Solution Overview

Problem

There is a need for new hybrid pepper varieties that offer unique characteristics such as distinct coloration and resistance to diseases, which are not met by existing pepper cultivars.

Innovation Solution

The development of the pepper plant variety 'E20B3752', characterized by its dark yellow and red striped color and square shape, which is asexually propagated and distinguished from parental varieties by its vertical red and yellow stripes, and exhibits resistance to certain tobamovirus pathotypes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing pepper cultivars are used, then production is maintained with known varieties, but unique coloration and disease resistance are not achieved

Engineering Contradiction:

Improvedisease resistanceVSAvoidunique characteristics

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The pepper plant is propagated asexually through segmentation of the plant body (cuttings), allowing preservation of unique genetic traits including disease resistance and distinctive coloration without the need for sexual reproduction and recombination

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new cultivar with changed parameters including dark yellow and red striped coloration, square shape, and resistance to tobamovirus pathotypes, distinguishing it from existing cultivars through modified phenotypic characteristics

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new hybrid pepper varieties are developed, then unique characteristics and disease resistance are achieved, but development time and complexity increase

Engineering Contradiction:

Improvedisease resistanceVSAvoiddevelopment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The unique pepper variety was discovered and selected in advance during commercial crop conduct, with the mutant identified and propagated vegetatively before widespread commercial adoption, avoiding the need for complex multi-generational breeding programs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The pepper plant is reproduced asexually through vegetative propagation (cuttings), creating exact genetic copies of the parent plant with its unique disease resistance and coloration traits, eliminating the complexity of hybridization and genetic recombination

Inventive Principle:

Principle #26Copying

3Stability of the object's composition

If asexual propagation is used, then unique characteristics are preserved, but genetic diversity is reduced

Engineering Contradiction:

Improvetrait consistencyVSAvoidgenetic diversity

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation
