Nested Multi-Compartment Storage Unit with Removable Insulated Liner

Solution Overview

Problem

There is a need for a portable storage unit that is lightweight, secure, waterproof, and capable of maintaining temperature-sensitive items, while also providing over-the-shoulder carrying functionality.

Innovation Solution

A multi-component portable storage unit comprising an external and internal component, where the internal component is removably attachable to the external component via snaps, buttons, or clips, constructed from waterproof materials like polyamide and polyvinyl chloride, with sealed compartments and optional insulation for temperature control, and equipped with straps for carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If the portable storage unit uses flexible collapsible compartments for lightweight and portable features, then the weight and portability are improved, but the security and waterproof protection are compromised

Engineering Contradiction:

ImproveweightVSAvoidsecurity and waterproof protection

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The storage unit is divided into multiple separate compartments (first compartment, second compartment, third compartment) with distinct functions. The first and second compartments form a nested structure that can be separated, while the third compartment provides additional storage. This segmentation allows each compartment to be optimized for specific purposes (waterproof storage, insulated storage, general storage) while maintaining overall portability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs different materials for different compartments to address both lightweight requirements and protection needs. The first compartment uses waterproof material, the second compartment uses insulated material, and the third compartment uses lightweight material. This composite material approach allows each section to provide its specific protective function while keeping the overall unit lightweight.

Inventive Principle:

Principle #40Composite materials

2Temperature

If the portable storage unit adds insulated compartments for temperature-sensitive items, then the temperature control capability is improved, but the device complexity increases

Engineering Contradiction:

Improvetemperature control capabilityVSAvoiddevice complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The storage unit is divided into multiple separate compartments (first compartment, second compartment, third compartment) with distinct functions. The first and second compartments form a nested structure that can be separated, while the third compartment provides additional storage. This segmentation allows each compartment to be optimized for specific purposes (waterproof storage, insulated storage, general storage) while maintaining overall portability.

3Adaptability or versatility

If the portable storage unit uses removable internal components, then the adaptability and versatility are improved, but the device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The storage unit is divided into multiple separate compartments (first compartment, second compartment, third compartment) with distinct functions. The first and second compartments form a nested structure that can be separated, while the third compartment provides additional storage. This segmentation allows each compartment to be optimized for specific purposes (waterproof storage, insulated storage, general storage) while maintaining overall portability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection between the first compartment and second compartment uses a dynamic fastening mechanism (snap fasteners, zippers, or magnetic connections) that allows the compartments to be easily attached and detached. This dynamic design enables the user to reconfigure the storage unit based on needs, transforming it from a static structure to an adaptable system without requiring complex assembly mechanisms.
