Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed pulse energy beam is used for treatment, then the treatment process is simple, but treatment efficiency deteriorates because the beam energy is not suitable for different ocular tissues
Solution Approach 1:
The patent applies preliminary action by performing a test irradiation before the actual treatment irradiation. The control unit first radiates a test beam with a specific pulse energy to the treatment region, detects bubble generation, and determines the suitable pulse energy level before proceeding with the main treatment beam radiation. This preliminary testing phase ensures that the subsequent treatment uses optimally adjusted energy parameters.
Solution Approach 2:
The patent implements feedback by using a bubble detection unit to monitor bubble generation during beam irradiation. The control unit receives detection results and adjusts the pulse energy of subsequent beams based on this feedback. When bubbles are detected, the system modifies the beam energy parameters, creating a closed-loop control system that continuously optimizes treatment parameters based on real-time tissue response.
