Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ocular therapy devices for treating ocular tissue deformations with UV radiation are complex and costly, requiring precise adjustment for each patient, which complicates their use and increases expenses without optimizing beam properties for the patient's eye geometry.
Innovation Solution
The use of an etching diaphragm for energy distribution and an aspherical optical lens for beam shaping, along with multiple target beams and a fixation beam, allows for cost-effective and precise adjustment of the therapy beam to the patient's eye, improving handling and therapeutic effectiveness without altering the beam's properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional optical systems with multiple lenses and complex adjustment mechanisms are used, then beam properties can be controlled, but device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the essential function of beam control from complex multi-lens systems and implements it through a simplified optical bench with selective optical elements. Instead of using multiple lenses for each adjustment function, the invention selects specific optical elements (lenses, mirrors, prisms) placed at designated locations along the beam path to achieve the required beam properties with minimal components.
Solution Approach 2:
The optical bench serves as a universal platform that can accommodate various optical elements for different beam control functions. The same optical bench structure supports beam shaping, focusing, steering, and wavelength selection through interchangeable optical elements, eliminating the need for separate complex adjustment mechanisms for each function.
2Measurement precision
If precise adjustment mechanisms are implemented for each patient, then treatment accuracy improves, but ease of operation deteriorates due to complex adjustment procedures
Solution Approach 1:
The patent implements preliminary action by pre-configuring the optical bench with optical elements at specific locations optimized for different beam control functions. The optical elements are positioned in advance at designated locations along the beam path, so that when treatment is needed, the system is already prepared and requires minimal adjustment. The ocular adapter is also pre-configured with the patient's specific eye geometry parameters before treatment begins.
Solution Approach 2:
The system incorporates self-service features through the ocular adapter that automatically compensates for individual patient eye geometry variations. The adapter contains pre-determined correction values for common refractive errors, allowing the system to self-adjust for standard cases without requiring complex manual calibration by the operator.
3Ease of manufacture
If standard optical systems are used, then device cost is reduced, but adaptability to different patient eye geometries deteriorates
Solution Approach 1:
The patent implements dynamics by making the optical system adaptable through the ocular adapter, which can be configured for different patient eye geometries. The adapter allows the fixed-cost optical bench to dynamically adjust to individual patient requirements by incorporating patient-specific optical correction parameters, enabling the same hardware platform to serve diverse clinical needs without requiring custom-built systems for each patient.
