Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air conditioner runs continuously to ensure environmental parameters, then temperature stability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic air volume regulation by adjusting the opening degree of air valves based on real-time temperature differences between cabinet outlets and preset values. The system transitions from static continuous operation to dynamic adaptive operation, where air volume is continuously adjusted according to actual thermal conditions and workload variations.
Solution Approach 2:
The system changes the operating parameters of the air conditioning system by regulating air volume through variable air volume terminal devices. By modifying the air flow parameter dynamically based on temperature feedback, the system achieves both temperature stability and energy efficiency.
2Loss of energy
If air volume is regulated according to actual workload, then energy saving is improved, but control complexity increases
Solution Approach 1:
The patent employs a feedback control mechanism where temperature sensors monitor the actual temperature at cabinet outlets, compare it with preset temperature values, and use the temperature difference to adjust the opening degree of air valves. This closed-loop feedback system enables automatic adaptive regulation without requiring complex manual control.
Solution Approach 2:
The air conditioning system performs self-regulation by automatically adjusting its own air volume based on internal temperature conditions. The system monitors its own performance and makes autonomous adjustments to maintain optimal operation, reducing the need for external complex control systems.
3Ease of manufacture
If focus on air flow distribution designs and layouts, then initial setup is improved, but adaptability to workload changes worsens
Solution Approach 1:
The patent introduces dynamic adjustability to the air flow distribution system through variable air volume terminal devices with controllable air valves. This transforms the previously static air flow distribution design into a dynamic system that can adapt to varying workloads while maintaining the benefits of optimized air flow paths.
