Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single laser needle is used for invasive treatment, then the treatment effect is improved compared to non-invasive methods, but the procedure time is extended and the overall treatment effect is reduced
Solution Approach 1:
The patent divides the single laser needle into multiple needle elements (at least three) arranged in an array. Each needle element can independently deliver laser energy to the target tissue, enabling parallel treatment of multiple areas simultaneously. This segmentation resolves the contradiction by maintaining the invasive treatment effect of individual needles while multiplying the overall treatment throughput.
Solution Approach 2:
The patent combines multiple laser needle elements into a single integrated handpiece that receives one laser beam from the optical cable. The laser beam is split and distributed to multiple needles, merging the functions of multiple treatment channels into one device. This combining approach improves procedure efficiency by treating multiple areas simultaneously while maintaining the reliability of invasive laser treatment.
2Reliability
If high-frequency laser beams are directly transferred to the target layer, then the treatment effect is enhanced, but the technical difficulty increases due to the challenge of direct transfer
Solution Approach 1:
The patent introduces optical lenses as intermediary components between the optical cable and the needle elements. The lenses (including focus lenses and convex lenses) act as mediators to couple the high-frequency laser beam from the optical cable to the needle elements, enabling efficient energy transfer. This intermediary approach resolves the technical challenge of directly transferring high-frequency laser beams while maintaining enhanced treatment effects.
Solution Approach 2:
The patent replaces complex mechanical coupling mechanisms with an optical system using lenses and optical cables to transfer laser energy. Instead of using mechanical contact or complex alignment mechanisms, the system uses optical field coupling through lenses to transfer high-frequency laser beams to multiple needle elements simultaneously, reducing device complexity while maintaining effective energy delivery.
3Power
If multiple lenses are installed in the handpiece to amplify the laser beam, then the laser beam energy is enhanced, but the device complexity increases
Solution Approach 1:
The patent designs the optical lenses in the handpiece to serve multiple functions: focusing the laser beam, coupling energy to the needle elements, and amplifying the laser energy before delivery. By making the lens system multi-functional, the patent enhances laser beam power without proportionally increasing device complexity, as the same optical components perform multiple critical functions in the energy delivery pathway.
