Axial Blower Battery Interface for Unobstructed Fluid Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axial blowers face challenges in efficiently integrating battery packs without obstructing fluid intake and providing a secure, efficient power source for operation.
Innovation Solution
The axial blower design incorporates a battery interface coupled to a distal projection upstream of the inlet, allowing battery packs to be positioned within the fluid intake volume without obstruction, and utilizes high-performance battery packs to provide up to 3000 Watts of input power to the fan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery pack is positioned within the fluid intake volume, then the power source is securely integrated and easily accessible, but it may obstruct fluid flow to the fan
Solution Approach 1:
The housing is segmented into distinct functional zones: the fluid intake volume for airflow, the battery compartment for power storage, and the outlet passage for exhaust. This segmentation allows the battery pack to be positioned within the housing without obstructing the fluid intake volume, as each component occupies its designated spatial zone. The battery compartment is specifically configured to be spaced apart from the fluid intake volume, ensuring unobstructed airflow while maintaining secure battery integration.
Solution Approach 2:
The battery pack is positioned in a dimensionally distinct location within the housing - specifically in the battery compartment that is spatially separated from the fluid intake volume. This dimensional arrangement allows both the battery and the fluid intake pathways to coexist without interference, resolving the contradiction between secure battery integration and unobstructed fluid flow.
2Power
If high-power battery packs are used to provide up to 3000 Watts of input power, then the fan can operate at high performance levels, but the battery pack size and weight increase
Solution Approach 1:
The battery compartment is designed with dynamic accessibility - it can be easily accessed by removing the end cap of the housing. This allows for quick battery pack installation and removal, enabling users to swap between different battery pack sizes based on power requirements. The dynamic design facilitates using smaller battery packs for lower power needs while accommodating high-power battery packs when maximum fan performance is required, thus managing the weight-power tradeoff flexibly.
3Reliability
If the battery interface is positioned upstream of the inlet, then the battery pack is securely mounted, but it reduces the available space for fluid intake
Solution Approach 1:
The housing interior is segmented into distinct functional zones with clear spatial boundaries. The battery interface is positioned in the battery compartment which is specifically designed to be spaced apart from the fluid intake volume. This segmentation ensures that the battery pack mounting location does not encroach upon the fluid intake space, maintaining both reliable battery mounting and adequate fluid intake volume simultaneously.

AI summary
An axial blower includes a fan, housing, and intake grate. The fan has a rotational axis. The housing surrounds the fan. The housing includes an inlet, fluid intake volume, outlet, and battery interface. The inlet is disposed at a position along the rotational axis upstream of the fan. The fluid intake volume is upstream of the inlet. The outlet is disposed at a position along the rotational axis downstream of the fan. The distal projection extends away from the inlet in an upstream direction. The battery interface is coupled to the distal projection, upstream of the inlet, and suspends a battery pack in the fluid intake volume. The intake grate is positioned between the fluid intake volume and the inlet. The intake grate permits fluid flow between the fluid intake volume and the inlet. The fluid intake volume is unobstructed between the battery interface and the intake grate.
