Solution Overview

Problem

There is a need for a new raspberry variety that offers large fruit size, high brightness, a large number of branches, long canes, and good cold tolerance for the fresh market.

Innovation Solution

The development of a new raspberry variety, 'Stella', which is characterized by its large fruit size, high brightness, numerous branches, long canes, and good cold tolerance, achieved through vegetative propagation and selection from seed found in a fruit sorting facility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional raspberry varieties are used, then standard fruit size is achieved, but large fruit size for fresh market is not obtained

Engineering Contradiction:

Improvefruit sizeVSAvoidyield per hectare

Core Design Contradiction:

Volume of moving objectVSProductivity

Solution Approach 1:

The patent applies parameter changes by selecting and propagating plants with specific genetic parameters that result in larger fruit size (3cm length, 2.5cm diameter, 5.5g weight) while maintaining productivity through controlled vegetative propagation and optimized planting density

Inventive Principle:

Principle #35Parameter changes

2Illumination intensity

If conventional raspberry varieties are used, then standard brightness is achieved, but high brightness for fresh market appeal is not obtained

Engineering Contradiction:

Improvefruit brightnessVSAvoidcold tolerance

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting for specific visual parameters including high brightness (RHS N30A color) and strong glossiness, while simultaneously selecting for physiological parameters that provide cold tolerance for reliable winter production

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies preliminary action through pre-selection of plants exhibiting both high brightness and cold tolerance traits before vegetative propagation, ensuring that the propagated 'Stella' variety inherits these desirable characteristics reliably

Inventive Principle:

Principle #10Preliminary action

3Quantity of substance

If conventional raspberry varieties are used, then standard branching is achieved, but large number of branches with long canes is not obtained

Engineering Contradiction:

Improvenumber of branchesVSAvoidplant structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by selecting for specific structural parameters including cane length (172cm), internodal distance (7.0cm), and number of primocanes (three per plant), creating a standardized complex structure that is manageable despite its complexity

Inventive Principle:

Principle #35Parameter changes
