Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foreign substance removal is performed by stopping the shearing process, then cleaning effectiveness is improved, but productivity deteriorates
Solution Approach 1:
The guide unit rotates continuously during the laser shearing process, allowing one surface to guide the electrode while another surface is being cleaned by the cleaning unit. This continuous rotation eliminates the need to stop the shearing process for cleaning, maintaining both cleaning effectiveness and productivity
Solution Approach 2:
The guide unit is divided into multiple surfaces (first surface and second surface), allowing simultaneous execution of different functions on different surfaces. While one surface guides the electrode for shearing, another surface is cleaned by the cleaning unit, resolving the contradiction between cleaning and productivity
2Speed
If high-speed fluid flow is used to remove dust, then dust removal speed is improved, but electrode shaking increases
Solution Approach 1:
A dust removing unit with nozzles sprays high-speed fluid (15 m/s or more) to quickly remove dust generated during laser shearing. The fluid flow efficiently clears dust particles while the guide unit's rotation and positioning minimize electrode displacement
Solution Approach 2:
The guide unit rotates dynamically between guiding and cleaning states, and the dust removing unit applies controlled high-speed fluid flow that balances dust removal effectiveness with minimal electrode disturbance. The system adapts the fluid flow speed and direction to maintain electrode stability
