Vertical Stacked Air Compressor Unit for Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air compressor units for vehicles require large installation areas due to their longitudinal configuration, which increases the space needed for mounting on vehicles, both under the floor and on the roof, and further expands when multiple units are installed.
Innovation Solution
The air compressor unit is designed with the air compressor and electric motor arranged vertically one above the other, along with a compact cooling system that includes axial fans and a centrifugal blower, reducing the necessary installation area by eliminating the need for separate power sources and power transmission mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air compressors and drive motors are coupled in series, then each air compressor can be driven by its own motor, but the dimension of the air compressor unit becomes long and the installation area increases
Solution Approach 1:
The patent transitions from a longitudinal series arrangement to a vertical stacked configuration. Multiple air compressors and drive motors are arranged one above another, utilizing the vertical dimension to reduce the horizontal footprint. This dimensional change allows the unit to maintain independent drive capability while significantly reducing the installation area on vehicle roofs or other surfaces.
2Ease of manufacture
If a large and wide area is allocated for installation, then the air compressor unit can be mounted on the vehicle, but the installation area on the vehicle increases
Solution Approach 1:
The invention rearranges components vertically to convert a two-dimensional horizontal layout into a three-dimensional vertical structure. This allows the air compressor unit to be mounted on vehicles with minimal horizontal space, enabling installation on various vehicle types without requiring large roof or floor areas.
3Productivity
If multiple air compressor units are installed in the vehicle, then the compressed air supply is increased, but the installation area further increases
Solution Approach 1:
By stacking multiple air compressor units vertically, the patent enables increased compressed air supply capacity without proportionally increasing the horizontal installation area. Multiple units can be arranged in a compact vertical column, allowing several units to occupy the space of what would traditionally be required for a single unit, thereby improving productivity while minimizing space consumption.
