Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses struggle to effectively form structures on objects by irradiating them with processing lights, often resulting in incomplete or inaccurate surface modifications.
Innovation Solution
The proposed processing apparatus incorporates a light irradiation system with a partition member that surrounds the optical path between the object's surface and the optical member, allowing for precise control of the processing light's path and ensuring that the light is focused on the intended area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a processing light is irradiated onto a surface to form a structure, then the surface resistance is reduced and structure formation is achieved, but the positioning accuracy and structural precision are insufficient
Solution Approach 1:
The patent introduces a partition member that divides the processing space into multiple regions, including a light irradiation region and a substance collection region. This segmentation prevents processed substances from interfering with the optical path and positioning systems, thereby improving both structure formation precision and positioning accuracy simultaneously
Solution Approach 2:
The partition member acts as an intermediary element between the light irradiation area and the substance generation area. It allows the processing light to pass through while blocking and directing the processed substances away from the optical path, thus maintaining high precision in both positioning and structure formation without requiring complex additional systems
2Manufacturing precision
If processing light is used to form structures on object surfaces, then material removal or thickness modification is achieved, but substances generated by irradiation interfere with the optical path and reduce processing accuracy
Solution Approach 1:
The partition member extracts and isolates the harmful substances generated during light irradiation processing. By creating a separate collection region for these substances, the system removes the interference factor from the optical path while maintaining the beneficial effects of the processing light on the object surface
Solution Approach 2:
The partition member is positioned to preemptively block and redirect substances before they can enter the optical path. This preliminary action prevents optical interference from occurring, ensuring continuous high-precision processing without the need for complex real-time correction systems
