Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing damage to plant roots from insect root herbivores are manual, labor-intensive, and destructive, limiting throughput and plant vigor, and there is a need for non-destructive, automated methods to evaluate the efficacy of insecticidal materials against corn rootworms.
Innovation Solution
Non-destructive imaging methods using X-ray computed tomography (CT) or magnetic resonance imaging (MRI) to assess root damage by obtaining images of plant roots infested with insect root herbivores, allowing for the generation of root nodal injury scores and evaluating the efficacy of insecticidal materials, which can be automated for high-throughput bioassays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual assessment and scoring methods are used to evaluate root damage, then human interpretation and training can be applied to assess root nodal injury, but the process involves considerable handwork, is labor-intensive, and may cause damage to plants through direct manipulation
Solution Approach 1:
The patent replaces manual mechanical assessment with automated imaging systems (X-ray, MRI, or optical imaging) that non-destructively capture root structures. Image processing algorithms automatically analyze the captured images to generate root nodal injury scores, eliminating the need for manual handling and visual inspection while maintaining or improving measurement precision and significantly increasing throughput capacity
Solution Approach 2:
The patent creates digital copies (images) of the root systems through non-destructive imaging techniques. These digital representations allow for repeated analysis without physical manipulation of the actual roots, enabling automated scoring algorithms to evaluate multiple parameters from the same copy and eliminating the need for destructive sampling
2Measurement precision
If manual root manipulation and washing is performed to assess root damage, then direct visual inspection of roots is possible, but plant vigor and agronomics may be compromised due to direct plant manipulation
Solution Approach 1:
The patent substitutes physical root extraction and washing with non-destructive imaging techniques that can visualize roots in situ within the soil matrix. X-ray and MRI imaging penetrate the soil to capture root structures without disturbing the plant-root-soil system, while optical methods use transparent containers to allow direct imaging, thereby maintaining plant vigor and ecological validity while achieving sufficient measurement precision
Solution Approach 2:
The patent introduces imaging technology as an intermediary between the researcher and the root system. Instead of directly manipulating roots through extraction and washing, the imaging system serves as a mediator that captures information about root condition non-invasively, allowing assessment of root damage while preserving plant integrity and vigor
3Measurement precision
If traditional manual scoring methods are used, then detailed human evaluation of root nodal injury can be performed, but automation and high throughput capability are limited
Solution Approach 1:
The patent replaces manual evaluation mechanics with automated image processing systems that use algorithms to detect, segment, and quantify root nodal injury from imaging data. These automated systems can evaluate multiple plants simultaneously or in rapid sequence, generating consistent root nodal injury scores without human interpretation variability while maintaining measurement precision through validated image analysis protocols
Solution Approach 2:
The patent creates digital copies of root systems through imaging that can be analyzed repeatedly by automated algorithms. These digital representations allow for automated feature extraction, pattern recognition, and injury quantification without requiring human reviewers to physically handle or re-examine samples, thereby enabling full automation while preserving the detailed evaluation capability
