Single Power Button for Aerosol Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices face challenges with cumbersome, time-consuming, and power-consuming power settings adjustments, often requiring additional devices and lacking safeguards against accidental changes, which limits user control over aerosol generation and battery optimization.
Innovation Solution
A single power button on the aerosol-generating device allows users to change power levels by pressing the button a specific number of times within an engagement time period, with indicators displaying the current power level and battery charge, enabling on-device adjustments without additional devices and minimizing accidental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If additional devices (user interface device, docking station) are used to adjust power settings, then power settings can be adjusted, but the adjustment process becomes time-consuming and cumbersome
Solution Approach 1:
The aerosol-generating device enables users to adjust power settings directly on the device itself through a button press interface, eliminating the need for external user interface devices or docking stations. The device serves itself by providing all necessary controls and indicators integrated into the main unit, allowing immediate adjustment without synchronization steps or additional equipment.
2Adaptability or versatility
If additional devices are used for power settings adjustment, then power settings can be changed, but additional power is consumed for data transfer
Solution Approach 1:
The patent extracts the power settings adjustment functionality from external devices and relocates it directly to the aerosol-generating device. By removing the dependency on external user interface devices or docking stations for control functions, the system eliminates the power consumption associated with wireless or wired data transfer to and from external devices, while maintaining full adaptability of power settings.
3Ease of operation
If rotary switches or positionable switches are used for temperature selection, then power output can be adjusted, but accidental adjustments may occur
Solution Approach 1:
The patent implements a periodic action mechanism where the button must be pressed a specific number of times (e.g., three times) within a defined time window to effect a power setting change. This periodic repetition requirement acts as a deliberate action threshold that prevents accidental adjustments from single inadvertent button presses, while still allowing intentional adjustments when the user consciously presses the button the required number of times.
4Adaptability or versatility
If the aerosol-generating device is made very small to resemble a conventional cigarette, then user acceptance increases, but space for user interface and display devices is limited
Solution Approach 1:
The patent extracts the display and indicator functions from separate physical display devices and integrates them into the existing button structure. The same button used for power settings adjustment also serves as an indicator element, eliminating the need for additional display components. This extraction and elimination approach maintains the compact cigarette-like form factor while providing necessary user interface functionality.
5Ease of operation
If larger display devices or more display devices are added to the aerosol-generating device, then user interface capability improves, but battery power is consumed faster
Solution Approach 1:
The patent implements multi-functionality where the button serves dual purposes: as a control input for power settings adjustment and as an indicator element for displaying power levels and battery status. By making the button universal—serving both input and output functions—the system eliminates the need for separate display devices that would consume additional battery power, while maintaining comprehensive user interface capability.
