Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple ventilation devices operate independently without coordinated control, then each device can function autonomously, but the filters and fans experience uneven wear leading to increased maintenance costs and potential ventilation impairment
Solution Approach 1:
The patent merges the control of multiple ventilation devices into a single coordinated control system that manages filters and fans across all devices. By combining individual device operations under unified control, the system synchronizes maintenance timing, ensures balanced workload distribution, and prevents uneven wear, thereby improving overall reliability while optimizing maintenance scheduling.
2Ease of manufacture
If maintenance is performed on each ventilation device independently, then maintenance can be done whenever needed, but it leads to increased maintenance costs and potential ventilation impairment due to unsynchronized operations
Solution Approach 1:
The control device performs preliminary actions by predicting the lifespan of filters and fans using machine learning models before actual failure occurs. It proactively schedules maintenance at optimal times when multiple components reach their maintenance thresholds simultaneously, preventing unexpected failures and ensuring continuous ventilation performance while reducing overall maintenance costs through planned interventions.
3Loss of time
If the control system synchronizes maintenance of all filters and fans, then maintenance costs are reduced and ventilation impairment is minimized, but the system complexity increases
Solution Approach 1:
The control system implements feedback mechanisms by continuously monitoring the operational status, environmental conditions, and predicted lifespan of filters and fans across multiple ventilation devices. This feedback loop enables the system to dynamically adjust maintenance scheduling, synchronize replacement timing, and optimize resource allocation, achieving cost reduction and performance maintenance while managing complexity through intelligent automation.
4Measurement precision
If environmental conditions are not considered in maintenance scheduling, then maintenance can be performed on a fixed schedule, but it leads to inaccurate lifespan predictions and suboptimal maintenance timing
Solution Approach 1:
The system applies parameter changes by incorporating environmental conditions (temperature, humidity, air quality) as dynamic variables in the machine learning models that predict filter and fan lifespan. These parameter changes enable more accurate predictions of component degradation rates, allowing the control device to adjust maintenance timing based on actual operating conditions rather than fixed schedules, thereby improving prediction accuracy while managing data processing complexity through efficient algorithms.

AI summary
A control device includes an acquisition unit and a control unit. The acquisition unit acquires first information indicating information on an operating time of a first device and an environmental condition that influences a life of a first instrument provided for the first device, and information on an operating time of a second device and an environmental condition that influences a life of a second instrument provided for the second device. The control unit operates the first device and the second device in conjunction with each other based on the first information acquired by the acquisition unit.
