Solution Overview
Problem
Existing pest detectors rely on adhesive sheets, which become ineffective over time and require frequent replacement, leading to increased maintenance and size constraints due to the need for longer adhesive sheets and larger devices.
Innovation Solution
A pest detector using counter electrodes with an electric field generator and an imager to attract and image insect pests without an adhesive sheet, allowing for continuous operation and flexible installation without the need for adhesive sheet replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an adhesive sheet is used to capture insect pests, then the occurrence status of insect pests can be determined, but the adhesive sheet becomes covered with pests over time and requires frequent replacement
Solution Approach 1:
The patent replaces the mechanical adhesive capture system with an electrostatic field-based capture system. Instead of using adhesive sheets that physically stick to pests, the invention uses electrodes to generate electrostatic fields that attract and capture insects, thereby eliminating the need for periodic adhesive sheet replacement while maintaining reliable pest detection capability
Solution Approach 2:
The patent changes the fundamental parameter of pest capture from chemical adhesion to electrostatic attraction. By applying voltage to electrodes, the system creates electrostatic fields that attract insect pests, allowing for continuous operation without the degradation issues inherent in adhesive materials
2Loss of time
If the adhesive sheet replacement time is increased to reduce replacement work, then maintenance effort decreases, but the adhesive sheet length and device size increase
Solution Approach 1:
The patent replaces the mechanical adhesive sheet system with an electrostatic field system using electrodes. This substitution eliminates the need for long adhesive sheets and periodic replacement, as the electrostatic field can be continuously maintained without degradation, thereby reducing both replacement time and device dimensions
3Productivity
If the adhesive sheet length is increased to extend replacement intervals, then replacement frequency decreases, but the device size increases and installation positions are restricted
Solution Approach 1:
The patent substitutes the adhesive sheet mechanism with an electrostatic field generation system. The electrodes can generate sustained electrostatic fields without the physical constraints of adhesive sheet length, enabling extended operational intervals without increasing device volume, thus maintaining high productivity without restricting installation positions

AI summary
A pest detector includes: a first electrode; a second electrode that is arranged to face the first electrode; an electric field generator that generates an electric field in a gap between the first electrode and the second electrode; an imager that images at least the first electrode; and a hardware processor that determines an attaching state of insect pests that can be attached to the first electrode, based on an image captured by the imager.
