Smart Window Prompt Device for Indoor Air Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often forget to open or close windows reasonably, leading to poor indoor air quality, which affects health and can result in indoor air pollution or security issues.
Innovation Solution
A method and device that acquire information about the open-or-closed state of doors or windows and indoor/outdoor environments to generate prompts for optimal opening/closing, considering factors like air quality, device operation, and harmful gas content, and can control the windows automatically or via mobile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user opens or closes doors and windows manually, then the user has control over indoor air circulation, but the user often forgets to open or close the window, leading to poor indoor air quality
Solution Approach 1:
The system automatically monitors indoor and outdoor air quality parameters (PM2.5, temperature, humidity, etc.) and autonomously determines whether to open or close windows/doors based on the comparison results, eliminating the need for manual user operation while ensuring reliable air quality maintenance
Solution Approach 2:
The system continuously monitors air quality parameters and provides real-time feedback through prompts to users about the optimal window/door state, creating a closed-loop control system that adjusts behavior based on environmental conditions
2Productivity
If the user opens windows when outdoor air quality is poor, then indoor air circulation is improved, but indoor air pollution increases due to outdoor pollutants entering
Solution Approach 1:
The system performs preliminary monitoring and comparison of indoor and outdoor air quality parameters before making the decision to open or close windows, predicting the outcome of potential actions and selecting the optimal one in advance to avoid introducing pollutants
Solution Approach 2:
The system autonomously compares air quality data and determines the optimal window state without user intervention, automatically preventing pollution entry by closing windows when outdoor quality is poor while maintaining circulation when outdoor quality is good
3Reliability
If the system provides automated window control based on air quality monitoring, then indoor air quality is maintained, but the system complexity increases
Solution Approach 1:
The system integrates multiple air quality monitoring functions (PM2.5, temperature, humidity, formaldehyde detection) and window control functions into a single multi-functional platform, reducing overall system complexity through consolidation while maintaining comprehensive air quality management capabilities
Solution Approach 2:
The system introduces a mobile terminal as an intermediary communication interface between the air quality monitoring device and the user, simplifying the direct system complexity by offloading the interaction layer to a separate, standardized communication channel
