Solution Overview
Problem
Existing air processing devices face challenges in accurately determining the state of filters and other components due to reliance on single image data, leading to potential inaccuracies in assessing clogging or abnormalities.
Innovation Solution
An air processing device that utilizes an imaging unit to acquire multiple image data sets, allowing a processing unit to determine the state of components by analyzing changes over time, such as water surface height in a tray, to accurately identify abnormalities in parts like drain pumps and humidifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single image data is used to determine filter state, then device complexity is reduced, but determination accuracy deteriorates
Solution Approach 1:
The imaging unit captures images at multiple time points (before and after pump operation) to periodically observe the water surface height. This periodic imaging allows determination of pump performance by comparing state changes over time, improving measurement accuracy without requiring complex continuous monitoring systems.
Solution Approach 2:
An image is captured before the pump operates to establish a baseline water surface height. This preliminary imaging provides reference data that enables accurate determination of water discharge effectiveness by comparing with post-operation images, enhancing determination accuracy with minimal additional complexity.
2Measurement precision
If multiple image data are acquired to improve determination accuracy, then measurement precision is improved, but loss of time increases
Solution Approach 1:
Instead of continuous imaging, the system performs periodic capture at specific moments (before and after pump operation). This approach achieves accurate determination of water discharge effectiveness with minimal imaging operations, significantly reducing time loss compared to continuous monitoring while maintaining high measurement precision.
Solution Approach 2:
The system captures images at the minimum necessary time points (before and after operation) to sufficient accuracy for determining pump performance. This partial imaging approach avoids excessive time consumption while obtaining adequate measurement precision for practical maintenance decisions.
3Productivity
If single image data is used for abnormality detection, then productivity is improved, but reliability of detection deteriorates
Solution Approach 1:
The system performs quick periodic imaging before and after pump operation to detect abnormalities such as insufficient water discharge or failure to operate. This method maintains high productivity through rapid assessment while improving detection reliability by comparing state changes over time, enabling accurate identification of pump failures.
Solution Approach 2:
The system compares the water surface height before and after pump operation to provide feedback on pump performance. This feedback mechanism enhances detection reliability by identifying abnormalities through state changes, while maintaining productivity through efficient automated comparison and decision-making.
