Solution Overview

Problem

There is a need for compact, sterile Buddleja plants with unique and attractive flower coloration that can thrive in various environmental conditions and exhibit stable characteristics across generations.

Innovation Solution

A new cultivar, 'Podaras #16', resulting from a cross-pollination between unnamed selections of Buddleja davidii×Buddleja alternifolia, exhibits a compact and spreading habit, sterile light violet flowers, and good garden performance, distinguishing it from its parents and comparable varieties like 'Pink Delight'.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional Buddleja breeding methods are used, then flower coloration can be varied, but plant size becomes large and flowering becomes non-sterile

Engineering Contradiction:
Improveflower coloration varietyVSAvoidplant size
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The patent applies parameter changes by systematically varying breeding parameters including parental selection (crossing Buddleja davidii with Buddleja alternifolia), controlling pollination conditions, and selecting for specific traits in progeny. This resulted in cultivars with modified plant size parameters (compact growth) and flowering characteristics (sterility) while maintaining color variation

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If traditional Buddleja breeding methods are used, then flower coloration can be varied, but plant sterility is not achieved

Engineering Contradiction:
Improveflower coloration varietyVSAvoidplant sterility
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The breeding program changed the genetic parameters through controlled cross-pollination between specific parent selections, selecting progeny that exhibited sterility as a stable trait. The resulting cultivars consistently produce sterile flowers across generations, representing a reliable change in the reproductive parameter

Inventive Principle:
Principle #35Parameter changes

3Volume of moving object

If compact growth is selected for, then plant size is reduced, but growth stability across generations may be compromised

Engineering Contradiction:
Improveplant sizeVSAvoidgrowth habit stability
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action through extensive preliminary breeding work and selection processes. Multiple generations of selection were performed to establish compact growth as a stable, heritable trait before the cultivar was considered ready for propagation. This preliminary selection ensured that compact growth habit would be reliably transmitted to successive generations

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If unique flower coloration is selected for, then flower color distinctiveness is improved, but genetic variability may be reduced

Engineering Contradiction:
Improveflower color uniquenessVSAvoidgenetic variability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by selecting for specific local traits (unique flower coloration) while maintaining overall genetic health through controlled cross-pollination. Each cultivar was selected for its distinctive color characteristics (lavender, pink, white, bicolor patterns) while the breeding program maintained sufficient genetic variability through diverse parental selections

Inventive Principle:
Principle #3Local quality
