Solution Overview

Problem

Current cucumber cultivation methods are labor-intensive and costly, with existing varieties not suitable for high-wire cultivation due to rapid growth and long internodes, leading to inefficiencies in fruit yield and labor requirements.

Innovation Solution

Development of cucumber plants with the compact gene, which confers characteristics such as shorter internodes, smaller leaves, and a slower growth rate, allowing for higher plant density and improved suitability for high-wire cultivation and mechanical harvesting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional cucumber varieties are used for cultivation, then rapid growth and long internodes are achieved, but labor intensity increases and suitability for high-wire cultivation decreases

Engineering Contradiction:
Improvegrowth rateVSAvoidlabor intensity
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The patent applies parameter changes by modifying the genetic parameters of the cucumber plant through the compact gene. This gene alters key growth parameters including internode length, leaf size, and growth rate, transforming the plant from a conventional variety with long internodes and rapid growth to a compact variety with shorter internodes and moderated growth rate. This genetic parameter modification enables high-wire cultivation without excessive labor intensity.

Principle #35Parameter changes

2Length of stationary object

If conventional cucumber varieties with long internodes are cultivated, then plant structure is maintained, but plant density decreases and fruit yield per area reduces

Engineering Contradiction:
Improveinternode lengthVSAvoidfruit yield per area
Core Design Contradiction:
Length of stationary objectVSProductivity

Solution Approach 1:

The compact gene modifies the internode length parameter, reducing it from conventional lengths to shorter internodes. This parameter change allows more plants to be cultivated per unit area (higher plant density), which directly increases the total fruit yield per area despite each individual plant being slightly more compact.

Inventive Principle:
Principle #35Parameter changes

3Shape

If conventional cucumber varieties are used, then standard plant structure is maintained, but suitability for mechanical harvesting decreases

Engineering Contradiction:
Improveplant structureVSAvoidsuitability for mechanical harvesting
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

The patent changes multiple structural parameters simultaneously through the compact gene: internode length is shortened, leaf size is reduced, and overall plant architecture is modified. These parameter changes create a more open and compact plant structure that is mechanically accessible, enabling effective mechanical harvesting while maintaining a viable plant structure for support and fruit production.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If high plant density is implemented, then fruit yield per area increases, but labor intensity for cultivation increases

Engineering Contradiction:
Improvefruit yield per areaVSAvoidlabor intensity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The compact gene creates a plant with shorter internodes and smaller leaves, which modifies the spatial occupation of each plant. This parameter change allows higher plant density to be implemented without proportionally increasing labor intensity, because the compact structure reduces the time and effort required for cultivation operations such as pruning, harvesting, and maintenance.

Principle #35Parameter changes
