Solution Overview

Problem

Current methods for removing ethylene from storage environments are costly and inefficient, particularly as they require breaking down ethylene into carbon dioxide and water, which necessitates expensive equipment and high energy consumption, and there is a need for a method that traps ethylene without using chemicals, especially in organic food storage where preservatives are not permitted.

Innovation Solution

An apparatus and method utilizing an ethylene filter with a trapping medium and a composition containing titanium dioxide, which attaches to ethylene in the gas flow, combined with a UV light source to render contaminants inert and a sodium silicate filter to remove moisture, allowing ethylene to be trapped and removed from the environment without breaking it down.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ethylene is broken down into carbon dioxide and water using conventional methods, then ethylene removal is achieved, but equipment cost and energy consumption increase significantly

Engineering Contradiction:
Improveethylene removal effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts ethylene from the gaseous environment using a filter assembly that traps ethylene molecules on the filter medium, separating them from the air stream without requiring energy-intensive breakdown processes. The filter physically removes ethylene through adsorption onto the filter medium surface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The filter assembly acts as an intermediary component between the gaseous environment and the external system. It captures ethylene through a chemical or physical interaction with the filter medium, providing a low-energy removal mechanism that mediates between the need for ethylene elimination and energy conservation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Duration of action of moving object

If chemical additives are used to prevent ripening, then shelf life is extended, but compliance with organic food standards is violated

Engineering Contradiction:
Improveshelf lifeVSAvoidchemical contamination
Core Design Contradiction:
Duration of action of moving objectVSObject-affected harmful factors

Solution Approach 1:

The system extracts and removes ethylene gas from the storage environment using a physical filter assembly, avoiding the need to add any chemical substances to the food or packaging. This extraction approach extends shelf life while maintaining organic certification compliance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces chemical preservation methods with a mechanical/physical filtration system. The filter assembly uses physical adsorption mechanisms rather than chemical reactions to remove ethylene, substituting a mechanical removal process for chemical preservation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If ethylene filter with trapping medium is used, then ethylene is trapped and removed, but device complexity increases

Engineering Contradiction:
Improveethylene removal effectivenessVSAvoidfilter assembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The filter assembly is designed to perform multiple functions within a single component structure: filtering ethylene from the air stream while allowing breathable gases to pass through. The trapping medium provides both structural support and ethylene capture functionality, reducing the need for separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The filter medium utilizes a porous structure that allows selective passage of gases. The porous material provides large surface area for ethylene adsorption while maintaining air permeability, achieving effective ethylene removal with a simple, lightweight filter design rather than complex mechanical systems.

Inventive Principle:
Principle #31Porous materials

AI summary

An apparatus, system, and method are disclosed for removing ethylene from a gaseous environment. Ethylene is a gaseous growth hormone produced by plants that triggers the ripening of some flowers, fruits, vegetables, and other plants. The apparatus includes an ethylene filter and a composition. The filter includes a frame and a trapping medium. The composition is attached to the trapping medium of the ethylene filter. The ethylene filter is positioned within a gaseous environment and is configured to encounter a gas flow within the gaseous environment. The composition contains at least some titanium dioxide which is configured to attach to the ethylene as the gas flow moves through and around the ethylene filter. In this manner, some ethylene may be removed from the gaseous environment.
