Insect Barrier Using Electrode Electrical Field
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect repulsion methods, such as fly screens and electric field-based systems, fail to effectively prevent insects from passing through openings while maintaining sufficient air exchange and may harm insects or impair air circulation.
Innovation Solution
An insect repulsion and barrier system using at least two electrodes with different electrical potentials applied to create a permanent, cyclically changing, or intermittently present electrical field between them, which repels insects without harming them and allows for air circulation through openings or surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fine-meshed polyester or nylon mesh is used to prevent insects from passing through, then insect protection is improved, but air exchange is impaired
Solution Approach 1:
The invention extracts the insect-repelling function from the physical mesh structure and implements it through an electric field generated by electrodes. This allows the opening to remain physically open for air exchange while the electric field prevents insects from passing through, thus resolving the contradiction between insect protection and air exchange.
Solution Approach 2:
The invention replaces the mechanical barrier (fine-meshed screen) with an electric field-based system. Instead of using a physical mesh that blocks both insects and air, the electric field selectively repels insects while allowing air molecules to pass freely, thereby maintaining air exchange while providing insect protection.
2Device complexity
If a single electrode is used to generate an electric field for insect repulsion, then the structure is simple, but the electric field strength decreases with distance
Solution Approach 1:
The invention divides the electric field generation into multiple segments (at least two electrodes with different potentials) positioned at strategic locations. This segmentation allows the electric field to be maintained at effective strength across the entire opening area, preventing insects from finding weak points to pass through, while still maintaining relatively simple device structure.
3Reliability
If the mesh size is reduced to prevent small insects, then insect protection is improved, but air circulation is severely disturbed
Solution Approach 1:
The invention replaces the mechanical mesh barrier with an electric field that provides insect protection without physically obstructing air flow. The electric field repels insects based on their electrical properties while allowing air molecules to circulate freely, thus maintaining both insect protection and air circulation.
4Reliability
If fly protection devices are installed to prevent insects from passing through, then insect protection is improved, but the devices may harm insects or impair air circulation
Solution Approach 1:
The invention carefully controls the parameters of the electric field (voltage, frequency, waveform) to achieve insect repulsion without causing harm. By adjusting these parameters, the electric field creates a repulsive force that prevents insects from passing through while avoiding conditions that would cause injury or death to the insects, thus providing humane insect protection.
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 prevents insects from passing through openings or surfaces while maintaining air exchange and safety, using an electrical field strength suitable for repelling insects like mosquitoes without causing harm, thus forming an impenetrable barrier.
Implementation Method 1
The at least two electrodes are arranged in such a way that an electrical field is formed between the at least two electrodes in such a way that a permanent electrical field or a cyclically increasing and decreasing electrical field or an electrical field present at intervals with interruptions is generated. The permanent electrical field or the cyclically increasing and decreasing electrical field or the electrical field present at time intervals with interruptions, repels the insects approaching the electric field
