Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current red raspberry cultivars lack a variety that consistently produces two crops per year with firm, light red fruits that are easy to pick and maintain stable flavor and color throughout the season, while also being resilient to varying temperatures and adaptable for diverse propagation methods.

Innovation Solution

The 'Atena' cultivar, derived from crossing 'Dolomia Plus' and 'Erika', exhibits strong vigor, upright canes, and produces very firm light red fruits that are easy to pick, with two crops per year, primarily ripening on current season's cane in autumn, and can be propagated through root cutting and tissue culture, offering improved adaptability and productivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If current red raspberry cultivars are used, then fruit production is maintained, but the fruits lack firmness and are difficult to pick

Engineering Contradiction:

Improvefruit firmnessVSAvoidease of fruit picking

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent applies parameter changes by selecting and propagating plants with specific genetic parameters that result in very firm fruits. The cultivar 'Atena' was developed through controlled crossing and selection processes that fixed the firmness parameter, making fruits easy to pick while maintaining quality.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If single crop per year is produced, then plant management is simplified, but productivity is reduced

Engineering Contradiction:

Improvenumber of crops per yearVSAvoidplant management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements continuity of useful action by enabling two crops per year through proper plant management. The cultivar 'Atena' produces a first crop on current season's cane in autumn and a second crop on old canes in spring, maintaining continuous fruit production without requiring complex intervention.

Inventive Principle:

Principle #20Continuity of useful action

3Stability of the object's composition

If fruits ripen on current season's cane, then flavor and color stability is improved, but harvesting timing becomes more critical

Engineering Contradiction:

Improveflavor and color stabilityVSAvoidharvesting time sensitivity

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by ensuring that current season's canes are properly developed and prepared before fruit ripening. The plant management protocol includes preliminary care for cane development and fruit set, which ensures stable flavor and color while allowing for scheduled harvesting.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If traditional propagation methods are used, then propagation is simple, but adaptability to different conditions is limited

Engineering Contradiction:

Improveadaptability to different conditionsVSAvoidpropagation difficulty

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent implements universality by developing a propagation system that works across multiple methods (root cutting, tissue culture, suckers) and environmental conditions. The cultivar 'Atena' can be propagated through various techniques while maintaining stable characteristics, making it adaptable to different growing conditions and propagator preferences.

Inventive Principle:

Principle #6Universality (Multi-functionality)
