Solution Overview

Problem

There is a need for a new apple tree variety that combines precocious tree habit with excellent fruit characteristics, such as firmness, juiciness, and tartness, which are retained after cold storage, and differs from existing varieties like 'Braeburn' and 'Autumn Crisp' in terms of fruit size, color, shape, and maturity.

Innovation Solution

The development of the 'New York 2' apple tree variety, derived from crossing 'Braeburn' and 'Autumn Crisp', which exhibits a unique combination of traits including large fruit size, deeper red color, and uniform red pattern, firmness, juiciness, and tartness, and is asexually propagated to ensure consistency across generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If apple variety 'Braeburn' is used, then later maturity and orange-red fruit color are achieved, but fruit size is smaller and color uniformity is reduced

Engineering Contradiction:

Improvematurity timingVSAvoidfruit size

Core Design Contradiction:

ForceVSVolume of moving object

Solution Approach 1:

The patent combines the precocious tree habit and early bearing characteristics from one parent with the firm, crisp, juicy fruit quality and tart flavor from another parent to create a new variety that merges the beneficial traits of both parents while achieving larger fruit size and improved color uniformity

Inventive Principle:

Principle #5Merging (Combining)

2Speed

If apple variety 'Autumn Crisp' is used, then earlier maturity and red blush color on yellow/green background are achieved, but fruit shape becomes globose and color uniformity is reduced

Engineering Contradiction:

Improvematurity speedVSAvoidfruit shape

Core Design Contradiction:

SpeedVSShape

Solution Approach 1:

The new variety exhibits a brighter and deeper red color pattern that is more uniform across the fruit surface, improving upon the blotchy red blush of Autumn Crisp while maintaining early-mid season maturity timing

Inventive Principle:

Principle #3Local quality

3Productivity

If crossing 'Braeburn' with 'Autumn Crisp' is performed, then precocious tree habit and excellent fruit characteristics are achieved, but fruit maturity timing becomes intermediate

Engineering Contradiction:

Improveprecocious tree habitVSAvoidmaturity timing

Core Design Contradiction:

ProductivityVSForce

Solution Approach 1:

The variety exhibits early bearing on spurs and annual productivity, establishing productive behavior early in the tree's development while achieving mid-season fruit maturity that balances the parental extremes

Inventive Principle:

Principle #10Preliminary action
