Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaners face limitations in sending purified air over a long distance, require additional fans for air direction control, and suffer from backflow of discharged air, leading to reduced cleaning performance and increased size.
Innovation Solution
An air cleaner design with a booster module that integrates air discharge paths, using a motor-driven display panel and gear system to control airflow direction without additional fans, allowing purified air to be sent over a larger distance and preventing backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a circulator is disposed above blowing devices to cause purified air to flow a long distance, then air circulation distance is improved, but only a portion of purified air is sent away and device complexity increases
Solution Approach 1:
The display panel is integrated with the airflow control function. The display panel itself serves as a movable component that can be tilted to control airflow direction, merging the display function with the airflow regulation function, thereby eliminating the need for a separate circulator device.
Solution Approach 2:
The display panel performs multiple functions: it displays information to the user and simultaneously controls the direction of discharged air by tilting. This multi-functional design allows the same component to serve both informational and airflow control purposes, reducing overall device complexity.
2Length of moving object
If a separate fan is added to send purified air away, then air circulation distance is improved, but device complexity and size increase
Solution Approach 1:
The air cleaner utilizes its own existing components (the display panel and the blowing device) to control and extend airflow distance, rather than adding a separate fan. The display panel's tilting capability allows the system to self-regulate airflow direction without external assistance.
3Reliability
If a partition plate or additional structure is added to prevent backflow, then air cleaning performance is improved, but device size and complexity increase
Solution Approach 1:
The display panel is designed to be movable and tiltable, allowing dynamic adjustment of airflow direction. This dynamic capability enables the system to control airflow patterns and prevent backflow through motion rather than through static partition structures.
