Flying Insect Trap Using Negative Geotaxis and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flying insect trapping methods using aerosol sprayers or adhesive ribbons are ineffective due to insecticide contamination risks and unpleasant exposure to dead insects, and odor-based traps struggle with attracting flies without offending humans.
Innovation Solution
A flying insect trapping apparatus featuring a vertical surface or pendant attractive plate that utilizes negative geotaxis to guide insects into a trap chamber, eliminating the need for adhesives and offensive odors, and enhancing capture efficiency through specific plate shapes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive ribbons or sheets are used to trap flies, then flies can be trapped effectively, but dead fly bodies remain exposed causing unpleasant feelings and the adhesive may stick to user's hand or clothing
Solution Approach 1:
The invention places the adhesive ribbon inside a hollow spherical container, nesting the trapping mechanism within a protective enclosure. This allows the adhesive to remain effective for trapping flies while preventing dead insect bodies from being exposed to users and eliminating the risk of adhesive contacting hands or clothing.
Solution Approach 2:
The invention employs a disposable adhesive ribbon that is pre-attached to the inner surface of the spherical container. After use, the entire container with the used adhesive ribbon can be discarded or replaced, eliminating the need for cleaning or reusing the adhesive surface, thus avoiding exposure to dead insects and adhesive residue.
2Productivity
If attractant insecticide smell is made strong to attract flies, then attraction capability is improved, but the smell becomes offensive to human users
Solution Approach 1:
The invention concentrates the attractant insecticide at the bottom of the spherical container rather than distributing it throughout. This localized placement allows the smell to rise naturally through the container and disperse through small holes in the upper portion, providing effective attraction while limiting the concentration of offensive smell in the surrounding environment where users are present.
Solution Approach 2:
The invention uses vertical distribution of the attractant insecticide, placing it at the bottom of the container and allowing the smell to diffuse upward through the air space. This vertical dimension approach enables the attractant to reach flying insects effectively while the smell dissipates before reaching user-level concentrations.
3Productivity
If aerosol sprayer is used to control flies, then insecticide can be sprayed directly on flies, but insecticide may adhere to food and tableware in kitchen areas
Solution Approach 1:
The invention extracts the insecticide application function from direct spraying and replaces it with passive trapping. The attractant insecticide is contained within the spherical container and works by attracting and trapping flies that enter voluntarily, eliminating the need for active spraying that could contaminate food and tableware in kitchen environments.
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 apparatus achieves a higher capture rate of flying insects like flies and wasps without the drawbacks of conventional methods, providing a more effective and user-friendly solution for insect control.
Implementation Method 1
a flying insect is attracted by the member to land on the said surface portion thereof and then is induced to move along the surface portion and to pass through the said entry port

AI summary
A flying insect trapping apparatus is provided that is capable of attracting and trapping flying insects such as flies or wasps very well and moreover without giving a user an unpleasant feeling. The flying insect trapping apparatus comprises an attractive and inductive member (104,201) having a vertical surface portion, an entry port (101,203) surrounding an upper part of the attractive and inductive member; and a trap chamber (113) communicating with the entry port, whereby a flying insect is attracted by said member to land on said surface portion thereof and then is induced to move along the surface portion and to pass through said entry port so as to be trapped in the inside of said trap chamber.
