Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic vapour provision devices, such as electronic cigarettes, face challenges in power management, as they often consume unnecessary energy when not in use, leading to reduced battery life and increased energy wastage before the device is activated by a user.
Innovation Solution
The integration of a computer processor and memory in the battery assembly that detects the connection state of the vaporiser, allowing the device to enter a low power sleep mode until the vaporiser is connected, thereby conserving power and ensuring sufficient energy for immediate use without manual charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the device remains active to ensure immediate readiness for use, then the response time is improved, but the power consumption increases
Solution Approach 1:
The system dynamically transitions between sleep mode and connected mode based on vaporiser connection status. The computer processor adjusts its operational state in real-time, switching from a low-power sleep state to a higher-power connected state when the vaporiser is detected, thereby optimizing the balance between response time and power consumption
Solution Approach 2:
The system changes the operational parameters of the computer processor based on detection results. When the vaporiser is connected, the processor transitions from sleep mode with minimal power consumption to connected mode with higher power availability, effectively adjusting system parameters to match operational requirements
2Productivity
If the device is kept in a higher power state to enable rapid activation, then the productivity is improved, but the energy wastage increases
Solution Approach 1:
The system performs preliminary detection of the vaporiser connection status and pre-positions itself in connected mode in advance of actual use. By detecting the connection state before the user activates the device, the system can prepare the power cell and computer to be immediately ready, eliminating activation delay without requiring continuous high-power operation
Solution Approach 2:
The system employs periodic detection of vaporiser connection status and transitions between operational modes accordingly. Rather than maintaining continuous high-power state, the system periodically checks connection status and activates higher power consumption only when needed, creating a rhythmic pattern of low and high power states that reduces overall energy wastage
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables the device to remain active with minimal power consumption, ensuring it is ready for use upon connection of the vaporiser, reducing energy wastage and extending battery life by maintaining a low power state until activation.
Implementation Method 1
The battery assembly may further comprises a capacitor; wherein the computer is configured to first charge the capacitor and then detect whether a vaporiser is connected to the battery assembly by measuring whether the capacitor is discharged
