Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Buildings often lack mechanisms to measure and improve air quality, which can impact the health of occupants, and existing solutions do not effectively address the need for dynamic air quality management and infectious disease risk reduction.
Innovation Solution
A building system that connects to temporary air quality sensors to collect data, generates control strategies based on measurements, and implements these strategies to improve indoor air quality and reduce infectious disease spread by integrating with building management systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temporary air quality sensors are deployed throughout building spaces, then air quality measurement coverage is improved, but system complexity and installation burden increase
Solution Approach 1:
The patent employs temporary air quality sensors that are deployed for specific measurement periods and then removed, rather than permanent installations. These sensors are designed to be cost-effective and easily deployable for short-term use, allowing comprehensive air quality assessment without the complexity and cost of permanent sensor networks throughout the building.
2Reliability
If air quality data is collected over extended periods, then data accuracy and reliability improve, but loss of time and resource consumption increase
Solution Approach 1:
The system performs preliminary air quality assessments by deploying sensors for specific periods to gather baseline data and identify problem areas. Based on these preliminary results, targeted follow-up measurements are conducted only in spaces showing concerning air quality metrics, rather than continuously monitoring all spaces indefinitely. This approach maintains data reliability while minimizing time loss.
3Object-affected harmful factors
If control strategies are generated and implemented based on air quality measurements, then air quality improvement is achieved, but device complexity and operational burden increase
Solution Approach 1:
The system generates control strategies that leverage existing building management infrastructure and automated control capabilities. Rather than requiring complex new control systems, the solution uses the building's existing HVAC and ventilation systems to implement air quality improvements based on sensor data, reducing operational burden while achieving health benefits.
4Object-affected harmful factors
If comprehensive air quality monitoring is implemented, then infectious disease risk detection improves, but cost of substance and resource consumption increase
Solution Approach 1:
The system focuses air quality monitoring and intervention resources on specific local areas within the building where air quality problems or infectious disease risks are detected, rather than uniformly monitoring and treating all spaces. Sensors are strategically placed in high-occupancy areas, ventilation zones, and spaces showing elevated risk metrics, optimizing resource consumption while maintaining effective disease risk detection.

AI summary
A building system can connect to temporary air quality sensors installed throughout spaces of the building for a period of time. The building system can receive air quality measurements of the temporary air quality sensors over the period of time and disconnect from the temporary air quality sensors at an end of the period of time, wherein the temporary air quality sensors are uninstalled at the end of the period of time. The building system can generate a control strategy based on the air quality measurements, the control strategy for controlling equipment of the building to improve air quality of the building and cause a building management system to implement the control strategy to control the equipment of the building to improve the air quality of the building.
