Solution Overview

Problem

Existing methods for improving corn yield and early vigor in corn plants are inadequate, as conventional bacteria strains do not effectively enhance yield or vigor, and there is a need for more efficient and targeted microbial applications.

Innovation Solution

The use of specific Methylobacterium isolates, such as ISO02, ISO03, ISO04, and ISO11, applied at various stages of corn development, either as a solid substance adhered thereto or in an emulsion, to enhance yield and early vigor by improving growth characteristics like height, leaf area, and root development.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional bacteria strains are applied to corn plants, then the application process is simple, but the yield enhancement and early vigor improvement are inadequate

Engineering Contradiction:

Improvecorn yieldVSAvoideffectiveness of yield enhancement

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and applying specific strains of Methylobacterium bacteria (such as strains ISO02, ISO03, ISO04, and ISO11) that have been characterized for their ability to enhance corn yield and early vigor. This involves changing the biological parameter from conventional bacteria to specifically identified Methylobacterium strains with proven efficacy, thereby resolving the contradiction between simple application and effective yield enhancement.

Principle #35Parameter changes

2Productivity

If specific Methylobacterium isolates are applied to enhance yield, then corn yield increases by 2-20%, but the complexity of identifying and selecting effective strains increases

Engineering Contradiction:

Improvecorn yieldVSAvoidstrain selection process

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent employs preliminary action by pre-identifying and characterizing specific Methylobacterium strains (ISO02, ISO03, ISO04, ISO11) that have demonstrated yield-enhancing capabilities in controlled studies. These strains are deposited in culture collections and made available for direct application, eliminating the need for users to perform complex strain selection processes while ensuring effective yield enhancement.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If Methylobacterium is applied at V6 to R3 development stage, then yield improvement is achieved, but the timing precision required for application increases

Engineering Contradiction:

Improvecorn yieldVSAvoidapplication timing

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent specifies a broad application window (V6 to R3 development stages) rather than requiring precise timing, which allows farmers to apply the Methylobacterium treatment during this extended period and achieve yield improvement without needing exact timing precision. This resolves the contradiction by providing flexibility in application timing while maintaining effectiveness.
