Medical Light Source Pulse Control for Synchronized Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing medical light source apparatuses face inconvenience due to the differing lifetimes of first and second light sources, which necessitate separate replacement times, disrupting the convenience of maintenance.
Innovation Solution
A medical light source apparatus with a first light source emitting white light and a second light source emitting near-infrared excitation light, where the light source controller controls pulse emissions such that the second light source emits less frequently than the first, reducing the lifetime difference and allowing for simultaneous replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the first and second light sources alternately emit light in a time division manner, then the usage time of both light sources is substantially the same, but the second light source needs to be replaced sooner due to its shorter lifetime, creating maintenance inconvenience
Solution Approach 1:
The patent applies periodic action by controlling the first and second light sources to emit pulse light in alternating periods. The light source controller ensures that the second light source emits less frequently than the first, creating a periodic emission pattern that aligns with the shorter lifetime of the second light source. This allows both light sources to be replaced at substantially the same time, improving maintenance convenience while maintaining balanced usage.
2Adaptability or versatility
If the first light source emits white light and the second light source emits excitation light, then both light sources can be used for different imaging purposes, but the differing lifetimes require separate replacement times, complicating maintenance
Solution Approach 1:
The patent uses periodic action to control the emission patterns of both light sources. By setting the second light source to emit less frequently than the first, the system maintains the versatility of having both white light and excitation light capabilities while synchronizing their replacement cycles. This reduces the complexity of managing different replacement times for different imaging functions.
3Duration of action of stationary object
If the second light source emits excitation light less frequently, then its lifetime consumption is reduced, but the total light emission for fluorescent imaging may be insufficient
Solution Approach 1:
The patent applies periodic action by implementing pulsed emission of the second light source at controlled intervals. The light source controller ensures the second light source emits less frequently than the first, extending its operational lifetime. The periodic emission pattern is designed to provide sufficient total light emission for fluorescent imaging while consuming less cumulative time, thereby extending the light source lifetime without significantly compromising imaging efficiency.
