Solution Overview
Problem
Existing pheromone diffuser technologies for agriculture face challenges such as high implementation and manufacturing costs, mechanical weakness, and poor isomeric purity affecting the efficacy of insect control, particularly in trellising and lifting crops, where devices need to withstand environmental conditions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pheromone diffusers are used, then insect control is achieved, but implementation costs and manufacturing costs are high
Solution Approach 1:
The patent combines the mechanical fixing function (trellising/lifting) with the pheromone diffuser function into a single integrated device. The polymer material serves dual purposes: providing mechanical strength for crop support and acting as a matrix for pheromone incorporation and release. This eliminates the need for separate diffuser devices, reducing implementation costs while maintaining insect control efficacy.
Solution Approach 2:
The device performs multiple functions simultaneously: it provides mechanical support for trellising or lifting crops, acts as a pheromone reservoir, and functions as a diffusion system. This multi-functionality reduces the number of separate devices needed, lowering both implementation and manufacturing costs while ensuring reliable insect control.
2Object-affected harmful factors
If biodegradable materials are used for diffusers, then environmental compatibility is improved, but mechanical strength is insufficient
Solution Approach 1:
The patent changes the purity parameter of the pheromone from conventional levels to ultra-pure (≥90% isomeric purity). This parameter change has an unexpected effect: it enhances the mechanical strength of the polymer material while maintaining environmental compatibility. The high purity pheromone molecules interact more favorably with the polymer matrix, creating a stronger composite structure that can serve both mechanical and diffuser functions.
Solution Approach 2:
The device uses a composite structure where ultra-pure pheromone is incorporated into a polymer matrix. This composite approach allows the material to exhibit both the biodegradability and environmental compatibility of natural materials and the mechanical strength required for trellising or lifting applications. The specific composition ratio and integration method create a material that satisfies both requirements simultaneously.
3Reliability
If pheromone impregnation is increased, then insect control efficacy is improved, but mechanical strength is reduced
Solution Approach 1:
The patent changes the purity parameter of the pheromone to ultra-pure levels (≥90% isomeric purity). This parameter change resolves the contradiction by allowing high pheromone content in the polymer matrix without significantly compromising mechanical strength. The high purity pheromone molecules create a more uniform distribution and stronger interactions within the polymer, maintaining structural integrity even at high impregnation levels.
Solution Approach 2:
The patent applies local quality by ensuring uniform distribution of ultra-pure pheromone molecules throughout the polymer matrix. This uniform local distribution prevents weak points or aggregation that would compromise mechanical strength, while still achieving high overall pheromone content for effective insect control. The consistent purity throughout the material ensures both efficacy and mechanical performance.
4Reliability
If isomeric purity is increased to ≥90%, then pheromone efficacy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent extracts only the essential active isomer components from the pheromone mixture, achieving ≥90% isomeric purity by removing inactive or less effective isomers. This extraction approach simplifies the manufacturing process compared to attempting to synthesize multiple isomers, as it focuses on producing and purifying a single dominant active component, thereby reducing manufacturing complexity while maximizing efficacy.
Solution Approach 2:
The patent changes the purity specification parameter from conventional levels to ultra-pure (≥90% isomeric purity). While this parameter change increases manufacturing requirements, it actually simplifies the overall process by eliminating the need for complex multi-component formulation and stability management. The single high-purity component is easier to manufacture, store, and integrate into the polymer matrix compared to maintaining stable mixtures of multiple isomers.
