Linear Motor Compressor for Vehicle Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing compressors for vehicle height adjustment, driven by a rotary motor, result in a convex-shaped configuration, leading to increased size and compromised vehicle mountability due to their layout.
Innovation Solution
A compressor design utilizing a linear motor with a reciprocating piston and cylinder, along with an air dryer aligned along the piston's axis, reducing the overall size and improving mountability by allowing a more compact, rectilinear shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a crank mechanism driven by a rotary motor is used, then the compression unit can be driven, but the compressor becomes large in size and has a convex-shaped configuration
Solution Approach 1:
The patent replaces the rotary motor with a linear motor, substituting a mechanical rotary-crank system with a direct linear motion system. This eliminates the need for crank mechanisms and connecting rods, directly driving the piston in linear motion, thereby reducing the overall compressor size and removing the convex-shaped configuration caused by the rotary mechanism.
2Ease of operation
If a crank mechanism is used to drive the compression unit, then the piston can reciprocate, but the compressor has degraded vehicle mountability
Solution Approach 1:
The linear motor directly generates linear motion to drive the piston reciprocation, eliminating the complex crank mechanism. This simplified structure improves vehicle mountability by reducing spatial requirements and allowing more flexible installation positions within the vehicle compartment.
3Ease of manufacture
If the air dryer is disposed perpendicular to the piston axis, then it can be connected to the compression chamber, but the overall size and thickness increase
Solution Approach 1:
The patent changes the spatial arrangement by disposing the air dryer along the piston axis (longitudinal direction) rather than perpendicular to it (transverse direction). This dimensional reorientation allows the air dryer to be integrated into the existing linear structure without increasing the compressor's thickness, effectively utilizing the longitudinal space already available.
