Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic aerosol provision systems lack an efficient and power-conserving method to indicate battery power level to users, often consuming unnecessary power by continuously illuminating indicators.
Innovation Solution
A system with an indicator light that emits a light signal after detecting the completion of a puff period, indicating the battery's power level, using pulse width modulation to conserve power and provide real-time updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the indicator light is activated continuously to show battery power level, then the user can always know the power status, but the battery power is consumed faster
Solution Approach 1:
The indicator light is activated periodically at predetermined intervals rather than continuously. The controller is configured to activate the indicator light to emit the light signal for the signal period at a series of predetermined intervals, which reduces continuous power consumption while still providing regular updates to the user about battery status.
Solution Approach 2:
The system automatically activates the indicator light based on detected usage patterns. The controller detects when a puff period has been completed and automatically activates the indicator light without requiring user intervention, making the system self-serve the information provision function.
2Loss of information
If the indicator light is activated after every puff period to show real-time power level, then the user gets frequent updates, but the battery power is consumed faster
Solution Approach 1:
The indicator light is activated at predetermined intervals rather than after every single puff. This periodic activation provides regular updates to the user while limiting the total activation time, thereby extending battery operating duration.
Solution Approach 2:
The system provides partial information updates by activating the indicator light only at selected intervals rather than continuously after every puff. This partial action is sufficient to keep users informed about battery status while significantly reducing power consumption compared to continuous activation.
3Use of energy by moving object
If the indicator light is not provided, then the battery power is conserved, but the user cannot know when the battery is exhausted
Solution Approach 1:
The system automatically detects puff periods and activates the indicator light without user intervention. This self-service approach ensures reliable battery status indication is provided when needed while minimizing unnecessary power consumption.
Solution Approach 2:
The indicator light provides feedback to the user about battery status at regular intervals. This feedback mechanism ensures users are informed about battery levels without requiring continuous power consumption, as the system provides periodic updates rather than continuous information.
