Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing insect populations in stored grain, such as chemical pesticides and pheromone traps, are ineffective due to resistance development, environmental concerns, and limited longevity of pheromone sources, leading to significant financial losses and inefficiencies in pest control.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical pesticides and insecticides are used to reduce pest populations, then insect population control is improved, but harmful residues are left on grain and environmental damage occurs
Solution Approach 1:
The patent replaces chemical management systems with a physical/optical system using electromagnetic radiation at specific wavelengths (320-400nm UV range) to affect insect behavior. The excitation energy source (lamp or laser) generates photons that interact with insects without leaving chemical residues, substituting chemical action with electromagnetic field action.
Solution Approach 2:
The patent introduces electromagnetic radiation as an intermediary between the control system and insects. The excitation energy source produces photons that serve as the active agent to influence insect behavior, replacing direct chemical contact with indirect electromagnetic interaction.
2Reliability
If pheromone traps are used to control insect populations, then insect attraction is improved, but the longevity of the pheromone source is limited to approximately six weeks
Solution Approach 1:
The patent changes the fundamental parameter of the attractant from chemical pheromones with limited stability to electromagnetic radiation with controllable duration. By adjusting the operational parameters of the excitation energy source (lamp or laser), the system can maintain effectiveness indefinitely as long as power is supplied, overcoming the six-week limitation of pheromone degradation.
Solution Approach 2:
The patent substitutes the chemical pheromone system with an electromagnetic radiation system. Instead of relying on volatile chemical molecules that degrade over time, the system uses photons generated by an excitation energy source, which can be continuously replenished as long as electrical power is available.
3Reliability
If conventional pheromone traps are deployed in high densities to significantly reduce insect populations, then population control effectiveness is improved, but the cost and device complexity increase significantly
Solution Approach 1:
The patent creates a universal system that combines attraction and behavioral disruption in a single device. The excitation energy source performs multiple functions: attracting insects with UV radiation and simultaneously disrupting their navigation and behavior patterns, eliminating the need for multiple separate trap types deployed in high densities.
Solution Approach 2:
The patent adds a new dimension to insect control by using electromagnetic radiation wavelength (320-400nm) as the active control mechanism. This spectral dimension provides a more powerful and versatile means of affecting insect behavior compared to conventional single-function pheromone traps, achieving population reduction with fewer units.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively induces behavioral changes in insects, potentially reducing populations by attracting, repelling, or confusing them, thereby offering a longer-lasting and more efficient alternative to traditional pest control methods without the harmful side-effects of chemicals.
Implementation Method 1
The chemical compound may have one or more absorption bands at a set of absorption wavelengths and have one or more emission bands at a set of emission wavelengths. The excitation energy source may be configured to produce electromagnetic radiation at the absorption wavelengths so as to fluoresce the chemical compound and release photons at the emission wavelengths.
Implementation Method 2
The vapor-isolated vessel may be configured with at least one infrared transmissive window that is substantially transparent to the released photons at the emission wavelengths of the chemical compound.
