Solution Overview

Problem

Existing containers lack convenience and versatility, often wasting resources as they cannot efficiently accommodate multiple items or facilitate easy separation and resealing, particularly in e-commerce returns where multiple products are packaged together.

Innovation Solution

The development of separable multi-compartment containers that can be coupled and separated without tools, featuring a lid flap for securing and sealing compartments, with perforation lines and tear strips for easy separation, allowing for flexible use in packaging and display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single compartment container is used, then the structure is simple, but it cannot efficiently accommodate multiple items and wastes space

Engineering Contradiction:
Improveaccommodation of multiple itemsVSAvoidcontainer structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is divided into multiple separable compartments that can be configured in different arrangements. The compartments are connected by perforation lines allowing them to be separated or reconfigured, enabling efficient accommodation of multiple items with varying sizes and shapes while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple compartments are permanently attached, then space utilization is improved, but the container lacks versatility for different shipping scenarios including returns

Engineering Contradiction:
Improveflexibility for different shipping scenariosVSAvoidseparation and reconfiguration
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The container transitions from a static permanently-attached design to a dynamic separable structure. The perforation lines enable compartments to be easily separated or reconfigured based on shipping needs, allowing the same container to serve multiple purposes including forward shipping and returns, thereby improving versatility without significantly compromising ease of operation.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If compartments are separated without tool assistance, then ease of operation is improved, but structural integrity may be compromised

Engineering Contradiction:
Improvetool-free separationVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The container incorporates perforation lines that strategically segment the structure at predetermined locations. These perforation lines are designed to be easily torn by hand while maintaining structural integrity during normal shipping conditions. The perforation lines allow tool-free separation when needed, yet the overall container structure remains strong and intact during standard handling and shipping operations.

Inventive Principle:
Principle #1Segmentation

AI summary

A container can comprise a first compartment, a second compartment, and a lid flap. The container can be moved between a closed configuration and an open configuration. In the closed configuration, the first compartment and the second compartment are closed and the lid flap extends from the first compartment to the second compartment and restricts relative movement between the first compartment and the second compartment. In the open configuration, the first compartment can be separated from the second compartment and resealed with the lid flap.
