Solution Overview

Problem

There is a need for new, stable, high-yielding, and agronomically sound raspberry plant varieties that are suitable for machine harvestability, yield, flavor, and fruit integrity during IQF processing, as existing varieties may lack these characteristics.

Innovation Solution

The new raspberry plant variety 'DrisRaspTwentyThree' was developed through a controlled cross between proprietary parents 'W678.2' and 'Meeker', selected for its machine harvestability, yield, flavor, and fruit integrity, and has been asexually propagated and tested for stability and true-to-type reproduction via root cuttings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional raspberry varieties are used, then they can be grown commercially, but they lack machine harvestability and have poor fruit integrity during IQF processing

Engineering Contradiction:

Improvemachine harvestabilityVSAvoidfruit integrity during processing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and breeding raspberry plants with specific phenotypic parameters that enable machine harvestability while maintaining fruit integrity. The variety 'DrisRaspTwentyThree' exhibits modified parameters including cane strength, fruit attachment characteristics, and fruit firmness that allow mechanical harvesting without compromising fruit quality for IQF processing.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If raspberry varieties are selected for high yield, then production increases, but stability and true-to-type reproduction may be compromised

Engineering Contradiction:

ImproveyieldVSAvoidstability and true-to-type reproduction

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action through extensive pre-breeding and selection processes conducted over multiple years (2010-2020) before commercial deployment. The variety underwent preliminary stability testing and true-to-type verification through successive asexual propagations via root cuttings, ensuring that high-yielding characteristics are stably inherited before wide dissemination.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If raspberry plants are bred for thornless canes and upright growth, then ease of harvesting improves, but resistance to pests and diseases may be reduced

Engineering Contradiction:

Improveease of harvestingVSAvoidresistance to pests and diseases

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by developing a raspberry variety with differentiated characteristics: thornless canes and upright growth habit in the vegetative portions for ease of harvesting, while maintaining disease and pest resistance traits in the overall plant constitution. The variety 'DrisRaspTwentyThree' exhibits local modifications in cane morphology without compromising systemic resistance to abiotic stresses and diseases.

Inventive Principle:

Principle #3Local quality
