Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional testing methods are used to test atomization devices, then individual devices can be tested, but the testing efficiency is low and aerosol pollution occurs
Solution Approach 1:
The patent combines multiple testing functions into a single integrated system. Multiple atomization devices are connected to a common main tube through connecting pipes, allowing simultaneous testing of multiple devices. The air suction mechanism, liquid supply mechanism, and aerosol condensation module are merged into one coordinated system that efficiently tests multiple devices while controlling pollution.
Solution Approach 2:
The aerosol condensation module condenses the aerosol generated during testing, recovering the liquid form and preventing direct release into the environment. This addresses the pollution issue by transforming the harmful aerosol state back into a manageable liquid state for proper disposal or reuse.
2Productivity
If multiple atomization devices are tested simultaneously, then testing efficiency improves, but the system complexity increases
Solution Approach 1:
The system is segmented into distinct functional modules: a main tube for common airflow, individual connecting pipes for each device, separate air suction mechanism, liquid supply mechanism, and aerosol condensation module. This modular segmentation allows simultaneous testing of multiple devices while maintaining manageable system complexity through clear functional separation.
Solution Approach 2:
The main tube serves as a universal component that handles airflow for multiple devices simultaneously. The air suction mechanism, liquid supply mechanism, and aerosol condensation module are universal systems that serve all connected atomization devices, reducing the need for duplicate components for each device.
3Ease of operation
If automated liquid replenishment is implemented, then testing convenience improves, but the device complexity increases
Solution Approach 1:
The liquid supply mechanism is designed to automatically replenish medicinal liquid to the atomization devices during testing without requiring manual intervention. The system self-regulates the liquid supply process, improving operational convenience while the automation is integrated into the overall system design rather than adding separate complex subsystems.
