Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pest control methods, such as pheromonal and physical exclusion, face limitations in persistence and effectiveness against certain pest species, necessitating integrated strategies that combine pheromonal pest control with physical barriers like nets, while current pheromone dispensers are single-use and lack reusability.

Innovation Solution

Surface modification of polymers, such as polylactic acid, through solvent and coagulant treatments to create modified surfaces for physisorption of bioactive compounds, enabling reusable pheromone dispensers that act as both physical barriers and controlled release devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If pheromone is encapsulated in a membrane or solid matrix for continuous administration, then the pheromone can be released over time, but the dispenser becomes single-use and cannot be reloaded

Engineering Contradiction:

Improvepheromone release durationVSAvoiddispenser reusability

Core Design Contradiction:

Duration of action of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent employs porous polymer materials with controlled pore structures that allow pheromone molecules to diffuse through while maintaining the structural integrity of the dispenser. The porous nature enables both sustained release over time and accessibility for reloading, resolving the contradiction between duration and reusability

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The dispenser design allows the pheromone to be depleted and then recovered/replaced while keeping the dispenser structure intact. The polymer matrix maintains its functionality after pheromone release, enabling the same dispenser to be replenished and reused multiple times, thus converting a single-use system into a reusable one

Inventive Principle:

Principle #34Discarding and recovering

2Reliability

If exclusion nets are made with smaller mesh sizes to block pests like aphids, then pest exclusion effectiveness improves, but airflow through the mesh is limited

Engineering Contradiction:

Improvepest exclusion effectivenessVSAvoidairflow through mesh

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent applies different properties to different parts of the net structure. The mesh geometry is optimized locally to provide appropriate pore sizes for pest exclusion while maintaining adequate airflow channels. The pheromone treatment is applied specifically to the net surface rather than the entire structure, targeting pest behavior without compromising breathability

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If pheromone dispensers are designed as single-use devices, then manufacturing and distribution is simpler, but environmental sustainability and cost-effectiveness are reduced

Engineering Contradiction:

Improvedispenser manufacturing simplicityVSAvoidpheromone waste

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The dispenser is pre-loaded with pheromone during manufacturing in a straightforward process, maintaining ease of manufacture. However, the design enables the pheromone to be depleted and then replaced in the field, preventing waste by allowing multiple uses of the same dispenser structure and reducing the need to manufacture and distribute new dispensers repeatedly

Inventive Principle:

Principle #10Preliminary action
