Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses face challenges in efficiently processing objects with complex shapes, particularly those with surfaces that are concave or have intricate geometries, as they struggle to accurately irradiate and measure these surfaces using traditional optical systems.
Innovation Solution
The processing apparatus employs a Galvano mirror and a meniscus-shaped optical member to change the irradiation position of processing light, allowing it to irradiate surfaces that intersect with a plane perpendicular to the optical axis, and includes a measurement system for precise alignment and measurement, enabling processing of complex shapes by adjusting the light concentration position based on the surface geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional optical system is used to irradiate object surfaces, then the system structure is simple, but it cannot accurately irradiate surfaces that are concave or have intricate geometries
Solution Approach 1:
The patent employs a movable optical member (such as a galvanometer-controlled mirror) that can dynamically change the irradiation position of processing light. This dynamic adjustment capability allows the optical system to adapt to various surface geometries including concave and intricate shapes, resolving the contradiction between adaptability and structural simplicity by introducing controlled mobility rather than complex fixed structures
Solution Approach 2:
The patent changes the irradiation approach by moving the optical member in spatial dimensions rather than complicating the optical path. By controlling the position of the optical member in X, Y, and Z directions, the system can irradiate complex surfaces from optimal angles without requiring complex optical components, thus improving adaptability while maintaining relatively simple device structure
2Adaptability or versatility
If the irradiation position is changed by moving optical members, then complex shapes can be processed, but mechanical restrictions may hinder the operation
Solution Approach 1:
The patent designs the optical member to serve multiple functions: it can change irradiation position, maintain optical alignment, and adapt to different surface geometries. This multi-functionality reduces the need for separate mechanisms for each function, simplifying the overall structure and improving ease of operation while maintaining high adaptability for processing complex shapes
Solution Approach 2:
The patent introduces an intermediary control system that coordinates the movement of optical members with the processing requirements. This intermediary layer (control system) manages the complexity of moving multiple optical components by providing centralized control, thereby easing the operational burden and preventing mechanical restrictions from hindering the system's ability to process complex geometries
3Manufacturing precision
If processing light is condensed on a condensed plane, then processing precision is improved, but the system cannot handle surfaces intersecting with the optical axis plane
Solution Approach 1:
The patent combines condensed light delivery with dynamic optical member positioning. The optical member can be moved to positions where it intercepts the condensed light from the first optical system and redirects it to irradiate surfaces including those intersecting with the optical axis plane. This dynamic redirection maintains processing precision while extending adaptability to complex surface geometries that traditional fixed condensed plane systems cannot handle
