Solution Overview

Problem

Current Petunia cultivars lack compact, freely branching, and double purple violet-colored flower traits, which are desirable for attractive and stable garden performance.

Innovation Solution

The development of the Petunia×hybrida cultivar 'Kerprilcomp' through controlled cross-pollination, exhibiting a compact and trailing growth habit, freely branching with double purple violet flowers and darker purple venation, achieved via asexual reproduction by terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional Petunia cultivars are used, then they have simpler growth habits and single flowers, but they lack compact trailing growth and double flower structure

Engineering Contradiction:

Improvegrowth habitVSAvoidflower structure

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The patent combines multiple desirable traits from different parent plants through controlled cross-pollination: the compact trailing growth habit from one parent and the double flower structure from another, creating a unified cultivar that exhibits both characteristics simultaneously

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The breeding program selectively modifies key parameters including growth habit (from upright to trailing), flower complexity (from single to double), and flower color intensity, producing a cultivar with optimized characteristics that differ from conventional varieties

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new traits are introduced through cross-pollination, then flower characteristics improve, but stability of reproduction may be compromised

Engineering Contradiction:

Improvegarden performanceVSAvoidgenetic stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent performs preliminary selective breeding and evaluation across multiple generations to establish genetic stability before finalizing the cultivar, ensuring that desirable traits are firmly established and will reproduce consistently

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The breeding program incorporates continuous observation and selection feedback, evaluating progeny for stability of the new traits over successive generations and selecting only those individuals that consistently express the desired characteristics

Inventive Principle:

Principle #23Feedback

3Reliability

If compact trailing growth habit is selected, then garden performance improves, but plant height is reduced

Engineering Contradiction:

Improvegarden performanceVSAvoidplant height

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The patent applies local quality by concentrating growth vigor in lateral spreading and trailing rather than vertical growth, creating a plant that is short in height but extensive in horizontal coverage, optimizing it for ground cover and hanging basket applications

Inventive Principle:

Principle #3Local quality
