Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional mixing ventilation method is used to regulate and control the entire room, then the system has strong versatility, but the adaptability to different use functions and requirements is poor
Solution Approach 1:
The ventilation system is divided into multiple independent ventilation modules, each capable of independent control. Each module includes supply air outlets and return air outlets that can be independently adjusted, allowing different zones within the room to have customized ventilation configurations suited to specific use functions and requirements.
Solution Approach 2:
The system employs adjustable air outlet devices that can dynamically change their air supply and return directions. The air outlets can be rotated or repositioned to adapt to different usage scenarios, transforming a static ventilation system into a dynamic one that responds to changing functional requirements.
2Adaptability or versatility
If traditional mixing ventilation method is used, then the system structure is simple, but it cannot create the most suitable indoor environment for different scenarios
Solution Approach 1:
Each ventilation module is designed as a universal unit that can serve multiple functions and adapt to different scenarios. The modules can be configured for various uses such as meeting modes, office modes, or classroom modes by adjusting the air outlet directions, making a single module type capable of handling diverse ventilation requirements without requiring specialized equipment for each scenario.
Solution Approach 2:
The ventilation system uses a modular design where standardized ventilation modules can be nested or combined in different configurations to suit different room sizes and functions. Multiple modules work together as a coordinated system, with each module containing integrated components (supply outlets, return outlets, control mechanisms) that function as a complete unit.
3Adaptability or versatility
If traditional ventilation system with fixed air outlets is used, then the system is easy to operate, but it cannot adapt to different personnel distributions and indoor functions
Solution Approach 1:
The air outlets are designed to be adjustable rather than fixed, allowing operators to reposition supply and return air outlets to match different personnel distributions and indoor functions. This dynamic adjustment capability enables the system to adapt to various scenarios while maintaining operational simplicity through intuitive control mechanisms.
4Object-affected harmful factors
If mixing ventilation method is used throughout the room, then the system has high versatility, but it increases the probability of cross-infection among people in the entire room
Solution Approach 1:
The ventilation system divides the room into multiple independently controllable zones using separate ventilation modules. Each module can be configured to create localized ventilation patterns that prevent pollutant diffusion across the entire room, thereby reducing cross-infection risk while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The system implements localized ventilation control where each ventilation module can be independently adjusted to create optimal air flow patterns for specific local areas. This allows different parts of the room to have customized ventilation characteristics suited to their specific functions and occupancy patterns, reducing the spread of contaminants while maintaining operational simplicity.
