Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a constant electrical power output is delivered from the plasma source, then the device operation is simple, but the treatment result is suboptimal for surfaces with varying mesh sizes
Solution Approach 1:
The patent implements dynamic adjustment of the electrical power output from the plasma source based on detected surface properties. The control unit modifies power parameters in real-time according to mesh size detection, transforming the static power delivery system into a dynamic one that adapts to different surface conditions, thereby resolving the contradiction between operational simplicity and treatment quality.
Solution Approach 2:
The patent changes the electrical power parameters (voltage, current, or power level) of the plasma source based on detected surface mesh size. By adjusting these parameters dynamically, the system optimizes treatment effectiveness for different surface types while maintaining ease of operation through automated control, thus resolving the technical contradiction.
2Manufacturing precision
If a large electrical power output is used for treatment, then effective treatment is achieved on surfaces with small mesh size, but material wear and color change increase
Solution Approach 1:
The patent applies different electrical power outputs to different surface types based on their specific properties. By detecting mesh size and adjusting power accordingly, the system delivers locally optimized treatment - higher power for small mesh sizes where needed, and lower power for large mesh sizes where excessive power would cause damage, thus resolving the contradiction between treatment effectiveness and material preservation.
Solution Approach 2:
The patent implements a feedback mechanism where the surface properties (mesh size) are detected and this information is fed back to the control unit, which then adjusts the electrical power output accordingly. This closed-loop control prevents material damage by ensuring appropriate power levels are applied, resolving the contradiction between effective treatment and minimizing harmful effects.
3Manufacturing precision
If a large electrical power output is delivered to the plasma, then treatment of surfaces with small mesh size is effective, but energy loss increases for surfaces with large mesh size
Solution Approach 1:
The patent dynamically changes the electrical power parameters based on detected surface mesh size. For surfaces with large mesh sizes, the system reduces power output to avoid energy waste, while for small mesh sizes it increases power for effective treatment. This adaptive parameter adjustment resolves the contradiction between treatment effectiveness and energy efficiency.
Solution Approach 2:
The patent applies the principle of partial action by delivering only the necessary electrical power for effective treatment based on surface properties. Instead of always delivering maximum power, the system delivers partial power when sufficient (large mesh sizes) and full power only when necessary (small mesh sizes), thereby reducing overall energy loss while maintaining treatment effectiveness where needed.
