Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing apparatuses face challenges in accurately and efficiently processing complex-shaped workpieces with internal recesses, as they often require movable members like Galvano mirrors, which can limit processing accuracy and speed due to mechanical constraints.
Innovation Solution
The processing system employs a configuration where the processing head includes a conical mirror and a shape change optical system, allowing the processing light to be directed and focused within internal spaces without a movable member at the head's end, enabling precise processing of complex shapes by adjusting the optical system's position and orientation relative to the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If movable members like Galvano mirrors are used to direct processing light, then the processing apparatus can handle complex-shaped workpieces, but the mechanical constraints limit processing accuracy and speed
Solution Approach 1:
The patent replaces the mechanical Galvano mirror system with an optical solution using a fixed conical mirror and a deformable mirror. The deformable mirror uses electrostatic actuation to change its surface shape, directing the processing light without mechanical movement of the entire mirror assembly. This substitution eliminates mechanical constraints while maintaining the ability to handle complex workpiece geometries.
Solution Approach 2:
The patent implements a dynamic optical system where the deformable mirror can change its surface configuration in real-time through electrostatic actuation. This allows the system to adapt to different complex workpiece shapes and internal recesses without mechanical movement, achieving both versatility and high precision by controlling the mirror surface shape dynamically rather than moving the mirror itself.

3Manufacturing precision
If a fixed optical system is used without movable members, then processing accuracy and speed improve, but the ability to access internal recesses of workpieces is limited
Solution Approach 1:
The patent introduces a third dimension to the optical system by using a conical mirror with a specific apex angle. This conical geometry allows the processing light to be directed at various angles relative to the workpiece surface, enabling access to internal recesses and complex geometries. The light can propagate in multiple directions from the fixed optical system, effectively adding angular dimensionality without mechanical movement.
Solution Approach 2:
The patent changes the optical parameters by using a deformable mirror that can alter its surface curvature and shape. By changing the mirror surface parameters through electrostatic actuation, the system can focus and direct the processing light to different locations and angles, enabling access to internal recesses while maintaining a fixed physical position. This parameter control provides the adaptability needed for complex workpieces.
