use.

Innovation Solution

An assemblable storage box design featuring detachable side plates with positioning fasteners, a rotatable box cover connected via a shaft core, and side wings to prevent water ingress, along with a flexible connection belt for adjustable opening angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If storage boxes are made as single integral pieces of plastic, then manufacturing is simple and inexpensive, but they cannot be collapsed for storage and are difficult to assemble from separate parts

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcollapsibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The storage box is divided into multiple separate components: a base portion, a removable insert with dividers, and a lid. These segments can be manufactured independently using simple plastic molding processes, then assembled together. The insert itself is segmented into multiple divider sections that can be rearranged. This segmentation enables both ease of manufacture and adaptability, as the separate parts can be collapsed or disassembled for storage while maintaining simple production methods.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If storage boxes use separate assembled parts, then they can be collapsed and stored, but assembly becomes complex and time-consuming

Engineering Contradiction:
ImprovecollapsibilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functional elements into integrated components. The insert assembly combines side walls, bottom sections, and divider elements into a single molded piece that acts as a unified unit. The lid integrates handle portions and closing mechanisms into one component. This merging reduces the number of separate parts that need assembly while maintaining collapsibility, as the integrated components can be folded or collapsed as single units rather than requiring assembly of numerous small parts.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If storage boxes have fixed dividers, then manufacturing is simple, but the dividers cannot be removed or repositioned to accommodate different items

Engineering Contradiction:
Improvedivider manufacturingVSAvoiddivider repositionability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The divider system transitions from static to dynamic functionality. The insert is designed with movable divider sections that can be shifted along tracks or guides within the insert structure. The dividers can be repositioned to different locations or removed entirely, allowing the storage configuration to adapt to different item sizes and shapes. This dynamic design maintains relatively simple manufacturing, as the movement mechanism uses basic geometric features molded into the plastic components rather than complex mechanical assemblies.

Inventive Principle:
Principle #15Dynamics

AI summary

An assembled storage box. A body (10) thereof comprises a bottom plate (11) and four side plates (12) for the front, back, left and right sides, respectively. Two adjacent side plates (12) are detachably engaged with each other. The bottom of each of the four side plates (12) is provided with a support platform (121). Each of the four sides of the bottom plate (11) extends outward in the horizontal direction to form a position-fixing edge (111) respectively. The position-fixing edges (111) at the four sides of the bottom plate (11) are attached to and placed on the support platforms (121) of the four side plates (12) respectively. As the two adjacent side plates (12) are detachably engaged with each other and the position-fixing edges (111) at the four sides of the bottom plate (11) are attached to and placed on the support platforms (121) of the side plates (12), the assembly and disassembly of the storage box is convenient and fast. The side plates (12) and the bottom plate (11) can be stacked together for storage, significantly reducing the occupied space.
