Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurately measuring the remaining power in the power source of aerosol delivery devices, such as e-cigarettes, is challenging due to the presence of additional electrical components that modulate power, making direct connection to a power measurement device unreliable.
Innovation Solution
A system comprising a test fixture, a vacuum source, and a power measurement device that couples to the power unit, using a power storage device to accurately measure the power stored in the power unit by inducing a vacuum and measuring the electrical charge, which remains constant despite power modulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct connection to power measurement device is used, then measurement simplicity is improved, but measurement precision deteriorates due to power modulation by additional electrical components
Solution Approach 1:
The patent introduces a power storage device as an intermediary component between the power source and the power measurement device. This mediator stores electrical energy from the power source and allows accurate measurement of the stored energy, bypassing the power modulation issues caused by additional electrical components in the power unit.
2Device complexity
If power measurement is performed through power unit components, then device complexity is reduced, but reliability of measurement deteriorates
Solution Approach 1:
The power storage device serves as a reliable intermediary that decouples the measurement process from the power modulation components. By measuring the energy stored in this dedicated storage device rather than attempting to measure through the modulating components, the system achieves reliable measurements without requiring complex measurement circuits within the power unit.
3Ease of operation
If vacuum induction is used to activate power unit, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent employs a vacuum source to create negative pressure that activates the power unit and drives aerosol precursor material through the system. This pneumatic approach simplifies activation compared to electrical switching mechanisms, though it does add a vacuum source component to the testing system.
