Air Purifier Mode Switching for Event-Based Operational Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers with dust sensors only adjust airflow based on dust levels and cannot perform operational control corresponding to events like lifestyle patterns.
Innovation Solution
An air purifier equipped with a detection unit that periodically monitors environment information and a control unit that switches modes from learning to implementation based on specific conditions met during designated time periods, allowing for event-specific operational control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air purifier only adjusts airflow based on dust levels, then the control system remains simple, but it cannot perform operational control corresponding to events like lifestyle patterns
Solution Approach 1:
The control unit performs preliminary learning to acquire event information and determine relationships between environment information and events before implementing event-based operational control. This preliminary action allows the system to adapt to user lifestyles without requiring complex real-time decision-making logic
Solution Approach 2:
The air purifier automatically learns and adapts to user behavior patterns through the learning mode, performing self-service by acquiring event information and establishing trigger conditions without requiring manual programming or complex user configuration
2Measurement precision
If the control unit learns event patterns continuously, then event-based control accuracy improves, but the response time to actual events may be delayed
Solution Approach 1:
The control unit dynamically switches between learning mode and implementation mode based on operational conditions. In learning mode, it accumulates event data for accurate pattern recognition; in implementation mode, it rapidly responds to detected triggers, optimizing both accuracy and response speed
3Adaptability or versatility
If the air purifier operates in learning mode for an extended period, then event pattern recognition improves, but the system cannot provide reliable event-based control
Solution Approach 1:
The learning mode serves as a preliminary action phase where the control unit accumulates sufficient event information and determines reliable trigger conditions before switching to implementation mode, ensuring that event-based control only activates when adequate learning has occurred

AI summary
An air purifier (100) includes a detection unit (130) and a control unit (110). The detection unit (130) periodically detects environment information. The environment information indicates information relating to an environment around the air purifier (100). The control unit (110) determines whether or not the environment information satisfies a specific condition a plurality of times during the specific time period (Ts) corresponding to an event within a prescribed period (Ta). In a case where the control unit (110) determines that the environment information satisfies the specific condition a plurality of times, the control unit switches a mode from a learning mode to an implementation mode. In the implementation mode, in a case where the environment information meets a trigger during the specific time period, the control unit (110) performs event operational control.
