Problem
Existing air purification systems face challenges in efficiently delivering purifying agents to intended positions while avoiding obstacles and ensuring effective use, as they often result in wasted agents due to interference from moving objects or changes in air currents.
Innovation Solution
A system that includes an ejector and a controller, which determines the intended position of purifying agents and uses sensors to judge whether objects interfere with the agent's path, adjusting the ejection to prevent interference and ensure the agent reaches the intended position, utilizing vortex rings or air currents to efficiently purify targeted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If purifying agents are continuously ejected to ensure coverage of intended positions, then purification effectiveness is improved, but agent waste increases due to interference from moving objects
Solution Approach 1:
The system uses sensors to detect objects in the ejection path and provides feedback to the controller, which adjusts ejection operations accordingly. This closed-loop control prevents agent waste by stopping ejection when objects are detected, while maintaining purification effectiveness by resuming ejection when the path is clear.
Solution Approach 2:
The ejection system transitions from static continuous ejection to dynamic controlled ejection. The controller dynamically adjusts ejection timing based on real-time object detection, optimizing the balance between purification effectiveness and agent consumption.
2Loss of substance
If ejection timing is delayed to avoid objects, then agent waste is reduced, but purification effectiveness deteriorates due to delayed delivery
Solution Approach 1:
Real-time object detection feedback enables the system to determine optimal ejection timing. The controller uses sensor data to identify when the ejection path is clear, allowing timely ejection that avoids objects while maintaining purification effectiveness through precise timing control.
Solution Approach 2:
The system performs preliminary object detection before ejection to predict potential interference. This advance information allows the controller to plan ejection timing that avoids objects while ensuring timely delivery to intended positions.
3Measurement precision
If sensors continuously monitor the environment to detect objects, then ejection accuracy is improved, but system complexity increases
Solution Approach 1:
The sensor-controller feedback loop provides precise object detection and ejection control. The sensor monitors the environment and provides data to the controller, which adjusts ejection parameters accordingly, achieving high ejection accuracy through coordinated sensing and control.
Solution Approach 2:
The system uses ambient light sensors that are already present in many devices, leveraging existing components for object detection. This approach reduces additional hardware complexity while maintaining measurement precision through intelligent use of available sensors.

AI summary
A purifying method includes determining an intended position that ejected matter ejected from an ejecting apparatus is made to reach; judging whether an object touches the ejected matter within a period of time from ejection of the ejected matter from the ejecting apparatus to reaching of the ejected matter to the intended position based on positional information on the object, the positional information being obtained by a first sensor; and controlling, based on a result of the judging, how the ejecting apparatus ejects the ejected matter into an area including the intended position.
