Solution Overview

Problem

There is a need for a greater variety of Aechmea cultivars with attractive ornamental features and additional hybrid cultivars that can be easily propagated by seed, as existing Aechmea cultivars lack diversity and efficient seed propagation methods.

Innovation Solution

Development of a new, distinct, and stable Aechmea fasciata cultivar 'Prontoo' through a controlled breeding program, utilizing the Aechmea fasciata inbred lines 130940878 and 130940758, which produces seeds and plants with unique, stable characteristics such as greyed white inflorescence and long-lasting bract production, enabling sexual reproduction and asexual propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional Aechmea cultivars are used, then they have basic ornamental features, but they lack variety and diversity in ornamental characteristics

Engineering Contradiction:

Improvevariety of ornamental featuresVSAvoiddiversity of cultivars

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The breeding program segmented the Aechmea population into distinct inbred lines with specific ornamental traits, then recombined them through controlled crosses to create diverse hybrid cultivars with unique combinations of characteristics

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention changed key ornamental parameters including bract color (greyed white), inflorescence color (greyed white), and flower color (violet-blue to red-purple) through selective breeding, creating cultivars with novel aesthetic properties

Inventive Principle:

Principle #35Parameter changes

2Productivity

If asexual propagation through tissue culture is used, then propagation is achieved, but it is complex and requires specialized facilities

Engineering Contradiction:

Improvepropagation efficiencyVSAvoidpropagation method complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The invention replaced complex mechanical tissue culture systems with simple sexual reproduction through seed propagation, eliminating the need for specialized laboratory equipment while maintaining propagation effectiveness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The hybrid cultivars are designed to be self-propagating through seed production, allowing growers to easily reproduce plants without requiring external tissue culture facilities or specialized technical knowledge

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If hybrid cultivars are developed, then ornamental diversity is improved, but uniformity of morphological characteristics may be reduced

Engineering Contradiction:

Improveornamental diversityVSAvoiduniformity of characteristics

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The invention performed preliminary development of homozygous inbred lines before hybridization, ensuring that parental lines were genetically stable and uniform, which then produced hybrid offspring with consistent and predictable ornamental characteristics

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The breeding program focused on stabilizing specific local ornamental qualities (bract color, inflorescence color, flower color) in the hybrid cultivars, ensuring uniformity in these key aesthetic traits while maintaining overall diversity

Inventive Principle:

Principle #3Local quality
