Aerosol Battery Capacity Buffer for Consistent Smoking Cycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating apparatuses experience degradation in battery capacity over time, leading to a diminished user experience due to the need for more frequent charging, which is not effectively addressed by existing technologies.
Innovation Solution
The apparatus is designed to limit the number of smoking cycles on a single charge to a defined usable capacity below the initial capacity, preventing further degradation from being perceived by the user, and ensuring consistent performance throughout the device's lifetime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the full initial battery capacity is utilized, then the number of smoking cycles per charge increases, but the user experiences battery degradation over time requiring frequent recharging
Solution Approach 1:
The patent applies partial action by deliberately limiting the usable battery capacity to a subset of the total capacity. The controller is configured to prevent the battery from being fully discharged, maintaining a residual capacity threshold (e.g., 20% of initial capacity) that is never depleted. This partial utilization strategy ensures consistent performance across the device lifetime by preventing the battery from operating in its degraded low-capacity state, thereby resolving the contradiction between maximizing smoking cycles and maintaining reliability.
2Reliability
If the battery capacity is reduced to a usable level below initial capacity, then consistent performance is maintained, but the total energy available per charge is reduced
Solution Approach 1:
The patent implements parameter changes by dynamically adjusting the effective battery capacity parameter based on the battery's age and degradation state. The controller monitors battery health and adapts the usable capacity threshold accordingly, changing the operational parameters to maintain consistent performance. This allows the system to optimize between reliability and energy utilization by modifying the capacity parameter in response to battery condition, rather than using a fixed capacity limit throughout the battery lifecycle.

AI summary
The present disclosure relates to an aerosol generating apparatus. A drawback with known aerosol generating apparatuses is that the power supply, over time, may degrade and loose some of its capacity, resulting in diminished user experience required a more frequent charging of the aerosol generating apparatus. Accordingly, there is provided an aerosol generating apparatus (1), comprising a battery (2) having an undegraded, initial battery capacity, wherein, when the battery (2) is fully charged, the initial battery capacity provides sufficient energy to power the aerosol generating apparatus (1) for x smoking cycles on a single charge, wherein x in a natural number, wherein a smoking cycle corresponds to the consumption of a single consumable (70) by a user, wherein a smoking cycle requires a defined amount of energy, wherein the aerosol generating apparatus (1) is arranged to provide a usable battery capacity providing sufficient energy to power the aerosol generating apparatus (1) for no more than y smoking cycles, wherein y is natural number less than x such that the usable battery capacity is lower than the initial battery capacity, and wherein after y single smoking cycles, the aerosol generating apparatus (1) is arranged to any one of or more of: (i) require a recharge, (ii) prevent the initiation of a further smoking cycle, and (iii) indicate a depleted battery capacity.
