3D Insect Control Sheet with Irregular Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling stored grain insect pests, such as fumigant treatments and insecticide spraying, are inefficient and labor-intensive, particularly in areas difficult to clean, like high places in food factories.
Innovation Solution
A three-dimensional insect control sheet with an irregular profile surface containing an insect growth regulator, specifically pyriproxyfen, is placed in areas where grain powder is likely to deposit, effectively inhibiting the hatching of eggs and growth of larvae.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fumigant treatment or insecticide spraying is carried out to control stored grain insect pests, then insect control effect is achieved, but food production ceases and time is lost
Solution Approach 1:
The invention applies insecticides in advance to the interior surfaces of food processing equipment and storage areas before insect infestation occurs. This preliminary treatment creates a residual protective layer that continuously releases insecticide, preventing infestation rather than treating it after occurrence, thereby avoiding production cessation.
Solution Approach 2:
The insect control system operates autonomously through residual insecticide release and monitoring sensors that automatically detect infestation levels. Once infestation is detected, the system triggers alerts or automated responses without requiring manual intervention, allowing continuous production while maintaining control.
2Object-affected harmful factors
If protective material is used to cover the food production line during insect control, then insecticide contamination is prevented, but cleaning time and labor are required after control
Solution Approach 1:
The insect control system applies insecticides locally to specific high-risk areas such as interior surfaces of equipment, corners, and crevices where infestation is most likely, rather than treating entire production lines. This localized approach minimizes the need for protective covering and subsequent cleaning of large areas.
Solution Approach 2:
The system uses food-safe, rapidly degrading insecticide formulations that break down into harmless substances within a short period. This eliminates the need for extensive cleaning and protective materials, as the insecticide itself becomes safe to leave in contact with food production surfaces.
3Reliability
If conventional insect control methods are used in hard-to-clean areas, then insect control is attempted, but effectiveness is reduced due to cleaning difficulties
Solution Approach 1:
The system applies insecticides in advance to hard-to-reach areas during scheduled maintenance periods when equipment is idle. The residual effect continues to provide protection during operation, eliminating the need for repeated access to difficult areas and maintaining effectiveness without compromising cleaning accessibility.
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 three-dimensional insect control sheet demonstrates a significant insect control effect on stored grain insect pests inside powder heaps, reducing the time and labor required for pest control and maintaining effectiveness even in hard-to-clean areas.
Implementation Method 1
containing an insect growth regulator, the insect growth regulator being contained at least in a front surface of the three-dimensional insect control sheet
Data Source
AI summary
An object is to provide a high insect control effect on larvae of stored grain insect pests that occur in a deposit of grain powder, which have been difficult to control by conventional insecticide application or fumigant treatment, and make it possible to easily carry out control even in places that are difficult to clean to remove grain powder. A three-dimensional insect control sheet (10) contains an insect growth regulator at least in a front surface (1a) and has a three-dimensional surface that forms a structure with an irregular profile. The front surface (1a) is at least part of the surface with the irregular profile.
