Solution Overview

Problem

There is a need for new strawberry plant varieties that are stable, high-yielding, and agronomically sound to meet the demands of commercial production, with existing varieties varying in quality and susceptibility to disease.

Innovation Solution

The strawberry plant variety 'DrisStrawEighty' is developed through a cross between proprietary parents '50T403' and '169U 96', exhibiting distinct characteristics such as inflorescence at the same level as foliage, medium anthocyanin coloration, straight terminal leaflet shape, and free petal arrangement, and is asexually propagated to ensure stability and true reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If new strawberry plant varieties are developed to improve fruit quality and yield, then productivity and fruit characteristics are enhanced, but stability and true-to-type reproduction may be compromised

Engineering Contradiction:

ImproveyieldVSAvoidstability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The variety undergoes preliminary testing and selection over multiple years (2014-2019) and successive propagations before commercial release. This preliminary action ensures that the variety is stabilized and proven to reproduce true-to-type before widespread cultivation, resolving the contradiction between improving productivity and maintaining stability.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If strawberry varieties are selected for high yield and fruit quality, then productivity improves, but susceptibility to disease and pests may increase

Engineering Contradiction:

ImproveyieldVSAvoidsusceptibility to disease

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The variety exhibits modified parameters including moderate resistance to certain pests and diseases while maintaining high productivity. The selection process identified plants with optimized genetic parameters that balance yield potential with disease resistance, resolving the contradiction between productivity and susceptibility to harmful factors.

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If extensive breeding and selection processes are conducted to achieve desired fruit characteristics, then fruit quality is improved, but the time and complexity of development increases

Engineering Contradiction:

Improvefruit qualityVSAvoidcomplexity of breeding process

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The breeding program utilized self-service mechanisms including natural selection, self-pollination, and asexual propagation through stolons to maintain genetic consistency. This reduced the need for complex人工 intervention while achieving desired fruit qualities, resolving the contradiction between manufacturing precision and device complexity.

Inventive Principle:

Principle #25Self-service
