Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide is arranged at the periphery of the laser radiation part to suppress electrode vibration, then the electrode stability is improved, but the guide may suffer from dust adherence and potential damage
Solution Approach 1:
The harmful guide component is completely removed from the system. Instead of using a guide to suppress vibration, the invention extracts this component and replaces it with air flows that suppress vibration without the risk of dust adherence, thus resolving the contradiction between electrode stability and dust adherence.
Solution Approach 2:
The invention introduces air flows (pneumatic element) to suppress electrode vibration and remove dust. The air flows act on the electrode to stabilize it during laser processing while simultaneously carrying away dust particles, eliminating the need for a guide and avoiding dust adherence problems.
2Illumination intensity
If dust generated by laser radiation is scattered into the laser light path, then the light condensing property of the laser is deteriorated, but arranging a guide to suppress vibration may cause dust to stick to the guide
Solution Approach 1:
Air flows are introduced to perform dual functions: suppressing electrode vibration to maintain light condensing property and actively removing dust from the laser path. The pneumatic system replaces the guide, preventing dust adherence while maintaining laser beam quality.
Solution Approach 2:
The dust that would normally be harmful by sticking to guides or scattering laser light is converted into a removable contaminant by the air flows. The same air flows that suppress vibration also carry dust away from the laser path, transforming the dust problem into a manageable situation that benefits the overall process.
3Device complexity
If no guide is used during laser processing, then the device complexity is reduced, but the electrode may vibrate in the thickness direction due to reaction force from scattered dust
Solution Approach 1:
Instead of using a mechanical guide to suppress vibration, the invention employs air flows (pneumatic element) that provide vibration suppression without adding mechanical complexity. The air flows act on the electrode to stabilize it during laser processing, maintaining simplicity while achieving the desired stability.
Solution Approach 2:
The mechanical guide system is replaced with a pneumatic system (air flows). This substitution eliminates the need for mechanical contact and complex guide structures, reducing device complexity while effectively suppressing electrode vibration through aerodynamic forces.

Function Achieved in This Case
This approach effectively suppresses electrode vibration and maintains the light condensing property by stabilizing the electrode and removing dust, eliminating the need for guides that can be damaged by dust adherence.
Implementation Method 1
a first air flow configured to flow on one surface of the electrode and a second air flow configured to flow on the other surface of the electrode are formed
Implementation Method 2
the dust, such as fume, blows away by the air flows, and thus it is possible to suppress the reduction in the light condensing property of the laser light
