Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing garden mum cultivars lack a double type inflorescence with a natural season flowering date around week 39 and a prolonged blooming period of 5 weeks, with limited options for growers seeking specific inflorescence color and duration.

Innovation Solution

The development of the Chrysanthemum×morifolium Ramat. cultivar 'Zanmumajes' with purple inflorescences and a dark center, resulting from a breeding program aimed at creating a double type inflorescence, which blooms for 5 weeks and has a natural flowering date around week 39, differing from its parents in inflorescence color and size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing garden mum cultivars are used, then growers have limited options for specific inflorescence color and duration, but the lack of double type inflorescence with natural season flowering date around week 39 and prolonged blooming period of 5 weeks remains

Engineering Contradiction:

Improveinflorescence color and blooming duration optionsVSAvoidblooming period

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crosses between parent plants with different characteristics (id 28184 and id 26513), selecting for specific trait combinations that produced the desired double type inflorescence, purple coloration, week 39 flowering date, and extended 5-week blooming period in cultivar 'Zanmumajes'

Inventive Principle:

Principle #35Parameter changes

2Duration of action of stationary object

If the cultivar 'Zanmumajes' is developed with specific flowering date week 39, then the blooming period is extended to 5 weeks, but the inflorescence size is reduced to small-sized blooms

Engineering Contradiction:

Improveflowering periodVSAvoidinflorescence size

Core Design Contradiction:

Duration of action of stationary objectVSVolume of moving object

Solution Approach 1:

The cultivar exhibits local quality differentiation within the inflorescence structure, with purple ray florets forming the outer decorative layer and a concentrated dark center composed of densely packed florets, creating visual depth and complexity that compensates for the smaller overall size

Inventive Principle:

Principle #3Local quality

3Duration of action of moving object

If the cultivar produces small-sized blooms, then the blooming period is prolonged to 5 weeks, but the inflorescence diameter is reduced to 3 cm

Engineering Contradiction:

Improveblooming durationVSAvoidinflorescence diameter

Core Design Contradiction:

Duration of action of moving objectVSLength of stationary object

Solution Approach 1:

The cultivar employs sophisticated color variation with purple ray florets (N77B) transitioning to a dark center (187B), creating a gradient effect that enhances the visual impact of the compact 3 cm inflorescence and maintains aesthetic appeal throughout the extended 5-week blooming period

Inventive Principle:

Principle #32Color changes
