The existing electrochemical methods for evaluating physical properties of coating films, such as corrosion resistance, face challenges in adjusting measurement speed effectively, which hinders the speed-up of evaluation processes in paint plants and vehicle rust-proof quality improvement.
Innovation Solution
The method involves adjusting the temperature difference between the front and back sides of a measurement target object by using a rubber heater and a Peltier element to control the temperature of an electrolytic solution and the base material, respectively, to accelerate or decelerate the penetration speed of the electrolyte, thereby adjusting the measurement speed as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the measurement speed is increased to accelerate evaluation processes, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The patent applies dynamics by making the measurement process adaptable through temperature control. The system dynamically adjusts the penetration speed of the electrolytic solution by controlling the temperature difference between front and back sides, allowing the measurement conditions to be optimized for each specific evaluation scenario rather than using a fixed measurement speed.
Solution Approach 2:
The patent changes physical parameters (temperature of front side and back side) to control the penetration speed of the electrolytic solution. By adjusting the temperature difference between the two sides, the system can modify the measurement speed to achieve either faster evaluation or higher precision depending on the requirements.
2Measurement precision
If the measurement speed is decelerated to study electrochemical reaction mechanisms, then measurement precision is improved, but productivity deteriorates
Solution Approach 1:
The system enables dynamic adjustment of measurement conditions by controlling temperature parameters. When detailed electrochemical reaction mechanism study is required, the temperature difference can be reduced or reversed to slow down electrolytic solution penetration, allowing precise observation of reaction processes without permanently sacrificing evaluation speed capability.
Solution Approach 2:
By changing the temperature parameters (front side temperature and back side temperature), the system can control the penetration speed to match the specific measurement objectives. This parameter control allows the same system to serve both fast evaluation and detailed mechanism study requirements.
3Device complexity
If uniform temperature is applied to the measurement target object, then device complexity is reduced, but the ability to adjust measurement speed deteriorates
Solution Approach 1:
The patent segments the temperature control into two independent parts: front side temperature control and back side temperature control. This segmentation allows independent adjustment of each side's temperature, enabling precise control over the temperature difference and thus the penetration speed of the electrolytic solution, while maintaining relatively simple device structure.
Solution Approach 2:
The system applies local quality by creating different temperature conditions at different locations (front side versus back side) of the measurement target object. This local temperature differentiation enables control over the electrolytic solution penetration process without requiring complex overall system redesign.

AI summary
A physical property evaluation method is the method for evaluating physical properties of a film-shaped measurement target object by means of an electrochemical method, the method including the step of causing an electrolytic solution to contact a front surface of the measurement target object. The speed of penetration of the electrolytic solution into the measurement target object is adjusted in such a manner that the levels of the front-side temperature and the back-side temperature of the measurement target object and a difference between the front-side temperature and the back-side temperature of the measurement target object are adjusted.
