Solution Overview

Problem

There is a need for new garden bean varieties that are stable, high-yielding, and agronomically sound, with improved traits such as heat tolerance, disease resistance, and adaptability to various growing conditions.

Innovation Solution

The development of the garden bean variety 'Memphis' (Phaseolus vulgaris L.), which includes methods for producing hybrid and transgenic plants with traits like herbicide resistance, insect resistance, and disease resistance, through crossing and backcrossing with specific traits, and the introduction of transgenes for improved characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional garden bean varieties are used, then they can be grown in standard conditions, but they lack heat tolerance and disease resistance

Engineering Contradiction:

Improveheat tolerance and disease resistanceVSAvoidadaptability to various growing conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by introducing transgenes that modify the genetic parameters of the garden bean variety. Specifically, transgenes conferring heat tolerance and disease resistance (such as Anthracnose and Halo blight resistance) are integrated into the genome, changing the biological parameters of the plant to enhance its reliability under stressful growing conditions while maintaining adaptability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If new traits are introduced through transgenes, then heat tolerance and disease resistance improve, but plant stability may be affected

Engineering Contradiction:

Improveheat tolerance and disease resistanceVSAvoidgenetic stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent employs preliminary action by carefully selecting and characterizing transgenes before their introduction into the garden bean variety. The transgenes are pre-tested for their ability to confer heat tolerance and disease resistance, and their integration is planned to minimize disruption to the existing stable genome. This preliminary preparation ensures that the genetic stability of the variety is maintained while achieving the desired improvements in reliability.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If hybrid and transgenic methods are used, then yield and adaptability improve, but the complexity of breeding increases

Engineering Contradiction:

ImproveyieldVSAvoidbreeding process complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent uses intermediaries in the form of carefully selected parent varieties and transgenic constructs that facilitate the breeding process. By using established breeding protocols with known parent lines and well-characterized transgenes, the complexity of the breeding process is managed systematically. The intermediary steps involve controlled crosses and selective breeding that streamline the introduction of desired traits while maintaining yield improvement and adaptability.

Inventive Principle:

Principle #24Intermediary (Mediator)
