Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high power laser is focused to increase energy concentration for effective tissue treatment, then treatment effectiveness is improved, but laser quality deteriorates due to ionization of adjacent air and suspended substances
Solution Approach 1:
The patent applies the inert environment principle by creating a vacuum environment within the light-transmitting member at the laser focusing position. This vacuum environment eliminates air and suspended substances that would otherwise be ionized by the high power focused laser, thereby preventing laser quality deterioration while maintaining the high energy concentration needed for effective tissue treatment.
2Reliability
If vacuum forming unit is added to prevent ionization and maintain laser quality, then laser quality is preserved, but device complexity increases
Solution Approach 1:
The patent merges the vacuum forming unit with the light-transmitting member structure, integrating the vacuum chamber, focusing elements, and light transmission function into a single unified component. This integration approach maintains laser quality through vacuum protection while avoiding the need for separate, complex vacuum systems, thereby minimizing the increase in device complexity.
Solution Approach 2:
The patent implements a nested structure where the focusing elements and vacuum chamber are integrated within the light-transmitting member. The vacuum forming unit is nested within the arm member structure, creating a compact hierarchical arrangement that reduces overall device complexity while maintaining the necessary vacuum environment for laser quality preservation.
