Solution Overview

Problem

There is a need for a new and distinct cultivar of Coreopsis verticillata that combines specific characteristics such as bright yellow inflorescences, medium green deeply-dissected foliage, and a compact growth habit, which are not adequately represented in existing commercially available cultivars.

Innovation Solution

The cultivar 'Sylvester' is developed through open pollination, characterized by bright yellow inflorescences, medium green deeply-dissected foliage, moderate growth vigor, and a well-branched upright-mounded growth habit, differing from similar cultivars like 'Zagreb' and 'Tweety' in terms of height, flower size, branching, and foliage color.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a new Coreopsis cultivar is developed to combine specific characteristics (bright yellow inflorescences, medium green deeply-dissected foliage, compact growth habit), then the distinctiveness and commercial value of the cultivar is improved, but the complexity of breeding and selection process increases

Engineering Contradiction:

Improvedistinctiveness of cultivar characteristicsVSAvoidbreeding and selection process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple desirable traits (bright yellow inflorescences, medium green deeply-dissected foliage, compact upright-mounded growth habit, well-branched structure) into a single new cultivar 'Sylvester' through controlled open pollination breeding, merging characteristics from parent plants to create a unified cultivar with all desired features simultaneously

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent uses asexual propagation by terminal stem cuttings to create exact genetic copies of the selected plant, ensuring that the unique combination of characteristics is replicated true to type across multiple generations, preserving the distinctiveness achieved through the breeding process

Inventive Principle:

Principle #26Copying

2Measurement precision

If the new cultivar 'Sylvester' is compared to similar cultivars like 'Zagreb' and 'Tweety' to ensure distinctiveness, then the uniqueness of the cultivar is improved, but the time and resources required for comparison and evaluation increase

Engineering Contradiction:

Improvedistinctiveness evaluation accuracyVSAvoidcomparison and evaluation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary comparison evaluations against known cultivars ('Zagreb' and 'Tweety') during the breeding and selection process to identify and select plants with distinct characteristics before formal cultivar registration, reducing the need for extensive post-breeding comparisons

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces extensive field trials and mechanical measurements with visual and morphological assessment of key characteristics (foliage color, inflorescence color, growth habit, branching pattern) to evaluate distinctiveness, substituting complex measurement systems with expert botanical evaluation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
