Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect pest detection methods using infrared rays face challenges such as high costs due to the need for multiple light emitting and receiving parts and increased detection errors due to dynamic range issues, especially when distinguishing small changes in light quantity from insect pests of varying sizes.
Innovation Solution
A detection apparatus and method that adjusts infrared ray intensity and temperature corrections to reduce static errors, allowing a single set of light emitting and receiving parts, and reduces detection errors by performing initial calibration to account for temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sets of light emitting part and light receiving part are used to detect objects at multiple paths, then object detection capability is improved, but device cost increases
Solution Approach 1:
The patent combines multiple detection paths into a single detection device by using a light receiving part that can receive light from multiple directions simultaneously. The light receiving part integrates the functionality of multiple separate detectors, allowing the system to detect objects at multiple paths without requiring multiple complete sets of light emitting and receiving parts, thus reducing device cost while maintaining detection capability
Solution Approach 2:
The light receiving part is designed to perform multiple detection functions simultaneously. It can detect objects at different paths and positions within the trap using a single detector, making the detection device universal and multi-functional rather than requiring specialized detectors for each path
2Adaptability or versatility
If dynamic range is increased to distinguish insect pests of various sizes, then detection coverage is improved, but detection precision deteriorates due to inability to distinguish small changes from errors
Solution Approach 1:
The patent implements a feedback mechanism where the detection result is used to adjust the light emitting intensity dynamically. When an object is detected, the system adjusts the light intensity to optimize the signal for that specific object size, allowing the system to maintain high precision across a wide range of insect pest sizes by continuously adapting to the detected target
Solution Approach 2:
The system dynamically adjusts the light emitting intensity based on detection needs rather than using a fixed intensity. This dynamic adjustment allows the system to optimize the light intensity for different object sizes, maintaining measurement precision while covering a wide dynamic range of insect pest sizes
