Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ventilation systems use simple air outlets with adjustable lamellas, then the device complexity is low, but the airflow direction control precision and ventilation comfort are insufficient
Solution Approach 1:
The patent replaces conventional mechanical lamella adjustment systems with an electric field-based deflection device. Ionized air particles are deflected using electric fields generated by electrodes, eliminating the need for complex mechanical directional adjustment mechanisms while achieving precise airflow control.
Solution Approach 2:
The system changes the physical state of air by ionizing it before deflection. This parameter change (from neutral to ionized state) enables the air to respond to electric fields, providing new control dimensions for airflow direction without mechanical components.
2Adaptability or versatility
If ionization device is added to ionize the air, then the airflow can be deflected by electric fields, but the device complexity and energy consumption increase
Solution Approach 1:
The patent combines the ionization device and deflection device into an integrated system where the same electric field infrastructure serves dual purposes. The ionization electrodes and deflection electrodes work in conjunction, sharing power supply and control circuits, thereby reducing overall system complexity despite adding functionality.
Solution Approach 2:
The electric field generation system serves multiple functions: ionizing the air and subsequently deflecting the ionized air particles. This multi-functionality reduces the need for separate dedicated components for each function, optimizing the device complexity-benefit ratio.
3Measurement precision
If deflection device generates strong electric and/or magnetic fields to deflect ionized air, then the airflow direction precision is improved, but the energy consumption increases
Solution Approach 1:
The deflection device uses dynamically adjustable electric fields rather than static strong fields. The field intensity and direction can be varied in real-time to match the required airflow direction, consuming energy only when and where needed, thus reducing overall energy consumption while maintaining precision.
Solution Approach 2:
The system changes the state of air particles through ionization, which enables them to respond to relatively weaker electric fields compared to what would be needed for mechanical deflection. This parameter change (neutral to ionized) allows precise control with lower energy input.
