Optical Inspection of Aerodynamic Surface Grooves Before Light Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing systems struggle to effectively process objects by irradiating their surfaces with processing light while ensuring that the object itself is not affected, particularly in forming structures that alter aerodynamic characteristics.
Innovation Solution
A processing system that includes an inspection apparatus for extraneous substance inspection and an irradiation apparatus to process the object's surface with processing light, along with a light reception apparatus to evaluate the formed structure's features using design information and output information from the light reception apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processing light is irradiated to form structures on the object surface, then aerodynamic characteristics are improved, but the object itself may be adversely affected
Solution Approach 1:
The inspection apparatus performs extraneous substance inspection and defect inspection before the irradiation apparatus processes the object surface. This preliminary inspection identifies suitable areas free of defects and extraneous substances, ensuring that only appropriate regions are subjected to processing light irradiation, thereby preventing adverse effects on the object while achieving the desired aerodynamic characteristics.
2Manufacturing precision
If extraneous substances are present on the surface, then processing quality deteriorates, but inspection time increases
Solution Approach 1:
The inspection apparatus integrates both extraneous substance inspection and defect inspection functions into a single integrated system. This merging of inspection functions allows simultaneous detection of both types of issues in one inspection pass, reducing total inspection time while ensuring processing quality by identifying all relevant surface conditions before irradiation.

AI summary
A method for inspecting a structure formed on a surface of an object and that changes an aerodynamic characteristic includes: optically receiving, by using a light receiver, light from the surface of the object on which the structure is formed; and evaluating a feature of the structure by using design information relating to the feature of the structure and output information from the light receiver. The structure on the surface of the object includes a plurality of concave structures each of which extends in a first direction along the surface of the object and which are arranged adjacent to each other in a second direction intersecting the first direction. The optically receiving includes optically receiving the light from the structure including the plurality of concave structures that have been irradiated with inspection light from a direction intersecting the first direction.
