Solution Overview

Problem

There is a need for new and distinct grapevine varieties that exhibit unique berry characteristics such as color, shape, ripening date, and size, which are not adequately addressed by existing cultivars, and these variations can be influenced by growing conditions, irrigation, fertilization, pruning, and climatic factors.

Innovation Solution

The development of a new grapevine variety named 'SUGRA64', characterized by large, dark red, obtuse ovoid berries with early season ripening, distinguished from its parents and other cultivars by specific traits, and maintained through asexual propagation methods like cuttings and grafting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing cultivars are used, then grapevine varieties are available, but they do not provide sufficient variation in berry characteristics such as color, shape, ripening date, and size

Engineering Contradiction:

Improveberry characteristic variationVSAvoidnumber of distinct varieties

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies parameter changes by systematically varying multiple berry characteristics simultaneously - color (dark red), shape (obtuse ovoid), size (large, 7.3g), and ripening date (early season, July 21) - to create a distinct variety that differs from existing cultivars in several parameters at once, thereby increasing berry characteristic variation and the number of distinct varieties available

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If new varieties are developed through controlled hybridization, then unique berry characteristics can be achieved, but the development process is time-consuming and complex

Engineering Contradiction:

Improveunique berry characteristicsVSAvoidhybridization process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing controlled hybridization between selected parent varieties (Sugrathirtyfive and Sugrafiftyfive) before the desired characteristics are needed, pre-establishing the genetic foundation for the new variety's unique berry characteristics - dark red color, obtuse ovoid shape, large size, and early ripening - thereby simplifying the subsequent development and propagation processes

Inventive Principle:

Principle #10Preliminary action

3Reliability

If asexual propagation is used to maintain variety characteristics, then true-to-type propagation is achieved, but the propagation process requires specific technical knowledge and conditions

Engineering Contradiction:

Improvetrue-to-type propagationVSAvoidpropagation process ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies copying by using asexual propagation methods (cuttings and grafting) to create exact genetic copies of the new variety SUGRA64, preserving its unique berry characteristics - dark red color, obtuse ovoid shape, large size, and early ripening date - without the genetic variation that occurs in sexual reproduction, thereby ensuring true-to-type propagation while maintaining the complexity of the propagation process through established technical protocols

Inventive Principle:

Principle #26Copying
