Solution Approach 1:

The patent replaces manual mechanical counting and recognition processes with an automated optical detection system. A light emitter projects light through a transit opening, and light detectors capture the light pattern to automatically identify and count insects based on their silhouettes, eliminating the need for manual trapping, recognition, and counting operations.

Inventive Principle:

Solution Approach 2:

The system enables self-service insect detection and counting through automated image processing. The light detectors and processor work autonomously to capture insect silhouettes, analyze the light blockage patterns, identify insect species, and generate population data without requiring human intervention in the detection and counting process.

Solution Approach 1:

The patent replaces labor-intensive manual field work with an automated optical system that can be deployed in remote locations. The system uses a light emitter, light detectors, and a processor to automatically detect and count insects, eliminating the need for researchers to physically access and manually process samples from hard-to-reach areas, thereby reducing deployment costs and complexity.

Inventive Principle:

Solution Approach 1:

The patent extracts only the essential optical components needed for insect detection: a light emitter and light detectors. By removing unnecessary complex sensors and optical elements, the system achieves adequate detection accuracy with minimal power consumption, suitable for battery-operated or remote deployments.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses simple, low-cost optical components (light emitter and detectors) rather than expensive complex sensors. These components consume minimal power and can be easily replaced if needed, making the system economically viable and energy-efficient for long-term deployment in remote locations.
