Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air compressors face performance and service life issues due to high motion resistance, primarily because their symmetric counterweights do not effectively facilitate smooth reciprocating motion of the piston body.
Innovation Solution
A rotating device with a gear body and counterweight, where the counterweight is horizontally divided into two halves of different weights, allowing the piston body to gather more rotational momentum at the bottom dead center, thereby enhancing the reciprocating motion and extending the service life of the air compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a symmetric counterweight is used in the conventional air compressor, then the structure is simple and easy to manufacture, but the motion resistance is great and the reciprocating motion is not smooth
Solution Approach 1:
The counterweight is designed with asymmetric mass distribution, where the left half has a different weight from the right half. This asymmetric configuration creates optimized rotational momentum that facilitates smoother reciprocating motion of the piston body, directly resolving the contradiction between structural simplicity and motion smoothness.
2Reliability
If the counterweight is divided into two halves with different weights, then the rotational momentum is optimized for smoother motion, but the manufacturing complexity increases
Solution Approach 1:
The counterweight is segmented into two distinct halves (left and right) that can be manufactured separately and then assembled together. This segmentation allows for optimized mass distribution in each half while maintaining overall structural manageability, balancing the need for complex mass distribution with manufacturing feasibility.
Solution Approach 2:
The gear body and counterweight are integrated into a single unified component through plastic molding process. This merging eliminates the need for separate assembly of these parts while incorporating the asymmetric counterweight design, thereby reducing overall device complexity despite the asymmetric mass distribution.
3Power
If the piston body conducts reciprocating motion with high motion resistance, then the compression force is sufficient, but the service life of the air compressor is reduced
Solution Approach 1:
The asymmetric counterweight design changes the dynamic parameters of the rotating device, optimizing the rotational momentum distribution throughout the cycle. This parameter optimization reduces peak motion resistance while maintaining sufficient compression force, thereby extending the service life of the air compressor through reduced mechanical stress and wear.

AI summary
An air compressor includes a rotating device pivotally connected to a piston body. The rotating device includes a gear body and a counterweight. The gear body is formed together with a counterweight, wherein the counterweight is provided with a crankshaft corresponding to the center of the gear body and a crankpin placed at a distance from the crankshaft. The counterweight is horizontally divided into two integrally formed halves, including a left half and a right half, with a common line connected between the center of the crankshaft and the center of the crankpin, wherein the left half has a weight different from the right half, so that the piston body gathers more rotational momentum from the counterweight at BDC to facilitate upstrokes, so that the piston body can conduct reciprocating motion more smoothly, and thus the service life of the air compressor can be increased.
