Solution Overview

Problem

There is a need for a new sweet cherry tree variety that combines desirable traits such as larger fruit size, late flowering time, and resistance to fruit cracking, while maintaining good fruit quality and being suitable for specific growing conditions like the Czech Republic climate.

Innovation Solution

The development of a new sweet cherry tree variety 'HL 13822' through planned breeding between 'Kordia' and 'Merton Reward', which exhibits distinct characteristics including fruit size, flowering time, and cracking resistance, and has been asexually reproduced via grafting, retaining its traits through successive propagations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If cherry tree variety 'Kordia' is used as parent, then fruit skin and flesh color and firmness are maintained, but harvest time and fruit quality are limited

Engineering Contradiction:

Improvefruit firmnessVSAvoidharvest time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The patent combines the fruit firmness trait from 'Kordia' with the harvest time and fruit quality traits from 'Merton Reward' through planned breeding, creating a new variety that exhibits both parental advantages

Inventive Principle:

Principle #5Merging (Combining)

2Shape

If cherry tree variety 'Merton Reward' is used as parent, then fruit shape is maintained, but harvest time and fruit quality and pedicel length are limited

Engineering Contradiction:

Improvefruit shapeVSAvoidharvest time

Core Design Contradiction:

ShapeVSLoss of time

Solution Approach 1:

The patent merges the fruit shape characteristic from 'Merton Reward' with improved harvest time and fruit quality traits from the breeding program, achieving a balance between form and function

Inventive Principle:

Principle #5Merging (Combining)

3Volume of moving object

If larger fruit size is achieved, then fruit quality is improved, but susceptibility to fruit cracking increases

Engineering Contradiction:

Improvefruit sizeVSAvoidfruit cracking

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the genetic parameters of the cherry tree through breeding to achieve larger fruit size while simultaneously adjusting the skin thickness and structural integrity parameters to resist cracking

Inventive Principle:

Principle #35Parameter changes

4Adaptability or versatility

If late flowering time is achieved, then adaptability to climate is improved, but pollination window is reduced

Engineering Contradiction:

Improveclimate adaptabilityVSAvoidflowering duration

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The patent adjusts the flowering time parameter through breeding to achieve late flowering that adapts to the Czech Republic climate, while maintaining sufficient pollination duration through selection of optimal parental combinations

Inventive Principle:

Principle #35Parameter changes
