Solution Overview

Problem

Existing compositions fail to address the decrease in photosynthetic capacity caused by reactive oxygen species (ROS) in plants under abiotic stress, such as high or low temperature, salt, and drying conditions.

Innovation Solution

A composition comprising peptide-based and sugar-based biosurfactants, along with an agriculturally acceptable carrier, is used to suppress the generation of ROS, thereby maintaining photosynthetic capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plants are exposed to abiotic stresses (high temperature, low temperature, salt, drying), then environmental stress resistance is improved, but photosynthetic capacity decreases due to ROS generation

Engineering Contradiction:

Improveenvironmental stress resistanceVSAvoidphotosynthetic capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies biosurfactants to convert the harmful effect of ROS into a beneficial outcome. The biosurfactants reduce ROS generation, thereby protecting photosynthetic capacity while maintaining stress resistance. This transforms the harmful ROS byproduct of stress exposure into a manageable condition through biochemical intervention.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The biosurfactant acts as an intermediary substance between the plant and the abiotic stress conditions. It mediates the interaction by reducing ROS generation at the cellular level, thereby protecting the photosynthetic apparatus without eliminating the stress exposure itself. This allows the plant to maintain both stress resistance and photosynthetic function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If biosurfactant is added to reduce ROS, then photosynthetic capacity is maintained, but composition complexity increases

Engineering Contradiction:

Improvephotosynthetic capacityVSAvoidcomposition complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent utilizes parameter changes in the biosurfactant concentration to achieve effective ROS reduction. By optimizing the concentration range (0.001-10% by mass), the composition maintains photosynthetic capacity without requiring complex formulation strategies. The simple parameter adjustment of biosurfactant dosage provides an elegant solution to the contradiction.
