Solution Overview

Problem

There is a need for a new cultivar of Malcolmia maritima that exhibits upright and mounding growth, long flowering duration, winter hardiness, and attractive uniform flower coloration, which existing cultivars do not adequately provide.

Innovation Solution

A new cultivar, 'Sunmalconpi', was developed through planned breeding in Japan, resulting from a cross-pollination between proprietary selections of Malcolmia maritima, characterized by its upright and mounding habit, vigorous growth, freely branching and flowering, dark pink flowers, and good garden performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing Malcolmia maritima cultivars are used, then they may have certain growth characteristics, but they fail to provide the desired combination of upright and mounding growth, long flowering duration, winter hardiness, and attractive uniform flower coloration

Engineering Contradiction:

Improvegrowth habit and flowering characteristicsVSAvoidflowering duration and winter hardiness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled cross-pollination between selected parental lines to achieve the desired combination of upright and mounding growth habit, extended flowering duration, winter hardiness, and uniform dark pink flower coloration in the 'Sunmalconpi' cultivar

Inventive Principle:

Principle #35Parameter changes

2Volume of moving object

If plant size is reduced for better garden performance, then compactness is improved, but flowering frequency and overall vigor may be compromised

Engineering Contradiction:

Improveplant sizeVSAvoidflowering frequency

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The 'Sunmalconpi' cultivar exhibits different growth characteristics in different parts of the plant - the overall plant maintains a compact volume suitable for garden performance, while the flowering portions demonstrate high productivity with frequent blooms and vigorous flower development, achieving local optimization of both size and flowering frequency

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If cross-pollination breeding is conducted to develop new characteristics, then genetic diversity and new traits are achieved, but breeding time and program complexity increase

Engineering Contradiction:

Improvenew cultivar characteristicsVSAvoidbreeding program duration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The breeding program utilized pre-selected parental lines with known desirable traits, and conducted controlled cross-pollination with planned selection of progeny, thereby accelerating the development of the 'Sunmalconpi' cultivar with the desired combination of characteristics while reducing the overall breeding time

Inventive Principle:

Principle #10Preliminary action
