Electronic Inhaler Menu Control Using a Pressure Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic inhalation devices lack user customization and safety features, as they typically operate in a single mode without the ability to modify settings or prevent unintended vaporizer activation.
Innovation Solution
Incorporating a microprocessor with a menu mode that allows users to configure settings via a pressure sensor, enabling selection of options to alter operational parameters, disable vaporizer activation, and reset device settings, while using sound signals for navigation and notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a menu mode is added to allow user configuration, then user customization capability is improved, but device complexity increases
Solution Approach 1:
The existing pressure sensor, originally designed solely to detect inhalation for vaporizer activation, is enhanced to serve dual purposes: it continues to detect normal inhalation events while also functioning as an input device for menu mode navigation. By detecting specific inhalation patterns (such as prolonged inhalation or multiple sequential inhalations), the sensor enables users to enter menu mode, navigate options, and configure device settings without requiring additional buttons or input mechanisms. This multi-functionality approach allows the device to gain user customization capability while avoiding the complexity increase that would result from adding separate input hardware.
2Device complexity
If the pressure sensor is used as an input device for menu mode, then the number of components is reduced, but the reliability of normal vaporizer activation may be affected
Solution Approach 1:
Different functional responses are assigned to different characteristics of the same input signal from the pressure sensor. Normal inhalation patterns (typical duration and intensity) trigger vaporizer activation, while specific distinct patterns (such as prolonged inhalation exceeding a threshold duration, or multiple rapid sequential inhalations) trigger menu mode entry. The controller analyzes the temporal and intensity characteristics of each pressure sensor signal to determine the user's intent, ensuring that normal vaporizer operation remains reliable while enabling menu access through deliberately different inhalation behaviors.
Solution Approach 2:
The system dynamically adjusts its interpretation of pressure sensor signals based on the current operational state. When in normal operation mode, the pressure sensor triggers vaporizer activation. When specific patterns are detected, the system transitions to menu mode where subsequent pressure sensor inputs are interpreted as menu navigation commands rather than vaporizer activation requests. This dynamic state-dependent interpretation ensures reliable distinction between normal use and menu interaction.
3Reliability
If menu mode is activated during normal operation, then user safety is improved by preventing unintended vaporizer activation, but the ease of operation decreases
Solution Approach 1:
The system performs preliminary analysis of the inhalation pattern before transitioning to menu mode. By detecting specific predefined patterns (such as prolonged inhalation or multiple sequential inhalations) that are distinct from normal usage, the system proactively enters menu mode before any unintended vaporizer activation can occur. This preliminary detection and state transition prevents the safety issue from arising in the first place, while the distinct pattern requirements ensure that accidental menu entry remains unlikely.
