Solution Overview

Problem

The development of new hybrid corn varieties is a slow and costly process, and existing hybrid corn varieties lose commercial competitiveness over time, necessitating the creation of novel hybrids with improved characteristics such as high digestibility and adaptability to various production areas.

Innovation Solution

A new hybrid corn variety, designated 980005, is developed by crossing inbred varieties SLB01 and OOA25LY, which exhibits high digestibility, high tonnage, and expresses the 'Ly' or 'leafy' gene, along with enhanced yield and disease resistance, achieved through trait technologies and seed treatment options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional hybrid corn varieties are used, then they have maintained commercial competitiveness in the past, but they lose commercial competitiveness over time and require slow, costly breeding processes to develop new varieties

Engineering Contradiction:

Improvecommercial competitivenessVSAvoidbreeding process time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by introducing specific genetic modifications to the corn variety 980005, including the 'Ly' gene for increased leafiness and other trait technologies that alter plant characteristics to improve digestibility, yield, and adaptability, thereby maintaining commercial competitiveness without requiring lengthy traditional breeding processes

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If traditional hybrid corn varieties are used, then they have established performance characteristics, but they lack improved characteristics such as high digestibility and adaptability to various production areas

Engineering Contradiction:

Improveadaptability to production areasVSAvoidperformance consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent achieves universality by developing variety 980005 with multiple functional traits including high digestibility, high tonnage, the 'Ly' gene for increased leafiness, and enhanced adaptability to various production areas, allowing the single variety to perform reliably across diverse environments and uses

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If existing hybrid corn varieties are used, then they provide basic yield, but they lack enhanced yield and resistance to insects, weeds, and diseases

Engineering Contradiction:

ImproveyieldVSAvoidinsect, weed, and disease resistance

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies composite materials by integrating multiple trait technologies into variety 980005, combining genetic modifications for insect resistance, weed resistance, disease resistance, high yield, and high digestibility into a single composite variety that provides comprehensive protection and enhanced productivity

Inventive Principle:

Principle #40Composite materials
