Surgical Light Independent Power Supply Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical lights often fail unexpectedly due to power supply issues, such as mains voltage loss and rapid accumulator discharge, posing risks during operations.
Innovation Solution
Incorporating a second lighting unit with an additional light source connected to a separate power supply line, allowing each unit to be powered independently from a distinct voltage source, ensuring continuous operation even if one power supply fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single power supply line is used for the surgical light, then the device complexity is reduced, but the reliability deteriorates due to unexpected failures during operations
Solution Approach 1:
The surgical light is divided into two independent lighting units (first lighting unit and second lighting unit), each with its own separate power supply line. This segmentation ensures that a failure in one power supply line does not affect the other, thereby improving operational reliability while maintaining manageable device complexity through modular design.
2Duration of action of moving object
If an accumulator is used to maintain operation during voltage loss, then the duration of action is extended, but the reliability deteriorates due to rapid discharge and complete failure
Solution Approach 1:
The patent incorporates an accumulator as a backup power source that is pre-charged and ready to take over immediately upon detection of mains voltage failure. This beforehand cushioning ensures continuous operation during and after voltage loss, extending the duration of action while maintaining reliability through the cushioning effect of the pre-prepared backup power source.
