Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging designs for food products like leafy greens fail to maintain freshness and prevent moisture loss, as they either allow the product to extend out of the container or hinder proper sealing, and lack efficient portioning mechanisms.

Innovation Solution

A packaging apparatus comprising a container base with a first layer of material fixed to it, featuring an opening for filling, and a second resealable layer that completely seals the container, using heat sealing or adhesive, and includes a tamper-evident perforated panel to maintain moisture and extend shelf life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single layer of material is used to seal the container base, then the packaging structure is simple, but the food product can extend out of the container or moisture loss occurs

Engineering Contradiction:

Improvepackaging structureVSAvoidsealing effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The packaging structure is divided into two separate layers: a first layer fixed to the container base and a second layer that seals over the first layer. This segmentation allows each layer to perform its specific function - the first layer provides structural support and anchoring, while the second layer provides the sealing function, preventing food extension and moisture loss.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first layer is nested within the container base structure, with its periphery extending beyond the food product. The second layer is then placed over the first layer, creating a nested configuration where the second layer seals over the exposed periphery of the first layer, ensuring complete containment.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the first layer of material is fixed to the container base before filling, then the food product is fully contained, but the packaging requires additional manufacturing steps

Engineering Contradiction:

Improveproduct containmentVSAvoidmanufacturing process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The first layer of material is fixed to the container base before the food product is inserted. This preliminary action ensures that the layer is properly positioned and secured, preventing any food product from extending out during filling. The opening in the first layer guides the food product into the container base while the fixed periphery contains it.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the opening in the first layer is spaced from the outer periphery, then the food product is contained, but the sealing area is reduced

Engineering Contradiction:

Improvefood containmentVSAvoidsealing area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The first layer of material has different functional zones: a central opening area that allows food insertion and a peripheral sealing area that extends beyond the food product. This local differentiation ensures that the opening is sufficiently spaced from the periphery to contain food, while the peripheral area provides adequate surface area for effective sealing by the second layer.

Inventive Principle:

Principle #3Local quality
