Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a large bulky gas container is used to deliver coolant airflow, then the cooling effect is achieved, but the device becomes heavy and difficult to transport
Solution Approach 1:
The device separates the gas container and coolant reservoir into distinct, modular components. The gas container holds pressurized gas while the coolant reservoir contains the cooling liquid, allowing independent optimization of each component's weight and function. This segmentation enables the device to achieve effective cooling without requiring a single bulky integrated system.
Solution Approach 2:
The patent introduces a spray nozzle as an intermediary component that mixes pressurized gas with coolant liquid to create a cooled airflow. This intermediary mechanism allows the system to achieve effective cooling through a lightweight mixing process rather than requiring heavy pressurized coolant storage or complex compression systems.
2Measurement precision
If separate flow and pressure transducers are used, then airflow and coolant injection are precisely controlled, but device complexity increases
Solution Approach 1:
The flow transducer and pressure transducer are integrated into a single combined transducer assembly that simultaneously measures both airflow rate and pressure. This merging of measurement functions into one component reduces the total number of separate parts, simplifies the control system architecture, and maintains high measurement precision for both parameters without increasing overall device complexity.
Solution Approach 2:
The transducer system is designed with multi-functional capability, where the same transducer assembly performs multiple measurement functions (flow and pressure sensing) and provides control feedback for both airflow regulation and coolant injection timing. This universal design reduces component count while maintaining precise control over multiple parameters.
