Engineering Contradiction Analysis
1Measurement precision
If existing methods are used for measuring groundwater flow velocity and direction, then measurement can be performed, but measurement accuracy is low
Solution Approach 1:
The patent replaces complex mechanical measurement systems with an optical detection system. An infrared sensor module detects the position of an indicator influenced by water flow, and a processor module calculates velocity and direction based on detection data, eliminating the need for complex mechanical measurement mechanisms and improving both accuracy and ease of operation.
Solution Approach 2:
The patent introduces an indicator as an intermediary element that responds to water flow and whose position is detected by the infrared sensor. This intermediary enables indirect measurement of flow parameters, simplifying the overall measurement system while maintaining high accuracy through optical detection and computational analysis.
2Measurement precision
If existing methods are used for measuring groundwater flow velocity and direction, then measurement can be performed, but cost is high
Solution Approach 1:
The patent replaces expensive mechanical measurement instruments with a cost-effective optical system consisting of an infrared sensor module and a processor module. This substitution significantly reduces equipment costs while achieving high measurement accuracy through non-contact optical detection and computational methods.
Solution Approach 2:
The patent uses an optical signal (infrared detection of the indicator position) as a copy or representation of the physical water flow state. This allows measurement without direct mechanical interaction, reducing equipment complexity and cost while maintaining measurement accuracy through signal processing and calculation.
3Ease of operation
If existing methods are used for measuring groundwater flow velocity and direction, then measurement can be performed, but operational constraints are large
Solution Approach 1:
The patent replaces complex mechanical operation requirements with simple optical detection and automated processing. The infrared sensor automatically detects the indicator position, and the processor module automatically calculates flow parameters, eliminating complex operational steps and making the device easy to operate while maintaining high accuracy.
Solution Approach 2:
The patent implements automated detection and calculation functions where the infrared sensor module automatically detects indicator position and the processor module automatically computes velocity and direction from detection data. This self-service capability eliminates the need for complex manual operations while ensuring accurate measurements through systematic processing.
