Solution Overview

Problem

Existing containers lack flexibility in accommodating various shapes and sizes of articles, particularly for portioned food products, and do not provide efficient separation and portioning capabilities.

Innovation Solution

A tray system comprising separable tray portions with foldable end flaps forming flanges, allowing for individual compartments that can be separated and closed with a lid, constructed from materials like paperboard or cardboard, facilitating portioning and maintaining product freshness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional container designs are used, then manufacturing is simple, but flexibility for accommodating various shapes and sizes of articles is poor

Engineering Contradiction:
Improveflexibility for accommodating various shapes and sizesVSAvoidcontainer structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is divided into multiple separable compartments or sections that can be configured in different arrangements. Each compartment can be independently adjusted or removed, allowing the container to adapt to various shapes and sizes of articles while maintaining a relatively simple overall structure based on modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container incorporates movable and adjustable elements such as flexible partitions, reconfigurable walls, or adjustable lids that can be positioned in multiple configurations. This dynamic structure allows the same container to accommodate different article types without requiring completely different container designs.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If non-separable container designs are used, then structural integrity is maintained, but portioning and serving flexibility is limited

Engineering Contradiction:
Improveportioning and serving flexibilityVSAvoidstructural integrity
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The container is designed with separable compartments that can be divided into individual portions. Each compartment maintains its own structural integrity through reinforced edges and interlocking features, while the overall container can be separated into multiple serving portions for convenient distribution and storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Smaller compartments or portions are designed to nest within larger container structures when not in use. This allows the separable portions to be stored compactly within the main container body, maintaining structural organization and integrity while enabling flexible portioning when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If reusable components are implemented, then sustainability is improved, but cleaning and maintenance complexity increases

Engineering Contradiction:
Improvereusability for sustainabilityVSAvoidcleaning and maintenance complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reusable components such as lids, compartments, and seals are designed as removable and extractable elements from the main container body. This allows each component to be easily separated for individual cleaning and maintenance, reducing the complexity of cleaning the entire assembly while promoting reusability and sustainability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The container incorporates flexible, thin-walled materials that are easy to clean and maintain. These flexible components can be quickly rinsed, folded for drying, and reassembled, reducing maintenance complexity while enabling repeated use. The thin-film design also allows for efficient washing and sterilization processes.

Inventive Principle:
Principle #30Flexible shells and thin films
