Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If natural ventilation is used, then energy consumption is reduced, but ventilation uniformity and controllability deteriorate
Solution Approach 1:
The ventilation system is divided into multiple independent air supply outlets, each equipped with individual valves and control mechanisms. This segmentation allows precise control of air flow to different zones, achieving uniform ventilation distribution while maintaining energy efficiency through targeted air supply only where animals are present.
Solution Approach 2:
The system dynamically adjusts ventilation parameters based on real-time detection of animal presence and environmental conditions. The controller automatically modifies air supply rates, outlet orientations, and valve openings according to changing conditions, ensuring optimal ventilation uniformity and controllability while minimizing energy consumption.
2Temperature
If tunnel ventilation with wet pad cooling is used, then cooling effect is improved, but precise individual animal cooling capability deteriorates
Solution Approach 1:
The system provides customized cooling to each local area based on detected animal presence and posture. Different air supply rates, temperatures, and orientations are applied to different zones, enabling precise individual animal cooling while maintaining overall effective cooling across the facility.
Solution Approach 2:
The system continuously detects animal presence, posture, and environmental conditions, then feeds this information back to the controller which adjusts air supply parameters in real-time. This closed-loop control enables precise individual animal cooling by adapting to each animal's specific needs while maintaining overall cooling effectiveness.
3Temperature
If air ducting system is used, then cool air supply to animal zone is improved, but adaptability to bulk air movement and precise ventilation regulation deteriorates
Solution Approach 1:
The air ducting system incorporates dynamically adjustable components including variable opening valves, movable outlets, and rotating mechanisms that adapt to changing air flow conditions and animal positions. This enables the system to maintain effective cool air supply while adapting to bulk air movement patterns and providing precise ventilation regulation.
Solution Approach 2:
Real-time detection of air flow conditions and animal presence feeds back to the controller, which automatically adjusts ducting parameters including valve openings, outlet orientations, and air supply rates. This feedback mechanism enables the system to adapt to varying air movement patterns while maintaining precise ventilation control and effective cool air delivery.
4Device complexity
If manual ventilation control is used, then system complexity is reduced, but ventilation precision and automatic regulation capability deteriorate
Solution Approach 1:
The system automatically detects animal presence, monitors environmental conditions, and adjusts ventilation parameters without human intervention. The controller self-regulates valve openings, outlet orientations, and air supply rates based on sensor feedback, achieving high ventilation precision while keeping operational complexity manageable through automation.
Solution Approach 2:
Manual mechanical control is replaced with automated detection and control systems including cameras, sensors, and electronic actuators. This substitution enables precise ventilation regulation and automatic adaptation to changing conditions while managing system complexity through integrated control algorithms and automated decision-making.
