Solution Overview

Problem

There is a need for a strawberry variety that excels in producing large, high-yielding fruit with excellent flavor, adapted to the specific climate and growing conditions of the central coast of California, while maintaining fruit quality and being moderately susceptible to powdery mildew.

Innovation Solution

The development of the strawberry variety 'PS-10.1160', which is a result of a controlled cross between 'PS-3.130' and 'PS-4.152', characterized by orange-red fruit color, very large fruit size, high marketable fruit yield, medium plant size, and early flowering and fruiting, specifically adapted to the central coast of California's climate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a strawberry variety is bred for very large fruit size and high marketable yield, then fruit productivity and size are improved, but the plant may become more susceptible to diseases or require more resources

Engineering Contradiction:

Improvemarketable fruit yieldVSAvoiddisease susceptibility

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The breeding program systematically varied genetic parameters through controlled crosses between selected parents, achieving optimal balance between yield parameters and disease resistance parameters in the resulting variety

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The variety combines genetic traits from multiple parent lines, creating a composite genetic structure that integrates high-yield characteristics with moderate disease susceptibility tolerance

Inventive Principle:

Principle #40Composite materials

2Volume of moving object

If a strawberry variety produces very large fruit, then individual fruit size is improved, but the total number of fruits per plant may decrease

Engineering Contradiction:

Improvefruit sizeVSAvoidtotal fruit yield

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The variety achieves optimal parameter balance with season average fruit weight of 30.4g (very large) while maintaining high marketable yield of 2167g per plant through controlled genetic inheritance from parent selections

Inventive Principle:

Principle #35Parameter changes

3Reliability

If a strawberry variety is adapted to specific climate conditions, then fruit quality and consistency are improved, but adaptability to other regions may be reduced

Engineering Contradiction:

Improvefruit quality consistencyVSAvoidclimate adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The variety exhibits local adaptation to central coast California climate conditions, with the Pacific Ocean's humidity and moderate temperatures optimizing fruit quality characteristics including flavor, color, and firmness

Inventive Principle:

Principle #3Local quality

4Loss of time

If a strawberry variety flowers and fruits very early, then time to market is reduced, but the plant may have less time to develop robust foliage and root systems

Engineering Contradiction:

Improvetime to first fruitVSAvoidplant vigor

Core Design Contradiction:

Loss of timeVSStrength

Solution Approach 1:

The variety achieves very early flowering and fruiting by inheriting pre-programmed developmental timing from parent selections, initiating reproductive growth before competing varieties establish full vegetative systems

Inventive Principle:

Principle #10Preliminary action
