Solution Overview

Problem

Existing strawberry varieties face challenges in producing fruit that is both attractive and durable for fresh market sales, with issues such as uneven ripening, high vigor leading to difficult handling, and a darker color that may be perceived as overripe.

Innovation Solution

The development of the 'Sangria' strawberry variety, resulting from a controlled cross between '3F64' and 'Sweet Ann', which exhibits medium vigor, produces large, conical to wedge-shaped fruit with a light red color, improved ripening pattern, and increased firmness, making it more suitable for fresh market sales.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If high vigor plant growth is used, then plant productivity and fruit volume are improved, but handling difficulty and pest control complexity increase

Engineering Contradiction:

Improvefruit volumeVSAvoidhandling ease

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent applies parameter changes by selecting and breeding for intermediate vigor levels rather than maximum vigor. The 'Sangria' variety exhibits medium vigor that balances fruit production volume with manageable plant size and architecture, making the plants easier to handle while maintaining good productivity

Inventive Principle:

Principle #35Parameter changes

2Illumination intensity

If dark red color is produced in fruit, then fruit attractiveness is improved, but perceived overripeness increases

Engineering Contradiction:

Improvefruit color intensityVSAvoidperceived overripeness

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent directly applies color changes by breeding for a lighter red fruit color in the 'Sangria' variety. This lighter red coloration maintains visual attractiveness while avoiding the dark red appearance that signals overripeness to consumers, thus resolving the contradiction between color intensity and perceived ripeness

Inventive Principle:

Principle #32Color changes

3Strength

If firm fruit texture is achieved, then transit quality is improved, but fruit sweetness may be reduced

Engineering Contradiction:

Improvefruit firmnessVSAvoidflavor quality

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent applies parameter changes by optimizing the firmness parameter to a medium level rather than maximum firmness. The 'Sangria' variety exhibits medium firmness that provides adequate transit quality while maintaining good flavor, balancing the trade-off between structural strength and sensory quality

Inventive Principle:

Principle #35Parameter changes

AI summary

A new and distinct variety of strawberry plant (Fragaria x ananassa) named ‘Sangria’ is presented here. This new short-day strawberry variety is characterized by a medium vigor plant which produces large, attractive, semi-glossy, long conical to occasionally wedge-shaped berries with a sweet strawberry flavor and a desirable lighter red color in the interior and exterior. ‘Sangria’ is firmer than its parents, allowing for better transport. While still rare, this variety does tend to have a higher than usual propensity to have leaves with four leaflets as compared with other varieties. The variety, while short-day, is partially remontant in cool coastal environments of California.
