Solution Overview
Problem
Existing electronic smoking devices face inefficiencies in power management and operational modes, leading to unnecessary power consumption and battery drain, especially when not in use.
Innovation Solution
The electronic smoking device incorporates a power supply portion, atomizer/liquid reservoir portion, and control electronics that implement multiple power-saving modes, including a light sleep mode, low power sleep mode, and deep sleep mode, along with a communication mode and charge mode, to optimize battery life and reduce power usage when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the electronic smoking device operates in operation mode with frequent usage checks, then the device can respond quickly to user needs, but power consumption increases significantly
Solution Approach 1:
The control electronics dynamically adjust the device's operational state by implementing multiple sleep modes (light sleep mode, low power sleep mode, deep sleep mode) with different power consumption levels and check frequencies. The system transitions between these modes based on usage patterns, allowing rapid response when needed while conserving power during idle periods.
Solution Approach 2:
The device changes operational parameters by implementing different check frequencies for usage detection across various modes. During operation mode, checks occur frequently for rapid response, while in sleep modes, check frequency is reduced or extended, directly controlling power consumption based on the current operational state.
2Ease of operation
If the device performs frequent checks for usage during operation mode, then user experience is improved, but battery life is reduced
Solution Approach 1:
The control electronics implement periodic usage checks with varying periods depending on the operational mode. During operation mode, checks are performed more frequently to maintain good user experience, while in light sleep mode and low power sleep mode, the period between checks is extended, reducing power consumption while preserving essential functionality.
3Speed
If the device remains in operation mode to ensure immediate responsiveness, then user needs are met quickly, but unnecessary power is consumed during idle periods
Solution Approach 1:
The system dynamically adapts its responsiveness based on operational context. During operation mode, the device maintains high responsiveness with frequent checks. When transitioning to light sleep mode or low power sleep mode during idle periods, the check frequency is reduced, accepting lower responsiveness in exchange for significant power savings, as immediate responsiveness is not required during non-usage periods.
4Use of energy by moving object
If the device implements multiple sleep modes with reduced check frequencies, then power consumption is reduced, but the device may miss usage opportunities
Solution Approach 1:
The control electronics perform periodic checks for usage even during light sleep mode and low power sleep mode, albeit at extended intervals. This ensures that usage opportunities are not completely missed while maintaining reduced power consumption. The periodic nature of these checks balances power savings with sufficient usage detection capability.
