Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If plasma is generated and emitted from an emission port, then plasma processing can be performed on a target body, but visual verification of plasma application is not possible leading to potential misalignment
Solution Approach 1:
The patent employs a light emitting device that emits visible light in the same direction as plasma emission. This allows the operator to visually track the plasma beam path and confirm accurate application to the target body, resolving the contradiction by providing visual feedback through color/light changes without interfering with the plasma processing function.
Solution Approach 2:
The light emitting device serves as an intermediary element that does not directly participate in plasma generation but provides visual indication of plasma emission. This mediator allows operators to see the invisible plasma beam, enabling precise alignment and application while maintaining the integrity of the plasma processing system.
2Measurement precision
If a light emitting device is added to provide visual feedback, then plasma application accuracy improves, but device complexity increases
Solution Approach 1:
The light emitting device is integrated into the plasma generating device structure, allowing it to serve multiple purposes: providing visual feedback for plasma alignment and potentially assisting in defining the emission direction. This multi-functionality approach reduces overall system complexity compared to having separate independent systems.
Solution Approach 2:
The patent combines the light emitting device with the plasma emission system, positioning it to emit light in the same direction as plasma. This merging of functions into a single integrated system reduces the number of separate components and simplifies the overall device structure while achieving both plasma generation and visual feedback.

AI summary
Plasma emitting device 10 is provided with main body section 12, pair of electrodes 14 and 16, gas supply device 20, and laser emitting device 22. Gas supply device 20 supplies processing gas insider main body section 12. Then, voltage is applied to electrodes 14 and 16 such that electrical discharge occurs between electrodes 14 and 16, which causes the processing gas flowing inside cylindrical section 23 of main body section 12 to be plasmarized. Accordingly, plasma emitted from the opening on the end surface of cylindrical section 23 opposite to the end to which laser emitting device 22 is connected is emitted in an axial direction of cylindrical section 23. Also, laser emitting device 22 emits laser light in an axial direction of cylindrical section 23. Accordingly, due to the light, it is possible to visually check the plasma emission position, and it is possible to appropriately apply plasma to a target body.
