Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pear tree varieties lack a combination of large fruit size, long shelf life, buttery texture, and early flowering characteristics, which are desirable for commercial cultivation and consumer preferences.

Innovation Solution

The development of the 'PREMP33' pear tree variety, resulting from a controlled cross between 'Patrick Barry' and 'Conference' pear trees, which exhibits these traits and has been stabilized through asexual propagation, maintaining its characteristics across generations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing pear tree varieties are cultivated, then they can be grown commercially, but they lack the combination of large fruit size, long shelf life, buttery texture, and early flowering characteristics

Engineering Contradiction:

Improvecombination of desirable traitsVSAvoidconsistency of traits

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple desirable traits (large fruit size, long shelf life, buttery texture, early flowering) into a single pear tree variety through controlled cross-breeding of 'Patrick Barry' and 'Conference' varieties, creating a unified cultivar that exhibits all four characteristics simultaneously

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent uses asexual propagation by budding to create identical copies of the selected 'PREMP33' plant, ensuring that the combination of desirable traits is replicated consistently across multiple generations and commercial plantings

Inventive Principle:

Principle #26Copying

2Stability of the object's composition

If asexual propagation by budding is used to stabilize the variety, then the traits remain true to type across generations, but the process requires multiple generations of observation and selection

Engineering Contradiction:

Improvetrait consistency across generationsVSAvoidtime for stabilization

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent performs preliminary selection of the optimal plant from the initial cross-breeding population based on desirable traits, then immediately propagates this selected plant asexually to lock in the desired characteristics, preventing further genetic variation and reducing the time needed for stabilization

Inventive Principle:

Principle #10Preliminary action
