Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ventilation systems integrate complex sensing capabilities directly into the system, then measurement precision and control accuracy are improved, but device complexity and installation cost increase
Solution Approach 1:
The system separates sensing functions from the ventilation system itself by using external sensor systems that connect to a controller via communication interfaces. This segmentation allows the ventilation system to maintain simple structure while still achieving precise measurement through dedicated sensor components.
Solution Approach 2:
A communication interface acts as an intermediary between external sensor systems and the controller, enabling data transmission without requiring direct integration of sensing capabilities into the ventilation system. This mediator approach reduces device complexity while maintaining measurement precision.
2Extent of automation
If ventilation systems are equipped with integrated sensing and control capabilities, then automation level is improved, but ease of manufacture and retrofitting difficulty worsen
Solution Approach 1:
The control system is segmented into independent components: external sensor systems, communication interfaces, and a controller that interfaces with the existing ventilation system. This modular approach enables automatic control while keeping manufacturing and installation costs low, as each component can be produced and installed separately.
Solution Approach 2:
The controller is designed with universal communication interfaces that can work with various types of sensor systems and ventilation systems. This multi-functionality allows the same controller to achieve automation across different applications without requiring custom-designed integrated systems, thereby reducing manufacturing costs and facilitating retrofitting.
3Adaptability or versatility
If conventional ventilation systems are upgraded with sensing capabilities through retrofitting, then adaptability is improved, but device complexity and installation complexity increase
Solution Approach 1:
The controller incorporates universal communication interfaces that can communicate with various sensor systems and interface with different types of ventilation systems (HRV, ERV, etc.). This universality provides high adaptability while maintaining relatively simple device complexity, as the same controller hardware can be used across multiple applications.
Solution Approach 2:
The communication interface serves as an intermediary layer between existing ventilation systems and new sensor systems, enabling retrofitting without requiring complex integration work. This mediator approach allows conventional systems to gain sensing capabilities while minimizing the increase in device complexity.
