Portable Device Exhalation Sensor Projection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices that measure exhalation components, such as alcohol or bad breath, require separate breathmeters or manual blowing into the device, making them inconvenient and unable to automatically detect exhalation without user awareness.
Innovation Solution
A portable device with an integrated gas detector that automatically projects from the device body during a call, inclining towards the user's mouth to sense exhalation, featuring a sliding actuator, rotatable gas sensor, and rechargeable battery with wireless charging, capable of detecting various compounds like alcohol, carbon monoxide, and VOCs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate breathmeter is used with the portable device, then the exhalation measurement function is added, but the convenience of carrying both devices is reduced
Solution Approach 1:
The patent integrates the breathmeter function into the portable device by incorporating a gas sensor module that can detect exhalation components (alcohol, bad breath, etc.) directly within the device body, eliminating the need for a separate breathmeter and improving portability while maintaining measurement functionality
2Measurement precision
If the user manually blows breath into the device, then the measurement can be performed, but the automatic detection capability is lost
Solution Approach 1:
The patent employs a movable gas sensor module that can dynamically adjust its position and orientation relative to the user's mouth during calls. The sensor module can be projected outward or rotated to different angles to optimally detect exhalation, enabling automatic detection without requiring the user to manually position their breath
Solution Approach 2:
The device automatically detects and measures exhalation components during calls without requiring explicit user action. The gas sensor module autonomously monitors the user's breath, and the system automatically processes the measurement data, eliminating the need for manual operation while maintaining accurate detection
3Device complexity
If the gas detector is integrated into the device body, then the device structure is simplified, but the ability to automatically sense exhalation during calls is reduced
Solution Approach 1:
The gas sensor module is designed as a movable component that can be projected outward from the device body or rotated to different angles. This dynamic capability allows the sensor to automatically sense exhalation during calls while maintaining a compact integrated structure when not in use, resolving the contradiction between structural simplicity and automatic sensing functionality
