Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If capacitively sensing devices are used to detect arthropods, then detection capability is provided, but ability to distinguish between different types of arthropods is lost
Solution Approach 1:
The patent segments the capacitance signal into multiple analytical dimensions (intensity, frequency, duration, type) to enable differentiation between arthropod types. By dividing the detection task into multiple signal characteristics rather than relying on a single capacitance measurement, the system achieves both detection capability and type differentiation precision.
Solution Approach 2:
The patent applies parameter changes by analyzing multiple characteristics of the capacitance signal (intensity, frequency, duration, type) rather than a single parameter. This multi-parameter approach allows the system to distinguish between different arthropod types while maintaining detection capability, directly resolving the technical contradiction.
2Measurement precision
If manual inspection methods are used to identify arthropod types, then accurate differentiation is achieved, but time consumption and labor requirements increase
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated electronic system that analyzes capacitance signal characteristics. The electronic processing device automatically differentiates arthropod types by evaluating signal intensity, frequency, duration, and type, eliminating the need for manual inspection while maintaining identification accuracy and significantly reducing time consumption.
Solution Approach 2:
The system enables self-service by allowing the detection device to automatically identify and differentiate arthropod types without human intervention. The electronic processing device independently analyzes the capacitance signals and determines arthropod types, freeing operators from manual inspection tasks while maintaining high accuracy.
3Adaptability or versatility
If general insect traps are used for monitoring, then broad pest coverage is achieved, but targeted detection of specific pest types is reduced
Solution Approach 1:
The patent implements multi-functionality by enabling the same capacitance detection device to both broadly detect various arthropod types and specifically identify particular pest species. The system analyzes multiple signal characteristics (intensity, frequency, duration, type) to achieve universal detection capability while simultaneously providing specific pest type identification through pattern recognition.
Solution Approach 2:
The patent applies local quality by using different signal analysis methods for different detection purposes. General capacitance changes provide broad arthropod detection coverage, while specific patterns in signal intensity, frequency, duration, and type provide targeted identification of specific pest types, allowing the system to optimize for different detection needs within the same device.
