Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a new Veronica cultivar that exhibits improved resistance to powdery mildew, increased vigor, larger and darker green leaves, and a richer pink flower color, while maintaining a long and continuous flowering season from late Spring to late Summer, which existing varieties fail to provide effectively.

Innovation Solution

The Veronica cultivar 'PINK PASSION' is developed, characterized by its strong pink flower color, bushy habit, prolific branching, and enhanced resistance to powdery mildew, which distinguishes it from its parent and comparable varieties, achieved through asexual reproduction by vegetative terminal cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing Veronica varieties are used, then they can be grown and flower, but they show poor resistance to powdery mildew and lack vigor

Engineering Contradiction:

Improveresistance to powdery mildewVSAvoidsusceptibility to powdery mildew

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by selecting and propagating a plant with specific genetic parameters that confer resistance to powdery mildew. The cultivar 'PINK PASSION' exhibits altered biological parameters including disease resistance, vigor, and growth characteristics compared to existing varieties, directly resolving the contradiction between reliability and susceptibility to harmful factors.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If existing Veronica varieties are used, then they can produce flowers, but the flower color is not rich pink and the leaves are not larger and darker green

Engineering Contradiction:

Improveflower color intensityVSAvoidnatural color expression

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent utilizes parameter changes in the genetic makeup of the cultivar to achieve richer pink flower color and larger, darker green leaves. The natural expression of these traits in 'PINK PASSION' demonstrates altered pigmentation and foliage parameters that satisfy the contradiction between color intensity and natural growth characteristics.

Inventive Principle:

Principle #35Parameter changes

3Duration of action of moving object

If existing Veronica varieties are used, then they can flower, but the flowering season is not long and continuous from late Spring to late Summer

Engineering Contradiction:

Improveflowering season durationVSAvoidcontinuous flowering capacity

Core Design Contradiction:

Duration of action of moving objectVSProductivity

Solution Approach 1:

The patent applies parameter changes in the phenological characteristics of the cultivar, specifically in flowering time and duration parameters. The cultivar 'PINK PASSION' exhibits extended flowering season parameters that enable continuous blooming from late Spring to late Summer, resolving the contradiction between duration and productivity of flowering.

Inventive Principle:

Principle #35Parameter changes

4Strength

If existing Veronica varieties are used, then they can grow, but they lack vigor and do not exhibit prolific branching

Engineering Contradiction:

Improveplant vigorVSAvoidbranching structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent utilizes parameter changes in growth and structural parameters of the cultivar. The enhanced vigor and prolific branching characteristics of 'PINK PASSION' represent altered growth rate, biomass accumulation, and structural development parameters that resolve the contradiction between strength and structural complexity.

Inventive Principle:

Principle #35Parameter changes
