Solution Overview

Problem

There is a need for a new peach tree variety that combines unique fruit characteristics such as flat shape, mottled red over color on an orange ground, high productivity, sweet flavor, melting flesh texture, and firmness that retains well, which existing peach varieties do not adequately provide.

Innovation Solution

The 'NJF18' peach tree variety, resulting from crossing 'H15-20-90258' and 'A34-160-782118', exhibits flat fruit shape, pubescent skin, and specific growth habits, reproduced asexually onto 'Lovell' rootstock, maintaining these characteristics across environmental changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If traditional peach varieties are used, then fruit production is maintained, but fruit shape remains round and lacks unique market appeal

Engineering Contradiction:

Improvefruit shapeVSAvoidfruit production

Core Design Contradiction:

ShapeVSProductivity

Solution Approach 1:

The patent combines multiple desirable traits from different parent varieties into a single new variety 'NJF18'. The flat fruit shape was inherited from parent 'H15-20-90258' while pubescent skin and other characteristics came from parent 'A34-160-782118', creating a unique combination that distinguishes this variety in the market while maintaining productivity

Inventive Principle:

Principle #5Merging (Combining)

2Strength

If fruit firmness is increased for shipping, then shipping quality improves, but flesh texture becomes less melting and enjoyable

Engineering Contradiction:

Improvefruit firmnessVSAvoidflesh texture

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent achieves different texture qualities in different parts of the fruit. The skin and outer flesh provide firmness for shipping durability, while the inner flesh maintains a melting, tender texture for eating quality. This local differentiation of properties allows the fruit to satisfy both shipping requirements and consumer preferences

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If fruit color is made more vibrant for market appeal, then consumer attraction increases, but natural color stability under varying environmental conditions becomes challenging

Engineering Contradiction:

Improvemarket appealVSAvoidcolor stability

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The fruit exhibits a complex color composition with mottled red overcolor on an orange ground color, creating a visually appealing multi-toned appearance. This composite color structure provides both market attractiveness and natural variation that helps stabilize the overall color expression under different environmental conditions

Inventive Principle:

Principle #40Composite materials
