Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If outside air processing and air-conditioning devices operate independently with separate control, then each device can be controlled individually, but humidity control efficiency deteriorates and energy consumption increases
Solution Approach 1:
The patent combines the outside air processing device and air-conditioning device into an integrated system with unified control. The control unit coordinates both devices to work together, adjusting outside air intake and air-conditioning operations simultaneously to achieve humidity control goals, thereby reducing total energy consumption compared to independent operation.
Solution Approach 2:
The integrated control system performs multiple functions including outside air processing, air-conditioning, and humidity control through a single coordinated operation. The control unit manages both heating/cooling and humidity regulation functions, making the system more versatile and efficient than separate devices.
2Temperature
If outside air processing device performs supply air temperature control to make temperature close to set value, then temperature control is achieved, but humidity control capability deteriorates
Solution Approach 1:
The control unit dynamically adjusts operating parameters based on real-time humidity sensor feedback. When humidity control is needed, the system modifies supply air temperature and airflow rate dynamically, rather than maintaining a fixed temperature setpoint, enabling the system to adapt to varying humidity requirements.
Solution Approach 2:
The patent changes the control parameter from solely temperature-based control to humidity-based control with adjustable temperature and airflow rate. The control unit modifies supply air temperature and airflow rate as control parameters to achieve target humidity levels, expanding the system's adaptability beyond temperature control alone.
3Adaptability or versatility
If airflow rate is increased to improve ventilation and humidity control, then humidity control improves, but energy consumption increases
Solution Approach 1:
The system incorporates humidity sensors that provide feedback to the control unit. The control unit continuously monitors indoor humidity levels and adjusts airflow rate and supply air temperature based on this feedback, increasing airflow only when necessary to achieve target humidity levels rather than maintaining constant high airflow, thereby reducing energy consumption.
Solution Approach 2:
The control unit applies partial action by adjusting airflow rate and supply air temperature only to the extent necessary to achieve target humidity levels. Rather than maintaining excessive airflow or temperature differences, the system uses the minimum required action to meet humidity control goals, reducing energy waste.
