Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button switch is used to control power supply to the atomization element, then the atomizer can be operated manually, but it requires two hands and is inconvenient for patients
Solution Approach 1:
The atomizer automatically detects user inhalation through the airflow sensor and activates atomization without requiring manual button operation. The system serves itself by using the inhalation action itself as the trigger signal, eliminating the need for separate control operations by patients
Solution Approach 2:
The mechanical button switching system is replaced with an automated sensing system using an airflow sensor that detects inhalation patterns. This substitution transforms manual mechanical control into automated sensor-based control, improving accessibility for patients
2Loss of energy
If the atomizer is operated only when needed, then energy is saved, but manual operation requires both hands and is time-consuming
Solution Approach 1:
The airflow sensor provides real-time feedback about user inhalation to the control system. This feedback mechanism enables the atomizer to automatically activate when inhalation is detected and deactivate when inhalation stops, optimizing both energy consumption and response time without requiring manual intervention
Solution Approach 2:
The system is prepared in advance with the airflow sensor continuously monitoring for inhalation patterns. When inhalation is detected, atomization immediately activates without requiring the user to first manually turn on the device, reducing operation time while maintaining energy efficiency
3Device complexity
If the battery only comprises a cell, then the design is simple, but it cannot intelligently control power supply to the atomizer
Solution Approach 1:
The battery design merges the cell with integrated control electronics including the airflow sensor and control circuitry into a single unified unit. This combination enables intelligent power control that automatically responds to inhalation detection while maintaining a compact, integrated structure rather than separate components
Solution Approach 2:
The integrated battery unit serves multiple functions: it provides power storage through the cell, detects inhalation through the airflow sensor, controls power supply timing, and manages overall battery operation. This multi-functionality enables intelligent control without significantly increasing structural complexity

AI summary
An integrated battery using an airflow sensor for control comprises an outer casing, a cell and a PCBA. The cell and the PCBA are both arranged in the outer casing, and the PCBA is electrically connected with the cell. The PCBA is provided with a positive plate, a negative plate and an airflow sensor. The outer casing is provided with an air inlet. The airflow sensor is arranged on the battery to control discharge of the cell, such that the battery can be used together with some atomizers to realize instant atomization when users inhale, and the waste of atomizing liquid is avoided.
