Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a lack of apple tree cultivars that combine unique flavor profiles, texture, color, and resistance to early fruit drop, with a spreading tree habit, making it difficult to find varieties suitable for fresh-eating, dessert, and cooking purposes that are also resistant to specific diseases.

Innovation Solution

The development of the 'Cherry Parfait #19' apple tree cultivar, resulting from crossing PINK LADY and Honeycrisp varieties, which exhibits a citrus flavor profile, crisp texture, pink color, and resistance to early fruit drop, with a spreading habit, and is suitable for fresh-eating, dessert, and cooking, while also showing tolerance to certain diseases and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If apple tree cultivars are developed with unique flavor profiles and texture, then fruit quality is improved, but resistance to early fruit drop and disease susceptibility may worsen

Engineering Contradiction:

Improveresistance to early fruit dropVSAvoiddisease susceptibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The apple tree cultivar combines genetic traits from two parent varieties (PINK LADY and Honeycrisp) to create a composite genetic structure that integrates disease resistance, fruit drop resistance, and superior fruit quality traits that neither parent possessed alone

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If apple tree cultivars are developed with spreading tree habit, then ease of operation is improved, but adaptability to various ecological conditions may worsen

Engineering Contradiction:

Improveease of harvestingVSAvoidadaptability to ecological conditions

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The cultivar exhibits a spreading tree habit that creates localized advantages for ease of harvesting and maintenance operations, while maintaining overall adaptability to various ecological conditions through the robust genetic foundation from its parent varieties

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If apple tree cultivars are developed for fresh-eating and dessert purposes, then product versatility is improved, but productivity may worsen

Engineering Contradiction:

Improveproduct versatilityVSAvoidfruit yield

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The apple tree cultivar is designed with multi-functionality, producing fruit that excels in fresh-eating quality, dessert applications, and cooking uses, while maintaining adequate productivity levels through balanced genetic inheritance from parent varieties known for both quality and yield

Inventive Principle:

Principle #6Universality (Multi-functionality)
