Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fan is used to provide wind flow, then the heat dissipation function is achieved, but the ability to simulate changing wind directions is limited
Solution Approach 1:
The simulator is divided into multiple independent nozzle units (at least three nozzles arranged in different directions), each capable of independently controlling airflow direction and volume. This segmentation allows the system to simulate wind from various directions by selectively activating and adjusting individual nozzles, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
Each nozzle is equipped with independent flow rate regulators that can dynamically adjust airflow volume in real-time. The regulators enable continuous variation of wind strength and direction, allowing the system to adapt to different virtual environment requirements while maintaining a relatively simple overall structure.
2Adaptability or versatility
If multiple nozzles and regulators are added to control airflow direction and volume, then wind field simulation capability is improved, but the device complexity increases
Solution Approach 1:
The regulator assembly serves multiple functions: it controls flow rate, directs airflow, and can be integrated with thermoregulators and humidity controllers. This multi-functionality reduces the need for separate components for each function, thereby improving wind field control precision while limiting the increase in overall device complexity.
Solution Approach 2:
Multiple control functions (flow rate regulation, temperature control, humidity control) are merged into integrated assemblies positioned at or near the nozzles. This consolidation allows precise wind field simulation through coordinated control of multiple parameters simultaneously, while reducing the total number of separate components and simplifying the overall structure.
3Adaptability or versatility
If thermoregulators, humidity controllers, and odor controllers are integrated, then multi-sensory simulation capability is improved, but the device complexity increases
Solution Approach 1:
Thermoregulators, humidity controllers, and odor controllers are integrated into unified assemblies that work in coordination with the airflow system. This merging allows simultaneous control of multiple sensory parameters (wind, temperature, humidity, odor) through a coordinated system, improving multi-sensory simulation capability while managing device complexity through integrated design.
Solution Approach 2:
The control system is designed with multi-functional components that can simultaneously manage multiple environmental parameters. Each controller assembly serves multiple functions (e.g., a single assembly may regulate both temperature and humidity), enabling comprehensive multi-sensory simulation without proportionally increasing the number of separate control systems.
