Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a new and distinct variety of apple tree that can be propagated clonally and exhibits unique fruit attributes, such as size, shape, color, and maturation timing, which are not met by existing varieties like 'Fuji' and 'Sansa'.

Innovation Solution

The 'Picnic' apple tree, resulting from a cross between 'Fuji' and 'Sansa', is propagated using traditional grafting techniques and exhibits stable traits of small, conical, red fruit with low brightness, maturing in late September, differing from its parents and other comparators in significant ways.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional apple varieties like 'Fuji' and 'Sansa' are used, then fruit production is established, but fruit attributes (size, shape, color, maturation timing) do not meet the need for unique characteristics

Engineering Contradiction:

Improvefruit attributes uniquenessVSAvoidtrait stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines traits from two parent varieties ('Fuji' and 'Sansa') through controlled cross-breeding to create a new variety 'Picnic' with unique fruit attributes including small conical shape, red color, and late September maturation, while maintaining clonal propagation stability

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If clonal propagation is used to maintain genetic stability, then trait consistency is achieved, but genetic diversity and adaptability may be limited

Engineering Contradiction:

Improvegenetic stabilityVSAvoidregional adaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent performs preliminary regional adaptability testing across multiple locations before finalizing the variety selection, ensuring the clonally propagated 'Picnic' variety demonstrates consistent performance and adaptability to different environmental conditions while maintaining genetic stability

Inventive Principle:

Principle #10Preliminary action
