Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing endoilluminator systems are used, then the system structure is simple, but the output calculation accuracy is insufficient
Solution Approach 1:
The patent segments the endoilluminator system into distinct functional components: illuminator contribution (light source, optics, attenuators) and fiber contribution (optical fibers, connectors). Each segment has its own calibration factors and efficiency parameters, allowing independent measurement and calculation. This segmentation enables accurate output calculation by multiplying the illuminator contribution by the fiber contribution, resolving the contradiction between measurement precision and device complexity.
2Stability of the object's composition
If lamp performance degradation is not monitored, then the system operation is simple, but the output consistency deteriorates over time
Solution Approach 1:
The patent implements preliminary calibration of the lamp performance degradation factor during manufacturing or initial setup. This pre-determined factor is stored and automatically applied during operation to compensate for expected lamp aging and performance degradation. By performing this calibration action in advance, the system maintains output consistency over time without requiring complex real-time monitoring or adjustment mechanisms, thus resolving the contradiction between stability and ease of operation.
3Measurement precision
If multiple calibration factors are used, then the measurement accuracy improves, but the calculation complexity increases
Solution Approach 1:
The patent implements self-service through automated calculation algorithms that multiply the calibrated illuminator contribution factor by the calibrated fiber contribution factor to determine the endoilluminator output. The system automatically selects and applies the appropriate calibration factors based on the specific components used, eliminating the need for manual calculations or complex measurement procedures. This automation maintains high measurement precision while reducing calculation complexity and user burden.

AI summary
In certain embodiments, determining an endoilluminator output includes calculating an illuminator contribution of an endoilluminator system and a fiber contribution of one or more optical fibers of the endoilluminator system. The endoilluminator output is determined from the illuminator contribution and the fiber contribution. The illuminator contribution may be established using calibrated or empirically determined factors, such as an illuminator leg efficiency, an attenuator factor, an initial lamp performance, and/or a lamp performance degradation factor of the lamp. The fiber contribution may be established using calibrated or empirically determined factors, such as a fiber coupling factor and/or fiber transmission ratio of the optical fibers.
