Solution Overview
Problem
Conventional flow generators, such as fans, expose the fan to the outside, leading to safety concerns and dust accumulation, and do not effectively provide air-conditioned or purified air, especially in contaminated environments, with limited usability across temperature variations.
Innovation Solution
A flow generator design featuring upper and lower modules with integrated air treatment systems, where air is suctioned and discharged through central portions, allowing for radial airflow distribution and adjustable vertical airflow direction, minimizing fan exposure and dust accumulation, and simulating natural wind patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fan is exposed to the outside for simple airflow generation, then the device structure is simple, but the fan accumulates dust easily and safety concerns arise
Solution Approach 1:
The device is divided into an upper module with a first fan and lower module with a second fan, each handling different airflow paths. The upper module processes air from the upper suction part through its fan, while the lower module processes air from the lower suction part through its fan, separating the airflow paths to improve overall performance and reduce dust accumulation in each individual fan.
Solution Approach 2:
The fan is nested within the main body of the device, specifically the first fan is disposed in the upper module and the second fan is disposed in the lower module. This nesting arrangement protects the fans from direct exposure to the outside environment, reducing dust accumulation while maintaining compact device structure.
2Device complexity
If a single fan generates airflow, then the device structure is simple, but the airflow capacity is limited
Solution Approach 1:
The airflow generation function is segmented into two independent modules: an upper module with a first fan and a lower module with a second fan. Each fan operates independently to generate airflow, and their combined output increases the total airflow capacity of the device while maintaining relatively simple individual module structures.
Solution Approach 2:
The device merges two airflow generation systems (upper module with first fan and lower module with second fan) into a single integrated device. The airflow paths from both modules combine and are discharged through the discharge part, effectively increasing the total airflow capacity while maintaining a unified device structure.
3Device complexity
If air is discharged from upper and lower portions separately, then each airflow path is simple, but the discharged air is not well mixed
Solution Approach 1:
The airflow paths from the upper module and lower module are merged into a common discharge path. The first airflow from the upper fan and the second airflow from the lower fan both flow through the discharge part, allowing the airflows to mix together before being discharged to the outside, improving air composition uniformity.
