Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a thermo-graphic camera is used to analyze laser irradiation distribution, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses a transparent plate that copies the laser irradiation pattern onto a photographable surface, allowing a standard camera to capture the distribution pattern that would otherwise require expensive thermo-graphic imaging equipment
Solution Approach 2:
A transparent plate serves as an intermediary medium between the laser beam and the camera, converting invisible infrared laser energy distribution into visible patterns that can be captured by standard imaging equipment
2Productivity
If laser treatment is performed by non-practitioners or inexperienced operators, then productivity is improved, but reliability deteriorates due to non-uniform energy transmission
Solution Approach 1:
The system provides immediate visual feedback by photographing and displaying the actual laser irradiation distribution pattern, allowing operators to self-correct and ensure uniform energy transmission without requiring extensive expertise
Solution Approach 2:
The evaluation system enables operators to independently assess and verify their own treatment quality through photographing and analyzing the laser distribution patterns, reducing dependence on highly skilled practitioners
3Use of energy by moving object
If laser intensity is increased to improve treatment effectiveness, then energy transmission is improved, but object-affected harmful factors increase due to excessive heat generation
Solution Approach 1:
The patent replaces thermal measurement methods with optical imaging to visualize laser distribution, enabling precise control of energy delivery to achieve effective treatment while avoiding excessive heat generation and associated side effects
