Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrosion sensors face challenges in achieving precise measurement of corrosion loss due to insufficient initial thickness and width settings of the sensor portion, leading to inaccurate electric resistance value changes.
Innovation Solution
The method involves setting the initial thickness and width of the sensor portion to specific ratios relative to the maximum corrosion loss, ensuring the sensor portion is adequately larger than the maximum corrosion loss to prevent penetration and maintain precise measurement, with the width being at least 32 times the maximum corrosion loss and the initial thickness being at least twice the maximum corrosion loss, and the length optimized for improved measurement precision.

Engineering Contradiction Analysis
1Measurement precision
If the initial thickness of the sensor portion is increased, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies parameter changes by establishing specific mathematical relationships between the sensor portion dimensions and the maximum corrosion loss to be measured. Formula (I) defines tinit≥(2×tlimit) and Formula (II) defines w≥(32×tlimit), creating optimized dimensional parameters that ensure accurate measurement while avoiding excessive complexity. This systematic parameter optimization resolves the contradiction between measurement precision and device complexity.
2Measurement precision
If the width of the sensor portion is increased, then the measurement precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent optimizes the width parameter through Formula (II) w≥(32×tlimit), which establishes the minimum width required for accurate measurement. This parameter optimization ensures sufficient measurement precision while avoiding excessive material consumption and manufacturing complexity, thereby resolving the contradiction between measurement precision and ease of manufacture.
3Measurement precision
If the initial thickness of the sensor portion is set appropriately, then the measurement precision is improved, but the loss of substance increases
Solution Approach 1:
The patent applies parameter optimization through Formula (I) tinit≥(2×tlimit), which calculates the minimum initial thickness required for accurate corrosion loss measurement. This optimized parameter ensures sufficient measurement precision while minimizing material consumption, as the thickness is set to the minimum necessary value rather than being excessively large, thereby resolving the contradiction between measurement precision and loss of substance.

AI summary
A corrosion sensor is an electric resistance type corrosion sensor including a sensor portion exposed to an arbitrary environment and formed of an electric conductor, and a reference portion isolated from the arbitrary environment and formed of an electric conductor, and measuring a corrosion loss of the sensor portion based on an electric resistance value of the reference portion and an electric resistance value of the sensor portion. A width of the sensor portion is set to satisfy Formula (II): w≥(32×tlimit) . . . (II), tlimit: maximum corrosion loss to be measured [mm], and w: width of the sensor portion [mm].
