Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices with continuous light emitting modes for color detection waste power and shorten the life of the light source due to decreased luminous efficiency over time.
Innovation Solution
Implementing an intermittent light emitting mode for the light source in aerosol generating devices to reduce power consumption and extend the life of the light source by controlling the light source to emit light intermittently during at least part of the operating time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light source operates in continuous light emitting mode, then the color detection function is maintained, but power consumption increases and service life is shortened
Solution Approach 1:
The light source is controlled to emit light intermittently rather than continuously. The control unit activates the light source only when color detection is required, and keeps it off during periods when detection is not needed, thereby reducing overall power consumption while maintaining the necessary detection functionality.
2Reliability
If the light source operates in continuous light emitting mode, then the color detection function is maintained, but the service life of the light source is shortened
Solution Approach 1:
By implementing periodic operation where the light source is turned on only when needed for detection and turned off otherwise, the cumulative operating time is reduced, which directly extends the service life of the light source while maintaining adequate detection coverage.
3Measurement precision
If the light source operates in continuous light emitting mode, then detection accuracy is maintained, but luminous efficiency decreases over time
Solution Approach 1:
The intermittent operation reduces the total energy input to the light source, preventing the accumulation of energy-related degradation effects that reduce luminous efficiency over time, while still providing sufficient detection moments to maintain accuracy.
