Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vaporization devices often experience false start-ups when placed in charging boxes due to compressed gas triggering the airflow sensor, leading to inefficient operation and user inconvenience.
Innovation Solution
An aerosol-generation system with a charging box that includes an air discharging channel to release cavity air externally, preventing air from entering the sensor and triggering false activations, and a holder design that accommodates the vaporization device with airflow detection ports and conductive contacts for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vaporization device is placed in the charging box, then the device is charged and stored, but the compressed gas in the cavity triggers the airflow sensor causing false start-up
Solution Approach 1:
The charging box is divided into separate functional regions: a storage cavity for holding the vaporization device and an air discharge channel for gas venting. This segmentation allows the charging box to independently manage storage and air pressure control functions, preventing false sensor activation while maintaining a relatively simple overall structure.
Solution Approach 2:
An air discharge channel is introduced as an intermediary component between the storage cavity and the external environment. This channel acts as a mediator that releases compressed gas from the cavity without allowing it to reach the airflow sensor, thus preventing false start-up events while keeping the charging box structure straightforward.
2Ease of operation
If the airflow sensor is used to detect inhalation, then the vaporization device activates on demand, but compressed gas in the charging box cavity causes false activation
Solution Approach 1:
The air discharge channel extracts and removes compressed gas from the charging box cavity before it can reach the airflow sensor. By taking out the problematic gas accumulation from the sensor's detection path, the airflow sensor can accurately distinguish between genuine inhalation signals and false signals caused by cavity pressure changes.
Solution Approach 2:
The air discharge channel converts the potentially harmful effect of compressed gas (which could cause false activation) into a beneficial pressure equalization mechanism. The channel allows controlled gas release that maintains proper atmospheric pressure in the cavity, ensuring the airflow sensor operates in a stable pressure environment and accurately detects only intentional inhalation.
