Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Atmospheric pressure plasma generation devices cannot visually verify plasma application, leading to potential misalignment with processing targets, which may result in inadequate plasma application.
Innovation Solution
An information processing device calculates the plasma application position on a processing target object using captured image data from an imaging device, allowing for precise alignment with visible laser light guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plasma is applied from an atmospheric pressure plasma generation device, then plasma processing can be performed on the processing target object, but the plasma application position cannot be visually verified
Solution Approach 1:
The patent introduces visible light as an intermediary medium to enable visualization of the plasma application process. By superimposing visible light on the plasma discharge path, the system allows operators to visually track and verify the plasma application position in real-time, resolving the detection difficulty while maintaining plasma processing effectiveness
Solution Approach 2:
The patent utilizes color changes in the plasma discharge to make it visible. By introducing a visible light source that overlaps with the plasma discharge region, the system enhances the visual detectability of plasma application positions through color and light intensity variations, enabling real-time monitoring and precise position verification
2Device complexity
If no visual verification is provided, then the device structure remains simple, but plasma may not be appropriately applied to the processing target object
Solution Approach 1:
The patent implements a multi-functional system where the plasma generation device integrates both plasma discharge and visible light emission functions. This allows the same device structure to serve dual purposes: plasma processing and visual verification, thereby maintaining structural simplicity while achieving precise plasma application through real-time visual feedback

AI summary
In plasma irradiation device 20 of plasma application system 10, laser light 80 is emitted coaxially in an application direction of plasma. When plasma is applied to patient 12 from plasma irradiation device 20, the patient is imaged by imaging device 24, and an application position of the laser light on a processing target object, that is, plasma application position 82 is calculated by control device 22 based on captured image data. An image corresponding to the application position is displayed on display device 26. Accordingly, a clinician is able to recognize the application position of the plasma and it becomes possible to appropriately apply plasma to the patient.
