Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser irradiation is used for surface treatment, then coating removal efficiency is improved, but safety risk increases due to unintended light reflection
Solution Approach 1:
The patent employs detection processing units that monitor physical quantities (such as reflected light intensity) during laser irradiation. The control unit receives this feedback and adjusts laser parameters in real-time to prevent harmful reflections while maintaining treatment effectiveness. This closed-loop control system resolves the contradiction by dynamically balancing productivity and safety.
Solution Approach 2:
The patent introduces intermediary components including detection processing units and control units that act as mediators between the laser source and the workpiece. These intermediaries monitor the irradiation process and intervene when abnormal reflections are detected, thereby preventing harmful effects while preserving the beneficial coating removal function.
2Manufacturing precision
If laser power is increased to improve treatment quality, then irradiation effectiveness is improved, but safety risk and energy consumption increase
Solution Approach 1:
The patent implements dynamic control of laser power based on real-time detection of physical quantities during irradiation. Rather than using fixed high power settings, the system continuously adjusts laser parameters according to actual process conditions, achieving high treatment quality only when necessary while minimizing safety risks and energy consumption during normal operation.
Solution Approach 2:
The patent changes laser parameters (power, duration, wavelength) dynamically based on detected physical quantities and process conditions. By adjusting these parameters in real-time rather than maintaining constant high settings, the system achieves effective treatment quality while reducing unnecessary energy consumption and safety hazards.
3Reliability
If detection and control systems are added to improve safety, then safety and monitoring capability are improved, but device complexity increases
Solution Approach 1:
The patent designs detection processing units and control units that serve multiple functions: monitoring safety, measuring treatment progress, controlling laser parameters, and recording data. By making these components multi-functional rather than adding separate dedicated systems for each function, the patent improves safety while minimizing the increase in device complexity.
