Home air purification system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home air purification systems require users to place appliances in each room individually, leading to inefficiency and unnecessary effort, as they do not provide real-time air quality information across the dwelling.
Innovation Solution
An air purification system with a control unit, filtration unit, and a nomadic air sensor that can be coupled or uncoupled from the air purifier, allowing for autonomous measurement and communication of air quality data to a human-machine interface, enabling the air purifier to operate in either coupled or uncoupled modes based on sensor feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the user places the air purifier in each room individually to treat them one by one, then each room can be treated, but it results in waste of time and unnecessary effort, and the user cannot inform about air quality throughout the dwelling
Solution Approach 1:
The system separates the air purifier from the air sensor, allowing the sensor to be moved independently to different rooms while the purifier remains stationary. This segmentation enables the sensor to collect air quality data from multiple locations without requiring the user to move the entire purifier unit, thus reducing user effort while providing comprehensive air quality information.
Solution Approach 2:
The nomadic air sensor acts as an intermediary between the air purifier and the environment. It can be placed in different rooms to measure air quality and communicate this information to the purifier, enabling the system to gather information throughout the dwelling without physically relocating the main purifier unit.
2Reliability
If the air purifier operates in coupled mode with the nomadic air sensor, then closed-loop control is achieved, but the system complexity increases
Solution Approach 1:
The system dynamically switches between coupled and uncoupled operating modes based on the connection status of the nomadic air sensor. When the sensor is connected, the system operates in coupled mode with closed-loop control for optimal performance. When disconnected, it automatically transitions to uncoupled mode, maintaining functionality without requiring complex configuration or user intervention, thus managing system complexity effectively.
Solution Approach 2:
The control unit changes its operational parameters based on the connection status of the air sensor. In coupled mode, it uses real-time sensor feedback to adjust filtration operations. In uncoupled mode, it operates with predetermined parameters or last known good settings, allowing the system to adapt its complexity level based on available information.
