Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging additives such as oxygen absorbers, desiccants, and humectants are often loose within packages, risking consumption or damage and start working immediately, losing effectiveness before the final product is sealed.

Innovation Solution

Packaging additives are sealed and attached to the container, protected from atmosphere until activated by peeling, puncturing, or other techniques, allowing delayed functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If packaging additives are added loose inside the package, then they are easy to install and manufacture, but they risk being consumed or damaging equipment and start working immediately losing effectiveness

Engineering Contradiction:

Improveease of installationVSAvoideffectiveness timing

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The packaging additive is segmented into two functional parts: an active element (oxygen absorber, desiccant, etc.) and an inert support structure (pod, sachet, or container). This segmentation allows the active element to be protected within the inert structure during shipping and handling, preventing premature activation and accidental consumption, while still being easy to install as a complete unit.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An inert support structure (pod, sachet, or container) is introduced as an intermediary between the active element and the package environment. This intermediary protects the active element from premature exposure to atmosphere and potential damage, while allowing controlled activation when needed. The inert structure acts as a mediator that enables safe transport and delayed activation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If packaging additives start working immediately upon exposure to atmosphere, then they begin functioning right away, but they lose effectiveness before the final product is sealed

Engineering Contradiction:

Improveactivation speedVSAvoideffectiveness duration

Core Design Contradiction:

ProductivityVSDuration of action of moving object

Solution Approach 1:

The packaging additive is prepared in advance with all necessary components (active element, inert support structure, sealing mechanism) assembled and protected before the final product is sealed. The active element is pre-positioned within the inert structure, ready for immediate activation once the package is sealed, ensuring no loss of effectiveness during the sealing process.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If packaging additives are attached to the container, then they remain secured and protected, but they require additional attachment steps increasing complexity

Engineering Contradiction:

Improvesecurity and protectionVSAvoidattachment process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The active element and inert support structure are merged into a single integrated unit (pod or sachet) that can be easily attached to the container. This merging eliminates the need for separate attachment steps for the active element, as the entire functional unit is designed to be securely attached in one operation, reducing overall complexity while maintaining security and protection.

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Ensures packaging additives remain effective upon first use, preventing premature activation and maintaining product quality.

Implementation Method 1

oxygen absorbers also known as oxygen scavengers are active elements usually added to a packaging container to lower the residual oxygen level

Methodology Applied

Scientific EffectOxygen absorption: Absorption (physical)

Implementation Method 2

Desiccants or dryers are active elements also added in sachet form to various products. The most common desiccant is silica gel

Methodology Applied

Scientific EffectDesorption: Desorption

Implementation Method 3

Another active element is a humectant or hygroscopic (water-absorbing) substance used to reduce the loss of moisture and keep things moist

Methodology Applied

Scientific EffectHygroscopy: Absorption (physical)

AI summary

Improved packaging system wherein a single absorber is sealed and attached to the product (e.g., food) container. The container may be a bag, trays, etc. The absorber would be attached by: a) placing an absorber on film while the film is being converted into a bag, or b) the bag customer could insert pod style absorber by sticking to an inner wall of bag. There could be two main styles of absorber pod: a) one that pod is premade and then either adhesive is used to attach to package or the pod is heat sealed to package, or b) individual pods are manufactured, and the user could install them inside the container in the same manners.
