Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the antifouling ability of material surfaces are time-consuming and imprecise, as they either only measure hydrophilic or hydrophobic properties or require lengthy biofouling tests, leading to misleading results and high costs.
Innovation Solution
A method using a determining device with a probe and a spring characteristic structure, where a micro particle or micro particle with a pollutant adheres to the material surface, and the deformation of the spring structure is measured to determine the adhesion value, allowing for quick and accurate assessment of antifouling ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods (contact angle measurement, microbiological culturing, washing) are used to determine antifouling ability, then the evaluation can be performed, but the process is time-consuming and leads to misleading results
Solution Approach 1:
The patent replaces biological and chemical methods (microbiological culturing, contact angle measurement) with a mechanical measurement system. A probe with spring characteristic structure mechanically contacts the material surface, and the deformation of the spring structure directly measures adhesion force, eliminating the need for time-consuming biological culturing processes while providing precise quantitative data.
Solution Approach 2:
The patent uses a probe that replicates the adhesion interaction between foulants and the material surface. Instead of using actual microorganisms or complex biofilm formation processes, the probe creates a simplified copy of the adhesion phenomenon that can be measured directly and quickly, maintaining measurement relevance while drastically reducing evaluation time.
2Reliability
If ASTM gold standard verification method is used to evaluate biofouling, then comprehensive antifouling assessment is achieved, but the process requires soaking materials for weeks to months
Solution Approach 1:
The patent applies preliminary action by pre-coating the probe with substances that simulate foulant properties before contact with the material surface. This allows the adhesion measurement to directly reflect antifouling performance without requiring actual long-term biofouling formation, thus achieving reliable assessment in minutes rather than weeks or months.
Solution Approach 2:
The patent changes the measurement parameter from observing actual biofilm formation over time to measuring direct adhesion force. By transforming the evaluation from a time-dependent biological process to an immediate mechanical measurement, the patent maintains reliability while reducing the duration from weeks/months to minutes.
3Ease of operation
If contact angle method is used to measure surface properties, then hydrophilic or hydrophobic characteristics are determined, but the actual anti-sticking ability of dirt on surfaces cannot be measured
Solution Approach 1:
The patent introduces an intermediary probe that acts as a mediator between the measurement system and the material surface. The probe, coated with substances simulating dirt or foulants, directly experiences the adhesion interaction, providing accurate anti-sticking ability measurements while maintaining operational simplicity through automated probe contact and retraction mechanisms.

Function Achieved in This Case
This method rapidly and accurately determines the antifouling ability of material surfaces, reducing evaluation time from weeks or months to under 30 minutes and minimizing costs, while providing a direct and precise diagnosis of antifouling performance.
Implementation Method 1
deforming the spring characteristic structure until the probe departs from the material surface-to-be-determined to recover the spring characteristic structure
Implementation Method 2
contacting the probe with a material surface-to-be-determined to make the micro particle itself or the pollutant on the surface of the micro particle adhere to the material surface-to-be-determined
