Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If temperature inside laser resonator is controlled using cold/hot water for maximum laser output efficiency, then laser output efficiency is improved, but device complexity increases due to temperature control system
Solution Approach 1:
The temperature control system is segmented into separate first and second temperature control parts, each independently controlling the temperature of first and second laser generators respectively. This allows independent optimization of each laser's temperature for maximum output efficiency while managing overall system complexity through modular control.
Solution Approach 2:
The system changes temperature parameters of laser generators using cold and hot water circulation to optimize laser output efficiency. By adjusting temperature as a key parameter, the system achieves maximum laser performance without requiring complex structural modifications.
2Object-affected harmful factors
If cooling gas is output to relieve pain after laser emission, then patient comfort is improved, but internal pressure control complexity increases
Solution Approach 1:
The pressure control system uses feedback from pressure sensors to automatically regulate the release of cooling gas. When internal pressure exceeds safe levels, the system detects this and automatically opens valves to release gas, providing pain relief while maintaining simple automatic control rather than complex manual regulation.
Solution Approach 2:
The cooling gas system is designed to automatically regulate its own pressure through integrated pressure sensors and control valves. The system self-manages the balance between providing pain-relieving cooling gas and maintaining safe internal pressure without requiring external intervention or complex control mechanisms.
3Productivity
If multi-wavelength lasers are emitted simultaneously or alternately for improved skin treatment effects, then treatment effectiveness is improved, but control precision requirements increase
Solution Approach 1:
The laser emission system is segmented into separate first and second laser generators operating at different wavelengths (1064 nm and 755 nm). Each laser can be controlled independently or in combination, allowing flexible treatment protocols with improved effectiveness while managing control complexity through modular architecture.
Solution Approach 2:
The system enables alternating emission of different wavelength lasers in periodic sequences, allowing optimization of treatment effectiveness for different skin conditions. The periodic switching between wavelengths provides precise control over energy delivery patterns while maintaining manageable control requirements through sequential operation.
