Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for healthier food products that provide the nutritional benefits of legumes, such as high fiber and protein, low sugar and fat, and improved digestive and heart health, while ensuring a consistent crop supply, as legumes are underutilized in the US diet and obesity rates are high due to poor eating habits.

Innovation Solution

A pinto bean variety designated as GLEAM is developed, which can be used for breeding new bean varieties, characterized by its physiological and morphological traits, including slow darkening, good lodging resistance, and adaptability to machine harvest, retaining a bright white color under adverse conditions, and is deposited with the National Center for Genetic Resources Preservation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If legumes are promoted as healthy food to reduce obesity and improve nutrition, then health benefits and nutritional value are improved, but consistent crop supply is insufficient

Engineering Contradiction:

Improveconsistent crop supplyVSAvoidunderutilized in US diet

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The bean line GLEAM has been pre-developed with specific desirable traits (slow darkening, good lodging resistance, machine harvest adaptability) before deployment, ensuring consistent supply and performance when introduced to farmers and consumers

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If pinto beans are bred for slow darkening trait to maintain appearance quality, then color retention is improved, but genetic diversity may be reduced

Engineering Contradiction:

Improvecolor retentionVSAvoidgenetic variability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The slow darkening trait is targeted specifically at the seed coat color property without affecting other genetic characteristics, allowing selective improvement of color stability while preserving overall genetic diversity through controlled breeding programs

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If beans are bred for machine harvest adaptability, then ease of production is improved, but yield or quality traits may be compromised

Engineering Contradiction:

Improvemachine harvest adaptabilityVSAvoidcrop yield

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The GLEAM bean line integrates multiple functions: it possesses machine harvest adaptability through its growth habit and pod characteristics, while simultaneously maintaining good lodging resistance and slow darkening traits, achieving multi-trait optimization without sacrificing yield potential

Inventive Principle:

Principle #6Universality (Multi-functionality)
