Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single high-power energy source is used to remove coating quickly, then productivity is improved, but the substrate may be damaged due to excessive energy
Solution Approach 1:
The system divides the coating removal process into two distinct stages using two separate energy sources: a first energy source (lower power) for initial coating removal and a second energy source (higher power) for complete removal. This segmentation allows each energy source to operate at an optimal power level appropriate for its specific task, preventing substrate damage while maintaining productivity.
Solution Approach 2:
The system dynamically adjusts the power levels of the two energy sources based on real-time feedback from sensors that detect coating thickness and removal progress. The controller modulates the energy output of each source according to the current state of the coating, enabling adaptive control that prevents substrate damage while maximizing removal efficiency.
2Object-affected harmful factors
If a single low-power energy source is used to protect the substrate, then substrate damage is prevented, but coating removal becomes inefficient
Solution Approach 1:
The system segments the energy delivery into two phases: the first energy source operates at lower power to safely remove the initial coating layer without risking substrate damage, while the second energy source operates at higher power to efficiently complete the removal process. This segmentation allows the system to achieve both substrate protection and high removal efficiency.
Solution Approach 2:
The system employs periodic action by alternating between two energy sources with different power levels. The first energy source is activated initially at lower power, and as coating removal progresses, the second energy source is activated at higher power to accelerate the process. This periodic switching optimizes both substrate protection and removal efficiency throughout the process.
3Manufacturing precision
If high power levels are used to remove thick coatings, then manufacturing precision is improved, but control difficulty increases
Solution Approach 1:
The system segments the power control into two distinct levels, each managed by a dedicated energy source. This segmentation simplifies the control complexity by assigning specific power levels to specific tasks: the first energy source handles lower power operations for initial removal, while the second energy source handles higher power operations for complete removal, making the overall control system more manageable.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors continuously monitor the coating removal process and provide real-time information to the controller. Based on this feedback, the controller automatically adjusts the power levels of both energy sources to maintain optimal removal conditions, thereby simplifying the control complexity while preserving manufacturing precision.

AI summary
A first source of radiation generates a first radiation to remove a coating from a component. An amount of the first radiation generated by the first source of radiation depends on an amount of power supplied to the first source of radiation. A controller receives feedback regarding removal of the coating from the component by the first radiation and regarding the amount of power supplied to the first source of radiation, and adjusts the amount of power supplied to the first source of radiation based on the feedback. A second source of radiation generates a second radiation capable of detecting whether the coating is encountered again. The controller restarts the first source of radiation to generate the first radiation in response to the coating being detected by the second radiation, and sets the amount of power supplied to the first source of radiation based on the feedback.
