Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of pupil distance is used, then device simplicity is maintained, but adjustment precision and treatment efficacy deteriorate
Solution Approach 1:
The system uses an imaging unit to automatically capture eye images and analyze pupil positions, then the control unit autonomously calculates the required adjustment and drives the treatment unit to move, eliminating the need for manual adjustment while achieving high precision
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated system combining imaging, image processing, and motor-driven positioning, where the control unit processes visual data and translates it into precise mechanical movements of the treatment unit
2Productivity
If light wavelength is not optimized, then treatment coverage is maximized, but pupil contraction increases reducing light delivery efficiency
Solution Approach 1:
The patent specifically selects light wavelength as a controllable parameter, choosing the 380-420 nm range which has been determined to minimize pupil contraction while maintaining effective treatment, thereby optimizing the balance between treatment coverage and light delivery efficiency
3Measurement precision
If treatment unit position is not precisely adjusted, then device simplicity is maintained, but light alignment with pupils deteriorates reducing treatment efficacy
Solution Approach 1:
The imaging unit continuously monitors pupil position, and the control unit uses this feedback information to calculate and execute the necessary adjustments to the treatment unit position, creating a closed-loop control system that ensures precise light-pupil alignment
Solution Approach 2:
The imaging unit serves multiple functions: capturing eye images, analyzing pupil positions, determining pupil distances, and providing data for treatment parameter optimization, reducing the need for separate specialized components
