Solution Overview

Problem

Current table grape varieties, such as 'Flame Seedless', suffer from inadequate natural color, berry size, and susceptibility to cracking, which affects their quality and market appeal.

Innovation Solution

The introduction of 'Stargrape 1', a new table grape variety with improved natural color, larger berry size, and reduced cracking susceptibility, achieved through asexual reproduction and grafting, addresses these issues by offering a distinct and stable cultivar.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional table grape varieties like 'Flame Seedless' are used, then they have been commercially available and established, but they suffer from inadequate natural color, smaller berry size, and susceptibility to cracking

Engineering Contradiction:

Improvecolor retention and cracking resistanceVSAvoidberry size uniformity and color quality

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by developing a new grape variety with fundamentally different genetic parameters that result in superior skin color intensity (187A vs 183A), larger berry dimensions (23-27mm length vs 18-19mm), and enhanced skin integrity that resists cracking. The asexual reproduction method preserves these improved parameters across generations.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses asexual reproduction through grafting to create identical copies of the selected grape plant. This copying process ensures that the superior traits (color, size, cracking resistance) are perfectly replicated across multiple generations and plants, maintaining true-to-type characteristics as confirmed by observations over successive generations.

Inventive Principle:

Principle #26Copying

2Reliability

If new grape varieties are developed to improve color and size, then quality and market appeal are enhanced, but the complexity of breeding and propagation increases

Engineering Contradiction:

Improvequality consistencyVSAvoidbreeding and propagation process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by first selecting a superior plant from open crosses based on desired traits (color, size), then immediately applying asexual reproduction through grafting to fix and propagate those traits. This preliminary selection and copying approach simplifies the overall process compared to continued sexual breeding, as it establishes a stable, true-to-type variety in one sequence of actions.

Inventive Principle:

Principle #10Preliminary action

3Stability of the object's composition

If asexual reproduction by grafting is used to maintain variety characteristics, then true-to-type consistency is achieved, but the process requires skilled horticultural techniques

Engineering Contradiction:

Improvevariety fidelityVSAvoidpropagation difficulty

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent applies self-service by using grafting to create self-sustaining propagation of the variety. Once the initial grafting is performed to establish the variety, the resulting plants can be propagated further through the same method, and the variety maintains itself true-to-type without requiring continuous intervention or complex breeding programs. The variety essentially propagates and stabilizes itself through this method.

Inventive Principle:

Principle #25Self-service
