Solution Overview

Problem

Conventional tea bags are made of plastic and do not contain whole leaf tea, which results in inferior tea flavor and potential health risks due to toxic plastic components. Additionally, they are not biodegradable, causing environmental concerns.

Innovation Solution

The development of biodegradable pillow tea bags made from materials like Polylactic Acid (PLA) fibers, which are used to create a sleeve structure that can hold whole leaf tea. The tea bags are manufactured using a system that involves vertical and horizontal sealing mechanisms to form sealed compartments containing whole leaf tea, and can optionally be infused with CBD oil or other supplements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional tea bags are made of plastic and contain broken leaves, then manufacturing cost and ease of production are improved, but health safety and environmental compatibility deteriorate

Engineering Contradiction:

Improveease of productionVSAvoidhealth safety

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to biodegradable materials (paper, mesh fabric, silk, gauze, bioplastics), and changes the tea leaf parameter from broken leaves to whole leaf tea, thereby eliminating harmful factors while maintaining manufacturability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material structures combining biodegradable wrapping materials with whole leaf tea, and optionally incorporates CBD oil infusion, creating a multi-component system that addresses both health safety and environmental concerns

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If conventional tea bags are made of plastic, then ease of manufacture is improved, but biodegradability and environmental compatibility deteriorate

Engineering Contradiction:

Improveease of productionVSAvoidbiodegradability

Core Design Contradiction:

Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The patent changes the material composition parameter from synthetic plastic to biodegradable materials including paper, mesh fabric, silk, gauze, and bioplastics, enabling the tea bags to decompose naturally and improve environmental compatibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs disposable biodegradable tea bags that are designed for single use and then naturally decompose, replacing persistent plastic products with environmentally friendly alternatives that eliminate long-term environmental pollution

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If tea bags are made small to fit broken leaves, then ease of manufacture is improved, but tea flavor infusion deteriorates

Engineering Contradiction:

Improveease of productionVSAvoidtea flavor infusion

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent inverts the conventional approach by using whole leaf tea instead of broken leaves, and consequently uses larger pillow-shaped tea bags instead of small conventional bags, allowing proper expansion and infusion of the tea leaves for optimal flavor

Inventive Principle:

Principle #13The other way round (Inversion)

4Ease of manufacture

If plastic is used in tea bags, then ease of manufacture is improved, but environmental harm increases

Engineering Contradiction:

Improveease of productionVSAvoidenvironmental harm

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to biodegradable alternatives (paper, mesh fabric, silk, gauze, bioplastics), transforming the product from environmentally harmful to environmentally friendly while maintaining manufacturing feasibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the previously harmful plastic material into beneficial biodegradable materials that provide both manufacturing ease and environmental benefit, turning a harmful characteristic into a useful one through material substitution

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A biodegradable whole leaf pillow tea bag is provided, along with a system and method for manufacturing biodegradable whole leaf pillow tea bags. The method for manufacturing the whole leaf pillow tea bags includes the steps of providing a biodegradable infusion substrate having two opposing edge; creating a sleeve from the biodegradable infusion substrate by infusing the two opposing edges of the substrate together and closing the sleeve at its bottom; placing whole leaf tea in the bottom of the sleeve; vertically feeding the sleeve containing the whole leaf tea into a heat sealing machine that will, at predetermined intervals create heat seals across the sleeve to create pillow bags; cutting the pillow bags from one another across the heat seal. In one example, the biodegradable infusion substrate may contain hemp and/or the whole leaf tea may be infused with CBD oil or other supplements. The same method of manufacturing may be used to create a biodegradable pillow bag containing coffee.
