Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cut flowers have a short life-cycle and often fail to fully open their buds, leading to reduced aesthetic appeal and significant value loss due to perishability.

Innovation Solution

Exposing the stems of cut flowers to an oxytocin solution, such as an aqueous oxytocin solution, at specific concentrations and exposure times, to enhance bud opening and longevity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cut flowers are transported over long distances, then availability increases, but longevity and quality are reduced due to short life-cycle

Engineering Contradiction:

ImproveavailabilityVSAvoidlongevity

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action by treating cut flowers with oxytocin solution before they enter the supply chain. This pre-treatment primes the flowers to delay senescence and maintain bud opening, allowing them to withstand long-distance transport and extended supply chain duration without quality degradation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the chemical parameter of the flower system by introducing oxytocin, a peptide hormone. This parameter change triggers physiological responses that extend vase life and maintain flower quality, resolving the contradiction between extended transport time and reduced longevity.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If cut flowers are harvested before bud opening, then transportability improves, but aesthetic appeal decreases due to incomplete bud opening

Engineering Contradiction:

ImprovetransportabilityVSAvoidbud opening

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The oxytocin treatment is applied as a preliminary action before harvest and transport. This pre-treatment ensures that buds will open fully upon arrival at the destination, combining the transportability benefits of pre-harvest cutting with the aesthetic benefits of complete bud opening.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Oxytocin acts as an intermediary substance that mediates between the conflicting requirements of early harvest (for transportability) and full bud opening (for aesthetics). The hormone triggers physiological changes that allow buds to remain closed during transport but open completely when placed in water at the destination.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Duration of action of stationary object

If oxytocin concentration is increased, then bud opening and longevity improve, but cost and complexity of the solution increase

Engineering Contradiction:

ImprovelongevityVSAvoidsolution complexity

Core Design Contradiction:

Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent optimizes the concentration parameter of oxytocin to achieve the desired effect with minimal complexity. By determining the effective concentration range, the patent balances the benefit of extended longevity against the cost and complexity of preparing and managing the oxytocin solution.

Inventive Principle:

Principle #35Parameter changes
