C-Shaped Piston Rotary Compressor with Orbiting Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary compressors experience malfunction due to the piston's rotation causing engagement issues with the bush, leading to damage and limited applicability for small capacity air compressors, as the piston's eccentric motion results in contact with the bush, causing linear movement and potential locking.
Innovation Solution
A rotary fluid transmission device featuring a C-shaped piston within an annular chamber, where the piston makes an orbiting motion without rotating, with a system of conduits and reservoirs for fluid flow, and a swinging circular seat with clamp arms to facilitate smooth operation, ensuring the blade moves vertically without stopping the piston's rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the piston rotates due to eccentricity between the drive shaft center and piston center, then the piston can be driven to move, but the piston contacts with the bush and moves linearly along the blade, causing engagement and malfunction
Solution Approach 1:
The invention inverts the conventional design by making the blade rotatable while keeping the piston non-rotating. The blade is equipped with a bearing at its end to support rotation, and the piston has a flat surface that contacts the blade during reciprocating motion. This inversion eliminates the piston-bush engagement problem while maintaining the necessary motion transmission.
Solution Approach 2:
The blade serves as an intermediary element between the piston and the rotating mechanism. The piston contacts the blade to transfer reciprocating motion, while the blade rotates on its bearing, mediating the motion transmission and preventing direct contact between the piston and the rotating bush.
2Reliability
If the piston makes orbiting motion without rotating, then the device operates smoothly, but requires a specific structure with annular chamber and reservoirs
Solution Approach 1:
The annular chamber serves multiple functions: it contains the piston, provides the orbiting motion path, and incorporates reservoirs for lubrication or fluid management. The conduit system integrates fluid distribution to multiple components simultaneously, reducing the need for separate systems.
3Productivity
If the blade moves reciprocately to drive the piston, then the piston contacts the blade without stopping rotation, but the blade must be rotatable with bearing support
Solution Approach 1:
Instead of making the piston rotatable as in conventional designs, the invention makes the blade rotatable. The blade is equipped with a bearing at its end to support rotation, while the piston remains stationary in terms of rotation, only performing reciprocating motion. This inversion enables continuous operation without engagement issues.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
