Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices lack effective mechanisms to prevent overheating and battery depletion based on ambient temperature conditions, leading to reduced user experience and potential device failure.
Innovation Solution
An aerosol provision device that determines ambient temperature, compares it to a threshold value, and sets limits on the number of back-to-back usage sessions to mitigate overheating and battery depletion by adjusting usage based on temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the device allows continuous back-to-back usage sessions without temperature-based limits, then user convenience and productivity are improved, but device overheating and battery depletion occur reducing reliability
Solution Approach 1:
The system performs preliminary temperature assessment before allowing usage sessions. By determining ambient temperature in advance and comparing it to threshold values, the system proactively sets appropriate limits on back-to-back sessions, preventing overheating and battery depletion before they occur.
Solution Approach 2:
The limit on back-to-back usage sessions is made dynamic rather than fixed. The system adjusts the number of allowed sessions based on the determined ambient temperature, increasing limits when temperature is below thresholds and decreasing limits when temperature exceeds thresholds, optimizing both productivity and reliability across varying conditions.
2Adaptability or versatility
If the device operates without ambient temperature monitoring, then device complexity is reduced, but the ability to adapt to varying temperature conditions is lost
Solution Approach 1:
The temperature sensor serves multiple functions: it determines ambient temperature for adaptive session limiting and simultaneously monitors battery temperature for safety. This multi-functionality increases adaptability while minimizing the addition of separate dedicated components.
Solution Approach 2:
The system uses its own internal temperature sensor to monitor ambient conditions and automatically adjust its operational parameters. The device self-regulates by comparing its determined temperature against stored threshold values and autonomously setting appropriate usage limits without external intervention.
