Angled Air Compressor Motor Axis Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air compression devices are not compact enough for easy handling and use, particularly in handheld applications, due to the conventional parallel alignment of compressor and motor axes, which limits their ergonomic design and usability.
Innovation Solution
The compressor device and electric motor are positioned at an angle to each other, ranging from 10° to 80°, with a gearbox connecting them, allowing for a more compact and ergonomic design that enhances ease of use by distributing weight evenly and improving handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the compressor device and electric motor are positioned in parallel alignment, then the mechanical connection is simple, but the device size is large and handling is difficult
Solution Approach 1:
The patent transitions from a parallel alignment (one-dimensional arrangement) to an angular arrangement where the compressor axis and motor axis form an angle between 10° and 80°. This dimensional change in the spatial configuration allows the components to be positioned more compactly, reducing the overall device volume while maintaining operational simplicity through the gearbox connection.
2Volume of moving object
If the compressor device and electric motor are positioned at an angle, then the device becomes compact, but the mechanical connection becomes complex
Solution Approach 1:
The patent introduces a gearbox as an intermediary component between the electric motor and the compressor device. This mediator enables the angular positioning (reducing device size) while managing the mechanical connection complexity through standardized gear mechanisms, thus resolving the contradiction between compactness and connection simplicity.
3Ease of operation
If the compressor device and electric motor are positioned in parallel, then the structure is simple, but weight distribution is unbalanced
Solution Approach 1:
The patent employs asymmetric positioning by angling the motor axis relative to the compressor axis, creating a non-uniform weight distribution that can be optimized for ergonomic handling. This asymmetric arrangement, combined with the gearbox connection, achieves better balance and comfort without requiring overly complex structural modifications.

AI summary
An air compression device includes: a compressor device for the compression of air, wherein the compressor device has a compressor axis and the compressor axis is defined by a direction in which air is compressed by the compressor device; an electric motor for driving the compressor device, wherein the electric motor has an electric motor axis formed by an axis of rotation of the electric motor; and a transmission that mechanically connects the electric motor to the compressor device. The transmission arranges the compressor device and the electric motor at an angle to one another, and the compressor axis and the electric motor axis enclose an angle between 10° and 80°, in particular 20° and 70°, more specifically 30° and 60°.
