Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple aiming lasers with different colors are used, then tissue characterization capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple aiming lasers with different colors (e.g., blue, green, red) into a single integrated aiming laser assembly. This merging approach allows the system to excite different fluorophores in tissue simultaneously, improving tissue characterization capability while managing device complexity through unified control architecture and integrated optical paths.
Solution Approach 2:
The aiming laser assembly is designed to serve multiple functions: it acts as both an aiming guide for the surgical laser and as an excitation source for fluorescent sensing. By making the aiming lasers multi-functional, the system improves measurement precision without proportionally increasing device complexity, as the same components serve dual purposes.
2Manufacturing precision
If real-time monitoring and control systems are added, then surgical precision and safety are improved, but device complexity increases
Solution Approach 1:
The patent implements real-time feedback loops where sensors monitor tissue characteristics and thermal conditions during surgery, and the controller continuously adjusts surgical laser parameters based on this feedback. This feedback mechanism improves surgical precision and safety by enabling dynamic adaptation to tissue responses, while the automated control reduces the need for complex manual intervention systems.
Solution Approach 2:
The system incorporates automated control algorithms that enable the laser system to self-regulate its operation based on sensor inputs. The controller automatically adjusts pulse width, energy, and timing parameters without requiring constant manual intervention, thereby improving precision while managing complexity through automation rather than additional manual control mechanisms.
3Object-affected harmful factors
If pulse width and energy per pulse are precisely controlled, then tissue damage risk is reduced, but control system complexity increases
Solution Approach 1:
The patent employs precise control of critical laser parameters including pulse width, energy per pulse, and repetition rate. By implementing fine-grained parameter control with high-resolution adjustment capabilities, the system can optimize laser-tissue interaction to minimize damage risk. The controller manages these parameters through digital control interfaces that allow precise setting and monitoring, reducing complexity through standardized control architecture.
