Linear Power Generator Dual Gas Piston Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear power generators face challenges in achieving stable power generation due to inconsistent piston movement in a gas pressure cylinder, as they rely solely on high-pressure gas supply for reciprocating motion, leading to inefficiencies and limited power generation, especially with restricted cylinder and piston stroke lengths.
Innovation Solution
The implementation of a dual high-pressure gas system where a first high-pressure gas, such as steam, initiates piston movement, and a second noncondensable gas, like air or a mix of air and steam, supplements the first gas to maintain continuous motion, optimizing gas chamber expansion and heat recovery for stable power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only first high-pressure gas (steam) is supplied to the gas chamber, then the structure is simple, but the piston movement becomes unstable and power generation is inconsistent
Solution Approach 1:
The patent combines two different gas supply systems (first high-pressure gas supply and second high-pressure gas supply) into a unified dual-gas system. The first high-pressure gas (steam) and second high-pressure gas (air or inert gas) work together in the same gas chamber to provide both initial driving force and continuous supplementary pressure, ensuring stable piston movement and consistent power generation while maintaining a relatively integrated system structure.
Solution Approach 2:
The second high-pressure gas acts as an intermediary that supplements the first high-pressure gas. When the first high-pressure gas pressure decreases during piston movement, the second high-pressure gas provides additional pressure to maintain continuous and stable piston motion. This intermediary gas ensures that the piston completes its full stroke without stopping or reversing, thereby stabilizing power generation.
2Power
If the cylinder and piston stroke lengths are limited, then the device size is compact, but the power generation output is insufficient
Solution Approach 1:
The patent changes the pressure parameter by introducing a second high-pressure gas supply system that maintains gas pressure throughout the piston stroke. Even with limited cylinder length and stroke, the dual-gas system ensures that sufficient pressure is maintained to drive the piston complete its motion and generate adequate power. The second high-pressure gas compensates for pressure loss that would otherwise occur in a compact system.
Solution Approach 2:
The second high-pressure gas supply ensures continuous useful action by maintaining gas pressure throughout the entire piston stroke. This continuous pressure support allows the piston to move smoothly from one end of the limited-stroke cylinder to the other, maximizing power generation output within the constrained physical dimensions of the device.
3Productivity
If first high-pressure gas (steam) is supplied continuously, then the piston can move continuously, but heat energy is wasted and energy efficiency decreases
Solution Approach 1:
The patent implements periodic action by supplying the first high-pressure gas (steam) only when needed to initiate piston movement, and then using the second high-pressure gas to maintain pressure during the stroke. The first high-pressure gas supply is intermittent rather than continuous, reducing heat energy waste while still ensuring continuous piston motion through the coordinated action of both gas supplies.
Solution Approach 2:
The system discards the first high-pressure gas (steam) after it has served its purpose of initiating piston movement, and recovers/uses the second high-pressure gas to maintain pressure during the remainder of the stroke. This prevents continuous heat energy input while maintaining productivity through the second gas supply.

Function Achieved in This Case
This dual gas system ensures smooth piston movement and stable power generation by efficiently utilizing heat energy, even with limited stroke lengths, by alternating the supply of high-pressure gases to enhance gas pressure and reduce energy consumption.
Implementation Method 1
supplying a first high-pressure gas into the left and right gas chambers, and keeping moving the piston by supplying a second high-pressure gas for supplementing the first high-pressure gas
Implementation Method 2
induces power generation of the electromotive coil by way of the reciprocating motion of the piston which has a permanent magnet in an axial direction
Implementation Method 3
the second high-pressure gas is a gas which is noncondensable at a condensation point of the first high-pressure gas, and is a gas which is noncondensable at a freezing point of the first high-pressure gas

AI summary
A linear power generator has a gas pressure cylinder structure which causes reciprocating motion of a piston in an axial direction by supplying a high-pressure gas alternately to a left gas chamber and a right gas chamber of a cylinder which includes an electromotive coil, and alternately applying a gas pressure in the left gas chamber and a gas pressure in the right gas chamber to the piston which includes a permanent magnet in the cylinder, and which induces power generation of the electromotive coil by way of reciprocating motion of the piston which has the permanent magnet in the axial direction. The linear power generator encourages movement of the piston by supplying a first high-pressure gas into the left gas chamber and the right gas chamber, and keeps moving the piston by supplying a second high-pressure gas for supplementing the first high-pressure gas into the left gas chamber and the right gas chamber.
