Solution Overview

Problem

Existing storage containers are inefficient in terms of space utilization and shipping costs due to fixed sizes that do not match the amount of storage materials, leading to wasted space or the need for additional containers.

Innovation Solution

A modular container system comprising a base, lid, end modules, intermediate expansion modules, and latch modules that allow for expansion and reduction in size, enabling flexible storage capacity and efficient shipping by disassembling components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a fixed-size container is used, then the container structure is simple and easy to manufacture, but space utilization is poor and additional containers are needed when storage materials do not match the container size

Engineering Contradiction:
Improvecontainer structure simplicityVSAvoidstorage capacity flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The container is divided into a base and multiple interchangeable modules (end modules and intermediate modules) that can be assembled in different configurations. This segmentation allows the container to be customized for different storage needs while maintaining manufacturing simplicity through standardized components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized modules are designed to be universally compatible, allowing the same end modules and intermediate modules to be used in various container configurations. This multi-functionality enables a single set of components to serve multiple storage capacity requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional containers are used to match storage needs, then storage capacity flexibility is improved, but the number of containers increases and space is wasted

Engineering Contradiction:
Improvestorage capacity flexibilityVSAvoidnumber of containers
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Instead of using multiple separate containers, the invention segments a single container into modular sections that can be assembled in different quantities. This reduces the total number of containers needed while maintaining the ability to adjust storage capacity to match actual storage requirements.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If empty assembled containers are shipped, then the container is ready for immediate use, but shipping costs and space utilization are inefficient

Engineering Contradiction:
Improvereadiness for useVSAvoidshipping cost and space efficiency
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The container system is segmented into separable modules that can be shipped in a disassembled state, reducing shipping volume and costs. The modules are designed for easy assembly at the destination, maintaining operational readiness while improving shipping efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are pre-designed and pre-configured with standardized connection interfaces, allowing for rapid assembly at the destination without requiring complex preparation or specialized tools, thus maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action
