Solution Overview

Problem

Current methods for releasing 1-methylcyclopropene (1-MCP) from cyclodextrin or other solid matrices face challenges such as instability, safety concerns due to reactivity, foaming issues, and temperature effects, leading to incomplete release and impurity formation, which complicates regulatory compliance and practical application in plant storage.

Innovation Solution

A system and method utilizing a 1-MCP generator that applies physical forces like rotation, stirring, or steam to dissociate 1-MCP from its carrier complex in water, minimizing foaming and impurity generation, and optimizing release efficiency across varying temperatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If water is used to displace 1-MCP from α-cyclodextrin, then 1-MCP release is achieved, but α-cyclodextrin powder clumps and water column pressure hinders complete release

Engineering Contradiction:
Improve1-MCP release efficiencyVSAvoiddispersibility of α-cyclodextrin powder
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies preliminary action by pre-heating water before introducing it to the α-cyclodextrin/1-MCP powder. This pre-heating prevents powder clumping by ensuring the water is warm enough to facilitate immediate and complete dispersal, while also creating sufficient vapor pressure to overcome the water column pressure and achieve complete 1-MCP release.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If air pump is used to create movement in water, then contact between water and α-cyclodextrin/1-MCP powder is facilitated, but foam forms causing overflow and safety risks

Engineering Contradiction:
Improve1-MCP release completenessVSAvoidfoam formation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical air pump system with a thermal system. Instead of using mechanical agitation and air introduction to facilitate contact, the invention uses heated water whose thermal energy creates vapor pressure and convection currents that naturally promote complete contact between water and powder without generating foam.

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

3Productivity

If chemical additives are used to improve mixing and dispersing, then 1-MCP release is facilitated, but undesirable impurities are generated

Engineering Contradiction:
Improve1-MCP release rateVSAvoidimpurity level control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent extracts and eliminates chemical additives from the system. By using only heated water, the invention removes the source of chemical impurities while maintaining effective 1-MCP release through thermal energy-driven mechanisms such as vapor pressure and convection.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If 1-MCP is stored as gas, then ease of handling is improved, but stability and safety concerns arise due to reactivity and flammability

Engineering Contradiction:
Improvehandling convenienceVSAvoidstorage stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies the nested doll principle by encapsulating 1-MCP gas molecules within the hollow cavity structure of α-cyclodextrin molecules. This nesting stabilizes the volatile and flammable 1-MCP gas, allowing safe storage and handling in solid form, while enabling controlled release when heated water is applied.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

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