Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quality control of protective coating coverage on metallic electro-mechanical components is challenging due to complex surface shapes and limited visibility, and detecting operational corrosion is difficult due to poor contrast and access issues.
Innovation Solution
Incorporating fluorescent agents into protective coatings or added layers that act as bright contrast media under a light source, such as UV light, to identify imperfect or degraded coating areas by highlighting areas of no reflection compared to undamaged regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective coating is applied to metallic electro-mechanical components, then corrosion protection is improved, but quality control of coating coverage becomes difficult due to complex surface shapes and limited visibility
Solution Approach 1:
The patent applies fluorescent agents to the protective coating that cause the coating to emit light when exposed to UV irradiation. This color/ luminescence change enables easy visual detection of coating coverage, allowing inspectors to clearly see whether the coating is properly applied on complex surface shapes and in hard-to-see areas, thereby resolving the inspection difficulty while maintaining corrosion protection.
2Ease of operation
If conventional inspection methods are used for coating coverage, then inspection simplicity is maintained, but detection accuracy of imperfect coating and corrosion is poor due to limited contrast and visibility
Solution Approach 1:
The fluorescent agent causes the coating to luminesce under UV light, creating high contrast between coated and uncoated areas. This allows inspectors to easily identify imperfect coating coverage, spottiness, and corrosion with high accuracy while maintaining simple visual inspection procedures, thus resolving both ease of operation and measurement precision requirements.
3Device complexity
If traditional quality control methods are used for detecting operational corrosion, then no additional complexity is introduced, but detection reliability is low due to poor contrast and subjectivity at early corrosion stages
Solution Approach 1:
The fluorescent coating provides high-contrast visual indication of corrosion areas when exposed to UV light. Even at early corrosion stages, the contrast between the fluorescent coating and corroded metal surfaces enables reliable detection without requiring complex inspection equipment or subjective assessment, thus improving reliability while keeping the inspection system simple.

AI summary
The present disclosure provides assemblies, systems and methods of quality control and service inspection for metallic electro-mechanical components. More particularly, the present disclosure provides assemblies, systems and methods of quality control and service inspection for metallic electro-mechanical components (e.g., stator components) utilizing fluorescent agents. The present disclosure provides both (i) surface/assembly designs, and (ii) methods of their inspection. In the present disclosure, fluorescent agents can be mixed with protective and/or added layers to serve as bright contrast media under a light source (e.g., ultraviolet ("UV") light source). It is noted that in a case of imperfect coating or service corrosion, gaps in reflection can serve as clear indications of either inadequate quality or excessive corrosion-driven degradation of the components.
