Solution Overview

Problem

Existing stackable and collapsible containers face issues with complex assembly/disassembly, low rigidity, and increased transport costs due to volume inefficiency when empty, particularly when transporting perishable goods like fish.

Innovation Solution

A container design featuring a lower base, upper frame, and side walls with rapid disassembly means using angular uprights, tabs, and screws, along with ventilation holes and evacuation orifices, which eliminates the need for a top lid, allowing for nesting during transport and maintaining structural rigidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If containers are transported empty without disassembly, then transport time is reduced, but transport volume efficiency deteriorates (containers occupy more space)

Engineering Contradiction:

Improvedisassembly timeVSAvoidtransport volume

Core Design Contradiction:

Loss of timeVSVolume of moving object

Solution Approach 1:

The container is designed to nest within another container of the same type. The open-top configuration allows one container to be placed inside another, reducing transport volume from 2 separate containers to the volume of 1 container when transporting empty containers back to the processing center.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If containers are designed with rapid disassembly means, then ease of operation improves, but structural rigidity deteriorates

Engineering Contradiction:

Improveassembly speedVSAvoidstructural rigidity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The container is divided into separate modular components (base, side walls, front wall, back wall, upper frame) that can be quickly assembled and disassembled using simple connecting means such as screws and holes, while maintaining structural integrity when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The container uses composite construction with wooden or plastic walls reinforced with metal frames and corner protectors, combining materials to achieve both ease of assembly and structural rigidity.

Inventive Principle:

Principle #40Composite materials

3Adaptability or versatility

If the container has an open top without lid, then stackability improves, but protection of goods deteriorates

Engineering Contradiction:

ImprovestackabilityVSAvoidcontamination risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The container transitions from a closed configuration (when in use) to an open configuration (when stacked for transport). The open-top design allows easy loading/unloading during processing and enables nesting when empty, while the robust frame structure provides sufficient protection during transport.

Inventive Principle:

Principle #15Dynamics

4Productivity

If containers are stacked without disassembly, then productivity improves, but ventilation efficiency deteriorates

Engineering Contradiction:

Improvetransport efficiencyVSAvoidair stagnation

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The container walls incorporate ventilation holes that allow air circulation through the container walls. When containers are stacked, ventilation continues through the side walls, preventing complete air stagnation and maintaining some airflow for perishable goods.

Inventive Principle:

Principle #31Porous materials
