Solution Overview
Problem
Conventional gas accumulators with internal mechanical parts, such as pistons or bladders, are prone to mechanical failure and require frequent maintenance, which is undesirable for rapid gas fuel delivery systems.
Innovation Solution
An ionic liquid-based accumulator system that eliminates internal mechanical parts by using a high-pressure vessel with a single internal compartment, where an ionic liquid is used to pressurize gases through a liquid orifice, acting as a pressure accumulator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional accumulators use internal mechanical parts (piston or bladder) to pressurize gas, then gas pressurization function is achieved, but mechanical failure and maintenance requirements occur
Solution Approach 1:
The patent removes the bladder or piston from the accumulator system entirely. Instead of using internal mechanical parts to pressurize gas, the system extracts this function by injecting liquid (ionic liquid or conventional liquid) directly into the gas-containing chamber, eliminating the problematic mechanical components that cause failure and maintenance issues.
Solution Approach 2:
The patent replaces the mechanical pressurization system (piston or bladder) with a fluid-based pressurization system. By injecting liquid into the gas chamber, the system uses fluid pressure rather than mechanical motion to achieve gas pressurization, thereby eliminating wear, friction, and mechanical failure modes.
2Productivity
If accumulators use bladder or piston to store and deliver gas rapidly, then fast gas delivery is achieved, but mechanical failure risk increases
Solution Approach 1:
The patent extracts the bladder or piston component that enables rapid gas delivery but causes mechanical failure. By using direct liquid injection into the gas chamber, the system maintains fast gas delivery capability through controlled liquid injection rates while eliminating the mechanical parts that lead to failure.
Solution Approach 2:
The patent uses hydraulic principles by injecting liquid under pressure into the gas chamber to rapidly pressurize and deliver gas. This fluid-based approach replaces mechanical movement with hydraulic pressure control, achieving fast gas delivery through controllable liquid flow rates without mechanical wear or failure.
3Force
If accumulators use internal mechanical components, then gas pressurization is achieved, but maintenance programs are required
Solution Approach 1:
The patent removes internal mechanical components (piston or bladder) that require maintenance. By using direct liquid injection into the gas chamber, the system achieves gas pressurization without any internal moving parts, eliminating the need for maintenance programs while maintaining full pressurization capability.
Solution Approach 2:
The accumulator system is designed to be maintenance-free by eliminating mechanical parts that wear out. The liquid injection system uses simple injection valves and fluid dynamics to achieve pressurization, with no moving parts inside the accumulator chamber that require inspection, lubrication, or replacement.
