Solution Overview

Problem

Existing Campanula cultivars face challenges in maintaining extended bloom times and desirable flower colors, as well as susceptibility to pests and diseases, particularly snails, slugs, and aphids, with limited resistance.

Innovation Solution

The development of Campanula 'Pink Octopus', a unique cultivar resulting from crossing Campanula takesimana 'Beautiful Trust' and Campanula punctata 'Pink Chimes', characterized by large, purple-pink, octopus-like flowers and deep green, glossy leaves, achieved through asexual propagation by tissue culture, ensuring consistent characteristics and low seed set for prolonged blooming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If Campanula cultivars are bred for extended bloom time through low seed set, then the flowering duration is improved, but the fertility and seed production deteriorate

Engineering Contradiction:

Improvebloom timeVSAvoidseed set

Core Design Contradiction:

Duration of action of stationary objectVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by selectively breeding plants with modified fertility parameters. The 'Pink Octopus' cultivar exhibits very low seed set as a deliberate parameter change that extends the bloom period from typical seasonal durations to extended flowering periods, directly resolving the contradiction between bloom time and seed production

Inventive Principle:

Principle #35Parameter changes

2Shape

If Campanula cultivars are developed with vibrant flower colors and unique floral forms, then the aesthetic quality is improved, but the susceptibility to pests and diseases worsens

Engineering Contradiction:

Improveflower form and colorVSAvoidpest and disease susceptibility

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by developing region-specific cultivars adapted to particular environmental conditions. The 'Pink Octopus' cultivar shows resistance to snails, slugs, and aphids in the Pacific Northwest climate, demonstrating that localized breeding strategies can provide pest resistance while maintaining distinctive floral characteristics of vibrant purple-pink colors and octopus-like lobed forms

Inventive Principle:

Principle #3Local quality

3Stability of the object's composition

If Campanula cultivars are propagated asexually through tissue culture to maintain consistent characteristics, then the genetic uniformity is improved, but the adaptability to environmental variations worsens

Engineering Contradiction:

Improvegenetic uniformityVSAvoidenvironmental adaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies preliminary action by performing extensive preliminary breeding and selection work to develop cultivars with built-in environmental adaptability. The 'Pink Octopus' cultivar was developed through multi-year breeding programs that pre-adapted the plant to Pacific Northwest conditions, allowing tissue culture propagation to maintain genetic uniformity while the cultivar itself remains environmentally resilient
