Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrochemical apparatuses face inefficiencies due to material buildup on electrodes, which existing cleaning methods fail to address effectively, leading to reduced function and performance.
Innovation Solution
A method involving the forced movement of liquid electrolyte across the electrode surface using pressurized gas, creating a superficial velocity of at least 0.1 m/s to dislodge material, with the gas being distributed evenly and applied through a body containing the electrolyte, ensuring consistent force and efficient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas is forced onto the liquid electrolyte surface to create movement, then material dislodges from the electrode surface, but energy consumption increases
Solution Approach 1:
The patent applies pneumatic principles by forcing gas onto the liquid electrolyte surface to generate movement. The gas flow creates disturbances in the electrolyte that generate shear forces at the electrode surface, effectively dislodging deposited material without requiring direct mechanical contact or high energy input systems.
Solution Approach 2:
The liquid electrolyte serves as an intermediary medium between the gas flow and the electrode surface. Instead of applying gas directly to the electrode or using mechanical cleaners, the electrolyte transmits the gas-induced movement to the electrode surface, where it creates sufficient shear force to remove material buildup.
2Reliability
If liquid electrolyte is moved across the electrode surface at high velocity, then material dislodges effectively, but fluid flow control complexity increases
Solution Approach 1:
The system uses gas flow to drive liquid electrolyte movement across the electrode surface. By controlling gas flow rate and distribution, the system achieves sufficient electrolyte velocity (superficial velocity of at least 0.1 m/s) to dislodge material without requiring complex mechanical pumping or flow control mechanisms.
Solution Approach 2:
The system creates dynamic fluid movement through gas injection rather than static or mechanically controlled flow. The gas forcing creates variable, high-velocity electrolyte movement that adapts to the cleaning needs, achieving effective material removal with simpler control compared to mechanically actuated systems.
3Manufacturing precision
If gas is distributed evenly over the electrolyte surface, then uniform material removal is achieved, but device complexity increases
Solution Approach 1:
The system applies gas distribution that creates locally varied flow patterns across the electrolyte surface. By distributing gas evenly or in specific patterns, different regions of the electrode receive appropriate fluid shear forces for uniform material removal, with each location experiencing optimized local conditions.
Solution Approach 2:
Gas distribution systems (such as spargers or diffusers) are used to evenly distribute gas across the electrolyte surface. This pneumatic distribution method achieves uniform electrolyte movement and consistent material removal across the electrode without requiring complex mechanical or electronic control systems.

AI summary
Provided is a method for dislodging material from a surface of an electrode. The surface of the electrode is generally covered by a liquid electrolyte. The method comprises forcing a mass of gas onto a surface of the liquid electrolyte, thereby causing movement of the liquid electrolyte in a direction generally parallel to a plane of the surface of the electrode. The movement of the liquid electrolyte imparts a force to the material on the surface of the electrode thereby causing the material to dislodge. Also provided is an apparatus for dislodging material from a surface of an electrode. The apparatus comprises an electrode generally covered by a liquid electrolyte, a body containing the liquid electrolyte with at least one liquid inlet, at least one liquid outlet, and at least one gas inlet. The at least one gas inlet is positioned such that the at least one gas inlet and the at least one liquid outlet are separated by a volume in which a portion of some of the liquid electrolyte at or near the surface of the electrode is present, and a pressurized gas source operably connected to the at least one gas inlet.
